    Both, SA and IWS (TWS) will be enhanced to support conditional
    dependencies for operations that are complete 'C'.
    
    SA will provide a new AAO called AOF_AAO_TWS_CHK_OUTPUT_NETLOG
    similar to the existing AAO AOF_AAO_TWS_CMD_OUTPUT_NETLOG for
    commands. If its value is YES, it will ensure that the output
    of the completion checking routine is written to the NETLOG in
    all cases and not only when the operation ended in error.
    

Problem conclusion

Temporary fix

Comments

  • The SA - IWS (TWS) interface has been enhanced to support
    conditional dependencies for operations that are complete 'C'.
    Based on the result of the command, customers can now implement
    different courses of action, regardless of whether the operation
    completed successfully or failed.
    
    When the installation wants to make use of conditional
    dependencies, it must change the return code processing of the
    completion checking routine such that any rc <= maxrc is not
    forced to 0 (as today) just to tell SA, that the operation
    completed successfully. Instead, the completion checking routine
    is expected to return the rc as is. The caller of the completion
    checking routine, EVJESCHK, will then perform the check:
    
    If rc = -2 then setup a timer to call completion checking
       routine after the maximum wait time;
    
    If rc <= maxrc then call OPCAPOST with TYPE = 'C' and
       RETCODE=nnnn;
    
    If rc > maxrc then call OPCAPOST with TYPE='E' and ERRCODE=Rnnn;
    
    nnnn / nnn is the rc with leading '0's.
    
    In summary:
    o When commands end with a return code <= maxrc (default = 0)
      the operation is considered complete and the return code is
      passed to IWS (TWS).
    o When commands end with a return code > maxrc the operation is
      considered in error and the error code is passed in format
      Rnnn to IWS/TWS (no change).
    o If used, completion checking routine is expected to provide
      return code > maxrc (instead of >0) in order to post the
      operation in error with error code Rnnn;
      - Only, when AOF_AAO_TWS_CHK_CONDDEP = 'YES';
      - Otherwise, SA still compares rc > 0.
    o If used, completion checking routine is expected to provide
      positive return code <= maxrc in order to post operation
      complete with return code 'nnnn';
      - Only, when when AOF_AAO_TWS_CHK_CONDDEP = 'YES';
      - Otherwise, SA still compares rc = 0.
    o OPCAPOST accepts ERRCODE-keyword parameter in combination with
      TYPE=C.
    o OPCACOMP accepts positional error_code parameter in
      combination with status C.
    o OPCAQRY shows operation details
      - Return code is shown for complete operations;
      - Error code + error message is shown for operations in error.
    
    IWS (TWS) provides the following enhancements with APAR PI47790
    for IWS 9.3:
    o IWS introduced new JTOPTS option USINRC(Y|N) to turn
      conditional dependency support ON or OFF on a global level.
      - USINRC(N) - no support of conditional dependencies
        (default).
      - USINRC(Y) - EQQUSIN and EQQUSINT allow to specify return
        code for complete operations.
    o IWS enhanced EQQUSINT
      - OPERR can be specified with TYPE='C'.
      - Callers are expected to initialize OPERR to '0000' to
        guarantee compatible behavior (all SA z/OS code driving this
        interface have been changed).
    o IWS enhanced EQQUSIN
      - ERROR_CODE can be specified with STATUS='C'.
      - Callers are expected to initialize ERROR_CODE to '0000' to
        guarantee compatible behavior (all SA z/OS code driving this
        interface have been changed).
    
    APAR PI47790 must be installed in order to exploit SA's new
    conditional dependencies support.
    Refer to the documentation in APAR PI47790 for further
    instructions how to enable the new function.
