Descriptions of Event Messages
ZTMF-TKN-RCOV-ERROR-INDEX
contains an integer specifying an audit-trail index value (zero indicates the master
audit trail; 1 through 15 indicate auxiliary audit trails).
ZTMF-TKN-RCOV-ERROR-SNO
contains an integer specifying an audit-trail, file-sequence number.
ZTMF-TKN-RCOV-ERROR-RBA
contains an integer specifying a relative byte address (rba) within the file.
Effect
This event message is accompanied by event 358. The file is marked either “redo-
needed” or “undo-needed” and is no longer available for transaction processing.
Recommended Action
The event is serious and file recovery is needed. When TMF is recovering a file to a
new location and encounters a purge audit record for the source object, unintended
consequences can result if TMF queues the audit record to the disk process.
Specifically, TMF will purge the target object if the operator or subsystem control
process (SPI requester) did not specify one of the following options in the RECOVER
FILES command:
•
TOFIRSTPURGE
•
TIME or TOMATPOSITION, indicating a location earlier than this record’s location
in the audit trail.
To avoid this purge, TMF does not queue the record to the disk process but, instead,
terminates the recovery.
To recover from this error, issue the RECOVER FILES command again for this object,
specifying either the TOFIRSTPURGE option or a TIME or TOMATPOSITION location
before this record in the audit trail. This action will retrieve a consistent copy of the
object.
