LogicalCluster

public LogicalCluster(ClusterFactory cf)
               throws JMException

logical cluster constructor

Parameters:

cf - ClusterFactory

Throws:

JMException - could not create MBean instance

Method Detail

createClusterMember

public ClusterMember createClusterMember(String svname,
                                         ServerProxy proxy)

Description copied from class: BaseCluster

Create a new ClusterMember. Depends on the underlaying class.

Specified by:

createClusterMember in class BaseCluster

getType

public String getType()

Specified by:

getType in class BaseCluster

Returns:

The String type to be put in the ObjectName

addServer

public boolean addServer(String serverName,
                         ServerProxy proxy)

Add a Server to the list. Make link between the member and the ServerProxy.

Parameters:

serverName - name of the managed server

proxy - The ServerProxy related object.

Returns:

True if correctly added in the List.

removeServer

public void removeServer(String svname)

MBean operation which overides the BaseCluster's one It removes the corresponding member object from the members list and unregisters the corresponding ServerProxy MBean if this is the domain cluster. Note that the ClusterMember MBean is not unregistered (it will be done in case of the re-register of a new member in case the server is re-added to the domain). Remove a server from the cluster (jonasAdmin)

Specified by:

removeServer in interface BaseClusterMBean

Overrides:

removeServer in class BaseCluster

Parameters:

svname - logical name of the server
