Wait for concurrent request using fnd_concurrent.wait_for_request

Most of the times while submitting concurrent request one has to wait for its completion to perform sequence of steps. This can be achieved through fnd_concurrent.wait_for_request in oracle apps. It returns the status of the previously submitted concurrent program upon interval set.

This is a conjunction to the SUBMIT_REQUEST. Follow ARTICLE on submitting concurrent program and use below call upon completed. There are some parameter that has to be declared.

      lb_complete      BOOLEAN;
      lc_phase           VARCHAR2 (100);
      lc_status           VARCHAR2 (100);
      lc_dev_phase   VARCHAR2 (100);
      lc_dev_status   VARCHAR2 (100);
      lc_message      VARCHAR2 (100);

ln_request_id is return variable for concurrent_request_id from above article. If ln_request_id > 0 (means request submitted successfully) then wait_for_request.

   Arguments (input)
     request_id    - Request ID to wait on
     interval         - time b/w checks. Number of seconds to sleep (default 60 seconds)
     max_wait      - Max amount of time to wait (in seconds) for request's completion
  Arguments (output)
                 User version of      phase and status
                 Developer version of phase and status
                 Completion text if any
     phase            - Request phase ( from meaning in fnd_lookups )
     status            - Request status( for display purposes          )
     dev_phase    - Request phase as a constant string so that it can be used for comparisons
     dev_status    - Request status as a constatnt string
     message       - Completion message if request has completed

      IF ln_request_id > 0
      THEN
         lb_complete :=
            fnd_concurrent.wait_for_request (request_id      => ln_request_id
                                                             ,interval            => 2
                                                             ,max_wait        => 60

                                                             -- out arguments
                                                             ,phase              => lc_phase
                                                             ,status              => lc_status
                                                             ,dev_phase      => lc_dev_phase
                                                             ,dev_status      => lc_dev_status
                                                             ,message         => lc_message
                                            );
         COMMIT;

         IF UPPER (lc_dev_phase) IN ('COMPLETE')
         THEN
            dbms_output.put_line('Concurrent request completed successfully');
         END IF;
      END IF;
