Catalog

One catalog process pair, named $XCAT, in each HP NonStop server runs TMF. The

primary catalog process is created by the TMP when you start TMF, and the process

pair is terminated when you stop TMF.

The catalog process queries and manipulates entries in the TMF catalog in response

to:

•

Requests from other TMF processes

•

TMFCOM commands such as ADD TAPEMEDIA and ALTER DUMPS

•

Requests from the labeled tape server ($ZSVR), which is invoked by certain

TAPECOM and MEDIACOM commands (such as USE TAPE or NEXT TAPE) and

by the tape process when the operator mounts a scratch tape

If the catalog process stops or abends while TMF is running, the TMP automatically

restarts it.

Audit Dump

When the automatic audit dumping feature is configured and enabled, an audit dump

process copies filled audit-trail files from the active-audit volume to the configured

archive media.

An audit dump process runs only when an audit trail is full or when a rollover is initiated

manually with a NEXT AUDITTRAIL command. If the audit dump process stops or

abends while TMF is running, the TMP automatically restarts it. When it is finished, the

audit dump process is terminated.

Audit Overflow

When the automatic audit dumping feature is turned on, an audit overflow process

copies the earliest audit-trail file from the associated active-audit volume to an

overflow-audit volume whenever audit-trail usage reaches the configured overflow

threshold.

An audit overflow process runs only when an audit-trail file is full and cannot be

dumped, or when a rollover is initiated manually with a NEXT AUDITTRAIL command.

If the audit overflow process stops or abends while TMF is running, the TMP

automatically restarts it. When it is finished, the audit overflow process is terminated.
