PI87812: DBD/PSB/ACB COMPARE DOES NOT COMPARE METADATA WHEN NOCOMP=IMSREL IS SPECIFIED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• DBD/PSB/ACB Compare does not compare metadata with NOCOMP=IMSREL
  when one member is generated by IMS V11 or earlier and the
  other is
  generated by IMS V12 or later.
  
  It is wrong behavior because the source of one member which has
  metadata is not same as the source of the other member which
  does not
  have metadata. IMSREL is valid when two members are generated
  from the same source but the version of IMS that generated the
  two members is different.

  This APAR fixes a behavior of NOCOMP=IMSREL option of
  DBD/PSB/ACB Compare utility when it compares two members with
  the following condition.
  One member is generated by IMS V11 or earlier and the other is
  generated by IMS V12 or later and it has a metadata.
  In this case, the utility does not compare metadata with
  NOCOMP=IMSREL even if two members are generated by the
  different sources.
  It is a wrong behavior because NOCOMP=IMSREL is used when two
  members are generated from the same source but the version of
  IMS that generated the two members is different.
  This APAR fixes the utility to compare metadata with
  NOCOMP=IMSREL.
  NOCOMP=METADATA is used not to compare metadata.
  
  This APAR also fixes the following problems of DBD/PSB/ACB
  Compare utility.
  
   -VERSION= statement in the source-level compare reports does
    not have comma ',' even if VERSION= statement is not a last
    statement.
   -The utility wrongly detects difference in SEGMENT= parameter
    in XDFLD statement when SEGMENT= parameter is omitted because
    the index target segment type is the index source segment and
    one member has metadata and the other does not have metadata.
   -The utility ends with ABEND0C4 when STARTAFTER= parameter in
    FIELD statement has over 26 words.
   -The utility does not compare CASEIDTYPE= parameter in DFSCASE
    statement if CASEID= parameter in DFSCASE statement has over
    19 words.
