Sun Java Enterprise System 2005Q4 Installation Guide for UNIX

Sun Cluster Data Services Configuration

After the cluster has been established and the components have been configured, you are ready to configure Sun Cluster data services for the various Java ES components. The installed Sun Cluster agents are software programs that enable applications to take advantage of clusters. Agent software and additional configuration files comprise data services that enable you to run an application (such as Web Server or an Oracle database) on a cluster instead of on a single server. Combined with the Sun Cluster framework software and multihost disks, data services enable applications to become highly available and scalable.

Note –

You can deploy Access Manager and Portal Server in a highly available web container. However, they, like any web application deployed in a web container, are subject to failure. In this case, the web container will not fail over.

More information on data services can be found in the Sun Cluster Overview for Solaris OS.

The following sections list the Java ES components whose agents are provided in the Sun Cluster Agents component of the installer. For each component, the high availability service and the installation process are summarized, including the documentation needed. In any data service installation procedure referred to by the documentation, substitute the Java ES Sun Cluster Agents 3.1 8.05 Accessory CD-ROM.

Note –

Until you have fully configured the data services and all the supporting layers (volume manager, cluster file system, resource group information), Sun Cluster installation for Java ES is not complete.

Administration Server Data Service

Administration Server can be configured for failover. Refer to Sun Cluster Data Services Planning and Administration Guide for Solaris OS for information on installing and configuring the Administration Server data service.

To install the necessary packages, run the Java ES installer on each node, installing the Administration Server and HA Sun Java System Directory Server subcomponent of the Sun Cluster Agents for Sun Java System component. Select the Configure Later option.

During configuration, use a location on the cluster file system as the Server Root.

Application Server Data Service

Application Server can be configured for failover. Use Chapter 1, Sun Cluster HA for Sun Java System Application Server EE (Supporting HADB Versions as of 4.4), in Sun Cluster Data Service for Sun Java System Application Server EE (HADB) Guide for Solaris OS as a guide to installation and configuration.

To install the necessary packages, run the Java ES installer on each node, installing Application Serverand the HA Sun Java System Application Server(PE/SE) subcomponent of the Sun Cluster Agents for Sun Java System components. Select the Configure Later option.

When specifying installation directories, use the location on the node's local file system for Application Server, and use locations on the cluster file system for AS Configuration and Product Location.

Application Server EE (HADB) Data Service

The Application ServerHADB can be mastered for multiple nodes. Use Sun Cluster Data Service for Sun Java System Application Server EE (HADB) Guide for Solaris OS as a guide to installation and configuration.

To install the necessary packages, run the Java ES installer on each node, installing the HA Sun Java System HADB subcomponent of the Sun Cluster Agents component. Select the Configure Later option. When the database is created, the configuration and data files are created by default on the local file system of each cluster node. Store static files and data on the local file system of each cluster node.

Calendar Server Data Service

Calendar Server can be configured for failover. See Chapter 7, Configuring for High Availability (Failover Service), in Sun Java System Calendar Server 6 2005Q4 Administration Guide as a guide to installation and configuration.

To install the necessary packages:

Directory Server Data Service

Directory Server can be configured for failover. To install the necessary packages, run the Java ES installer on each node, installing Directory Server and the HA Sun Java System Directory Server subcomponent of the Sun Cluster Agents component. Select the Configure Later option.

When specifying installation directories, use a location on the cluster file system for Directory Server, Server Root.

Instant Messaging Data Service

Instant Messaging can be configured for failover. Refer to theSun Java System Instant Messaging 7 2005Q1 Administration Guide for instructions on configuring high availability for Instant Messaging.

Message Queue Data Service

Message Queue can be configured for failover. Use Sun Cluster Data Service for Sun Java System Message Queue Guide for Solaris OS as a guide to installation and configuration.

To install the necessary packages, run the Java ES installer on each node, installing Message Queue and the HA Sun Java System Message Queue subcomponent of the Sun Cluster Agents component. Select the Configure Later option.

During configuration, use a location on each node’s local file system for static files and data, and use a location on the cluster file system for dynamic data.

Messaging Server Data Service

Messaging Server can be configured for failover. Use Chapter 3, Configuring High Availability, in Sun Java System Messaging Server 6 2005Q4 Administration Guide as a guide to installation and configuration.

To install the necessary packages, run the Java ES installer on each node, installing Messaging Server and the HA Sun Java System Messaging Server subcomponent of the Sun Cluster Agents component. Select the Configure Later option.

When specifying installation directories, use a location on the cluster file system for Messaging Server. During configuration, place the configuration and data on the cluster file system.

Web Server Data Service

Web Server can be configured for failover or scalability. The following sections have information related to each option.

Web Server Data Service for Failover

Use Sun Cluster Data Service for Sun Java System Web Server Guide for Solaris OSSun Cluster Data Service for Sun Java System Web Server Guide for Solaris OS as a guide to installation and configuration.

To install the necessary packages:

Web Server Data Service for Scalability

Use Sun Cluster Data Service for Sun Java System Web Server Guide for Solaris OS as a guide to installation and configuration.

To install the necessary packages, run the Java ES installer on each node, installing Web Server and the HA/Scalable Sun Java System Web Server subcomponent of the Sun Cluster Agents component. Select the Configure Later option.

Data Services for Other Products

If your installation plan calls for high availability of some other product, acquire the agent that supports the product, then install and configure the agent following the instructions in the appropriate Sun Cluster data service guide. One way to get agents for other products is from the Java ES accessory CD.
