Use the wsadmin tool to create cluster members in application
server, generic server, web server, and proxy server clusters.
Before you begin
There are multiple ways to complete this task. This topic
uses the AdminConfig object to create cluster members in your environment.
Alternatively, you can use the ClusterConfigCommands command group
for the AdminTask object or the createClusterMember script in the
AdminClusterManagement script library to create and configure clusters.
About this task
The template options are available only for the first
cluster member that you create. All cluster members that you create
after the first member will be identical. A template is stored in
the cluster scope that you must use to create additional cluster members.
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:
$AdminTask createClusterMember {-interactive}
Using Jython:
AdminTask.createClusterMember ('[-interactive]')
- Using the AdminConfig object:
- Identify the existing cluster and assign it to the cluster variable:
Using Jacl:
set cluster [$AdminConfig getid /ServerCluster:myCluster1/]
Using Jython:
cluster = AdminConfig.getid('/ServerCluster:myCluster1/')
print cluster
Example output:
myCluster1(cells/mycell/clusters/myCluster1|cluster.xml#ServerCluster_1)
- Identify the node to create the new server and assign it to the
node variable:
Using Jacl:
set node [$AdminConfig getid /Node:mynode/]
Using Jython:
node = AdminConfig.getid('/Node:mynode/')
print node
Example output:
mynode(cells/mycell/nodes/mynode|node.xml#Node_1)
- (Optional) Identify the cluster member template and assign it
to the serverTemplate variable:
Using Jacl:
set serverTemplate [$AdminConfig listTemplates Server]
Using Jython:
serverTemplate = AdminConfig.listTemplates('Server')
print serverTemplate
Example output:
server1(templates/default/nodes/servers/server1|server.xml#Server_1)
- Create the new cluster member, by using the createClusterMember command.
- The following example creates the new cluster member, passing
in the existing cluster configuration ID, existing node configuration
ID, and the new member attributes:
Using Jacl:
$AdminConfig createClusterMember $cluster $node {{memberName clusterMember1}}
Using Jython:
AdminConfig.createClusterMember(cluster, node, [['memberName', 'clusterMember1']])
- The following example creates the new cluster member with a template,
passing in the existing cluster configuration ID, existing node configuration
ID, the new member attributes, and the template ID:
Using Jacl:
$AdminConfig createClusterMember $cluster $node
{{memberName clusterMember1}} $serverTemplate
Using Jython:
print AdminConfig.createClusterMember(cluster, node,
[['memberName', 'clusterMember1']], serverTemplate)
Example output:
clusterMember1(cells/mycell/clusters/myCluster1|cluster.xml$ClusterMember_2)
- 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()
