The Sun Cluster HA for SWIFTAlliance Gateway fault monitor detects the following faults:

• Failure of a node

• Failure of a network connection

• Failure of a disk connection

• Failure of the SWIFTAlliance Gateway application to start on a node.

The Sun Cluster HA for SWIFTAlliance Gateway fault monitor does not detect software failures.

The Sun Cluster HA for SWIFTAlliance Gateway fault monitor is contained in the resource that represents SWIFTAlliance Gateway. You create this resource when you register and configure Sun Cluster HA for SWIFTAlliance Gateway. For more information, see SUNW.gds(1).

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 Sun Cluster installations. Therefore, tune the Sun Cluster HA for SWIFTAlliance Gateway fault monitor only if you need to modify this behavior.

Tuning the Sun Cluster HA for SWIFTAlliance Gateway 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 Sun Cluster HA for SWIFTAlliance Gateway. For more information, see the following sections:
