Set up Work Manager Shutdown Trigger in WebLogic Server 10.3.4 Using WLST

WebLogic Server's Work Managers provide a way to control work and allocated threads. You can set different scheduling guidelines for different applications, depending on your requirements.
There is a default self-tuning Work Manager, but you might want to set up a custom work manager in some circumstances: for example,
- when you want the server to prioritize one application over another
- when a response time goal is required, or
- when a minimum thread constraint is needed to avoid deadlock.
The Work Manager Shutdown Trigger is a tool to help with stuck threads in which will do the following:
- Shut down the Work Manager.
- Move the application to Admin State (not active).
- Change the Server instance health state to failed.
Example of a Shutdown Trigger set on the config.xml for your domain:
