Your problem is that you misunderstand the purpose of the servlet. It’s intented to act on HTTP requests, nothing more. You want just a background task which runs once on daily basis. EJB available? Use @Schedule If your environment happen to support EJB (i.e. a real Java EE server such as WildFly, JBoss, TomEE, Payara, … Read more
Use the Invoke-WebRequest cmdlet from Powershell. In your task: Action: Start a program Program/script: powershell.exe Arguments: -Command “Invoke-WebRequest http://myapp/BackgroundTask/Run”
I found the solution from the second comment you provided, Trengot, thanks. It turns out that I had some dangling blobs, which were in .git/objects/17 and hence triggering the packing: $ git fsck dangling blob d9ff0aeac4aa8b4e0907daed675ebf60278bc977 dangling blob dbff2d073741f9775c815d4a3c623736af224dad dangling blob e1ffbab1c5b985cd1cd3bc0281075ea2ed80744a dangling blob fdff59878ccb3a75689f4acca615cfb635288774 This cleaned them up: $ git gc –prune=now Be aware, … Read more
If you want something lightweight, that runs in the same process as the server, I highly recommend Bull. It has a simple API that allows for a fine grained control over your queues. If you’re looking for something that runs as a standalone worker process, perhaps look into Kue. It can run as a RESTful … Read more
You can use the start command to run a process in the background of the command window. command1 command2 start command3 command4 command2 waits until command1 finish but command4 don’t wait that command3 finishes. and if you need to run independently of the user logged on, you need to start the process as a service … Read more
After starting a process, you can send it SIGSTOP to suspend it. To resume it, send SIGCONT. I think that this little script may help you #!/bin/bash $@ & PID=$! kill -STOP $PID echo $PID wait $PID It runs process (command send as parameter), suspends it, prints process id and wait until it ends.
I found a solution to implement this with the help of the Apple Developer Forums: Specify location background mode Create an NSTimer in the background with UIApplication:beginBackgroundTaskWithExpirationHandler: When n is smaller than UIApplication:backgroundTimeRemaining it will work just fine. When n is larger, the location manager should be enabled (and disabled) again before there is no … Read more
If you’re using BASH, just press CTRL–Z, which will suspend the process, and then use the bg command to send it to the background. If you want more detail have a look at this article on BASH job control.
Check out the “nohup” program.
You could try writing to it’s /proc pid directory. Say your daemons’ pid is 2000, try writing to /proc/2000/fd/0
