Target object

Specifies the name of the dynamic cluster.

Required parameters

membershipPolicy: Specifies the membership policy.

Optional parameters

• -dynamicClusterProperties: Specifies the dynamic cluster properties. (String, optional) You can specify the following options:
  • operationalMode: Specifies the operational mode. The valid values are: manual, supervised, and automatic.
  • minInstances: Specifies the minimum number of cluster instances as an integer.
  • serverInactivityTime: Specifies the time to wait before stopping instances, in minutes. This value is valid only when the minInstances parameter value is set to 0.
  • maxInstances: Specifies the maximum number of cluster instances as an integer. If you do not want a limit to the number of cluster instances that can start, specify -1.
  • numVerticalInstances: Specifies the number of instances that can start on the same node by creating vertical instances. Specify an integer value.
• -clusterProperties: Specifies the cluster properties. (String, optional) You can specify the following options:
  • preferLocal: Specifies whether enterprise bean requests are routed to the node on which the client resides when possible. The valid values are true or false.
  • createDomain: Specifies that a replication domain is created for this cluster. Replication domains can be created only for WebSphere Application Server application servers. The valid values are true or false.
  • coreGroup: Specifies the name of the core group for the dynamic cluster. You only need to specify the core group for WebSphere Application Server application servers. The value can be DefaultCoreGroup or the core group name.
  • templateName: Specifies the name of the server template. The valid input includes the following values:
    • For WebSphere Application Server dynamic clusters: defaultXD, defaultXDZOS, cell_name/node_name/was_server_name
  • clusterShortName: For z/OS platforms, specifies the short name of the cluster. After the dynamic cluster has been created, you can use the AdminTask changeClusterShortName command to update this field.
  • serverSpecificShortNames: For z/OS platforms, specifies the specific short name of cluster member in a comma-separated list format, for example: SSN1,SSN2. Use commas to separate multiple short names. If you do not provide enough short names to be used for all of the cluster members, then the remaining cluster members are assigned generated generic short names, such as BBOS001, BBOS002, and so on. After the dynamic cluster has been created, you can update this list with the serverSpecificShortNames custom property. This property is set on the dynamic cluster. If you want to change this property with scripting after the dynamic cluster has been created, you can use the AdminTask changeServerSpecificShortName command.
