  This happened in a development lpar and caused some problems
  before we found the cause. We need to turn on TRANSTAT soon
  for our production-systems.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All IMS V13 users of the type-2 UPD TRAN     *
  *                 command.                                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: CPRI, LPRI, NPRI and PARLIM values are  *
  *                      erroneously updated during UPD TRAN     *
  *                      commands when a combination of batch &  *
  *                      non-batch transactions are specified.   *
  ****************************************************************
  * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF      *
  ****************************************************************
  IMS V13 base code has logic to correct existing non-FP batch
  transactions with CPRI¬=0, LPRI¬=0, NPRI¬=0 or PARLIM¬=65535.
  The logic used to make this correction tests the PSB of the
  transactions during validation of the update attributes.  If
  the PSB is a non-FP batch PSB additional checks are made to
  determine if CPRI, LPRI, NPRI are non-zero or if PARLIM is not
  equal to 65535, values which are invalid for non-FP batch
  transactions.  If this invalid criteria is found in an existing
  transaction involved in the UPD TRAN command the update
  attribute structure is updated to simulate the user had entered
  the valid values for the transaction.  However, if non-batch
  transactions are also being updated (ex. UPD TRAN NAME(*)
  SET(aaaaa(vvvv)) ) then the CPRI, LPRI and NPRI are set to zero
  and the PARLIM set to 65535 for all transactions.  This
  erroneous update condition occurs for any UPDATE TRAN updating
  batch & non-batch transactions if the invalid priority values or
  parlim value are discovered.  The problem is not limited to
  SET(aaaaa(vvvv)) where 'aaaaa' is an attribute and 'vvvv' is the
  value to be assigned, this also happens for STOP(xxx) and
  START(xxx) updates.
  

Problem conclusion

• GEN:
  KEYWORDS:
  
  *** END IMS KEYWORDS ***
  
  DFSTRS00 is updated to remove the correcting code such that
  CPRI, LPRI, NPRI & PARLIM are updated only if the user specifies
  them on the UPD TRAN command.  CREATE TRAN & UPDATE TRAN will
  continue to validate these values and their proper combinations
  with other attributes but if they are not specified on an UPD
  TRAN by the user the existing values will no longer be verified.

  The IMS V13 Commands, Volume 2, Chapter 30, "UPDATE
  commands" under "UPDATE PGM command" in the section labeled
  "Keywords" for keyword BMPTYPE insert the following paragraph
  after the first paragraph:
  
      "When a program is updated to BMPTYPE(Y) the scheduling
       priority of the transactions referencing the program
       must be set to zero and the parallel processing limit
       must be set to 65535.  All transactions that reference
       the program must be updated to set CPRI, LPRI and NPRI
       to 0 and PARLIM to 65535."
