| Check Text (C-74554r1112466_chk) |
| If using a non-CDB database: From SQL*Plus: select instance_name, version from v$instance; If using a CDB database: To check the container database (CDB): From SQL*Plus: select instance_name, version from v$instance; To check the pluggable databases (PDBs) within the CDB: select name from v$pdbs; Check Instance Name: If the instance name returned references the Oracle release number, this is a finding. Numbers used that include version numbers by coincidence are not a finding. The database administrator (DBA) should be able to relate the significance of the presence of a digit in the SID. |
| Fix Text (F-74455r1064840_fix) |
| Follow the instructions in Oracle MetaLink Note 15390.1 (and related documents) to change the SID for the database without recreating the database to a value that does not identify the Oracle version. |
