1. Node-oracledb Overview

The node-oracledb add-on for Node.js powers high performance Oracle Database applications.

The steps below create a Node.js installation for testing. Adjust the steps for your environment.

This node-oracledb release has been tested with Node.js 10, 12 and 14 on 64-bit Oracle Linux, Windows and macOS. Note Node.js 10.16, or later is required. The add-on can also build on some 32-bit Linux, 32-bit Windows, Solaris and AIX environments, but these architectures have not been fully tested. Older versions of node-oracledb may work with older versions of Node.js.

Node-oracledb requires Oracle Client libraries version 11.2 or later, and can connect to Oracle Database 9.2 or later, depending on the Oracle Client library version. The architecture is shown in Node-oracledb Architecture.

Node-oracledb is an add-on available as C source code. Pre-built binaries are available as a convenience for common architectures. Note the operating systems and versions of Node.js that the pre-built binaries are compatible with will change as the Node.js project evolves. The binaries are not guaranteed to be available or usable in your environment.

2. Quick Start node-oracledb Installation

  • Install Node.js from nodejs.org.

  • Install node-oracledb using the npm package manager, which is included in Node.js. If you are behind a firewall, you may need to set the proxy with npm config set proxy http://myproxy.example.com:80/.

    • Many users will be able to use a pre-built node-oracledb binary:

    • If a binary is not available, you will need to compile node-oracledb from source code:

      • Install Python 2.7 (Note: recent Node.js tools should work with Python 3).

      • Install a C Compiler such as Xcode, GCC, Visual Studio 2017, or similar.

      • Run npm install oracle/node-oracledb.git#v5.1.0, or add oracle/node-oracledb.git#v5.1.0 to your package.json dependencies. Substitute your desired GitHub tag.

  • Add Oracle 19, 18, 12, or 11.2 client libraries to your operating system library search path such as PATH on Windows or LD_LIBRARY_PATH on Linux. On macOS link the libraries to /usr/local/lib.

    • If your database is remote, then get the libraries by downloading and unzipping the free Oracle Instant Client "Basic" or "Basic Light" package for your operating system architecture.

      Instant Client on Windows requires an appropriate Visual Studio Redistributable. On Linux, the libaio (sometimes called libaio1) package is needed. On recent Linux versions, such as Oracle Linux 8, you may also need to install the libnsl package.

    • Alternatively use the Oracle Client libraries already available in $ORACLE_HOME/lib from a locally installed database such as the free Oracle XE release.

    Oracle Client libraries 19, 18 and 12.2 can connect to Oracle Database 11.2 or greater. Version 12.1 client libraries can connect to Oracle Database 10.2 or greater. Version 11.2 client libraries can connect to Oracle Database 9.2 or greater.

  • Your Node.js applications can now connect to your database. The database can be on the same machine as Node.js, or on a remote machine. Node-oracledb does not install or create a database.

    You will need to know database credentials and the connection string for the database.

After installation, learn how to use node-oracledb from the examples and the documentation.

See Troubleshooting Node-oracledb Installation Problems if you have installation issues.

3.1 Prerequisites

All installations need:

  • Oracle 19, 18, 12 or 11.2 client libraries on the machine Node.js is installed on.

    Run node -p "process.arch" and make sure to use 64-bit or 32-bit Oracle client libraries to match the Node.js architecture.

    Oracle client libraries are included in Oracle Instant Client RPMs or ZIPs, a full Oracle Client, or a database on the same machine. You only need one of these installations.

    Oracle's standard client-server network interoperability allows connections between different versions of Oracle Client and Oracle Database. For certified configurations see Oracle Support's Doc ID 207303.1. In summary, Oracle Client 19, 18 and 12.2 can connect to Oracle Database 11.2 or greater. Oracle Client 12.1 can connect to Oracle Database 10.2 or greater. Oracle Client 11.2 can connect to Oracle Database 9.2 or greater. The technical restrictions on creating connections may be more flexible. For example Oracle Client 12.2 can successfully connect to Oracle Database 10.2.

  • An Oracle Database to test node-oracledb.

    After installation of node-oracledb, your Node.js applications will be able to connect to your database. The database can be on the same machine as Node.js, or on a remote machine. Node-oracledb does not install or create a database.

    You will need to know database credentials and the connection string for the database.

If pre-built binaries are not available or desired, you need these additional tools to build from source code:

  • A compiler.

    Use Visual Studio on Windows, GCC on Linux or Xcode on macOS.

  • Python 2.7 is needed by node-gyp, which is invoked by npm. Run python --version to find the version you have. (Note: recent Node.js tools should work with Python 3).

    If another version of Python occurs first in your binary path then, when you install node-oracledb, then run npm config set python /wherever/python-2.7/bin/python or use the --python option to indicate the correct version. For example: npm install --python=/wherever/python-2.7/bin/python oracledb.

3.2 Node-oracledb Installation on Linux

There are four ways to install node-oracledb on Linux:

3.2.1 Node-oracledb Installation on Linux with Instant Client ZIP files

Follow these steps if your database is on a remote machine and either:

  • you prefer installing Instant Client ZIP files instead of RPM packages
  • or your Linux distribution uses the Debian package format, for example if you are using Ubuntu. Note: you should review Oracle's supported distributions before choosing an operating system.

Questions and issues can be posted as GitHub Issues.

3.2.1.1 Install Prerequisites

Review the generic prerequisites.

Pre-built binaries were built on Oracle Linux 6 and will require a compatible glibc.

3.2.1.2 Install Node.js

Download and extract the Node.js "Linux Binaries" package. For example, if you downloaded version 12.14.1 for 64-bit you could install Node.js into /opt:

cd /opt
tar -Jxf node-v12.14.1-linux-x64.tar.xz

Set PATH to include Node.js:

export PATH=/opt/node-v12.14.1-linux-x64/bin:$PATH
3.2.1.3 Install node-oracledb

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Install node-oracledb using the npm package manager, which is included in Node.js:

npm install oracledb

The pre-built binaries were built on Oracle Linux 6.

If a pre-built node-oracledb binary is not installable or depends on an newer glibc version, uninstall node-oracledb and build the binary from source code, see Node-oracledb Installation from Source Code.

3.2.1.4 Install the free Oracle Instant Client 'Basic' ZIP file

Download the free Basic ZIP file from Oracle Technology Network and unzip it into a directory accessible to your application, for example:

mkdir -p /opt/oracle
cd /opt/oracle
wget https://download.oracle.com/otn_software/linux/instantclient/instantclient-basic-linuxx64.zip
unzip instantclient-basic-linuxx64.zip

You will need the operating system libaio package installed. On some platforms the package is called libaio1. Run a command like yum install -y libaio or apt-get install -y libaio1, depending on your Linux distribution package manager. On recent Linux versions, such as Oracle Linux 8, you may also need to install the libnsl package. Oracle Instant Client 19 will not run on Oracle Linux 6.

If there is no other Oracle software on the machine that will be impacted, then permanently add Instant Client to the run-time link path. For example, if the Basic package unzipped to /opt/oracle/instantclient_19_6, then run the following using sudo or as the root user:

sudo sh -c "echo /opt/oracle/instantclient_19_6 > /etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig

Alternatively, every shell running Node.js will need to have the link path set:

export LD_LIBRARY_PATH=/opt/oracle/instantclient_19_6:$LD_LIBRARY_PATH

If disk space is important, most users will be able to use the smaller Basic Light package instead of the Basic package. Review its globalization limitations. Disk space can be reduced by removing unnecessary libraries and files from either the Basic or Basic Light packages. The exact libraries depend on the Instant Client version. For example, with Oracle Instant Client 19, you can optionally remove files using:

rm -i *jdbc* *occi* *mysql* *mql1* *ipc1* *jar uidrvci genezi adrci

Refer to the Oracle Instant Client documentation for details.

3.2.1.5 Optionally create the Oracle Client configuration directory

If you use optional Oracle configuration files such as tnsnames.ora, sqlnet.ora or oraaccess.xml with Instant Client, then put the files in an accessible directory, for example in /opt/oracle/your_config_dir. Then use the oracledb.initOracleClient() in your application:

const oracledb = require('oracledb');
oracledb.initOracleClient({configDir: '/opt/oracle/your_config_dir'});

Or you can set the environment variable TNS_ADMIN to that directory name.

Another alternative is to put the files in the network/admin subdirectory of Instant Client, for example in /opt/oracle/instantclient_19_6/network/admin. This is the default Oracle configuration directory for executables linked with this Instant Client.

3.2.1.6 Run an example program

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

Note: Remember to set LD_LIBRARY_PATH or equivalent first.

3.2.2 Node-oracledb installation on Linux with a Local Database or Full Client

Questions and issues can be posted as GitHub Issues.

3.2.2.1 Install Prerequisites

Review the generic prerequisites.

The ORACLE_HOME can be either a database home or a full Oracle client installation installed with Oracle's runInstaller.

For easy development, the free Oracle XE version of the database is available on Linux. Applications developed with XE may be immediately used with other editions of the Oracle Database.

3.2.2.2 Install Node.js

Download and extract the Node.js "Linux Binaries" package. For example, if you downloaded version 12.14.1 for 64-bit you could install Node.js into /opt:

cd /opt
tar -zxf node-v12.14.1-linux-x64.tar.gz

Set PATH to include Node.js:

export PATH=/opt/node-v12.14.1-linux-x64/bin:$PATH
3.2.2.3 Install node-oracledb

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Install node-oracledb using the npm package manager, which is included in Node.js:

npm install oracledb

If a pre-built binary is successfully installed but isn't usable because it depends on a different glibc version, uninstall node-oracledb and install again from source code.

If a pre-built node-oracledb binary is not installable, the binary can be built from source code, see Node-oracledb Installation from Source Code.

3.2.2.4 The default Oracle Client configuration directory

Optional Oracle client configuration files such as tnsnames.ora, sqlnet.ora, and oraaccess.xml can be placed in $ORACLE_HOME/network/admin.

Alternatively, if you use Oracle client configuration files, they can be put in another, accessible directory. Then use oracledb.initOracleClient({configDir: '/your_path/your_config_dir'}); or set the environment variable TNS_ADMIN to that directory name.

3.2.2.5 Run an example program

Set required Oracle environment variables, such as ORACLE_HOME and LD_LIBRARY_PATH by executing:

source /usr/local/bin/oraenv

Or, if you are using Oracle XE 11.2, by executing:

source /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh

Make sure the Node.js process has directory and file access permissions for the Oracle libraries and other files. Typically the home directory of the Oracle software owner will need permissions relaxed.

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

3.2.3 Node-oracledb Installation on Linux with Instant Client RPMs

Follow these steps if your database is on a remote machine and your Linux distribution uses RPM packages. Also see Installing Node.js and node-oracledb RPMs from yum.oracle.com.

Questions and issues can be posted as GitHub Issues.

3.2.3.1 Install Prerequisites

Review the generic prerequisites.

Pre-built binaries were built on Oracle Linux 6 and will require a compatible glibc.

3.2.3.2 Install Node.js

Download and extract the Node.js "Linux Binaries" package. For example, if you downloaded version 12.14.1 for 64-bit you could install Node.js into /opt:

cd /opt
tar -Jxf node-v12.14.1-linux-x64.tar.xz

Set PATH to include Node.js:

export PATH=/opt/node-v12.14.1-linux-x64/bin:$PATH
3.2.3.3 Install node-oracledb

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Install node-oracledb using the npm package manager, which is included in Node.js:

npm install oracledb

The pre-built binaries were built on Oracle Linux 6.

If a pre-built node-oracledb binary is not installable or depends on an newer glibc version, uninstall node-oracledb and build the binary from source code, see Node-oracledb Installation from Source Code.

3.2.3.4 Install the free Oracle Instant Client 'Basic' RPM

Download the latest version of the free Basic RPM from yum.oracle.com. There are channels for Oracle Linux 6 and Oracle Linux 7. The package contents are identical in both channels. The RPMs are also available from Oracle Technology Network.

Install Instant Client Basic with sudo or as the root user. You can install directly from yum.oracle.com, for example using:

sudo yum -y install oracle-release-el7
sudo yum-config-manager --enable ol7_oracle_instantclient
sudo yum -y install oracle-instantclient19.6-basic

Alternatively you can manually download the RPM and install from your local file system:

sudo yum install oracle-instantclient19.6-basic-19.6.0.0.0-1.x86_64.rpm

The link instantclient-basic-linuxx64.zip will download the latest version available from OTN.

If you have a ULN subscription, another alternative is to use yum to install the Basic package after enabling the ol7_x86_64_instantclient or ol6_x86_64_instantclient channel, depending on your version of Linux.

Using any of these methods will install the required libaio package, if it is not already present. On recent Linux versions, such as Oracle Linux 8, you may also need to manually install the libnsl package. Oracle Instant Client 19 will not run on Oracle Linux 6.

For Instant Client 19 RPMs, the system library search path is automatically configured during installation. For older versions, if there is no other Oracle software on the machine that will be impacted, then permanently add Instant Client to the run-time link path. For example, with sudo or as the root user:

sudo sh -c "echo /usr/lib/oracle/18.3/client64/lib > /etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig

Alternatively, for version 18 and earlier, every shell running Node.js will need to have the link path set:

export LD_LIBRARY_PATH=/usr/lib/oracle/18.3/client64/lib
3.2.3.5 Optionally create the Oracle Client configuration directory

If you use optional Oracle configuration files such as tnsnames.ora, sqlnet.ora or oraaccess.xml with Instant Client, then put the files in an accessible directory, for example in /opt/oracle/your_config_dir. Then use oracledb.initOracleClient() in your application:

const oracledb = require('oracledb');
oracledb.initOracleClient({configDir: '/opt/oracle/your_config_dir'});

Or you can set the environment variable TNS_ADMIN to that directory name.

Another alternative is to put the files in the network/admin subdirectory of Instant Client, for example in /usr/lib/oracle/19.6/client64/lib/network/admin. This is the default Oracle configuration directory for executables linked with this Instant Client.

3.2.3.6 Run an example program

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

Note: Remember to set LD_LIBRARY_PATH or equivalent first.

3.2.4 Installing Node.js and node-oracledb RPMs from yum.oracle.com

Node.js and node-oracledb Linux RPM packages are available on yum.oracle.com. Oracle Instant Client is also available in Oracle Linux 6 and Oracle Linux 7 channels. This means installation is simple, and can be automated.

As an example, to install Node 12 on Oracle Linux 7, run these commands:

sudo yum install -y oracle-nodejs-release-el7 oracle-release-el7
sudo yum-config-manager --disable ol7_developer_EPEL
sudo yum install nodejs node-oracledb-node12

On a vanilla Oracle Linux 7 installation the EPEL repository is not enabled so you can omit the yum-config-manager command.

For Instant Client 19, the system library search path is automatically configured during installation.

For older Instant Client versions, if there is no other Oracle software on the machine that will be impacted, then permanently add Instant Client to the run-time link path. For example, with sudo or as the root user:

sudo sh -c "echo /usr/lib/oracle/18.3/client64/lib > /etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig

Since node-oracledb is installed globally, set NODE_PATH before running applications:

export NODE_PATH=$(npm root -g)
node myapp.js

You may prefer to install node-oracledb as a normal npm package dependency.

See Node.js for Oracle Linux for details.

3.3 Node-oracledb Installation on Apple macOS

Questions and issues can be posted as GitHub Issues.

3.3.1 Install Prerequisites

Review the generic prerequisites.

The pre-built binaries were built on macOS Mojave 10.14.6.

Oracle Instant Client libraries are required on macOS. Note that Oracle Instant Client 19c and earlier are not supported on macOS Catalina 10.15: you will need to allow access to several Instant Client libraries from the Security & Privacy preference pane.

There is no native Oracle Database for macOS but one can easily be run in a Linux virtual machine, see The Easiest Way to Install Oracle Database on Apple macOS.

3.3.2 Install Node.js

Download the Node.js package for macOS 64-bit and install it.

3.3.3 Install node-oracledb

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Install node-oracledb using the npm package manager, which is included in Node.js:

npm install oracledb

If a pre-built node-oracledb binary is not installable, the binary can be built from source code, see Node-oracledb Installation from Source Code.

3.3.4 Install the free Oracle Instant Client 'Basic' ZIP file

Download the free Basic 64-bit ZIP from Oracle Technology Network and unzip it. For example in Terminal you could unzip in your home directory:

cd ~
unzip instantclient-basic-macos.x64-19.3.0.0.0dbru.zip

There are several alternative ways to tell node-oracledb where your Oracle Client libraries are, see Initializing Node-oracledb:

  • Use oracledb.initOracleClient() in your application:

    const oracledb = require('oracledb');
try {
  oracledb.initOracleClient({libDir: '/Users/your_username/instantclient_19_3'});
} catch (err) {
  console.error('Whoops!');
  console.error(err);
  process.exit(1);
}

  • Alternatively, create a symbolic link for the 'client shared library' in the node_modules/oracledb/build/Release directory where the oracledb*.node binary is. For example:

    ln -s ~/instantclient_19_3/libclntsh.dylib node_modules/oracledb/build/Release

    Instead of linking, you can also copy all the required OCI libraries, for example:

    cp ~/instantclient_19_3/{libclntsh.dylib.19.1,libclntshcore.dylib.19.1,libnnz19.dylib,libociei.dylib} node_modules/oracledb/build/Release
cd node_modules/oracledb/build/Release/ && ln -s libclntsh.dylib.19.1 libclntsh.dylib

  • Alternatively, set DYLD_LIBRARY_PATH to include the Oracle Instant Client directory. Note this variable must be set in the terminal or shell that directly invokes Node.js. The variable will not propagate to sub-shells.

  • Alternatively, create a symbolic link for the 'client shared library' in /usr/local/lib. If the lib sub-directory does not exist, you can create it. For example:

    mkdir /usr/local/lib
ln -s ~/instantclient_19_3/libclntsh.dylib /usr/local/lib

    Instead of linking, you can also copy all the required OCI libraries, for example:

    mkdir /usr/local/lib
cp ~/instantclient_19_3/{libclntsh.dylib.19.1,libclntshcore.dylib.19.1,libnnz19.dylib,libociei.dylib} /usr/local/lib/

3.3.5 Optionally create the Oracle Client configuration directory

If you use optional Oracle configuration files such as tnsnames.ora, sqlnet.ora or oraaccess.xml with Instant Client, then put the files in an accessible directory, for example in /Users/your_username/your_config_dir. Then use oracledb.initOracleClient() in your application:

const oracledb = require('oracledb');
oracledb.initOracleClient({configDir: '/Users/your_username/your_config_dir'});

Or you can set the environment variable TNS_ADMIN to that directory name.

Another alternative is to put the files in the network/admin subdirectory of Instant Client, for example in /Users/your_username/instantclient_19_3/network/admin. This is the default Oracle configuration directory for executables linked with this Instant Client.

3.3.6 Run an example program

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

3.4 Node-oracledb Installation on Microsoft Windows

There are two ways to install node-oracledb on Linux:

3.4.1 Node-oracledb Installation on Microsoft Windows with Instant Client ZIP files

Follow these steps if your database is on a remote machine, or if you already have Oracle software installed but you want node-oracledb to use a different version of the libraries.

Questions and issues can be posted as GitHub Issues.

3.4.1.1 Install Prerequisites

Review the generic prerequisites.

The pre-built binaries were built with Visual Studio 2017 and require the matching redistributable.

You may need Administrator privileges to set environment variables or install software.

3.4.1.2 Install Node.js

Install the 64-bit Node.js MSI (e.g. node-v12.17.0-x64.msi) from nodejs.org. Make sure the option to add the Node and npm directories to the path is selected.

3.4.1.3 Install node-oracledb

Open a terminal window.

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Install node-oracledb using the npm package manager, which is included in Node.js:

npm install oracledb

If a pre-built node-oracledb binary is not installable, the binary can be built from source code, see Node-oracledb Installation from Source Code.

3.4.1.4 Install the free Oracle Instant Client ZIP

Download the free 64-bit Instant Client Basic ZIP file from Oracle Technology Network. If your Node.js architecture is 32-bit, then use the 32-bit Instant Client instead. Windows 7 users: Note that Oracle 19 is not supported on Windows 7.

Unzip the ZIP file into a directory that is accessible to your application. For example unzip instantclient-basic-windows.x64-19.6.0.0.0dbru.zip to C:\oracle\instantclient_19_6.

There are several alternative ways to tell node-oracledb where your Oracle Client libraries are, see Initializing Node-oracledb:

  • Use oracledb.initOracleClient() in your application:

    const oracledb = require('oracledb');
try {
  oracledb.initOracleClient({libDir: 'C:\\oracle\\instantclient_19_6'});
} catch (err) {
  console.error('Whoops!');
  console.error(err);
  process.exit(1);
}

    If you use backslashes in the libDir string, you will need to double them.

  • Alternatively, copy the Oracle Instant Client libraries to the node_modules/oracledb/build/Release directory where the oracledb*.node binary is.

  • Alternatively, add the Oracle Instant Client directory to the PATH environment variable. The directory must occur in PATH before any other Oracle directories.

    Restart any open command prompt windows.

    To avoid interfering with existing tools that require other Oracle Client versions then, instead of updating the system-wide PATH variable, you may prefer to write a batch file that sets PATH, for example:

    REM mynode.bat
SET PATH=C:\oracle\instantclient_19_6;%PATH%
node %*

    Invoke this batch file every time you want to run Node.js.

    Alternatively use SET to change your PATH in each command prompt window before you run node.

If disk space is important, most users will be able to use the smaller Basic Light package instead of the Basic package. Review its globalization limitations. Disk space can be reduced by removing unnecessary libraries and files from either the Basic or Basic Light packages. The exact libraries depend on the Instant Client version. Refer to the Instant Client documentation.

3.4.1.5 Optionally create the Oracle Client configuration directory

If you use optional Oracle configuration files such as tnsnames.ora, sqlnet.ora or oraaccess.xml with Instant Client, then put the files in an accessible directory. For example if they are in C:\oracle\your_config_dir then use oracledb.initOracleClient() in your application:

const oracledb = require('oracledb');
oracledb.initOracleClient({configDir: 'C:\\oracle\\your_config_dir'});

If you use backslashes in the configDir string, you will need to double them.

Or you can set the environment variable TNS_ADMIN to that directory name.

Another alternative is to put the files in the network\admin subdirectory of Instant Client, for example in C:\oracle\instantclient_19_6\network\admin. This is the default Oracle configuration directory for executables linked with this Instant Client.

3.4.1.6 Install the Visual Studio Redistributables

The PATH variable needs to include the appropriate VS Redistributable:

You can also find out the version required by locating the library OCI.DLL and running:

dumpbin /dependents oci.dll

If you see MSVCR120.dll then you need the VS 2013 Redistributable. If you see MSVCR100.dll then you need the VS 2010 Redistributable. If you see MSVCR80.dll then you need the VS 2005 Redistributable.

3.4.1.7 Run an example program

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

3.4.2 Node-oracledb Installation on Microsoft Windows with a Local Database or Full Client

Questions and issues can be posted as GitHub Issues.

3.4.2.1 Install Prerequisites

Review the generic prerequisites.

The pre-built binaries were built with Visual Studio 2017 and require the matching redistributable.

The Oracle software can be either a database home or a full Oracle client installation. Make sure that PATH contains the correct binary directory, for example C:\oracle\product\12.2.0\dbhome_1\bin.

For easy development, the free Oracle XE version of the database is available on Windows. Applications developed with XE may be immediately used with other editions of the Oracle Database.

You may need Administrator privileges to set environment variables or install software.

3.4.2.2 Install Node.js

Install the 64-bit Node.js MSI (e.g. node-v10.16.0-x64.msi) from nodejs.org. Make sure the option to add the Node and npm directories to the path is selected.

3.4.2.3 Install node-oracledb

Open a terminal window.

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Install node-oracledb using the npm package manager, which is included in Node.js:

npm install oracledb

If a pre-built node-oracledb binary is not installable, the binary can be built from source code, see Node-oracledb Installation from Source Code.

3.4.2.4 The default Oracle Client configuration directory

Optional Oracle client configuration files such as tnsnames.ora, sqlnet.ora, and oraaccess.xml can be placed in $ORACLE_HOME\network\admin.

Alternatively, if you use Oracle client configuration files, they can be put in another, accessible directory. For example in C:\oracle\your_config_dir. Then use oracledb.initOracleClient({configDir: 'C:\\oracle\\your_config_dir'}); in your application or set the environment variable TNS_ADMIN to that directory name.

3.4.2.5 Run an example program

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

3.5 Node-oracledb Installation on AIX on Power Systems with Instant Client ZIP files

Questions and issues can be posted as GitHub Issues.

3.5.1 Install Prerequisites

Review the generic prerequisites.

The GCC compiler is needed.

Use GNU Make 4.1-1 or above.

Python 2.7 is needed by node-gyp.

3.5.2 Install Node.js

Download Node.js for AIX on Power Systems. For example, if you downloaded version 10.16.0 you could install Node.js into /opt:

cd /opt
gunzip -c node-v10.16.0-aix-ppc64.tar.gz | tar -xvf -

Set PATH to include Node.js:

export PATH=/opt/node-v10.16.0-aix-ppc64/bin:$PATH

3.5.3 Install node-oracledb

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Set the compiler to GCC:

export CC=gcc

Locate the GitHub tag of the desired node-oracledb version, for example v5.1.0, and use the npm package manager (which is included in Node.js) to install it.

If you have the git utility, you can install with:

npm install oracle/node-oracledb.git#v5.1.0

Otherwise install using:

npm install https://github.com/oracle/node-oracledb/releases/download/v5.1.0/oracledb-src-5.1.0.tgz

3.5.4 Install the free Oracle Instant Client 'Basic' ZIP file

Download the Basic ZIP file from Oracle Technology Network and extract it into a directory that is accessible to your application, for example /opt/oracle:

unzip instantclient-basic-aix.ppc64-19.6.0.0.0dbru.zip
mkdir -p /opt/oracle
mv instantclient_19_6 /opt/oracle

To run applications, you will need to set the link path:

export LIBPATH=/opt/oracle/instantclient_19_6:$LIBPATH

3.5.5 Optionally create the Oracle Client configuration directory

If you use optional Oracle configuration files such as tnsnames.ora, sqlnet.ora or oraaccess.xml with Instant Client, then put the files in an accessible directory, for example in /opt/oracle/your_config_dir. Then use the following in your application:

const oracledb = require('oracledb');
oracledb.initOracleClient({configDir: '/opt/oracle/your_config_dir'});

Or you can set the environment variable TNS_ADMIN to that directory name.

Another alternative is to put the files in the network/admin subdirectory of Instant Client, for example in /opt/oracle/instantclient_19_6/network/admin. This is the default Oracle configuration directory for executables linked with this Instant Client.

3.5.6 Run an example program

3.6 Node-oracledb Installation on Oracle Solaris x86-64 (64-Bit) with Instant Client ZIP files

Questions and issues can be posted as GitHub Issues.

3.6.1 Install Prerequisites

Review the generic prerequisites.

3.6.2 Install Node.js

Download the Node.js source code.

Compile and build the Node.js engine into a directory of your choice, such as /opt/node:

./configure --dest-cpu=x64 --dest-os=solaris --prefix=/opt/node
make
make install

Note: if warnings are shown for objdump and dtrace, then set PATH to include these binaries. This is most likely /usr/gnu/bin and /usr/bin, respectively.

Set PATH to include the Node.js and Node-gyp binaries

export PATH=/opt/node/bin:/opt/node/lib/node_modules/npm/bin/node-gyp-bin:$PATH

3.6.3 Install node-oracledb

If you are behind a firewall you may need to set your proxy, for example:

npm config set proxy http://myproxy.example.com:80/

Use the GNU gmake utility:

export MAKE=gmake

Locate the GitHub tag of the desired node-oracledb version, for example v5.1.0, and use the npm package manager (which is included in Node.js) to install it.

If you have the git utility, you can install with:

npm install oracle/node-oracledb.git#v5.1.0

Otherwise install using:

npm install https://github.com/oracle/node-oracledb/releases/download/v5.1.0/oracledb-src-5.1.0.tgz

If this fails due to an invalid cp -a option, you can download the node-oracledb source from GitHub. Then use node-gyp configure. Edit build/Makefile and change the cmd_copy definition cp options from cp -af to cp -pPR. Finally, run node-gyp build.

3.6.4 Install the free Oracle Instant Client 'Basic' ZIP file

Download the Basic ZIP file from Oracle Technology Network and extract it into a directory that is accessible to your application, for example /opt/oracle:

cd /opt/oracle
unzip instantclient-basic-solaris.x64-19.6.0.0.0dbru.zip

To run applications, you will need to set the link path:

export LD_LIBRARY_PATH_64=/opt/oracle/instantclient_19_6:$LD_LIBRARY_PATH_64

3.6.5 Optionally create the Oracle Client configuration directory

If you use optional Oracle configuration files such as tnsnames.ora, sqlnet.ora or oraaccess.xml with Instant Client, then put the files in an accessible directory, for example in /opt/oracle/your_config_dir. Then use the following in your application:

const oracledb = require('oracledb');
oracledb.initOracleClient({configDir: '/opt/oracle/your_config_dir'});

Or you can set the environment variable TNS_ADMIN to that directory name.

Another alternative is to put the files in the network/admin subdirectory of Instant Client, for example in /opt/oracle/instantclient_19_6/network/admin. This is the default Oracle configuration directory for executables linked with this Instant Client.

3.6.6 Run an example program

Download the example programs from GitHub.

Edit dbconfig.js and set the database credentials to your environment, for example:

module.exports = {
  user          : "hr",
  password      : process.env.NODE_ORACLEDB_PASSWORD,
  connectString : "localhost/XEPDB1"
};

Run one of the examples, such as example.js:

node example.js

3.7 Node-oracledb Installation from Source Code

Node-oracledb can be compiled from the source code.

3.7.1 Environment for compiling from source code

Some build tools are required to compile node-oracledb.

Install Python 2.7, which is required for the node-gyp utility. (Note: recent Node.js tools should work with Python 3).

  • If another version of Python occurs first in your binary path then run npm config set python /wherever/python-2.7/bin/python or use the --python option to indicate the correct version. For example: npm install --python=/whereever/python-2.7/bin/python oracledb.

  • On Windows, install the Python 2.7 MSI and select the customization option to "Add python.exe to Path".

Install a C compiler:

  • On Linux, GCC 4.4.7 (the default on Oracle Linux 6) is known to work.

  • On macOS install Xcode from the Mac App store.

  • On Windows, install a C build environment such as Microsoft Visual Studio 2017. Compilers supported by Oracle libraries are found in Oracle documentation for each version, for example Oracle Database Client Installation Guide for Microsoft Windows. Some users report that the npm windows-build-tools package has the necessary tools to build node-oracledb from source code.

The directories with the python and npm executables should be in your PATH environment variable. On Windows you can use vcvars64.bat (or vcvars.bat if you building with 32-bit binaries) to set the environment. Alternatively you can open the 'Developer Command Prompt for Visual Studio' which has environment variables already configured.

3.7.2 Installing GitHub clones and ZIP files

If you clone the node-oracledb repository, or download a zip from GitHub to build node-oracledb from source code, then you need to make sure the ODPI-C submodule is also included. Otherwise the build will fail with an error like 'dpi.h' file not found.

  • If you download a node-oracledb ZIP file from GitHub, you must separately download the ODPI-C submodule code and extract it into a odpi subdirectory.

  • When cloning the node-oracledb repository, include ODPI-C by doing:

    git clone https://github.com/oracle/node-oracledb.git
cd node-oracledb
git submodule init
git submodule update

To install, change to your application directory, and then run npm install your_dir_path/node-oracledb. Or add file:/your_dir_path/node-oracledb to your package.json dependencies.

3.7.3 Installing using GitHub branches and tags

Node-oracledb can be installed from GitHub tags and branches. The git source code utility is required for this method.

Build node-oracledb from source code by changing the package specifier so that npm downloads from GitHub. For example, to install the code from the GitHub tag v5.1.0, use a package.json dependency like:

"dependencies": {
   "oracledb": "oracle/node-oracledb#v5.1.0"
},

Alternatively, use the command:

npm install oracle/node-oracledb#v5.1.0

To install the current code on the master branch, use oracle/node-oracledb#master.

These commands will download, compile and install node-oracledb. Due to the slow download of source code from GitHub, it may take some time before compilation begins.

3.7.4 Installing from a source package

Users without the git utility can compile pre-bundled source code:

npm install https://github.com/oracle/node-oracledb/releases/download/v5.1.0/oracledb-src-5.1.0.tgz

Due to the slow download of source code from GitHub, it may take some time before compilation begins. You may prefer to download oracledb-src-5.1.0.tgz and install with:

npm install your_dir_path/oracledb-src-5.1.0.tgz

3.7.5 Installing from Oracle's repository

Oracle has a mirror of the GitHub repository source code that can be cloned with:

git clone git://oss.oracle.com/git/oracle/node-oracledb.git/
cd node-oracledb
git submodule init
git submodule update

To install, first change to a directory outside the clone directory, and then run npm install your_dir_path/your-clone-directory.

3.7.6 Creating a node-oracledb package from source code

You can create a package containing the binary module and required JavaScript files. This is equivalent to the package that is normally installed from the npm registry. Your new package can be self-hosted for use within your company, or it can be used directly from the file system to install node-oracledb.

  • Download oracledb-src-5.1.0.tgz from GitHub.

  • Extract the file: tar -xzf oracledb-src-5.1.0.tgz

  • Change directory: cd package

  • Run: npm run buildbinary

    Ignore errors about git, which is used to record some basic metadata when this command is run in git clone.

  • Optionally run the above commands on other architectures and copy the resulting package/Staging/* files to your local package/Staging directory. This will allow the final node-oracledb package to be installed on multiple architectures.

  • Run: npm run buildpackage The package oracledb-5.1.0.tgz is created.

This package can be shared or self-hosted, see Hosting your own node-oracledb Packages.

3.8 Node-oracledb Installation Without Internet Access

On a machine with access, download the node-oracledb package from npm, for example from https://registry.npmjs.com/oracledb/-/oracledb-5.1.0.tgz

This can be transferred to the desired machine and installed, for example with:

npm install your_dir_path/oracledb-5.1.0.tgz

If you are using an architecture that does not have pre-supplied binaries then you can build your own package, see Creating a node-oracledb package from source code.

Consider self-hosting the node-oracledb package inside your network, see Hosting your own node-oracledb Packages.

Alternatively, on an identical machine that has access to the internet, install node-oracle following the Node-oracledb Installation Instructions for that operating system. Then copy node_modules/oracledb and Oracle Client libraries to the offline computer. Windows users should see the next section and make sure the correct Visual Studio Redistributable is also installed.

3.8.1 Copying node-oracledb Binaries on Windows

Node-oracledb binaries can be copied between compatible Windows systems.

After node-oracledb has been built or installed on the source computer, copy the node_modules\oracledb directory to the destination computer's node_module directory.

Both computers must have the same version and architecture (32-bit or 64-bit) of Node.js.

Oracle client libraries of the same architecture as Node.js should be in the destination computer's PATH. They may alternatively be in the directory node_modules\oracledb\build\Release where the oracledb.node binary is located. Note the Oracle client library versions do not have to be the same on different computers, but node-oracledb behavior and features may then differ.

The destination computer's PATH needs to include Visual Studio Redistributables. If you have Oracle client 19 install the Visual Studio 2017 Redistributable. If you have Oracle client 18 or 12.2, install the Visual Studio 2013 Redistributable. For Oracle client 12.1 install the Visual Studio 2010 Redistributable. For Oracle client 11.2 install the Visual Studio 2005 Redistributable.

You can also find out the Redistributable required by locating the library OCI.DLL on the source computer and running:

dumpbin /dependents oci.dll

If you see MSVCR120.dll then you need the VS 2013 Redistributable. If you see MSVCR100.dll then you need the VS 2010 Redistributable. If you see MSVCR80.dll then you need the VS 2005 Redistributable.

3.9 Hosting your own node-oracledb Packages

You can host node-oracledb packages locally.

Download the node-oracledb package from npm, for example from https://registry.npmjs.com/oracledb/-/oracledb-5.1.0.tgz Alternatively, if you want to build your own binaries and node-oracledb package, see Creating a node-oracledb package from source code.

If you make the package accessible on your local web server, for example at www.example.com/oracledb-5.1.0.tgz, then your install command would be:

npm install https://www.example.com/oracledb-5.1.0.tgz

or your package.json would contain:

. . .
   "dependencies": {
      "oracledb": "https://www.example.com/oracledb-5.1.0.tgz"
   },
. . .

3.10 Using node-oracledb in Docker

Docker allows applications to be containerized. Each application will have a Dockerfile with steps to create a Docker image. Once created, the image can be shared and run.

Sample Dockerfiles for Oracle Linux are available on GitHub.

Installing Node.js in Docker

If your Dockerfile uses Oracle Linux:

FROM oraclelinux:7-slim

Then you can install Node.js from yum.oracle.com using:

RUN  yum -y install oracle-nodejs-release-el7 && \
     yum -y install nodejs && \
     rm -rf /var/cache/yum

One alternative to Oracle Linux is to use a Node.js image from Docker Hub, for example using:

FROM node:12-buster-slim

Note: you should review Oracle's supported distributions before choosing an operating system.

Installing Instant Client in Docker

Review the Oracle Technology Network or the Oracle Linux 7 channel for the latest Instant Client package available. There are various ways to install Instant Client. Three methods are shown below.

  1. Using Oracle Linux Instant Client RPMs

    If you have an Oracle Linux image:

    FROM oraclelinux:7-slim

    Then you can install Instant Client RPMs:

    RUN  yum -y install oracle-release-el7 && \
     yum -y install oracle-instantclient19.6-basiclite && \
     rm -rf /var/cache/yum

    On recent Linux versions, such as Oracle Linux 8, you may also need to manually install the libnsl package.

  2. Automatically downloading an Instant Client ZIP file

    You can automatically download an Instant Client ZIP file during image creation. This is most useful on Debian-based operating systems. (Note: you should review Oracle's supported distributions before choosing an operating system).

    The libaio (or libaio1), wget and unzip packages will need to be added manually.

    On Oracle Linux:

    RUN yum install -y libaio wget unzip

    On a Debian-based Linux:

    RUN apt-get update && apt-get install -y libaio1 wget unzip

    Then, to use the latest available Instant Client:

    RUN wget https://download.oracle.com/otn_software/linux/instantclient/instantclient-basiclite-linuxx64.zip && \
    unzip instantclient-basiclite-linuxx64.zip && rm -f instantclient-basiclite-linuxx64.zip && \
    cd /opt/oracle/instantclient* && rm -f *jdbc* *occi* *mysql* *mql1* *ipc1* *jar uidrvci genezi adrci && \
    echo /opt/oracle/instantclient* > /etc/ld.so.conf.d/oracle-instantclient.conf && ldconfig

    On recent Linux versions, such as Oracle Linux 8, you may also need to install the libnsl package.

  3. Copying Instant Client zip files from the host

    To avoid the cost of repeated network traffic, you may prefer to download the Instant Client Basic Light zip file to your Docker host, extract it, and remove unnecessary files. The resulting directory can be added during subsequent image creation. For example, with Instant Client Basic Light 19.6, the host computer (where you run Docker) could have a directory instantclient_19_6 with these files:

    libclntshcore.so.19.1
libclntsh.so.19.1
libnnz19.so
libociicus.so

    With this, your Dockerfile could contain:

    ADD instantclient_19_6/* /opt/oracle/instantclient_19_6
RUN echo /opt/oracle/instantclient_19_6 > /etc/ld.so.conf.d/oracle-instantclient.conf && \
    ldconfig

    The libaio or libaio1 package will be needed.

    On Oracle Linux:

    RUN yum install -y libaio

    On a Debian-based Linux:

    RUN apt-get update && apt-get install -y libaio1

    On recent Linux versions, such as Oracle Linux 8, you may also need to install the libnsl package.

Installing node-oracledb and your application

Include node-oracledb as a normal dependency in your application package.json file:

  . . .
  "scripts": {
    "start": "node server.js"
  },
  "dependencies": {
    "oracledb" : "^4"
  },
  . . .

The packge.json and application file can be added to the image, and dependencies installed when the image is built:

WORKDIR /myapp
ADD package.json server.js /myapp/
RUN npm install

CMD exec node server.js

Using Oracle Net configuration files and Oracle Wallets

Optional Oracle Net Configuration files (like tnsnames.ora and sqlnet.net) and files that need to be secured such as Oracle wallets can be mounted at runtime using a Docker volume. Map the volume to the network/admin subdirectory of Instant Client so the TNS_ADMIN environment variable does not need to be set. For example, when the Wallet or configuration files are in /OracleCloud/wallet/ on the host computer, and the image uses Instant Client 19.6 RPMs, then you can mount the files using:

docker run -v /OracleCloud/wallet:/usr/lib/oracle/19.6/client64/lib/network/admin:Z,ro . . .

The Z option is needed when SELinux is enabled.

Example Application in Docker

This example consists of a Dockerfile, a package.json file with the application dependencies, a server.js file that is the application, and an envfile.list containing the database credentials as environment variables.

If you use Oracle Linux, your Dockerfile will be like:

FROM oraclelinux:7-slim

RUN  yum -y install oracle-release-el7 oracle-nodejs-release-el7 && \
     yum -y install nodejs oracle-instantclient19.6-basiclite && \
     rm -rf /var/cache/yum

WORKDIR /myapp
ADD package.json server.js /myapp/
RUN npm install

CMD exec node server.js

An equivalent Dockerfile that uses a Node.js image is:

FROM node:12-buster-slim

RUN apt-get update && apt-get install -y libaio1 wget unzip

WORKDIR /opt/oracle

RUN wget https://download.oracle.com/otn_software/linux/instantclient/instantclient-basiclite-linuxx64.zip && \
    unzip instantclient-basiclite-linuxx64.zip && rm -f instantclient-basiclite-linuxx64.zip && \
    cd /opt/oracle/instantclient* && rm -f *jdbc* *occi* *mysql* *mql1* *ipc1* *jar uidrvci genezi adrci && \
    echo /opt/oracle/instantclient* > /etc/ld.so.conf.d/oracle-instantclient.conf && ldconfig

WORKDIR /myapp
ADD package.json server.js /myapp/
RUN npm install

CMD exec node server.js

For either Dockerfile, the package.json is:

{
  "name": "test",
  "version": "1.0.0",
  "private": true,
  "description": "Docker Node.js application",
  "scripts": {
    "start": "node server.js"
  },
  "keywords": [
    "myapp"
  ],
  "dependencies": {
    "oracledb" : "^5"
  },
  "author": "Me",
  "license": "UPL"
}

The application server.js contains code like:

. . .
connection = await oracledb.getConnection({
  user: process.env.NODE_ORACLEDB_USER,
  password: process.env.NODE_ORACLEDB_PASSWORD,
  connectString: process.env.NODE_ORACLEDB_CONNECTIONSTRING
});
const result = await connection.execute(
  `SELECT TO_CHAR(CURRENT_DATE, 'DD-Mon-YYYY HH24:MI') AS D FROM DUAL`,
  [],
  { outFormat: oracledb.OUT_FORMAT_OBJECT }
);
console.log(result);
. . .

The environment variables in envfile.list are used at runtime. The file contains:

NODE_ORACLEDB_USER=hr
NODE_ORACLEDB_PASSWORD=<hr password>
NODE_ORACLEDB_CONNECTIONSTRING=server.example.com/orclpdb1

The image can be built:

docker build -t nodedoc .

Alternatively, if you are behind a firewall, you can pass proxies when building:

docker build --build-arg https_proxy=http://myproxy.example.com:80 --build-arg http_proxy=http://www-myproxy.example.com:80 -t nodedoc .

Finaly, a container can be run from the image:

docker run -ti --name nodedoc --env-file envfile.list nodedoc

The output is like:

{ metaData: [ { name: 'D' } ],
  rows: [ { D: '24-Nov-2019 23:39' } ] }

4. Installing Older Versions of Node-oracledb

Pre-built node-oracledb 3 and 4 binaries are available for some platforms and Node.js versions. Review the release tags for availability. You can compile the add-on for other platforms or versions.

The node-oracledb 4.2 installation steps are in the version 4.2 INSTALL guide.

The node-oracledb 3.1 installation steps are in the version 3.1 INSTALL guide.

To get an old add-on you must explicitly use its version when installing, for example:

npm install [email protected]

or your package.json could contain:

. . .
   "dependencies": {
      "oracledb": "4.2.0"
   },
. . .

5. Troubleshooting Node-oracledb Installation Problems

Read the Node-oracledb Installation Instructions.

Google anything that looks like an error.

If npm install oracledb fails:

  • Review the error messages closely. If a pre-built node-oracledb binary package is not available for your Node.js version or operating system, then change your Node.js version or compile node-oracledb from source code.

  • Was there a network connection error? Do you need to use npm config set proxy, or set http_proxy and/or https_proxy?

  • Use npm install --verbose oracledb. Review your output and logs. Try to install in a different way. Try some potential solutions.

  • When compiling node-oracledb from source, do you have Python 2.7? Run python --version.

  • When compiling node-oracledb from source, do you have an old version of node-gyp installed? Try updating it. Also try deleting $HOME/.node-gyp or equivalent.

  • Try running npm cache clean -f and deleting the node_modules/oracledb directory.

If creating a connection fails:

  • If you got DPI-1047: Cannot locate an Oracle Client library, then review any messages, the installation instructions, and see Initializing Node-oracledb.

  • If you got DPI-1072: the Oracle Client library version is unsupported, then review the installation requirements. Node-oracledb needs Oracle client libraries 11.2 or later. Note that version 19 is not supported on Windows 7.

  • Does your Node.js architecture (32-bit or 64-bit) match the Oracle client library architecture? Run node -p 'process.arch' and compare with, for example, dumpbin /headers oci.dll (on Windows), file libclntsh.dylib (macOS) or file libclntsh.so.* (Linux).

  • On Windows, do you have the correct VS Redistributable? Review the Windows install instructions.

  • On Windows, check the PATH environment variable includes the Oracle client libraries. Ensure that you have restarted your command prompt after you modified any environment variables.

  • Do you need system privileges to set, or preserve, variables like PATH, e.g. an elevated command prompt on Windows, or sudo -E on Linux?

  • Do you have multiple copies of Oracle libraries installed? Is the expected version first in PATH (on Windows) or LD_LIBRARY_PATH (on Linux)?

  • On macOS, did you install Oracle Instant Client libraries in /usr/local/lib?
