OIM Scheduler

This has been posted a couple times in other blogs, but it bears repeating. This is a tool that you can use to stop the scheduler (and a task) without having to stop the entire application

You can use the system admin account and password to start and stop the service.

IF you have a task that is in process and you want to stop that task immediately, use the scheduler. In the design console, for that task make sure the check box for "Stop Execution" is checked, save the task, then stop and start the scheduler. If this is not checked, the task will continue to run to completion.
