Follow the instructions in the Sun Java System Application Server Installation and Administration Guide.
The Sun Java System Application Server can be installed on the local file system or on the global file system.
When creating the domains, you must create the domain directory in the global file system.
The extension property Domaindir for the SUNW.jsas resource type specifies the path to the domain directory. See SUNW.jsas Extension Properties.
When creating the Node Agents, you must create the Node Agents directory in the global file system.
After creating the domain, change all the DAS listener addresses to a failover IP address.
In the server-config entry in the file domain.xml, change the DAS HTTP, HTTPS, IIOP, and all other listener addresses to the failover IP address that you intend to use in the Sun Cluster DAS resource.
Before you modify the file domain.xml, remember to stop all the instances of DAS and Node Agents.
Configure the failover logical host names on which the server instances and Node Agents listen.
When the Node Agents and Sun Java System Application Server instances are created, the physical node addresses are set by default in the file domain.xml. Therefore, you must change the physical addresses to the failover logical host names that you plan to use for the Node Agents.
The file nodeagent.properties in the Node Agent configuration directory contains the entry agent.client.host=hostname, where hostname specifies the Sun Cluster node on which Node-Agent-name is configured to run, and where Node-Agent-name is the name of a particular Node Agent.
