DWW0561S
A record with a zero sequence number is found when switching logs and reading backward. Record nn2 on log dddd2 precedes record nn1 on log dddd1. Processing terminates.

Explanation

A label record with a zero sequence number was found, and the record before it on the log (nn1) does not have the maximum sequence number (232-1). Record nn1 is the last record on log dddd1, and the zero record is the first record on log dddd2. Some possible causes are:
  • The sequence number was reset to zero by CICS®. If you are not using a journal archive control data set (JACD), CICS resets the sequence number at every cold start and warm start. CICS VR functions correctly in this situation.
  • A log data set is omitted when specifying the logs and the next log started with a zero record.
  • A zero sequence number occurred because the JACD is damaged or lost. CICS VR functions correctly in this situation.
  • A log was skipped during archiving, and the next log started with a record with a zero sequence number.
  • A log had data other than log records.
This message is issued if you specified:
  • The SEQCHKL RESETSEQUENCE(STOP) command
  • STOP in the sequence checking secondary window
  • No option in the reset sequence field of the sequence checking secondary window

System action

CICS VR stops the backout and prints the reports.
