Error description

  • DB2 uses two control files to track information about configured
    AUTOMATIC STORAGE path. The files are named SQLSGF.1 and
    SQLSGF.2 and are located in the local database directory. There
    might be external cicrumstances, like file system problems,
    where these files could become corrupted (i.e file size is 0
    byte).
    
    In such a scenario a db2 backup command might still succeed
    leaving the customer under the impression that this is a good
    backup image. However, such a backup can not be restored
    anymore. DB2 restore might fail with the following message in
    db2diag.log:

    This APAR is opened to enhance DB2 backup code to detect such
    problems by doing some additional sanity checks when performing
    the DB2 backup.
