3. This screen is divided into two parts. The first part displays the status of the kernel and allows you to change the status as and when required. The second part displays a list of process flows that are running (if kernel is running).

4. To pause the Kernel, click Pause Kernel button on the Manage Kernel screen. A confirmation screen is displayed. Click OK to pause the Kernel. This pauses the Kernel and displays a screen with the message that the Kernel has been paused.

   The Pause Kernel button changes to Resume Kernel, once the Kernel is paused.
   When the Kernel is Paused, the list of running process flows is not displayed.

5. To resume the Kernel, click Resume Kernel button. This resumes the Kernel and displays the Change Kernel State screen. Once the Kernel is resumed, it starts accepting new process flow requests for execution. The Queue Processor also activates and escalates process flows in queue, and the Scheduler resumes triggering of events.
