Details
| Check Text (C-21536r533014_chk) |
| From SQL*Plus: select instance_name from v$instance; select version from v$instance; 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 DBA should be able to relate the significance of the presence of a digit in the SID. |
| Fix Text (F-21535r533015_fix) |
| Follow the instructions in Oracle MetaLink Note 15390.1 (and related documents) to change the SID for the database without re-creating the database to a value that does not identify the Oracle version. |
