PRGP-01201
The database rollback cannot be completed in a rolling manner because the source home at "{0}" contains more RAC Two-Stage rolling patches compared to the target home at "{1}".
Cause
The RAC Two-Stage rolling patches enabled in the source home are more than in the target home and therefore cannot be rolled back in a rolling manner.
Action
Reissue the command specifying the '-nonrolling' option to complete the rollback in a non-rolling manner.
