Executing program in parallel

Former Member — Mon, 02 Jun 2008 15:18:18 GMT

Hi, I want execute a program with SUBMIT statement, but i need execute it for example 6 times at the same time. The 6 processes must run in parallel.

How can i do it?

SUBMIT will keep your process busy until the called program is finished. For parallel processing you would need to look at asynchronous RFC.

You can create a JOB and than submit your program with that job.

Use FM JOB_OPEN, SUBMIT.. using JOBNUMBER , FM JOB_CLOSE to schedule your job and run the programs in parallel.

Hi Naimesh, can you show me an example code?

Idea is:

You need to call the JOB_OPEN ... JOB_CLOSE FMs inside the Loop, which can get you multiple jobs at a time.

The execution of the jobs will be based on the avaliable JOB PROCESSes.

Have a look at the attached code:



DATA: W_COUNT LIKE TBTCJOB-JOBCOUNT,
      W_CLASS LIKE TBTCJOB-JOBCLASS.
DATA: W_UNAME LIKE TBTCJOB-AUTHCKNAM.

PARAMETERS:  W_NAME  LIKE TBTCJOB-JOBNAME DEFAULT 'PARALLEL'.
* the selection parameters which you need to pass to FM
PARAMETERS: FLD1 TYPE CHAR10.



START-OF-SELECTION.

  W_CLASS = 'A'.

  CALL FUNCTION 'JOB_OPEN'
    EXPORTING
*     DELANFREP              = ' '
      JOBGROUP               = 'TEST'
      JOBNAME                = W_NAME
*     SDLSTRTDT              = NO_DATE
*     SDLSTRTTM              = NO_TIME
*      JOBCLASS               = w_class
    IMPORTING
      JOBCOUNT               = W_COUNT
*   CHANGING
*     RET                    =
*   EXCEPTIONS
*     CANT_CREATE_JOB        = 1
*     INVALID_JOB_DATA       = 2
*     JOBNAME_MISSING        = 3
*     OTHERS                 = 4
            .
  IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
  ENDIF.

* Submit program via jobname and jobcount
  SUBMIT ZTEST_NP1 WITH P_CHAR = FLD1            
                   VIA JOB W_NAME NUMBER W_COUNT
                    AND RETURN.
