I’ve spent the last couple of days playing around with the scheduler enhancements in Oracle 12c.
I guess the big news is the new “script jobs”, which are pretty cool. This kind-of passed me by until Brynn Llewellyn mentioned them at UKOUG in his Multitenant presentation, at which point I made a note to check them out.
I’ve been having some trouble with the “BACKUP_SCRIPT” jobs up until a few minutes ago. My problem was I couldn’t see what the stdout/stderr text was, so I couldn’t determine why there were not working. The “$ORACLE_HOME/scheduler/log” directory was empty and there were no messages in the trace files or alert log. Then I stumbled upon the new columns added to the ALL_SCHEDULER_JOB_RUN_DETAILS view. The OUTPUT column, not surprisingly, gives you the output from the scripts. Once I could see the error message it took me a few seconds to fix the issue and Bingo! 🙂
The new job types are a nice addition, allowing you to run file-based scripts or incline scripts much more easily that before.
