Parameter
Description
BKP
Indicates if the Backup procedure is beginning or ending. Valid value are:
START — Backup procedure of Media database has started.
END — Backup procedure of Media database has ended.
The steps for implementing the CTTTRB utility are as follows:
Run the utility before backup of the Media database and the Trace file. In this run, set the BKP parameter to START. This run of the utility marks the most recently filled record in the Trace file.
Perform the necessary backups. Any local site backup procedures can be used to perform this task.
After the backup has been successfully completed, run the CTTTRB utility with the BKP parameter set to END. This run marks all Trace file records before the record marked in the previous run of the utility (Step 1 above).
