The Sun Java System Application Server can be installed either on the global file system or on a local file system on all the Sun Cluster nodes. The directories for the Domain Administration Server and for the Node Agents must reside on the global file system.
Store static files and data on the local file system of each cluster node. Dynamic data must reside on the cluster file system.
The Domain Administration Server must be configured to listen on a failover IP address. Before you start your installation, determine the failover IP address that you plan to use for the DAS.
The instances and Node Agents must also be configured to listen on failover IP addresses, which are represented by logical host names. Before you start your installation, determine the failover logical host name that you plan to use for each Node Agent.
Do not use the Sun Java System Application Server administrative tools to start or stop the Sun Java System Application Server instances while application instances are running under Sun Cluster control.
The Sun Java System Application Server administration password is needed for some administration commands and actions. You must set this password in a file whose syntax is specified in the Sun Java System Application Server documentation. The path to this file must be specified with an extension property when you create the resources. See SUNW.jsas Extension Properties for a description of this extension property and the syntax of the password entry in the file.
The Sun Java System Application Server Domain Administration Server (DAS) must start without prompting the user for the master password. Therefore, set the savemasterpassword option to true when you create the DAS.
