  This APAR fixes the following issues of IBM IMS HALDB Toolkit
  V1.1.
  1. Storage shortage may occur during HTK execution when DBDs
     containing large amounts of metadata are used in an
     IMS-managed ACB environment.
     The IMS catalog API (DFS3CATQ) loads DBDs with large amounts
     of metadata below the 16MB line in an IMS managed ACB
     environment, resulting in storage shortages.
     Code has been changed to specify the new DFS3CATQ parameter
     EXTATTR=NONE, as provided in IMS APAR PH39492.
     If EXTATTR=NONE is specified, DBDs without metadata will be
     loaded.
  
  2. HTK can occasionally get ABENDS878-10 with GETMAIN processing
     of buffers when the all following conditions are met.
      1) ONLINE(Y) is specified in IHCSYSIN.
      2) BMP application updates the database in the Copy phase.
      3) IMS OSAM database
      4) DBDS block size is large.
      Code has been changed to reduce number of database buffers
      when updating OSAM database in the Copy phase.
  
  3. When dynalloc failure occurred for the restart data set,
     only the first job that allocated the restart data set
     is included in the messages in MSGPRINT DD and traces
     in TRACE DD. However when multiple jobs allocated the restart
     data set, it is better to include all job names in traces to
     make it easier to investigate.
  

Problem conclusion

• Code has been changed to fix the issues described in this APAR.
