DWW0551S

A gap is encountered between record nn1 and record nn2 on log dddd when reading backward. Processing terminates.

Explanation

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 probably means that records needed for backout are 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 you specified:
  • The SEQCHKR GAPINSEQUENCE(STOP) command
  • STOP in the sequence checking secondary window
  • No option in the gap in sequence field of the sequence checking secondary window

System action

CICS® VR stops the backout and prints the reports.
