Tuning the Sun Cluster HA for Sun Grid Engine Fault Monitors

The Sun Cluster HA for Sun Grid Engine fault monitors verify that the following daemons are running correctly:

• Communications daemon sge_commd

• Queue master daemon sge_qmaster

• Scheduling daemon sge_schedd

Each Sun Cluster HA for Sun Grid Engine fault monitor is contained in the resource that represents Sun Grid Engine component. You create these resources when you register and configure Sun Cluster HA for Sun Grid Engine. For more information, see Registering and Configuring Sun Cluster HA for Sun Grid Engine.

System properties and extension properties of these resources control the behavior of the fault monitor. The default values of these properties determine the preset behavior of the fault monitor. The preset behavior should be suitable for most Sun Cluster installations. Therefore, you should tune the Sun Cluster HA for Sun Grid Engine fault monitor only if you need to modify this preset behavior.

Tuning the Sun Cluster HA for Sun Grid Engine fault monitors involves the following tasks:

• Setting the interval between fault monitor probes

• Setting the timeout for fault monitor probes

• Defining the criteria for persistent faults

• Specifying the failover behavior of a resource
