Descriptions of Event Messages
Effect
The effect of this event depends on which recovery process was used.
For backout, this event message is accompanied by a second event (171 or 172) that
indicates the effect.
For volume or file recovery, this event message is accompanied by event 171. The file
is marked either “redo-needed” or “undo-needed” and is no longer available for
transaction processing.
Recommended Action
If the backout process was involved and the event message is accompanied by event
172, then some type of recovery action may be required, depending upon the status
indicated by event 172. If the status is “ignored,” then no recovery action is needed
immediately (although the affected file is no longer consistent). If the status is “retried,”
then no recovery action is needed unless the transaction becomes “hung.” In the latter
case, refer to the Guardian Procedure Errors and Messages Manual for corrective
action for the indicated file-system error number.
If either the volume recovery process or the file recovery process was involved, then
the event is serious and file recovery is needed.
