Tuning the HA for Oracle Database Fault Monitors

Language:

Fault monitoring for the HA for Oracle Database data service is provided by the following fault monitors:

The Oracle Database server fault monitor
The Oracle Database listener fault monitor

Note - If you are using an Oracle Grid Infrastructure for Clusters Single Client Access Name (SCAN) listener, no fault monitoring is provided for the SCAN listener by Oracle Solaris Cluster software.

Each fault monitor is contained in a resource whose resource type is shown in the following table.

Table 1-3 Resource Types for HA for Oracle Database Fault Monitors

Fault Monitor	Resource Type
Oracle Database server	`SUNW.oracle_server`
Oracle Database listener	`SUNW.oracle_listener`

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

Tuning the HA for Oracle Database 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
