We are upgrading from 12.1.3 to 13.3. About 30 minutes in the script, the upgrade fails with "ORA-20000: ORU-10027: buffer overflow, limit of 1000000 bytes"
We tried to disable DBMS_OUTPUT and even make it unlimited with no luck. We also did a logon trigger to disable the server output and it still gives that error at the same spot. Has anyone else seen this issue before on oracle?
