Why Audit-Trail Files Stay Pinned on a Volume
Reason. Might be needed to recover datavol volume-name
volume
Meaning. This audit-trail file contains audit records that may be needed by the volume
recovery process to reapply transactions to the specified data volume. The file is kept
on the active or overflow-audit volume so that if volume recovery is needed, the audit-
trail file does not have to be restored from archive media: this means that the data
volume’s recovery mode is configured as ONLINE.
Action. Use the STATUS DATAVOLS command to make sure the data volume is
started for transaction processing.
If the audit trail is reaching overflow capacity, you can use the ALTER DATAVOLS
command to change the recovery mode for the data volume to ARCHIVE. This
change releases the audit-trail files needed by the data volume for volume recovery: if
volume recovery is needed, it will probably require audit records stored on audit dump
tapes. Archive mode is allowed only if the audit trail for this data volume is configured
for audit dumping. See Changing the Data Volume Configuration on page 3-11 for
more information.
Reason: Might be needed to restart TMF
Meaning. This audit-trail file contains control information needed by TMF to restart
after a system failure. The control information is typically written to the current file
within 10 minutes, which clears this condition. If there is no audited activity, however,
control records are not generated; in this case, the condition remains until audited
activity resumes.
Action. If the status of this file does not change within 10 minutes and the output of
STATUS TMF commands indicates that audit activity is occurring, check the EMS log
for TMF errors.
Reason: Not dumped
Meaning. An audit dump process has been configured for this audit trail, and this file
has not yet been copied to dump media.
Action. Use the STATUS AUDITDUMP command to check on the audit dump process:
•
If the audit dump process was disabled, issue an ENABLE AUDITDUMP
command.
•
If an audit dump process is active and you are doing tape dumps, make sure that
all tape mount requests are satisfied.
•
If an audit dump process is active and you are doing disk dumps, make sure that
your disk has enough space for the audit-trail file.
See Maintaining Audit Dumps on page 4-1 for more information on maintaining audit
dumps.
