Applications: Monitoring and Recovery Monitoring the Status of TMF

Monitoring the Status of TMF

To monitor TMF using TMFCOM:

1.At a TACL prompt:

> TMFCOM

2.At the TMFCOM prompt:

~ STATUS TMF

Note. The STATUS TMF command presents status information about the audit dump, audit trail, and catalog processes. Thus, in addition to the general TMF information, the STATUS TMF command combines information from the STATUS AUDITDUMP, STATUS AUDITTRAIL, and STATUS BEGINTRANS commands. However, information from the other STATUS commands (STATUS DATAVOLS, STATUS OPERATIONS, STATUS SERVER, and STATUS TRANSACTION) does not appear in the STATUS TMF display.

A TMFCOM report summarizing the current activity of the TMF subsystem, audit trails, and the audit dump and catalog processes is displayed. For example:

TMF Status:

System: \SAGE, Time: 6-Jul-1994 11:08:06

State: Started

Transaction Rate: 0.10 TPS

AuditTrail Status:

Master:

Active audit trail capacity used: 55%

First pinned file: $MAT1.ZTMFAT.AA000044

Reason: Active transaction(s).

Current file: $MAT1.ZTMFAT.AA000045

AuditDump Status:

Master: State: enabled, Status: active, Process $X545,

File: $MAT2.ZTMFAT.AA000042

BeginTrans Status: Enabled

Catalog Status:

Status: Up

For an explanation of the TMF state in this display, see TMF States on page 13-3.

Monitoring Data Volumes

To display information about the data volumes for which the TMF subsystem generates audit records on behalf of transactions performed on those volumes, at a TMFCOM prompt, type:

~ STATUS DATAVOLS

To control which volumes are displayed, use the STATE, AUDITTRAIL, and RECOVERYMODE parameters.

The normal operating state for a data volume is STARTED, which indicates that the volume is ready to process TMF transactions. Audited requests are allowed for data volumes in this state only where transaction processing is enabled within the subsystem.
