Error:Backing up a Physical Standby database requires a recovery catalog
we have 4 node RAC and we have build the 4 node Standby database (SP32) through OEM and planning to take the RMAN backup's from OEM console.
1) OEM USER: MXK25 build the Standby setup (SP32) and he can able to schedule the backup's from OEM Console
2) OEM USER: Sysman can't able to trigger the "Schedule backup" from OEM Console through sysman user and other users in OEM Console for the same standby database (SP32)
3) for finding the root cause we are build the Standby database through OEM SYSMAN user, but sysman user also can't able to trigger the "Schedule backup" from OEM Console and other users also for the standby database (SP30)
