Hi Nate,
Ya I have seen the function __check_jobs_at_startup(), it calls the recover function after checking the state of the job from the database and updating the jobWrapper. But what it does after calling the recover function and one more thing, does it use the monitor() and the check_watched_item() in the drmaa.py.
Yes, notice that the last function of the recover() method is to insert the job state object into the DRM monitor queue with: self.monitor_queue.put( drm_job_state ) Which is the same as the final step of the submission process, the queue_job() method. Once this happens, the monitor thread will pick up the job state from monitor_queue (a Python Queue instance) and monitor it with monitor()/check_watched_items(). --nate
Thanks Harendra

Hi Nate,
I got your point but which part of the code is doing all these things, I mean how exactly this is done. Is it using any other function apart from recover?
Yes, see __check_jobs_at_startup() in lib/galaxy/jobs/__init__.py

Hi everyone,

But I am not ale to understand the flow of that function.
The recover function is called when the galaxy server is restarted. It first looks for the running jobs from the database. Then my problem is how it regains the same old state of the galaxy (specially the GUI) which was before the galaxy got restarted. Can anyone explain me the flow of the recover function and how the

Hi Harendra,
I'm not sure I understand what you mean by old state and the GUI - all that's really necessary here is to determine what Galaxy considers to be the state of the job (new, queued, running), recreate the in-memory job components (the JobWrapper), and place the job back in Galaxy's DRM-monitoring queue, which will then proceed with the process of finishing the job if it's finished in the DRM or waiting for it to finish if it's still queued or running in the DRM.
