PI99329: WEB SERVICE REQUEST GETS MESSAGE DFHRZ0205 18/08/24 PTF PECHANGE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A Web Service request gets message DFHRZ0205 although
  DSRTPGM(NONE) was specified.
  
  The trace shows that RZRT2 is trying to load a program "NONE"
  which is resulting in a program not loadable exception.
  
  The reason why DFHRZ0205 is being issued is because RC
  DFHRZRTRDAT (DFHDYPDS) has been received with a DYRFUNC of 6.
  By the time that the router gets called, DYRFUNC got changed
  to a 5. It appears that it wasn't checked if a DSRTPGM
  program was specified or not.
  

Local fix

• Not available.

  * PROBLEM DESCRIPTION: DFHRZ0205 issued when a Web Service     *
  *                      transaction is defined DYNAMIC(YES)     *
  *                      but DSRTPGM=NONE is coded in the        *

  ****************************************************************
  A CICS region acting as a web service provider.
  A handler program in the PIPELINE has caused a context switch
  to occur.
  A new task was created and joined to the original task using
  request streams.
  The new task, transaction ID was defined, DYNAMIC(YES) and
  REMOTESYSTEM(XXXX).
  The Distributed Routing Program was called with DYRFUNC 0 (Route
  Select), DYROPTER was set to Y (re-invoke the router).
  The Distributed Routing Program was called again with DYRFUNC 6
  (The transaction has been routed to the target).
  DYROPTER was set to Y (re-invoke the router) by the router
  program.
  The transaction gets routed to remotesystem XXXX including
  DFHRZRTRDAT (DFHDYPDS) with a DYRFUNC of 6.
  .
  In the remote region, XXXX, the DFHSIT parameter DSRTPGM=NONE
  was specified.
  A requeststream task was started. During task start up
  DFHRZTCX BIND_XM_CLIENT was called.
  DYRFUNC was changed to 5 (Transaction is starting in the
  target region) before calling the Distributed Routing Program.
  The call to the Distributed Routing Program failed with
  DFHRZ0205, 'The call to invoke the Distributed Routing Program,
  NONE, has failed. The program was not loadable.'
  

Problem conclusion

• UI55629 UI55630 UI53949 UI53950
  DFHRZRTX has been modified so the distributed routing program
  is not called for route_initiate or route_terminate when
  DSRTPGM=NONE is specified in the SIT.
