Custom configuration

WDT allows you to create or extend the pre-installed type definitions, model filters, variable injectors, and target environments. Starting with WDT 1.10.0, these additional configuration files can be stored outside the $WLSDEPLOY_HOME/lib directory. This allows the files to remain in place if the WDT installation is moved or upgraded to a new version.

To use a separate configuration directory, set the WDT_CUSTOM_CONFIG environment variable to the directory to be used for configuration. For example:

$ export WDT_CUSTOM_CONFIG=/etc/wdtconfig

The customized configuration files should be named and organized the same way they would be under the $WLSDEPLOY_HOME/lib directory. For example:

        *.json  (injector files)
        *.json  (typedef files)
            *.py  (filter files)

This is a full set of files that can be configured. You will need only to add the files you have created or extended. Details for each configuration type are found at:

The WDT tools will look for each configuration file under $WDT_CUSTOM_CONFIG if specified, then under $WLSDEPLOY_HOME/lib.

Example: Extending a type definition

To extend the WLS type definition, follow these steps:

  • Create a directory to use for custom configurations, such as /etc/wdtconfig.
  • Define the WDT_CUSTOM_CONFIG environment variable to point to that directory.
  • Copy the file $WLSDEPLOY_HOME/lib/typedefs/WLS.json to the $WDT_CUSTOM_CONFIG/typedefs directory and rename it, for example MY_WLS.json.
  • Edit MY_WLS.json with any required changes.
  • Run the tool referencing the name of the new type definition, for example:
$ createDomain.cmd -oracle_home /wls12213 -domain_type MY_WLS ...
