Symptoms

Scenario:

1) Dataguard 11g with logical standby database

2) Customer implemented DBMS_SCHEDULER  as SYS on both primary and standby site.
The job is listed in DBA_SCHEDULER_JOBS on primary/standby before a switchover/failover-action.

3) Customer performed dataguard switchover.

4) After the switchover the job is gone from view DBA_SCHEDULER_JOBS on NEW primary site,
however the job is visible in DBA_OBJECTS.

 Since the job is still available in dba_objects recreating or dropping the job fails with:


ORA-27477: "SYS.MON_TMP_UNDO_JOB" already exists.

Changes

After upgrade from 10g to 11g  the jobs doesn't work anymore on the new primary in case of a switchover/failover.
This worked fine in 10g.
