PH67347: DFH$XSR DOES NOT DETECT FAILING EXECIO COMMANDS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The DFH$XSR REXX exec does not check the return codes after
  issuing EXECIO commands. As a result, it is unaware of any
  failures that occur during input or output, and it is not
  prepared to handle these failures.

  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: DFH$XSR does not handle failing EXECIO  *
  *                      calls and so may report that the job    *
  *                      has run successfully even if it has     *
  *                      failed.                                 *
  ****************************************************************
  The DFHSM2R JCL is run to create RACF commands from security
  metadata. This invokes DFH$XSR which will not identify if any
  EXECIO call fails. This means that DFH$XR runs successfully even
  if reads or writes fail. In these scenarios you will see the
  following error within the job log along with a more specific
  cause of failure:
  
  IRX0670E EXECIO error while trying to GET or PUT a record.
  
  The job will then continue incorrectly and can result in an RC
  0000 which implies there were no issues.
  

Problem conclusion

• DFH$XSR has been updated to check the response of EXECIO calls
  and exit if a bad response was received, to give a defined
  failure.
