Abstract: A system and method for providing a message bus component or version thereof (referred to herein as an implementation), and a messaging application program interface, for use in an enterprise data center, middleware machine system, or similar environment that includes a plurality of processor nodes together with a high-performance communication fabric (or communication mechanism) such as InfiniBand. In accordance with an embodiment, the messaging application program interface enables features such as asynchronous messaging, low latency, and high data throughput, and supports the use of in-memory data grid, application server, and other middleware components.

Abstract: Systems and methods are provided for providing scatter/gather data processing. In accordance with an embodiment, a such a system can include a cluster of one or more high performance computing systems, each including one or more processors and a high performance memory. The cluster communicates over an InfiniBand network. The system can also include a middleware environment, executing on the cluster, that includes one or more application server instances. The system can further include a plurality of muxers. Each application server instance includes at least one muxer, and each muxer is operable to collect data from a plurality of locations in the high performance memory, and transfer the data in bulk.

Abstract: A system and method for providing a middleware machine or similar platform. In accordance with an embodiment the system (referred to herein in some implementations as “Exalogic”) comprises a combination of high performance hardware, together with an application server or middleware environment, to provide a complete Java EE application server complex which includes a massively parallel in-memory grid, can be provisioned quickly, and can scale on demand. In accordance with an embodiment, the system can be deployed as a full, half, or quarter rack, or other configuration, that provides an application server grid, storage area network, and InfiniBand network, which support the execution of an application server, middleware or other functionality such as, for example, WebLogic Server, JRockit or Hotspot JVM, Oracle Linux or Solaris, and Oracle VM. Additional features of the system can include, e.g. Zero Buffer Copies, Scatter/Gather I/O, T3 Connections, and Lazy Deserialization.

Abstract: A system and method can support one-way Remote Method Invocation (RMI) session replication in a middleware machine environment, such as a server cluster. The server cluster can include a primary application server and a secondary application server. The primary application server receives a request with a session from a client, maintain the session information, and replicate the session information to a secondary application server using one-way Remote Method Invocation (RMI). The primary application server can then respond to the client based on the session information after receiving a return message of the one-way RMI from a network socket associate with the primary application server. The benefit of using one-way RMI is that the primary application server does not have to wait for an acknowledgment from the secondary application server instance, since the underlying transport protocol guarantees that the session data has been successfully transmitted to the second server instance.

Abstract: A system and method for partial object dematerialization within a virtual machine (VM), and particularly Java Virtual Machines. In accordance with an embodiment, the system allows for applying partial object dematerialization to situations where the object is either created locally, or is retrieved from external code where it might have already escaped. In accordance with an embodiment, the system comprises a computer; a virtual machine for executing a software application; memory space for the application byte code and the generated machine code; and a compiler with an object dematerializer, and dematerializer injector. Runtime partial object dematerialization code is injected into the intermediate code representation in such a way that additional or standard optimizer techniques can be applied to it.
