Abstract:
A system and method can provide a scalable data storage in a middleware environment. The system can include a cluster of replicated store daemon processes in a plurality of processing nodes, wherein each machine node can host a replicated store daemon process of the cluster of replicated store daemon processes. Additionally, the system can include one or more replicated stores associated with an application server the processing node. The replicated store daemon cluster can persist data from a replicated store to another node, the other node also being associated with the replicated store daemon cluster. The system and method can additionally support a messaging service in a middleware environment. The messaging service can use the replicated store to store a copy of a message in the local processing node and on another processing node associated with the same replicated store daemon cluster.
Abstract:
A system includes a resource adapter module in the form of executable code by a processor, the resource adapter module to, interact with an application running on an application server by receiving calls from applications, and provide communication between the application and any JMS provider by relaying the calls to the JMS provider.
Abstract:
A system has at least one requesting application residing upon a requesting application server, a cluster of processing message servers, a resource adapter in the form of executable code being executed by a processor on a first computer, the resource adapter to receive a request from the requesting application; transmit the request to the cluster of processing message servers; monitor processing of the request on the cluster of processing message servers; handling any exception in the processing of the request; and responding to the requesting application when the processing is complete. The system also includes an interposed transaction manager in the form of executable code being executed by a processor, the interposed transaction manager to receive transactional operations associated with the requests, and providing transaction guarantees related to the transactional operations.

Abstract:
In accordance with an embodiment, a system and method provides a dynamic clustered messaging service in an application server environment. A cluster includes one or more servers operating within the application server environment and is configured to vary a number of the servers based on a service load of applications running on the cluster. The number also varies based on failure and restart of the servers. A messaging service for communicating messages between components of the applications includes instances of messaging service artifacts running on the one or more servers. A placement engine operating on the cluster is configured to migrate the instances of messaging service artifacts between the one or more servers based on a set of rules as the number of the one or more servers in the cluster expands and contracts and as a number of the instances of messaging service artifacts expands and contracts.
Abstract:
A computer-controlled method can include providing a resource adapter with an object wrapper having a plurality of features, a wrapper generation tool receiving a change to be made to the object wrapper, and the wrapper generation tool generating a new object wrapper based on the change. The resource adapter can receive an object from a messaging provider, adapt the object based on the newly generated object wrapper, and send the wrapped object to an application.
