PH00905: RUNNING THE CICS STAT TRANSACTION PROGRAM DFH0STAT RESULTS IN DFHSR0001 S0C7 DFH0STSY WHEN SELECTING MVS TCBS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• You are running CICS TS 4.2 and issue the STAT transaction.
  When you select the "Dispatcher MVS TCBs" option, you receive
  the following error:
  .
  DFHSR0001 An abend (code 0C7/AKEA) has occurred at
            offset X'0000CDB6' in program DFH0STSY.
  .
  The failing instruction is  the following COMPARE DECIMAL:
  .
     F930 3018 C018 | CP      X'18'(X'4',R3),X'18'(X'1',R12)
  .
  Each operand must be in signed-packed-decimal format, but
  in this case operand 1 - R13+18 pointed to 000005DC
  which is not valid format, causing the data exception.
  .
  Our code is attempting to retrieve the current task number
  associated with the JS- Job Step TCB- field name is:
     DSRDS-TCB-CICS-TASK
  Routine dfhkeds_inquire_mvstcb is where we retrieve this
  information, and the code is not checking if the TCA address
  is zero.  This causes the code to go to low core + 109 to
  retrieve the task number. In this case location 109 contained
  the value 0005DC.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: Abend S0C7 occurs when running the STAT *
  *                      transaction.                            *
  ****************************************************************
  When running the STAT transaction, and choosing the "Dispatcher
  MVS TCBs" option, the user experiences an S0C7 abend. This is
  because field TAS_TCA_ADDRESS, which is used to retrieve the
  transaction task number contains zeroes.
  
  Keyword(s): KEDS_TCA_TASK_NUMBER ABENDS0C7
  

Problem conclusion

• DFHKEDS has been altered so that, if TAS_TCA_ADDRESS contains
  zeroes, the transaction task number will be set to zeroes also,
  to prevent an S0C7 data exception.
