This simple configuration for Sun Cluster HA for BEA WebLogic Server uses two resource groups configured as follows.
RG1 containing logical-host-1 and WLS-Admin-Server-resource
RG2 containing logical-host-2 and WLS-Managed-Server-resource
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 1–1 for an illustration of this configuration.
