Enclosing class:

ClusteringConstants

public static final class ClusteringConstants.Parameters
extends Object

The main cluster configuration parameters

Field Summary

static String	APPLICATION_DOMAIN This parameter is only valid when the "mode" parameter is set to "application" This indicates the domain in which the the applications being load balanced are deployed.
static String	ATMOST_ONCE_MSG_SEMANTICS Maintain atmost-once message processing semantics
static String	AVOID_INITIATION Do not automatically initialize the cluster.
static String	DOMAIN The clustering domain/group.
static String	IS_ACTIVE Indicates whether this member is ACTIVE or PASSIVE
static String	LOAD_BALANCE_EVENT_HANDLER This is the even handler which will be notified in the case of load balancing events occurring.
static String	MEMBERSHIP_LISTENER The implementaion of
static String	MEMBERSHIP_SCHEME The membership scheme used in this setup.
static String	MODE Indicates the mode in which this member is running.
static String	PRESERVE_MSG_ORDER Preserve message ordering.
static String	SYNCHRONIZE_ALL_MEMBERS When a Web service request is received, and processed, before the response is sent to the client, should we update the states of all members in the cluster? If the value of this parameter is set to "true", the response to the client will be sent only after all the members have been updated.

Field Detail

MEMBERSHIP_SCHEME

public static final String MEMBERSHIP_SCHEME

The membership scheme used in this setup. The only values supported at the moment are "multicast" and "wka"

Constant Field Values

DOMAIN

public static final String DOMAIN

The clustering domain/group. Nodes in the same group will belong to the same multicast domain. There will not be interference between nodes in different groups.

See Also:

Constant Field Values

MODE

public static final String MODE

Indicates the mode in which this member is running. Valid values are "application" and "loadBalance"

application - This member hosts end user applications loadBalance - This member is a part of the load balancer cluster

Constant Field Values

LOAD_BALANCE_EVENT_HANDLER

public static final String LOAD_BALANCE_EVENT_HANDLER

This is the even handler which will be notified in the case of load balancing events occurring. This class has to be an implementation of org.apache.axis2.clustering.LoadBalanceEventHandler

This entry is only valid if the "mode" parameter is set to loadBalance

See Also:

Constant Field Values

APPLICATION_DOMAIN

public static final String APPLICATION_DOMAIN

This parameter is only valid when the "mode" parameter is set to "application"

This indicates the domain in which the the applications being load balanced are deployed.

Constant Field Values

SYNCHRONIZE_ALL_MEMBERS

public static final String SYNCHRONIZE_ALL_MEMBERS

When a Web service request is received, and processed, before the response is sent to the client, should we update the states of all members in the cluster? If the value of this parameter is set to "true", the response to the client will be sent only after all the members have been updated. Obviously, this can be time consuming. In some cases, such this overhead may not be acceptable, in which case the value of this parameter should be set to "false"

Constant Field Values

AVOID_INITIATION

public static final String AVOID_INITIATION

Do not automatically initialize the cluster. The programmer has to explicitly initialize the cluster.

See Also:

Constant Field Values

PRESERVE_MSG_ORDER

public static final String PRESERVE_MSG_ORDER

Preserve message ordering. This will be done according to sender order

See Also:

Constant Field Values

ATMOST_ONCE_MSG_SEMANTICS

public static final String ATMOST_ONCE_MSG_SEMANTICS

Maintain atmost-once message processing semantics

See Also:

Constant Field Values

IS_ACTIVE

public static final String IS_ACTIVE

Indicates whether this member is ACTIVE or PASSIVE

See Also:

Constant Field Values

MEMBERSHIP_LISTENER

public static final String MEMBERSHIP_LISTENER
