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

Two label records are not in the correct time sequence. Record nn1, which is the last record on log dddd1, has a later time stamp than record nn2, which is the first record on log dddd2. Also, the sequence numbers of these records are not in sequence. Some possible causes for this message are:
  • The logs are specified in the wrong order in the ALLOCATE statement, or the same log was specified twice.
  • Logs were archived in the wrong time sequence, or a log was archived twice.
  • A log was written over an older log, and the data set is not closed. This can occur when the system abends.
  • The time and date were specified incorrectly during an IPL of the operating system.
  • A log contained data other than log records.

This message is issued if command SEQCHKL RESETSEQUENCE(STOP) is specified, or if STOP is specified in the sequence checking secondary window.

CICS® VR stops the recovery and prints the reports.

  • Batch–If the sequence number was reset to zero because you are not using a journal archive control data set (JACD), specify either of these commands and then rerun CICS® VR:

    SEQCHKL RESETSEQUENCE(WARNING)    
    SEQCHKL RESETSEQUENCE(IGNORE)

    If you omitted a log, archive this log and rerun CICS® VR.

    If you are using a JACD, find out why the zero sequence number occurred. If the JACD is damaged or lost, no action is required. If a log was skipped during archiving, rerun CICS® VR after archiving the log. In other cases, check the contents of the log to see whether all records needed for recovery are present.

    If you want to accept the error message and run CICS® VR, specify one of these commands:

    SEQCHKL RESETSEQUENCE(WARNING)    
    SEQCHKL RESETSEQUENCE(IGNORE)

    Remember to restore the VSAM data sets from the backup copies before you rerun CICS® VR.

  • Online–If the sequence number was reset to zero because you are not using a journal archive control data set (JACD), specify either WARNING or IGNORE in the sequence checking secondary window.

    If you omitted a log, archive this log and rerun CICS® VR.

    If you are using a JACD, find out why the zero sequence number occurred. If the JACD is damaged or lost, no action is required. If a log was skipped during archiving, rerun CICS® VR after archiving the log. In other cases, check the contents of the log to see whether all records needed for recovery are present.

    If you want to accept the error message and run CICS® VR, specify either WARNING or IGNORE in the sequence checking secondary window.

    Remember to restore the VSAM data sets from the backup copies before you resubmit the recovery job.
