PH52991: The dynamic routing program is redriven after a task has been PURGED.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When an EXEC CICS LINK request is dynamically routed to a remote
  region over an IPIC connection, and the task issuing the DPL
  request is then the subject of a PURGE or FORCEPURGE, the
  dynamic routing program can be redriven in the originating
  region.
  
  This APAR will avoid the routing program being called a
  subsequent time in the originating region after a task has
  been purged.

  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: The dynamic routing program can be      *
  *                      called for a second time after a PURGE  *
  *                      or FORCEPURGE command has been          *
  *                      performed against a task that has       *
  *                      issued a DPL request to a remote region *
  *                      over an IPIC connection.                *
  ****************************************************************
  When a DPL request is routed to a remote region over an IPIC
  connection, the dynamic routing program can be called again
  after the task has been PURGED or FORCEPURGED.
  
  When a program that is defined as DYNAMIC(YES) is the target of
  a DPL request, the request can be routed to a remote region by
  the dynamic routing program specified on the DTRPGM SIT
  parameter.
  If a PURGE or FORCEPURGE is issued against the task in the
  originating region (the region that issued the DPL request), the
  dynamic routing program can be called again and the request may
  be routed to another region to run.
  

Problem conclusion

• DFHEPC has been changed so the the dynamic routing program is
  not called again in these cases. The task that has been purged
  will abend with new abend code AITQ.
  
  The CICS TS 5.6 "What's new?" section will be updated with the
  new abend code.
  
  The CICS TS 5.6 and CICS TS 6.1 documentation will be updated
  with the following:
  
  AITQ
  
  Explanation: The transaction was processing a request which
  involved waiting for a response from a connected subsystem over
  an IPIC connection. During the wait, the transaction was purged.
  
  SystemAction: The task is abnormally terminated.
  
  UserResponse: Investigate the reason the transaction was purged.
