Just the other day I hit the unpublished Bug 16445132: DBMS_SCHEDULER PROBLEM WITH DATABASE MIGRATION VIA EXPDP/IMPDP.
It affects Scheduler Jobs that were created to end with a corresponding Scheduler Window.
Here’s an excerpt of a Data Pump Logfile:
ORA-39083: Object type PROCOBJ failed to create with error:
ORA-27469: STOP_ON_WINDOW_EXIT is not a valid job attribute
Actually, the correct attribute name for this procedure would be “stop_on_window_CLOSE” instead of “stop_on_window_EXIT”. The latter is an attribute of the JOB_DEFINITION object type which in my eyes is inconsistently named in respect to the SET_ATTRIBUTE procedure.
The bug is fixed, but as of Nov. 2014 there is no one-off patch for version 18.104.22.168. The existing workaround is to ignore the error and recreate the job after the import .
If you run into this bug and it bugs you a lot, the other option is to ask for a patch for this issue.
