A system and method can support asynchronous request/response in a network environment. A network protocol can utilize a load balancer to balance requests, such as HTTP requests, over a fast network interface, such as InfiniBand, to one or more nodes of an application server cluster. The system and method can attach headers to the requests such that the requests can be sent in an interleaved manner. The system and method can further allow for sending of large requests by breaking up the large requests into smaller portions, and sending each portion, interleaved, with other requests.

System and method for supporting asynchronous request/response in a network environment

In accordance with an embodiment, described herein is a system and method for supporting an object-based stateful protocol (for example, T3 protocol) in a multitenant application server environment. The system includes a domain with a plurality of server instances, and a plurality of partitions thereon, wherein two or more partitions can spread across a first server instance and a second server instance of the plurality of server instances. Each of the first and second server instances can include a single remote java virtual machine (RJVM) that manages connections established through a single server channel on that server instance using the object-based stateful protocol. The application server instance initiating the connections can associate each connection with a particular partition using a token, and use a smart stub to recover a failed connection. A standalone Java application can similarly initiate connections to an application server instance.

System and method for protocol support in a multitenant application server environment

Described herein are systems and methods for improving concurrency of a request manager for use in an application server or other environment. A request manager receives a request, and upon receiving the request the request manager associates a token with the request. A reference to the request is enqueued in each of a plurality of queues, wherein each queue stores a local copy of the token. A first reference to the request is dequeued from a particular queue, wherein when the first reference to the request is dequeued, the token is modified to create a modified token. Thereafter the request is processed. When other references to the request are dequeued from other queues, the other references to the request are discarded.

System and method for providing a linearizable request manager

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.
