The Application Performance Analyzer Listener-started task must be started for it to become operational. Once started, workstation users with the proper authority can connect to any active Application Performance Analyzer-started task using the Application Performance Analyzer GUI.
If you have not re-IPLed after making changes to parmlib as described in step 6 you can start the Listener by entering the command 'S procname' on the system console, where procname is the Application Performance Analyzer Listener-started task procedure name.
When you re-IPL your system, the Application Performance Analyzer Listener-started task is automatically started.
