A special type of message that contains administrative information about the message broker. They are sent by the broker to special advisory topics.
See Also advisory topic.
A group of special topics that are created by a message broker that are used for monitoring the state of the broker. The broker sends messages about a variety of internal broker events. Clients subscribing to these topics receive advisory messages about these objects.

An open source project that provides the messaging technology for Fuse MQ Enterprise.
An open source project that provides the OSGi runtime container used by Fuse MQ Enterprise.
A container that is created by a container on the same host. Child containers are run on the same host as their parent container, but each child runs in a separate JVM.
When created using the console's admin:create-container, a child container inherits the features, feature repositories, and configuration from its parent. When a child container is created using the fabric:container-create command, the fabric:contaier-create-child, command, or Fuse Management Console, it does not inherit any configuration from its parent.
Regardless of how they are created, child containers can be started and shutdown from their parent container's console without using SSH.
An application that uses the message broker to communicate with other applications. These applications use one of the broker's client API to connect to and interact with the broker.
A group of brokers among which clients can failover.
A virtual destination that serves as a proxy for multiple destinations. Producers can send messages to the composite destination an it will be automatically sent to all of the physical destinations that make up the composite destination.
See Also virtual destination.
A bridge between a client and a broker connector.
See Also transport connector, network connector, network of brokers.
An object that a client uses to create a connection to a broker. A factory supports attributes that configure the quality of service for the connections it creates.
An object that connects clients to a broker.
An application that consumes messages from a messaging destination.
A special destination used by the message broker to hold undeliverable messages.
A form of inversion of control, where an object’s external dependencies are given to it, either programmatically or through a framework that is driven by configuration information. The result is to decouple dependent objects and allow the dependencies to be resolved at run time.
A logical holding area for messages in a message broker. Clients publish messages to and consume messages from destinations.
A mechanism that advertises the list of available message brokers to message clients and other message brokers.
See Also dynamic discovery.
A message consumer that receives all messages published on a topic, including those published while the subscriber is inactive.
A mechanism for clients to become aware of the existence of brokers through the use of a discovery agent.
See Also discovery agent.
See Fabric Ensemble.
A mechanism that ensures that only one consumer connected to a queue can consume messages.
A group of containers that are connected to a common Fabric Ensemble. The ensemble makes it possible for all of the containers to share runtime information about the services deployed in each container and allows them to share common configuration profiles.
The service running inside a Fabric Container that is responsible for configuring and provisioning the container according to the profiles assigned to the container . It is also responsible for updating the registry with runtime information about the services in container.
A Apache Karaf-based container that is managed by a Fabric Agent.
See Also Fabric Agent.
A group of one or more Fabric Servers that provide a number of services that bind a fabric. These services include the Fabric Registry, dynamic load balancing, and location transparency.
See Also Fabric Registry, Fabric Server.
A ZooKeeper-based distributed registry that stores runtime and configuration information about the services in a fabric.
A server that, as part of a Fabric Ensemble, provides a number of services that bind a fabric. These services include the Fabric Registry, dynamic load balancing, and location transparency.
See Also Fabric Registry.
A transport that automatically moves to a new connection in the event that its current connection fails.
A cluster architecture where clients are able to migrate from a failed broker to a running broker.
A unit of OSGi deployment that enables you to deploy multiple bundles in a single step.
An XML file that defines one or more features.
A URL that points to a feature repository file.
A bundle that uses a POM file to specify its dependencies.
An open source project that provides a distributed runtime registry that provides configuration, deployment, and discovery services to a collection of distributed containers.
See Also fabric.
An abbreviation for internationalization, used in the context of preparing products, especially software and documentation, for use in more than one national locale and language.
An API that provides a way to bind an XML Schema to a representation in Java code.
A Java security framework for user-centric security to augment the Java code-based security.
An API specified in Java technology that provides Java applications with access to databases and other data sources.
A Java technology that supplies tools for managing and monitoring applications, system objects, devices, and service-oriented networks.
A Java API implementing a messaging standard that allows application components based on J2EE to create, send, receive, and read messages. It enables distributed communication that is loosely coupled, reliable, and asynchronous.
A set of APIs specified in Java technology that assists Java applications with interfacing to multiple naming and directory services.
An abbreviation for localization, used in the context of preparing products, especially software and documentation, for use in more than one national locale and language. Localization is the process of translating the elements of a product for a particular locale and language.
See Fabric Container.
The process of taking in-memory objects and converting them to a binary or textual format for transmission over a transport.
See Also unmarshalling.
A topology in which a single instance, the master, is active and one or more instances, the slaves, are ready to resume when the active instance stops.
An atomic unit of data that is passed between two or more clients. A message consists of three components:
headers—contain a predefined set of metadata that is used to communicate information about a message between the different parties that handle the message
properties—contain application defined metadata about a message to the different parties that handle the message
body—contains the messages payload
A collection of JMS messages that are assigned the same JMSXGroupID.
When used in conjunction with the JMSXGroupSeq message groups can be used to ensure that messages are processed in the proper sequence.
A string containing a boolean SQL statement using SQL 92 syntax that is used to select messages based on JMS message header properties.
A runtime directional link between brokers that is used to forward messages. Network bridges are created by network connectors.
See Also network connector.
A configuration entity used to link brokers together to form a network of brokers.
See Also network of brokers.
A group of brokers that are linked together to operate as a single logical unit.
A Apache Karaf-based container that is registered with a fabric, but is not managed by a Fabric Agent.
A registration property used by the OSGi Configuration Admin Service to identify a group of configuration attributes.
A messaging style where messages are sent between two known endpoints. This messaging style is typically implemented using queues.
An application that creates messages and posts them to a messaging destination.
A set of data that defines runtime artifacts and configuration settings for provisioning a Fabric Container.
A messaging style where message producers send(publish) messages to a destination and interested consumers can register(subscribe) to receive messages from the destination. This style of messaging is implemented using topics.
A destination that uses first in/first out semantics.
See Also destination.
See Fabric Registry.
A messaging pattern in which a message producer receives a message and returns a correlated message.
A consumer that indicates to the topic that every attempt is to be made to send messages that the consumer may have missed.
A JMS object that provides a single-threaded context for producing and consuming
messages. JMS clients use the Session object to create
producers, consumers, messages, and other artifacts used to work with messages.
A comprehensive programming and configuration model for modern Java-based enterprise applications the uses dependency injection.
See Also dependency injection.
See standalone container.
A container that is not part of a fabric and does not have a Fabric Agent installed.
A paradigm in which brokers receive messages, store them locally, and forwards the message to a recipient when it is able to do so. The message is only deleted once it has been successfully delivered.
A language agnostic, simple text-based protocol that allows clients to talk with any message broker supporting the protocol.
A destination that uses publish and subscribe semantics.
