ADD AUDITTRAIL

If the primary transaction management process (TMP) fails before the ADD

AUDITTRAIL command completes, the backup TMP takes over and undoes the effects

of that command before processing any new requests from TMFCOM. If both TMPs

fail before the ADD AUDITTRAIL command completes, TMF also undoes the effects of

that command.

If the ADD AUDITTRAIL command returns an error, files that were preallocated when

active volumes were added might not be purged from the volumes; this occurs if the

TMP loses access to these volumes. If you attempt to add these volumes as active

again with another ADD AUDITTRAIL command, the existing files are purged before

the new ones are created.

For more information about master and auxiliary audit trails, overflow volumes, and

restore-audit volumes, see the TMF Operations and Recovery Guide.

Examples

The following ADD AUDITTRAIL command adds a master audit trail using the disk

volumes $MAT1, $MAT2, and $MAT3 for the audit-trail files:

TMF 10> ADD AUDITTRAIL MAT, &

>>>ACTIVEVOLS($MAT1,$MAT2,$MAT3), &

>>>FILESIZE 20, FILESPERVOLUME 3,&

>>>OVERFLOWVOLS($DATA1,$DATA2),&

>>>OVERFLOWTHRESHOLD 80, BEGINTRANSDISABLE 95,&

>>>RESTOREVOLS $DATA1, &

>>>AUDITDUMP ON

The next ADD AUDITTRAIL command adds an auxiliary audit trail identified as AUX01,

using the disk volume $AUX1 for the active-audit volume and $DATA3 for the overflow

and restore locations:

TMF 11> ADD AUDITTRAIL AUX01, FILESPERVOLUME 6, ACTIVEVOLS &

>>>$AUX1, OVERFLOWVOLS $DATA3, RESTOREVOLS $DATA3, AUDITDUMP ON
