You can use the wsadmin tool to create application server,
generic server, web server, and proxy server clusters without cluster
members.
Before you begin
There are multiple ways to complete this task. This topic
uses the AdminConfig or AdminTask objects to create clusters without
cluster members in your environment. Alternatively, you can use the
createClusterWithoutMember script in the AdminClusterManagement script
library to create and configure clusters.
About this task
Perform the following steps to create a cluster without a
cluster member:
Procedure
- Start the wsadmin scripting tool.
- There are two ways to perform this task. Choose one of
the following:
- Using the AdminTask object:
Using Jacl:
$AdminTask createCluster {-interactive}
Using Jython:
AdminTask.createCluster (['-interactive'])
- Using the AdminConfig object:
- Identify the cell configuration ID and set it to the s1 variable:
Using Jacl:
set s1 [$AdminConfig getid /Cell:mycell/]
Using Jython:
s1 = AdminConfig.getid('/Cell:mycell/')
- Create a new cluster without a cluster member:
Using Jacl:
$AdminConfig create ServerCluster $s1 {{name ClusterName}}
Using Jython:
print AdminConfig.create('ServerCluster', s1, '[[name ClusterName]]')
- Save the configuration changes.
Use the following command example to save your configuration
changes:
AdminConfig.save()
- In a network deployment environment only, synchronize the
node.
Use the syncActiveNodes script in the AdminNodeManagement
script library to propagate the changes to all active nodes, as the
following example demonstrates:
AdminNodeManagement.syncActiveNodes()
