Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When DFSXRBLD is processing the DMB reference list against the
  DDIR chain when a catatlog DDIR is incountered the DMB name in
  the reference list is being overlaid with the catalog alias
  prefix if something other then the default alias is defined.

  ****************************************************************
  Csect DFSXRBLD of module DFSXRBB0 contains the logic to relocate
  the secondary list. To perform this function, the database name
  in the DMB reference list is compared to the database name of
  the active DDIR chain. In this comparision process, the first
  four bytes of the database name in the DMB reference list was
  incorrectly replaced by the catalog alias in the case where an
  alias catalog database was enabled and the loaded DMB was not a
  catalog database. Routine REFLLOC should skip the catalog alias
  logic in the case the loaded DMB is not a catalog database and
  the compared DDIR from the system DDIR chain is not a catalog
  database. This logic change would prevent message DFS564I from
  being issued correctly.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  Code has been modified in Csect DFSXRBLD of module DFSXRBB0
  to compare the database name of the loaded DMB to a catalog data
  base name from the system DDIR chain only if the loaded DMB is
  a catalog database and the compared DDIR from the DDIR chain is
  also a catalog database. In addition, an alias DDIR address is
  returned from routine REFLLOC if the loaded DMB is a catalog
  database and a catalog alias has been specified.
