A gap is encountered when switching logs and reading forward. Record nn1 on log dddd1 precedes record nn2 on log dddd2. Processing continues.

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 might mean that records needed for recovery are missing. Some possible causes are:
  • A log was omitted when specifying the logs to CICS® VR in the ALLOCATE statement, 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 recovery 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 contained 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 recovery.
