Ensure Old Password Versions Are Not Used

AltaNivel 1Automatizadaoracle-db

Descripción

No password versions (hashes) prior to 12c should be allowed for user authentication. Run on the database host as the Oracle software owner with ORACLE_HOME, ORACLE_SID and PATH set; connects to the CDB root with 'sqlplus -S / as sysdba' (OS authentication) so CDB_/GV$ views cover all open PDBs.
