Standard Data Service Configurations

Use the standard configurations in this section to plan the installation and configuration of Sun Cluster HA for BEA WebLogic Server. Sun Cluster HA for BEA WebLogic Server supports the standard configurations in this section.

In addition to the standard configurations provided in this section, the following BEA WebLogic Server configurations are possible.


Note –

The BEA WebLogic Server is currently supported as a Failover data service.


Sun Cluster HA for BEA WebLogic Server might support additional configurations. However, you must contact your Sun service provider for information on additional configurations.

Simple Configuration

This simple configuration for Sun Cluster HA for BEA WebLogic Server uses two resource groups configured as follows.

RG1 and RG2 are failover resource groups

This configuration is possible only if the BEA WebLogic Server is installed on a Global File System. See Figure 1 for an illustration of this configuration.

Figure 1 Sun Cluster HA for BEA WebLogic Server Simple Configuration

Illustration: The preceding context describes the graphic.

Configuration 1

In this configuration RG1, RG2, RG3, and RG4 are failover Resource Groups configured as follows.

This configuration is possible only if the BEA WebLogic Server is installed on a Global File System.

Configuration 2

In this configuration, RG1, RG2, and RG3 are failover Resource Groups configured as follows.

This configuration is possible only if the BEA WebLogic Server is installed on a Global File System.

Configuration 3

If the BEA WebLogic Server is installed on a Failover File system using HAStoragePlus, all the BEA WebLogic Server instances must be configured in the same Failover resource group which has a dependency on the Failover filesystem.

RG1 contains logical-host-resource resources and all Administration and Managed-Server resources.

For information on how to register a resource with dependency on an HAStoragePlus resource, see Enabling Highly Available Local File Systems in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

See Figure 2 for an illustration of this configuration.
