Installation_Guide_Configuration
Contents | Preface | Introduction | Architecture | Environment | Standalone | Deployment | Configuration
Configuration is achieved via an XML file called settings.xml. The
default is [TOMCAT_HOME]/settings.xml. The directory location can be
specified by setting the environment variable WATS_PROPERTIES.
Note
To get the default settings file, start the server and then stop it. If the settings.xml file is not available, the default settings will be created. You can then edit it.
This configuration file is broken into several different sections. Each section is independent of the other sections and can occur in any order within the document.
Note
Relative paths are from the tomcat home.
These are settings used by the controller application for global things like locations and names.

<data-file-storage>/mnt/wats/datafiles</data-file-storage>
<!-- The server side storage directory for temp script files -->
<tmp-file-storage>/mnt/wats/tmpfiles</tmp-file-storage>
<!-- The server side storage directory for agent files to be sent to agents -->
<jar-file-storage>/mnt/wats/jars</jar-file-storage>
<!-- name of this instance (no spaces). used in timing table names. -->
<instance-name>prod</instance-name>
<!-- The baseUrl for the controller. Must include the context e.g. tank) -->
<controller-base-url>http://localhost:8080/tank</controller-base-url>
<!-- if this instance is a standalone instance and should not start agents automatically. -->
<standalone>false</standalone>
