4 Audit Dumps
Audit dumps preserve audit-trail files for use by the file recovery process. The audit
dump process copies audit-trail files from disk to tape, or from disk to disk when the
files are full and no longer needed by outstanding transactions or volume recovery.
This section explains how to prepare for and make audit dumps, and includes these
topics:
You can use the TMFCOM command interface as illustrated by the procedures
described in this guide.
Maintaining Audit Dumps
It is important to know how often audit-trail files get full on your TMF system so you can
plan for audit dumps. Dumping audit-trail files on a regular basis is the best way to
keep audit trails from overflowing, and it secures your database in case of a system or
media failure.
Your role in maintaining audit dumps is to monitor the status displays and prepare
dump media.
Displaying Dump Attributes
Use the INFO TMF or INFO AUDITDUMP command to become familiar with the audit
dump configuration. See Displaying Configuration Attributes
on page 1-6 for
a description of the audit dump configuration attributes.
Displaying Dump Activity
Use the STATUS TMF or STATUS AUDITDUMP command to view the status of any
audit dump processes configured on your system.
The audit dump status display indicates whether the audit dump process is active or
inactive, and whether the process is enabled or disabled. If a dump is in progress, the
display shows the audit dump process name and the name of the file being dumped.
