APAR status

  • Closed as program error.

Error description

  • Converting a HADR Standby database to a Standard database and
    using this database, will generate new logfiles. These
    logfiles will get archived normally. When this database gets
    restored later on, to set it up again as HADR Standby,
    FirstArchNum will not be reset in the SQLOGCTL.LFH file during
    the restore.
    If the Primary database has not produced as many logfiles as the
    Standby database before and the HADR Primary is switched to
    Standby and back to Primary, the wrong value for FirstArchNum
    will make it to the Primary. This stops the Primary from
    archiving logfiles afterwards.
    

Local fix

  • Drop the database on the HADR Standby before the restore.
