PH23427: LIU UNDER IMS ADMIN TOOL MAY CAUSE DYNALLOC FAILURE IN CATALOG SPACE ANALYSIS WHEN IT FINDS UNUSED DFSHDBSC DFSMDA MEMBER

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• LIU module which runs under the IMS Administration Tool to show
  Catalog Space Analysis causes dynamic allocation failure for
  DFSHDBSC DD when the following conditions met:
  1. The IMS catalog database is registered to the RECON data set.
  2. DFSHDBSC DFSMDA member is created in the MDA library but it
  includes non-existent IMS catalog partition definition data set.
  
  LIU module should not do dynalloc DFSHDBSC when the IMS catalog
  database is registered to the RECON data set.

  ****************************************************************
  When LIU runs under IMS Administration Tool to obtain IMS
  environment information, the dynamic allocation error occurs
  for DFSHDBSC DD.
  
  It is caused when the following conditions meet.
  
  -IMS Catalog database is registered to the RECON data set and
  UNREGCATLG definition is not set in the DFSDF member.
  
  -DFSMDA member has the definition of the catalog partition
  definition data set which DD name is DFSHDBSC, however, it
  points non-existent data set.
  
  
  When IMS Catalog database is registered to the RECON data set,
  DFSHDBSC for the catalog partition definition data set is not
  used. Regardless of it is used, LIU always do dynamic
  allocation DFSHDBSC DD when LIU finds the definition. If the
  system has unused definition, LIU should not do dynamic
  allocation it.
  
  This APAR fixes LIU not to do dynamic allocation DFSHDBSC DD
  when IMS Catalog database is registered to the RECON data set.
