Explanation
A sequence number gap was found between two label
records when switching logs; the sequence numbers are not in sequence. The
records are in the correct time sequence. That is, record
nn1,
which is the last record on log
dddd1, has an earlier time
stamp than record
nn2, which is the first record on log
dddd2.
This message could mean that records needed for backout are missing. Some
possible causes are:
- A log was omitted when specifying the logs to CICS® VR, or logs are specified in the wrong
order.
- A log was skipped during archiving.
- Label records were skipped over by a selective archiving program; records
needed for backout might be skipped also.
- The journal archive control data set (JACD)
is damaged or inaccessible, causing the wrong sequence numbers to be used
on label records.
- A log had data other than log records.
This message is issued if command SEQCHKL
GAPINSEQUENCE(WARNING) is specified, or if WARNING is specified in the sequence
checking secondary window.
System action
CICS VR continues the backout.
User response
- Batch–If a log was missing, archive this log and rerun CICS VR.
If
all logs are present, find out why there is a gap in the label records. (Check
the contents of the log to see whether all records needed for backout are
present.) Correct the error and rerun CICS VR.
Remember to restore the
VSAM data sets from the backup copies before you rerun CICS VR.
