After running EPMA_CreateAndStartVIPResource.bat or EPMA_StopAndDeleteVIPResource.bat, you can run this command from the command line to check the status of the VIP resource:
crsctl status resource epmavip -v
A status of STATE=ONLINE indicates that the resource is running correctly. After you run EPMA_StopAndDeleteVIPResource.bat, the VIP resource should no longer exist.
