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.
Separate START script for each BEA WebLogic Server (Administration and Managed).
Single START script for all Managed Servers which takes the Managed Server name as the input.
Setting the username and password in boot.properties.
This configuration allows only forced shutdown by Sun Cluster HA for BEA WebLogic Server.
Setting the username and password in the START script.
This configuration allows smooth shutdown by Sun Cluster HA for BEA WebLogic Server.
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.
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.
In this configuration RG1, RG2, RG3, and RG4 are failover Resource Groups configured as follows.
RG1 containing logical-host-1 and WLS-Admin-resource
RG2 containing logical-host-2 and WLS-Managed-Server-resource2
RG3 containing logical-host-3 and WLS-Managed-Server-resource3
RG4 containing logical-host-4 and WLS-Managed-Server-resource4
This configuration is possible only if the BEA WebLogic Server is installed on a Global File System.
In this configuration, RG1, RG2, and RG3 are failover Resource Groups configured as follows.
RG1 containing logical-host-1, WLS-Admin-resource, and WLS-Managed-Server-resource1
RG2 containing logical-host-2, WLS-Managed-Server-resource2, WLS-Managed-Server-resource3, and WLS-Managed-Server-resource4
RG3 containing logical-host-3, WLS-Managed-Server-resource5, WLS-Managed-Server-resource6, WLS-Managed-Server-resource7
This configuration is possible only if the BEA WebLogic Server is installed on a Global File System.
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 3.1 Data Service Planning and Administration Guide.
See Figure 1–2 for an illustration of this configuration.
