PH56710: DFHJSON-DATA CONTAINER NOT DELETED BY CICS IF IT EXISTS PRIOR TO EXEC CICS TRANSFORM JSONTODATA API CALL.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• While running CICS/TS 5.5 on z/OS 2.4 we noticed that CICS does
  not delete the DFHJSON-DATA container if it exists prior to a
  EXEC CICS TRANSFORM JSONTODATA API call.
  .
  The application program does not specify OUTCONTAINER.
  The dangers of not first deleting the DFHJSON-DATA container
  are that the DFHJSON-DATA container may contain the results
  from the previous EXEC CICS TRANSFORM !
  .
  Looking at the CICS trace, When the DFHJSON-DATA container
  exists, the
  AP E160 EXEC ENTRY TRANSFORM JSONTODATA trace shows
  INCONTAINER('DFHJSON-JSON ' AT X'A6745AF8')
  By the time it gets to the
  PI 3200 PIJS ENTRY - FUNCTION(TRANSFORM_JSON) trace,
  it shows REQUEST_NAME(DFHJSON-DATA) RESPONSE_NAME(DFHJSON-JSON)
  which is the wrong way around!
  

Local fix

• DELETE DFHJSON-DATA container in your application before
  issuing EXEC CICS TRANSFORM JSONTODATA.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS Users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: A program's consecutive TRANSFORM       *
  *                      JSONTODATA call fails.                  *
  ****************************************************************
  When an EXEC CICS TRANSFORM JSONTODATA API command is executed
  and the optional parameter OUTCONTAINER is not specified, CICS
  will put the output into the DFHJSON-DATA container.
  
  If this DFHJSON-DATA container is not deleted and a subsequent
  EXEC CICS TRANSFORM JSONTODATA API call not specifying
  OUTCONTAINER is made, CICS will incorrectly perform a data to
  JSON transformation which will likely fail or cause
  unpredictable results.
  

Problem conclusion

• DFHEIML has been changed to ensure that a residual DFHJSON-DATA
  container is deleted before the processing of an EXEC CICS
  TRANSFORM JSONTODATA command occurs.
