WebSphere Application Server Liberty Base configuration
Describes how WebSphere Application Server Liberty Base 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 WebSphere Application Server Liberty Base 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 WebSphere Application Server Liberty Base 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 WebSphere Application Server Liberty Base configuration
settings, first find out the .xml file to be modified and the directory where it is
stored.
| Configuration file | Functionality |
|---|---|
| TWA_DATA_DIR/usr/servers/engineServer/configDropins/overrides | |
| authentication_config.xml | Authentication settings |
| datasource.xml | Datasource settings |
| host_variables.xml | Hostname and port settings |
| jvm.options | Settings for Java Virtual machine, such as HeapSize |
| ports_variables.xml | Hostname and port settings |
| ssl_variables.xml | SSL connections and certificates |
| wauser_variables.xml | Authentication settings |
| TWA_DATA_DIR/usr/servers/engineServer/resources/security | |
| TWSServerKeyFile.jks | WebSphere Application Server Liberty Base key store file, containing security keys |
