Understanding Audit-Trail File Names

An audit-trail file name consists of three parts: volume, subvolume, and file ID:

$active-audit-volume

The system manager uses the ADD AUDITTRAIL or ALTER AUDITTRAIL

command to specify from 1 to 16 active-audit volumes for the audit trail.

ZTMFAT

All TMF audit trails are stored in the ZTMFAT subvolume.

AA | BB...PPnnnnnn | ZTMFnnnn

The system manager uses the ADD AUDITTRAIL command to create the audit

trail as the master audit trail (MAT) or as an auxiliary audit trail. TMF assigns the

prefix AA to MAT files and the prefixes BB through PP to files in each of the

auxiliary audit trails; it also assigns a 6-digit audit-trail sequence number.

Any preallocated audit-trail files have the file ID ZTMFnnnn. When these files

become active audit-trail files, TMF renames them using the proper prefix and

sequence number for the audit trail. The 4-digit sequence number of a

preallocated file has no relationship to the audit-trail file order.

Displaying Audit-Trail Activity

Use the STATUS AUDITTRAIL command to display the current activity and status of

one or more audit trails. Any user allowed to use TMFCOM can use this command

when TMF is running.

Here is an example of the STATUS AUDITTRAIL command display when the DETAIL

option has been used:

TMF 78> STATUS AUDITTRAIL, DETAIL
