PK46593: HP LOAD GETS ABENDU3770 WHEN PROCESSING PHYSICAL SEQUENTIAL SORT FOR A (P)HDAM WHICH CONTAINS MULTIPLE DSG.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• HP Load gets ABENDU3770 when processing physical sequential sort
  for a (P)HDAM which contains multiple DSG because it
  underestimates the value of FILSZ for DFSORT.
  

Local fix

• Specify SORTWK DD statements to circumvent the problem.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM IMS High Performance Load   *
  *                 for z/OS Version 2 Release 1 (FMID=H1IM210)  *
  ****************************************************************
  * PROBLEM DESCRIPTION: HP Load gets ABENDU3770 when processing *
  *                      physical sequential sort for a (P)HDAM  *
  *                      due to setting inadequate parameter     *
  *                      values for DFSORT.                      *
  ****************************************************************
  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  1. HP Load gets ABENDU3770 when processing physical sequential
     sort for a (P)HDAM which contains multiple DSG because it
     underestimates the value of FILSZ for DFSORT.
  2. HP Load gets ABENDU3770 when processing physical sequential
     sort for a (P)HDAM which has segment larger than 27KB.
     This is because that the HP Load passes the parameter of
     LENGTH=27994 to DFSORT.
  

Problem conclusion

• 1. HP Load improved the calculation method of FILSZ parameter.
  2. The module HPSRSRT0 has been modified to specify the maximum
     record size to LENGTH parameter correctly.

  ========================
  IMS High Performance Load for z/OS Version 2 Release 1 User's
  Guide SC18-9222-02 ( SC18922202 ) should be changed as follows:
  ----------------------------------------------------------------
  2.0 High Performance Load
  2.2 Operating instructions
  2.2.2 JCL requirements
  
   SORTWKnn DD
     These are intermediate storage data sets used by DFSORT. If
     SORT=YES is specified, you can define these data sets and
     adjust the size of work space that is used for the sort
     process. You can specify multiple data sets, 'nn' showing
     its serial number. This specification is optional. If you do
     not specify the statement, DFSORT allocates the data sets
  |  dynamically with sizes estimated based on the size of RAA.
  |  If the size of RAA is extremely large or small, you should
  |  specify SORTWKnn DD explicitly.
  
     For more information on how to code SORTWKnn DD ...
  
  ----------------------------------------------------------------
  2.2.3 Control statements
  2.2.3.23 SORT control statement
  
     Specifies whether to run the physical sequential sort
     processing before loading. This control statement is
     optional. If you do not explicitly specify this control
     statement, SORT=NO is used.
     :
     If you specify SORT=COND, High Performance Load determines
     whether to run the physical sequential sort processing
     according to the criteria listed  above. Therefore, in some
     cases, it does not sort input unloaded data sets even if the
     sort process is required for the reload process. In such
     a case, you have to run PSSR before reloading or specify
     SORT=YES instead of SORT=COND.
  
  |  Note: If a work space of DFSORT needs to be adjusted, please
  |  specify the SORTWKnn DD statements.
