Create clusters
Use wsadmin.sh to create application server, generic server, and proxy server clusters. A cluster is a set of servers that you manage together as a way to balance workload.
There are multiple ways to complete this task. This topic uses the AdminConfig object to create clusters in the environment. Alternatively, we can use the ClusterConfigCommands command group for the AdminTask object or the createCluster script in the AdminClusterManagement script library to create and configure clusters.
- Start the wsadmin scripting tool.
- Identify the server to convert to a cluster.
Determine the configuration ID of the server of interest and assign it to the server variable:
- Jacl:
set server [$AdminConfig getid /Cell:mycell/Node:mynode/Server:server1/]
- Jython:
server = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:server1/')
- Convert the existing server to a cluster.
Use the convertToCluster command for the AdminConfig object to convert the existing server to a cluster. Specify the name of the server and the name to assign to the cluster.
- Jacl:
$AdminConfig convertToCluster $server myCluster1
- Jython:
AdminConfig.convertToCluster(server, 'myCluster1')
Example output:
myCluster1(cells/mycell/cluster/myCluster1|cluster.xml#ClusterMember_1)
- Save the configuration changes.
Use the following command example to save the 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:
AdminNodeManagement.syncActiveNodes()
