Abstract: A connection manager and worker nodes of an application server are both capable to access and control a shared memory session table.

Abstract: A connection manager includes a dispatcher that dispatches requests to worker nodes in an application server according to a load balancing algorithm.

Abstract: A method is described that involves establishing a connection over a shared memory between a connection manager and a worker node. The shared memory is accessible to multiple worker nodes. Then sending, from the connection manager to the worker node over the connection, a first request containing a method call to a remote object on the worker node. Also sending, from the connection manager to the worker node over the connection, a second request containing a second method call to a second remote object on the worker node.

Abstract: A method is described that involves entering a notification of a request into a queue that supplies request notifications to a first worker node amongst a plurality of worker nodes. The first worker node is targeted to process the request. In response to the first worker node failing before the notification could be serviced from the first queue, the notification is moved from the first queue to a second queue that supplies request notifications to a second worker node amongst the plurality of worker nodes. After servicing the notification from the second queue, the request is transferred to the second worker node. A response to the request is then generated with the second worker node.

Abstract: A method is described that involves identifying which session a received request pertains to. The method also involves referring to information maintained for the session. The information comprises first information that identifies a queue that provides notifications of requests to a worker node that is assigned to handle the session. The method also involves entering a request for a session into a shared memory. The method also involves entering a notification of the request into the queue. The method also involves, after failure of the worker node, retracting the notification from the queue, and, identifying a new worker node to handle the session with a load balancing algorithm.

Abstract: A system and method to monitor worker threads within a Java virtual machine. At least one program is executed on the Java virtual machine to perform a task. A worker thread of the Java virtual machine is assigned to perform the task. Status information for the worker thread is generated and reported into memory external to the Java virtual machine to enable monitoring of the worker thread from external to the Java virtual machine.

Abstract: A system and method are described for performing data processing using shared memory and socket-like application programming interface. In one embodiment, a plurality of handles is employed and associated with a plurality of processes. The plurality of handles may serve as communication end-points for communication of data. Further, an application programming interface is employed to present the plurality of handles as the application programming interface for sockets for facilitating the communication of data compatible with a programming language. The data is communicated between the plurality of processes via the socket-like plurality of handles.

Abstract: A system and method for integrating different virtual machines (“VMs”). A first VM is loaded into an Application Server (“AS”) instance. The first VM includes standard features accessible through a standard native interface. A second VM is loaded into the AS instance including the standard features and extended features. The standard features provided by the second VM are accessed by native platform entities through a standardized native interface. The extended features provided by the second VM are accessed by the native platform entities through an adaptation interface.

Abstract: A system and method are described for implementing native methods within a Java environment. The native methods may be used, for example, as part of a startup framework for a cluster of Java application servers. In one embodiment, a class object for a the class containing the native methods is instantiated in a memory. After the class object is loaded, one or more function pointers are inserted within the class object. The function pointers include identification information identifying an implementation of the native methods.

Abstract: A system and method to monitor a virtual machine VM. The VM executes one or more applications. During executing of the one or more applications, local objects are created and stored within an internal heap maintained by the VM. Status data of the internal heap is published to monitoring memory external to the VM.

Abstract: A memory architecture includes at any given point in time a contiguous memory window located at a fixed virtual address space comprising a first context to be shared by a plurality of worker processes in an application server instance and at least a second context to be attached to only one of the plurality of worker processes in the application server instance.

Abstract: A system and method to monitor client sessions within a Java virtual machine. Client sessions are established within an application server instance to store session context data for each of the client sessions during the client sessions. At least two Java virtual machines are operated within the application server instance to service client requests received from clients associated with each of the client sessions. Status information about each of the client sessions is reported into shared memory external to the Java virtual machines to monitor each of the client sessions during operation of the Java virtual machines.
