Displaying TMF Status
To recover from this situation, increase the audit-trail capacity as described in
Responding to Audit-Trail Overflow on page 3-5. It is important that you determine the
cause of the capacity problem so you can correct it and make sure it does not recur.
The information in the STATUS TMF display can notify you of a potential problem on
the system, which you can usually prevent by taking some action. Table 1-1 describes
the information in the STATUS TMF display.
Note. Additional information can appear in this display if your system is running the HP
NonStop™ Remote Database Facility subsystem that guarantees Zero Lost Transactions
(RDF/ZLT). For details about this information, see the discussions of the ALTER AUDITTRAIL,
STATUS AUDITTRAIL, and STATUS TMF commands in the TMF Reference Manual. Some of
this information is also displayed by the INFO TMF command, described under Displaying
Configuration Attributes on page 1-6 of this manual.
Table 1-1. Understanding the STATUS TMF Display
Heading Meaning
TMF Status State—The operational state of TMF, as described in Table 1-2.
Transaction Rate—The number of transactions being committed or
aborted per second.
TMPWaitTimer—The current setting of the TMP wait timer, which may
be: AUTO (the time that the TMP waits is calculated based on
transaction activity and is reset every 10 seconds), OFF (the TMP
processes each request as it arrives), or nnnnn Microseconds (the
duration that TMF waits before waking to process further requests).
See the TMF Reference Manual for more information about the TMP
wait timer.
AuditTrail Status The percentage of the audit trail that is full and the name of the audit-
trail file currently receiving audit records. If one or more audit-trail files
are pinned on disk, the name of the oldest such file and the reason
that it cannot be deleted are given. See Maintaining Audit-Trail Files
on page 2-1 for more information on audit-trail status.
AuditDump Status Whether the audit dump process is configured and enabled; also, the
name of the audit dump process and the audit-trail file currently being
dumped. See Section 4, Audit Dumps
for more information on audit
dump status.
BeginTrans Status Whether new transactions can begin, shown as “ENABLED” or
“DISABLED.” If new transactions are disabled, a reason is given.
See Maintaining Transactions
on page 2-15 for more information.
