Class ClusteringConstants.Parameters

  • Enclosing class:
    ClusteringConstants
    public static final class ClusteringConstants.Parameters
extends Object
    The main cluster configuration parameters

    • 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"
        See Also:
        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

        See Also:
        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.

        See Also:
        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"
        See Also:
        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
