What are some periodic maintenance recommendations for WebSphere in a DataStage environment?

Answer

As an example here is the path to the default profile named InfoSphere:

IBM/WebSphere/AppServer/profiles/InfoSphere


Stop the Application Server:

Execute: ./stopServer.sh <server_name> from BM/WebSphere/AppServer/profiles/InfoSphere/bin/
Ensure there are no outstanding WebSphere java processes active


Cleanup the temporary cached areas for the AppServer's profile:

Delete all of the contents (files and sub-directories) of the following directories:

- Delete all contents in the IBM/WebSphere/AppServer/profiles/InfoSphere/wstemp/ folder
- Delete all contents in the IBM/WebSphere/AppServer/profiles/InfoSphere/temp/ folder
- Delete all contents in the IBM/WebSphere/AppServer/profiles/InfoSphere/config/temp/ folder


Rename or delete the pre-existing jvm logs and ffdc logs for the Application Server jvm:

- Delete all contents in the IBM/WebSphere/AppServer/profiles/InfoSphere/logs/ffdc/
- Delete all contents in the IBM/WebSphere/AppServer/profiles/InfoSphere/logs/<server_name>/


Clear the java shared class cache for the Application Server:

Execute: ./clearClassCache.sh from AppServer's IBM/WebSphere/AppServer/profiles/InfoSphere/bin/


Afterward, check if the /javasharedresources/ sub-directory exists:

under /tmp/ filesystem:
/tmp/javasharedresources/

If the /javasharedresources/ sub-directorystill exists please remove the entire 'javasharedresources'
sub-directory (it will be recreated upon WebSphere jvm restart)


Reinitialize the osgi configuration for the AppServer:

Execute: ./osgiCfgInit.sh from IBM/WebSphere/AppServer/profiles/InfoSphere/bin/ directory


Start the WebSphere Application Server jvm:

Execute: ./startServer.sh <server_name>.sh from BM/WebSphere/AppServer/profiles/InfoSphere/bin/


Log into the Admin Console using the WebSphere primary admin user
