ClusterConfigCommands command group for the AdminTask object

changeClusterShortName

The createCluster command changes the short name that is associated with the cluster.

Target object

Steps

-clusterName (required)

Specifies the name of the server cluster. (String)

-shortName (optional)

Specifies the new short name that you want to associate with the cluster. Every cluster must have a unique short name. If this parameter is not specified, a unique short name is automatically assigned. The value that you specify for this parameter must be 8 characters or less in length and all of the characters must be in uppercase.

Examples

Batch mode example usage:

• Using Jacl:

  $AdminTask changeClusterShortName {-clusterName cluster1 -shortName newshortname}

• Using Jython string:

  AdminTask.changeClusterShortName('[-clusterName mycluster -shortName newshortname]')

• Using Jython list:

  AdminTask.changeClusterShortName(['-clusterName', 'mycluster', '-shortName', 'newshortname'])

Interactive mode example usage:

• Using Jacl:

  $AdminTask changeClusterShortName {-interactive}

• Using Jython:

  AdminTask.changeClusterShortName ('-interactive')

• Using Jython list:

  AdminTask.changeClusterShortName (['-interactive'])

createCluster

The createCluster command creates a new server cluster. A server cluster consists of a group of servers that are referred to as cluster members. Optionally, a replication domain can be created for the new cluster, and an existing server can be included as the first cluster member. You can also use the createCluster command to apply proxy server settings to the cluster.

Target object

Steps

-clusterConfig (required)

Specifies the following configuration information for the new server cluster:

-clusterName

Specifies the name of the server cluster. (String)

-preferLocal

Optionally specifies whether to enable or disable node-scoped routing optimization within the cluster. The default value is false. Specify true to enable node-scoped routing optimization. (Boolean)

Supported configurations: If you enable the preferLocal optimization, the deployment manager must be running to affect the configuration. If the deployment manager is shut down, preferLocal optimization is not performed and requests might be dispersed across all the members of the cluster.

-clusterType

Optionally specifies the type of the server cluster to create. The default type is APPLICATION_SERVER. Valid values for this parameter include: APPLICATION_SERVER, PROXY_SERVER, and ONDEMAND_ROUTER. (String)

-shortName

Specifies the specific short name of the server. Each server should have a specific short name. The value of this parameter must be 8 uppercase characters or less. If you do not specify a value for the specificShortName parameter, the system generates a unique short name. (String)

-replicationDomain (optional)

The system uses the replication domain properties for HTTP session data replication.

-createDomain

Specifies whether to create a replication domain in your cluster configuration. The default value is false. Specify true to create a replication domain in your cluster configuration. (Boolean)

-convertServer (optional)

Specifies information about an existing application server to convert to be the first member of the cluster. This command step is optional. The following parameters can be specified for this step:

-serverNode

The name of the node with the server to be converted to the first cluster member. You must also specify the serverName parameter. (String)

-serverName

The name of the application server to be converted to the first cluster member. You must also specify the serverNode parameter. (String)

-memberWeight

The weight of the cluster member. The weight controls the amount of work directed to the application server. If the weight is greater than the weight assigned to other cluster members, the server will receive a larger share of the workload. The value is a number between 0 and 100. If none is specified, the default is 2. (Integer)

-nodeGroup

The name of the node group which this cluster member's node, and all future cluster members' nodes, must belong to. All cluster members must reside on nodes in the same node group. If specified, it must be one of the node groups which this member's node belongs to. If not specified, the default value will be the first node group listed for this member's node. (String)

-replicatorEntry

Specifies whether to enable HTTP session data replication. The default value is false. Specify true to enable HTTP session data replication. You must specify this parameter if the createDomain parameter was set to true in the replicationDomain command step. (String)

-resourcesScope

Specifies what to do with server resources after the server is moved into a cluster. Possible values:

• server: Specifies that server resources and cluster resources remain where they are, unchanged.
• cluster: Specifies that server resources are moved to the cluster level. The cluster scope resources are set from the resources in the server. The server scope resources are removed.
• both: Specifies that the server resources are copied to the cluster scope. The cluster scope resources are set from the resources in the server. The server scope resources remain unchanged.

The default value is cluster.

For transitioning users: The default value for the -resourcesScope parameter has been changed to cluster for Version 8.x. The default value is both in Version 7.

Examples

Batch mode example usage:

• Using Jacl:

  $AdminTask createCluster {-clusterConfig {-clusterName cluster1 -preferLocal true 
   -clusterType APPLICATION_SERVER}}

  $AdminTask createCluster {-clusterConfig {-clusterName cluster1 -preferLocal true 
   -clusterType APPLICATION_SERVER} -replicationDomain {-createDomain true}}

  $AdminTask createCluster {-clusterConfig {-clusterName cluster1 -preferLocal true 
   -clusterType APPLICATION_SERVER} -convertServer {-serverNode node1 -serverName server1}}

• Using Jython string:

  AdminTask.createCluster('[-clusterConfig [-clusterName cluster1 -preferLocal true 
   -clusterType APPLICATION_SERVER]]') 

  AdminTask.createCluster('[-clusterConfig [-clusterName cluster1 -preferLocal true 
   -clusterType APPLICATION_SERVER] -replicationDomain [-createDomain true]]') 

  AdminTask.createCluster('[-clusterConfig [-clusterName cluster1 -preferLocal true 
   -clusterType APPLICATION_SERVER] -convertServer [-serverNode node1 -serverName server1]]')

• Using Jython list:

  AdminTask.createCluster(['-clusterConfig', '[-clusterName cluster1 -preferLocal 
   true -clusterType APPLICATION_SERVER]']) 

  AdminTask.createCluster(['-clusterConfig', '[-clusterName cluster1 -preferLocal true
    -clusterType APPLICATION_SERVER]', '-replicationDomain', '[-createDomain true]'])

  AdminTask.createCluster(['-clusterConfig', '[-clusterName cluster1 -preferLocal 
   true -clusterType APPLICATION_SERVER]', '-convertServer', '[-serverNode node1 -serverName server1]'])

Interactive mode example usage:

• Using Jacl:

  $AdminTask createCluster {-interactive}

• Using Jython:

createClusterMember

The createClusterMember command creates a member of a server cluster. A cluster member is an application server that belongs to a cluster. If this is the first member of the cluster, you must specify a template to use as the model for the cluster member. The template can be either a default server template, or an existing application server.

The first cluster member is used as a template to create subsequent members in the cluster. When you create a first cluster member, the template of the cluster member is stored under the scope of the cluster.

Target object

coreGroup

Optionally specifies the name of the core group to which the new cluster member and each additional cluster member belongs. Each cluster members must belong to the same core group. If you do not specify this parameter, the system assigns the default core group in the cell. (String)
