For Backup and Restore 2:

If you use CLASS TAPECATALOG DEFINEs with CATALOG ON, the DSM/TC
catalog manager (MEDIADBM) keeps track of the tapes used as part of a back up
job. During a restore job, the correct set of tapes can be retrieved from DSM/TC.
However, DSM/TC does not maintain information about the objects and files
backed up on each tape. To list each object backed up on tape,
see Managing Jobs on page 4-5

You can use the MEDIACOM RECOVER DISKFILE command to restore objects
from tape to disk instead of the RESTORE command. The MEDIACOM RECOVER
DISKFILE command invokes:

A BRCOM RESTORE command for OSS or SQL/MX objects

The RESTORE utility (T9074) for Enscribe and SQL/MP objects

TMF furnishes transaction protection, database consistency, and database recovery
critical in high-volume transaction processing. It sustains high performance for online
transaction processing (OLTP) applications, in addition to online query processing
(OLQP) activities, batch processing applications, and decision-support systems.

For Backup and Restore 2:
Because all SQL/MX files are audited, use TMF online dumps as the primary method
for preserving SQL/MX objects. Preserving files by using the BACKUP command is not
effective for recovery if any files are open during the backup operation. Even if you use
the OPEN option, the image saved during the dump of the database might not be
consistent. For more information about using TMF online dumps with SQL/MX, see the
SQL/MX Installation and Management Guide.
