Has anyone successfully upgraded 12.1.0.2 to 18.0.0 (specifically 18.4) on AIX 7.1 Power 64?
I've been trying to simply upgrade a single-instance non-CDB database to 18.4. But everytime it errors out. "catupgrd0.log" throws a couple ORA-01422 errors and then eventually exits out near the end of completion.
