Error description

  • Error Description￘
    An IMS extract is done.
    
    One of the dependent segments is unkeyed. The segments are
    extracted in order as expected.
    
    The problem occurs on the import.
    
    The segments, after the import, are reordered.
    
    The dbd definition for this segment looks like:
    
          SEGM    NAME=xxxxxxxx,PARENT=yyyyyyyy,BYTES=40,PTR=T,
             RULES=(LLL,FIRST),
    
    The LOADTYPE = 2 as they want to just backfill an existing
    database.
    
    It would appear that File Manager makes no attempt to maintain
    sequence and just mindlessly inserts, which in this case based
    on the dbd exactly reverses the segment sequence.

    * PROBLEM DESCRIPTION: Twin segments extracted from one        *
    *                      database and loaded into another are    *
    *                      not in the same sequence in the loaded  *

    *                      The problem occurs when the insert      *
    *                      rule for the twin segment is FIRST or   *
    *                      HERE.                                   *
    ****************************************************************
    * RECOMMENDATION: Apply the provided PTF.                      *
    ****************************************************************
    The Extract and Load does not maintain the sequence of twin
    segments when the insert rule for these segments is FIRST or
    HERE.
    

Problem conclusion

  • FM/IMS has been modified to maintain the sequence of twin
    segments when they are extracted from one database and loaded
    into another.
