RE: parallel processes and thread.sleep

Hello Vlada,

I have tested according to what you suggested to start a new thread for each
process instance. However the results show they are still running in
sequence based on the sequence to run them, but not in parallel. Could you
please kindly advice further? Thank you very much.
(pl. my process contains only automatic activities.)
Best Regards,
He Wei

Since Shark does not start a new thread, your application must, for 
scenario you described.

       //final SharkConnection sc;
       //final Map workflowRelevantData;
       for (int i = 0; i < 5; i++) {
          new Thread() {
             public void run() {
                try {
                   WfProcess theProcess = sc.createProcess("pkg","pdef");
                   theProcess.set_process_context(workflowRelevantData);
                   theProcess.start();
                } catch (RootException e) {
                   e.printStackTrace();
                }
             }
          }.start();
       }
