2 Routine Maintenance
This section describes how to perform routine maintenance on your TMF system’s
components. It addresses the following topics:
For information about establishing your TMF environment, determining what system
resources TMF needs to protect your database, and creating or deleting a TMF
configuration, see the TMF Planning and Configuration Guide.
You can use the TMFCOM command interface to perform TMF maintenance.
Procedures described in this guide show use of TMFCOM commands.
Maintaining Audit-Trail Files
TMF normally maintains audit-trail files without your intervention. When an audit-trail
file gets full, TMF directs audit records to the next available audit-trail file; this activity is
known as a “rollover.” TMF requires two available audit-trail files at all times: one that
is currently receiving audit information, and one available for rollover. If audit dumps
are configured for the audit trail, TMF then generates requests for dump media and a
dump process to begin.
Your role in maintaining audit-trail files is to monitor the status display and make sure
that tapes or disks are available for audit dumps, if your system is configured with an
audit dump process.
This section describes how to monitor the audit-trail status display, and explains what
action may be needed based on the information in that display. Information about how
to perform audit dumps appears in Section 4, Audit Dumps.
Audit-trail maintenance tasks that you do only occasionally are described in
Responding to Audit-Trail Overflow on page 3-5.
