How to submit / launch a concurrent request set from backend

submit concurrent request set from backend

I always had a doubt as how to call a concurrent request set from backend. I got this useful material while googling. So taught of sharing with you ppl. Hope you will enjoy.

When programmatically launching a request set, base it on the following skeleton code. Couple of points to note first:

1. When a concurrent program has parameters, you must pass a value (or null) for each parameter that is on the Concurrent Program Definition - it is NOT the parameters that you see in the Request Set Definition as ones that are not displayed cannot be seen there, but programmatically are required.
2. Default values that are set up in the concurrent program definition, or the request set definition are not calculated for you - you must pass them in programmatically.
3. ALL stages of the request set must be programmatically dealt with - failure to do so will prevent the request set from running and you will not see ANY of it (the request set is effectively rolled back).
4. The values of the parameters that you pass must correspond to the values seen in the Parameters field in the Requests Windows, when you manually launch the job.
