Class ActiveMQClient

  • public final class ActiveMQClient
extends java.lang.Object
    Utility class for creating ActiveMQ Artemis ClientSessionFactory objects.

    Once a ClientSessionFactory has been created, it can be further configured using its setter methods before creating the sessions. Once a session is created, the factory can no longer be modified (its setter methods will throw a IllegalStateException.

        Warning: This method has to be called before any clients or servers is started on the JVM otherwise previous ServerLocator would be broken after this call.

      • initializeGlobalThreadPoolProperties

        public static void initializeGlobalThreadPoolProperties()
        Initializes the global thread pools properties from System properties. This method will update the global thread pool configuration based on defined System properties (or defaults if they are not set). The System properties key names are as follow: ActiveMQClient.THREAD_POOL_MAX_SIZE_PROPERTY_KEY="activemq.artemis.client.global.thread.pool.max.size" ActiveMQClient.SCHEDULED_THREAD_POOL_SIZE_PROPERTY_KEY="activemq.artemis.client.global.scheduled.thread.pool.core.size The min value for max thread pool size is 2. If the value is not -1, but lower than 2, it will be ignored and will default to 2. A value of -1 configures an unbounded thread pool. Note: If global thread pools have already been created, they will not be updated with these new values.

      • setGlobalThreadPoolProperties

        public static void setGlobalThreadPoolProperties​(int globalThreadMaxPoolSize,
                                                 int globalScheduledThreadPoolSize)
        Allows programmatical configuration of global thread pools properties. This method will update the global thread pool configuration based on the provided values notifying all globalThreadPoolListeners. Note: If global thread pools have already been created, they will not be updated with these new values. The min value for globalThreadMaxPoolSize is 2. If the value is not -1, but lower than 2, it will be ignored and will default to 2. A value of -1 configures an unbounded thread pool.

        Create a ServerLocator which creates session factories using a static list of transportConfigurations, the ServerLocator is not updated automatically as the cluster topology changes, and no HA backup information is propagated to the client
        Parameters:
        ha - The Locator will support topology updates and ha (this required the server to be clustered, otherwise the first connection will timeout)

      • createServerLocatorWithoutHA

        public static ServerLocator createServerLocatorWithoutHA​(DiscoveryGroupConfiguration groupConfiguration)
        Create a ServerLocator which creates session factories from a set of live servers, no HA backup information is propagated to the client

        The UDP address and port are used to listen for live servers in the cluster

        Parameters:
        groupConfiguration -
        Returns:
        the ServerLocator

      • createServerLocator

        Create a ServerLocator which creates session factories from a set of live servers, no HA backup information is propagated to the client The UDP address and port are used to listen for live servers in the cluster
        Parameters:
        ha - The Locator will support topology updates and ha (this required the server to be clustered, otherwise the first connection will timeout)

      • createServerLocatorWithHA

        public static ServerLocator createServerLocatorWithHA​(TransportConfiguration... initialServers)
        Create a ServerLocator which will receive cluster topology updates from the cluster as servers leave or join and new backups are appointed or removed.

        The initial list of servers supplied in this method is simply to make an initial connection to the cluster, once that connection is made, up to date cluster topology information is downloaded and automatically updated whenever the cluster topology changes.

        If the topology includes backup servers that information is also propagated to the client so that it can know which server to failover onto in case of live server failure.

        Parameters:
        initialServers - The initial set of servers used to make a connection to the cluster. Each one is tried in turn until a successful connection is made. Once a connection is made, the cluster topology is downloaded and the rest of the list is ignored.
        Returns:
        the ServerLocator

      • createServerLocatorWithHA

        public static ServerLocator createServerLocatorWithHA​(DiscoveryGroupConfiguration groupConfiguration)
        Create a ServerLocator which will receive cluster topology updates from the cluster as servers leave or join and new backups are appointed or removed.

        The discoveryAddress and discoveryPort parameters in this method are used to listen for UDP broadcasts which contain connection information for members of the cluster. The broadcasted connection information is simply used to make an initial connection to the cluster, once that connection is made, up to date cluster topology information is downloaded and automatically updated whenever the cluster topology changes.

        If the topology includes backup servers that information is also propagated to the client so that it can know which server to failover onto in case of live server failure.

        Parameters:
        groupConfiguration -
        Returns:
        the ServerLocator
