How to Prepare the Nodes for a Failover Configuration

Use this procedure to prepare for the installation and configuration of Oracle WebLogic Server in a failover configuration.

1. Create a failover resource group to hold the logical hostname and the Oracle WebLogic Administration Server resources.

   # clresourcegroup create [-n nodelist] RG1

2. Add the logical hostname resource.

   The logical-host–1 is the hostname the Oracle WebLogic Administration Server will be listening on. This hostname can be set from the WebLogic console.

   # clreslogicalhostname create -g RG1 logical-host-1

   ---

   Note - If you require a fully qualified hostname, you must specify the fully qualified name with the -h option and you cannot use the fully qualified form in the resource name.

   ---

3. Bring the resource group online.

   # clresourcegroup online -M RG1

4. Create a failover resource group to hold the logical hostname and the WebLogic Managed Server resources.

   ---

   Note - Depending on the number of Oracle WebLogic Servers and on the configuration planned, create the resource groups and the logical_hostname resources. Refer to Standard Data Service Configurations.

   ---

   # clresourcegroup create [-n nodelist] RG2

5. Add the logical hostname resource.

   The logical-host-2 is the hostname on which the Oracle WebLogic Administration Server will be listening.

   # clreslogicalhostname create -g RG2 logical-host-2

   ---

   Note - If you require a fully qualified hostname, you must specify the fully qualified name with the -h option and you cannot use the fully qualified form in the resource name.

   ---

6. Bring the resource group online.

   # clresourcegroup online -M RG2

7. Create a highly-available local file system managed by the HAStoragePlus resource.

How to Prepare the Nodes for a Multi-Master Configuration

Use this procedure to prepare for the installation and configuration of Oracle WebLogic Server in a multi-instance configuration that uses single-node resource groups.

1. Create a failover resource group to hold the logical hostname and the Oracle WebLogic Administration Server resources.

   # clresourcegroup create [-n nodelist] RG1
   # clreslogicalhostname create -g RG1 logical-host-1
   # clresourcegroup online -M RG1

2. Create failover resource groups for the logical hostnames for the managed server.

   # clresourcegroup create -p nodelist=node1,node2 logicalhost-n1-rg
   # clresourcegroup create -p nodelist=node2,node1 logicalhost-n2-rg

3. Create logical hostname resources in the resource groups.

   # clreslogicalhostname create -g logicalhost-n1-rg -h logicalhost-n1 logicalhost-n1-rs
   # clreslogicalhostname create -g logicalhost-n2-rg -h logicalhost-n2 logicalhost-n2-rs

4. Bring the logical hostname resource groups online.

   # clresourcegroup online -emM logicalhost-n1-rg
   # clresourcegroup online -emM logicalhost-n2-rg

5. Create a cluster file system managed by the HAStoragePlus resource.

How to Prepare the Nodes for a Multi-Instance Configuration

Use this procedure to prepare for the installation and configuration of Oracle WebLogic Server in a multi-master configuration.

The procedure assumes two nodes in the cluster and implements the configuration shown in Figure 1-4.

1. Create a failover resource group to hold the logical hostname and the Oracle WebLogic Administration Server resources.

   # clresourcegroup create [-n nodelist] RG1
   # clreslogicalhostname create -g RG1 logical-host-1
   # clresourcegroup online -M RG1

2. Create failover resource groups for the logical hostnames for the managed server.

   # clresourcegroup create -p nodelist=node1,node2 logicalhost-n1-rg
   # clresourcegroup create -p nodelist=node2,node1 logicalhost-n2-rg

3. Create logical hostname resources in the resource groups.

   # clreslogicalhostname create -g logicalhost-n1-rg -h logicalhost-n1 logicalhost-n1-rs
   # clreslogicalhostname create -g logicalhost-n2-rg -h logicalhost-n2 logicalhost-n2-rs

4. Bring the logical hostname resource groups online.

   # clresourcegroup online -emM logicalhost-n1-rg
   # clresourcegroup online -emM logicalhost-n2-rg

5. Set the Failback property for each logical hostname resource group.

   # clresourcegroup set -p Failback=True logicalhost-n1-rg
   # clresourcegroup set -p Failback=True logicalhost-n2-rg

6. Create a cluster file system managed by the HAStoragePlus resource.
