I tried to drop and rebuild this and it worked, except that about 50 other items then because invalid and would not validate. Looking online, I found a suggestion to run catproc, so I tried that and ended up back where I started, with the SYS.ALERT_QUE stuff invalid again.

The only issue I ran into in the pre-upgrade steps was that it complained that job_queue_processes was set to 0. The suggestion was to either remove it from the spfile or set it to a non-zero value. I chose to remove it.

I am in the process of restoring the database from the last backup, but I am not sure how to proceed as I'm sure if I just try to upgrade again, it will fail with the same error.

Does anyone have any idea what is causing this and how to fix / avoid it?

Stats:
Original version: 12.1.0.2
New version: 19.4.0.0
O/S: Red Hat 7
