PH60673: ERROR FOUND IN THE DAISY CHAIN SUPPORT THAT WAS ADDED AT CICS TS 6.1

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When the dynamically routed request arrives in CICSB from CICSA
  and the request indicates that daisy chaining support is
  required the DYRUSERN field is saved so that it can be restored
  and passed on before calling the next region in the daisy chain.
  When the routing commarea is passed between regions , the
  pointer to the user area (held in field DYRUAPTR) is an offset
  from the start of the commarea. This is then received in the
  target region and converted into an address to be used to access
  the user area. In the case of daisy chaining, there is an issue
  in the code were this conversion is not not working as expected
  in the intermediate regions in the chain which results in an
  incorrect address being calculated for the user area.

  ****************************************************************
  When attempting to daisy chain non terminal related START
  requests using a customised version of the distributed routing
  program, abends can be seen when attempting to access or update
  the user area (DYRUSERN) in an intermediate region using
  DYRUAPTR. This is caused by an incorrect address being
  calculated for this field and being passed on to the routing
  program.

Problem conclusion

• DFHEIIC has been corrected so that the address of the user area
  is correctly calculated and passed on to the routing program in
  DYRUAPTR when daisy chaining non terminal related START
  requests.
