Monitoring of the Abnormal Exit of the Server Process

The Process Monitor Facility (PMF) monitors the data service processes.

The data service fault probe runs in an infinite loop and sleeps for an adjustable amount of time that the resource property Thorough_probe_interval sets. While sleeping, the probe checks with the PMF to see if the process has exited. If the process has exited, the probe updates the status of the data service as “Service daemon not running” and takes action. The action can involve restarting the data service locally or failing over the data service to a secondary cluster node. To decide whether to restart or to fail over the data service, the probe checks the value set in the resource properties Retry_count and Retry_interval for the data service application resource.
