Why Audit-Trail Files Stay Pinned on a Volume

In the STATUS AUDITTRAIL display, the line labeled, “First pinned file:” refers to the

oldest audit-trail file that cannot yet be reused or purged from the active or overflow-

audit volume. There is always at least one active audit-trail file on disk, so the status

display always shows a file name on this line. The display also shows the reason that

the file is pinned; these are described next.

Reason: Active transaction(s)

Meaning. An active transaction may have sent an audit record to this audit-trail file.

The audit-trail file remains on the active or overflow-audit volume in case the

transaction aborts, in which case the file will be needed by the backout process.

Action. Use the STATUS TRANSACTIONS command to see the status of all

transactions. If a transaction remains in the active, aborting, or hung state, you may

have to back it out manually. See Controlling Individual Transactions on page 3-21.

If the transaction is active and you do not want to abort it, check the STATUS TMF

display to see if the audit trail is nearing the begin-transaction-disable threshold; if it is,

consider increasing the audit-trail capacity, as described in Responding to Audit-Trail

Overflow on page 3-5.

If the problem persists, check the EMS log to see if the backout process has reported

any errors while undoing the transaction.

See Maintaining Transactions on page 2-15 and Viewing EMS Messages on

page 2-28.

Reason: Current file

Meaning. This audit-trail file is currently receiving audit records.

Action. No action is required.

(Dumped) —The file has been copied to archive media by the audit

dump process. An available file is not marked as dumped because it

must have been dumped to become available.

(Dumping)—The file is being copied to archive media by the audit

dump process.

(Not Dumped)—The file has not yet been copied to archive media.

(Not Dumping) —The file will not be dumped because the audit trail

was not configured for dumping when the file became full. This file

can only be dumped manually, using a backup or duplication

program.
