  This APAR fixes the following issues of IMS Online
  Reorganization Facility.
  1. Storage shortage may occur during ORF 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. ORF can occasionally get ABENDS878-10 with GETMAIN processing
     of buffers when IMSDALIB DD is specified in ORF step.
     A lot of buffers are allocated below 16M when opening
     IMSDALIB DD. Code has been changed to reduce number of
     buffers for IMSDALIB.
  
  3. ORF can occasionally get ABENDS878-10 with GETMAIN processing
     of buffers when the all following conditions are met.
      1) BMP application updates the database in the Copy phase.
      2) IMS OSAM database
      3) DBDS block size is large.
      Code has been changed to reduce number of database buffers
      when updating OSAM database in the Copy phase.
  

Problem conclusion

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