| Review the DBMS software library directory and note other root directories located on the same disk directory or any subdirectories. |
If any non-DBMS software directories exist on the disk directory, examine or investigate their use. If any of the directories are used by other applications, including third-party applications that use the DBMS, this is a finding.
Only applications that are required for the functioning and administration, not use, of the DBMS should be located in the same disk directory as the DBMS software libraries.
If other applications are located in the same directory as the DBMS, this is a finding.
For databases located on mainframes, confirm that the database and its configuration files are isolated in their own DASD pools.
If database software and database configuration files share DASD with other applications, this is a finding.
