How to Prepare the Nodes for a Multi-Instance Configuration

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

The procedure assumes two nodes in the cluster and implements the configuration shown in Figure 1–3.

Before You Begin

Ensure that the /etc/netmasks file has IP-address subnet and netmask entries for all logical hostnames. If necessary, edit the /etc/netmasks file to add any missing entries.

1. Create a failover resource group to hold the logical hostname and the 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.
