APAR status

• Closed as program error.

Error description

• In a CICS region where TMON automatically forcepurges several
  tasks, the region abends randomly after this error:
  
  DFHTD0382 CICSCANA The output pointer for queue TF3E does not
  match the contents of the intrapartition data set (DD
  name DFHINTRA).

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: FORCEPURGE causes later termination     *
  *                      of CICS with message DFHTD0382.         *
  ****************************************************************
  CICS terminates with message DFHTD0382 because
  Transient Data has been left in an inconsistent state due
  to an earlier FORCEPURGE of a transaction.
  
  Some time before the DFHTD0382 termination,
  a CICS application was working with Intrapartition
  Transient Data, and issued EXEC CICS xxx TD.
  CICS TD processing entered a SUSPEND for the TD lock (TDIOLOCK).
  The transaction was force purged while suspended waiting
  for the TD lock.
  CICS returned to the application with EIBRESP(ERROR) and
  left Transient Data control blocks in an inconsistent state.
  
  The CICS region continued processing for some time before the
  TD inconsistency was detected.
  
  IBM Documentation warns that FORCEPURGE can cause CICS to
  terminate - but CICS should not terminate due to this
  Transient Data / Lock Manager issue.
  
  If a transaction is force purged while suspended for the TD
  lock then CICS should terminate the transaction with abend code
  ATDC, and leave TD control blocks in a consistent state.

Problem conclusion

• CICS has been modified so that FORCEPURGE of a transaction
  which is in Transient Data processing will not cause
  control to be passed back to the application with EIBRESP(ERROR)
  and Transient Data in a consistent state.
  Instead, the transaction will terminate with abend code ATDC.
  
  The explanation in IBM Publications for abend code ATDC
  will be changed to say:
  A transaction has issued an EXEC CICS READQ, WRITEQ or DELETEQ
  command against a transient data queue.
  The task was suspended, waiting for a resource.
  While suspended, the task was purged.
