Abstract: A messaging service is described that incorporates messages into cached link lists. The messages are not yet acknowledged as having been received by one or more consumers to whom the messages were sent. A separate link list exists for each of a plurality of different message priority levels. Messages within a same link list are ordered in their link list in the same order in which they where received by the messaging service. At least one of the link lists contains an element that represents one or more messages that are persisted but are not cached in any of the cached link lists.

Abstract: A method, apparatus, and system are provided for Message Oriented Middleware virtual provider distribution. In one embodiment, MOM nodes are created. An MOM virtual provider from MOM virtual providers is selected for each of the plurality of MOM nodes. The MOM nodes run the MOM virtual providers.

Abstract: A method is described that automatically invokes in software a method call to a messaging service in response to an awareness that a proxy for a messaging service resource is needed. The method call requests the messaging service to create the messaging service resource.

Abstract: Methods and apparatuses for buffering enterprise messages are described herein. In one embodiment, an exemplary process is provided to transmit, from a messaging server to a client, a first message indicating a size of a next enterprise message to be sent to the client. A second message is received from the client in response to the first message, where the second message indicates a buffer size available to store messages for the client. The next enterprise message is then delivered to the buffer of the client if the size of the next enterprise message is smaller than or equal to the size of the available buffer of the client. Other methods and apparatuses are also described.

Abstract: A system and method are provided for failover of a Message-Oriented Middleware (MOM) server instance in an MOM provider having multiple MOM server instances. In an embodiment, a first server node receives notification that an MOM server instance on a second server node is inoperative. The MOM server instance on the second server node may have one or more associated destinations. In an embodiment, the first server node attempts to obtain a lock for at least a portion of MOM server instance configuration information from a locking service. If the lock is obtained, the first server node may acquire the one or more destinations of the inoperative MOM server instance.

Abstract: A method, apparatus, and system are provided for separate and dedicated instances for Message Oriented Middleware-related processes. In one embodiment, a standard instance having standard nodes having an application load and an MOM load is identified. The MOM load is separated from each of the standard nodes. The MOM load is run at MOM nodes.
