Each data service that is supplied with the Oracle Solaris Cluster product has a built-in fault monitor. The fault monitor performs the following functions:
Detecting the unexpected termination of processes for the data service server
Checking the health of the data service
The fault monitor is contained in the resource that represents the application for which the data service was written. You create this resource when you register and configure the data service. For more information, see the documentation for the data service.
System properties and extension properties of this resource 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 Oracle Solaris Cluster installations. Therefore, you should tune a fault monitor only if you need to modify this preset behavior.
Tuning a fault monitor 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
Perform these tasks when you register and configure the data service. For more information, see the documentation for the data service.
