DWW0550W A gap is encountered between record nn1 and record nn2 on log dddd when reading backward. Processing continues.
section
A sequence number gap was found between two label
records in log dddd; the sequence numbers are not in sequence.
The records are in the correct time sequence. That is, record nn2,
which precedes record nn1 on the log, has an earlier time
stamp. This message means that records needed for backout are probably missing.
Some possible causes are:
- A log was skipped during archiving.
- Label records were skipped over by a selective archiving program; records needed for backout might also be skipped.
- 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 SEQCHKR GAPINSEQUENCE(WARNING) is specified, or if WARNING is specified in the sequence checking secondary window.

- 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.)
Remember to restore the VSAM data sets from the backup copies before you rerun CICS VR.
- Online–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.) Remember to restore the VSAM data sets from the backup copies before you resubmit the recovery job.
