.net 4.5, asp.net mvc: What is the best way to run long-lasting process (1-2 minutes) from ASP.NET application giving it should be run in a single-threaded environment, I mean the process is initiated for one user at a time only, executions for all other users have to wait till the current execution is done? The scenario is the following: user clicks button that run some sort of long-lasting calculations, http response returned to the user immediately, then user has to request status of the calculations with separate request manually. Asp.net http session abortion should not lead to the

I need to run a process that might take hours to complete from a Django view. I don't need to know the state or communicate with it but I need that view to redirect away right after starting the process. I've tried using subprocess.Popen , using it within a new threading.Thread , multiprocessing.Process . However, the parent process keeps hanging until child terminates. The only way that almost gets it done is using a fork. Obviously that isn't good as it leaves a zombie process behind until parent terminates. That's what I'm trying to do when using fork: if os.fork() == 0: subprocess.Popen(["

I want to execute a stored proc by clicking on a button developed in JSF and Java. The proc takes roughly around 30 minutes in execution. When the user clicks on this button, s/he should get a default message like - Data is being processed. Kindly login after 60 minutes to check the data. Now when we click on the button, the UI Page hangs for the time when the proc is getting executed. Is there a workaround to show this default message and run the proc in the backend? Just trigger an @Asynchronous EJB method. It'll fire and forget a separate thread and the bean action method will immediately

I have an application A that I would like to be able to invoke arbitrary other processes as specified by a user in a configuration file. Batch script B is one such process a user would like to be invoked by A. B sets up some environment variables, shows some messages and invokes a compiler C to do some work. Does Windows provide a standard way for arbitrary processes to be terminated cleanly? Suppose A is run in a console and receives a CTRL+C. Can it pass this on to B and C? Suppose A runs in a window and the user tries to close the window, can it cancel B and C? TerminateProcess is an option

We are implementing a REST API, which will kick off multiple long running backend tasks. I have been reading the RESTful Web Services Cookbook and the recommendation is to return HTTP 202 / Accepted with a Content-Location header pointing to the task being processed. (e.g. http://www.example.org/orders/tasks/1234 ), and have the client poll this URI for an update on the long running task. The idea is to have the REST API immediately post a message to a queue, with a background worker role picking up the message from the queue and spinning up multiple backend tasks, also using queues. The
