PH12179: ABENDAEXZ ON EXEC CICS WRITE HTTPHEADER CALL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Your user application issues EXEC CICS WEB WRITE HTTPHEADER
  which results in an ABENDAEXZ.  While processing this command,
  CICS code issues EXEC CICS WRITEQ TS commands.  The ABENDAEXZ is
  the result of making EXEC CICS calls within an EXEC CICS call.
  Looking at the dump, the eiei_response has been overlaid.
  

Local fix

• correct the DFHEIWB trace entry points
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *

  * PROBLEM DESCRIPTION: Abend AEXZ on EXEC CICS WEB WRITE       *
  *                      HTTPHEADER.                             *
  ****************************************************************
  A task issues an EXEC CICS WEB WRITE HTTPHEADER. During
  execution of this command, CICS issues EXEC CICS WRITEQ TS
  commands to Temporary Storage. The eiei parameter list for exec
  calls is reused and overwritten.
  When control is passed back with the response to the WRITE
  HTTPHEADER call, the response is no longer valid which causes an
  abendAEXZ (Command failed due to serious error in CICS
  component). The fix of PQ93846 is required at this release.
  Depending on the overlay, another unexpected response to the
  EXEC CICS WEB WRITE HTTPHEADER may be seen.
  Instead of EIWB trace points being seen in AP 1-2 trace, they
  are written as JCRM trace points.
  Keywords: DFHWB0125 msgDFHWB0125 DFHWB0101 msgDFHWB0101
  

Problem conclusion

• DFHEIWB has been changed so the eiei parameter list is saved
  before the DFHWBAPM WRITE_HEADER call and restored afterwards.
  EIWB trace points are written correctly.
  

Temporary fix
