Shutdown/failover routine to fully disable java gateway connections

Scenario:

Failover Primary to Backup device, but something is wrong with the Backup that could not be started as the Primary, so you have to fail back to the Primary.

Problem:

When this happens, we have noticed that the Java Process that is running at the OS level for the Java Gateway, has not fully shutdown.

When the Primary starts back up, it cannot start the Java Gateway processes because the ports are already in use.

Workaround:

We have to kill that Java processes at the OS level, so the port is released for the Java Gateway Services to fully start.

During the Namespace/Production shutdown/failover it is not fully stopping the java processes.

Besides writing a script or updating ZSTART/ZSTOP to ensure that the java processes are killed it would be nice if the system already had this built in.
