These utilities optionally generate accounting records that are based on the data. If you include the DATABASE record in the VMSPOOL CONFIG file, the utilities run automatically.
A summary of the database utilities and what they do follows:
Generates the database and updates it periodically with new information about spool files.
Uses the information that is stored in the database to create a file containing type C0/AB accounting records.
Sends the accounting records created by VMLDBB to CP.
Purges database records that contain obsolete spool-file information.
