How to Prepare the Nodes for a Failover Configuration
Use this procedure to prepare for the installation and configuration of WebLogic Server
in a failover configuration.
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.
-
Create a failover resource group to hold the logical hostname and the WebLogic
Administration Server resources.
# clresourcegroup create [-n nodelist] RG1
-
Add the logical host name resource.
The logical-host–1 is the host name where WebLogic
Administration Server will be listening. This host name can be set from the WebLogic
console.
# clreslogicalhostname create -g RG1 logical-host-1
Note -
If you require a fully qualified host name, you must specify the fully qualified name with the
-h option and you cannot use the fully qualified form in the resource
name.
-
Bring the resource group online.
# clresourcegroup online -M RG1
-
Create a failover resource group to hold the logical host name and the WebLogic
Managed Server resources.
Note -
Depending on the number of 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
-
Add the logical host name resource.
The logical-host-2 is the host name where the WebLogic
Managed Server will be listening.
# clreslogicalhostname create -g RG2 logical-host-2
Note -
If you require a fully qualified host name, you must specify the fully qualified name with the
-h option and you cannot use the fully qualified form in the resource
name.
-
Bring the resource group online.
# clresourcegroup online -M RG2
-
Create a highly-available local file system managed by the HAStoragePlus
resource.
