Open Liberty configuration

Describes how Open Liberty configuration files are organized in HCL Workload Automation

To simplify administration, configuration, and backup and recovery on UNIX systems, a new default behavior has been implemented with regard to the storage of product data and data generated by HCL Workload Automation, such as logs and configuration information. These files are now stored by default in the TWA_DATA_DIR directory, which you can optionally customize at installation time.

With a similar approach, also the configuration files for Open Liberty on UNIX systems are stored in the TWA_DATA_DIR directory, while binary files are stored in TWA_home.

On Windows systems, there is no such separation and the path to Open Liberty configuration files is as follows:
On master domain managers
<TWA_home>\usr\servers\engineServer\configDropins\overrides
On Dynamic Workload Console
<DWC_home>\usr\servers\dwcServer\configDropins\overrides

Also, configuration settings, usually stored in the server.xml file, are now divided into several .xml files.

To modify Open Liberty configuration settings, first find out the .xml file to be modified and the directory where it is stored.

Open Liberty configuration files lists the files available for Open Liberty configuration.
