Upgrade to 18c db slow and cannot query dba_autotask_client

edited Jun 5, 2020 11:12PM in Database Install/Upgrade/Opatch (MOSC) 1 commentAnswered ✓

We have an Oracle database that we are upgrading to 18c (windows server 2016). After the upgrade the disks are spinning and there is no activity. I suspect auto taks are running and got turned on by DBUA. I cannot run the following query because it hangs and never returns.

SELECT client_name, status FROM dba_autotask_client;

Any ideas? What could be hitting the drives? Why does this query just freeze?

Thank you
