OID 11g Fails to Start with oidmon Log Error ORA-28040 After Upgrading the OID Repository Database (DB) to 12.2 or Higher (Doc ID 2299248.1)

Last updated on AUGUST 17, 2021

Oracle Internet Directory - Version and later

Oracle Internet Directory (OID) 11g

OID worked before upgrading the Database (DB) repository, e.g., from 12.1 to 12.2 or higher.

Since upgrading OID DB to 12.2 or higher, OID fails to start with oidmon log error:
