Rollover Errors

If TMF cannot find a preallocated or an available file for an audit-trail rollover, it

generates the following EMS message:

Unable to find an available audit trail file for name audit

trail.

Use the STATUS AUDITTRAIL command to determine why there are no files available

for the rollover. See Why Audit-Trail Files Stay Pinned on a Volume on page 2-5 for

suggestions on freeing audit-trail files for reuse.

If the current audit-trail volume goes down and you issue a NEXT AUDITTRAIL

command for this audit trail before the TMP detects that the volume is down, the TMP

terminates without issuing an EMS message. To correct this condition, bring the audit-

trail volume back up and issue a START TMF command to resume transaction

processing.

Maintaining Data Volumes

When TMF starts, it automatically starts all data volumes that are enabled for

transaction processing. You monitor the status of enabled data volumes to make sure

that they are operating and configured properly.

This section describes how to monitor the data volume status display, and explains

what action may be needed based on the information in that display. For information

on disabling and reenabling data volumes, and changing the data volume

configuration, see Section 3, Occasional Operations.

Displaying Data Volume Activity

Use the STATUS DATAVOLS command to check the status of one or more data

volumes. This information tells you which data volumes are available for transaction

processing, and displays several key attributes of the data volume configuration. Any

user allowed to use TMFCOM can use this command when TMF is running. Here is

an example of the STATUS DATAVOLS command display when no options have been

used:
