摘要： A system and a method for dynamic or as-needed activation of Remote Method Invocation (RMI) layer remote objects in response to a client request. Object activation allows the system to clean up or delete currently unused remote objects, and then reactivate them when a client actually needs them. An object implementation can first be created in response to a client request. The client receives a remote reference (remote ref) and an activation identifier (activation id) identifying that particular implementation. The implementation can subsequently be cleaned up or deleted during garbage collection so as to save server resources, or alternatively the object can be reused if the system is set up to maintain a pool of objects. When the client requests the same object at a later point in time, the system activates an object based on the activation ID previously received from the server.
摘要翻译：用于响应于客户端请求动态或按需激活远程方法调用（RMI）层远程对象的系统和方法。对象激活允许系统清理或删除当前未使用的远程对象，然后在客户端实际需要时重新激活它们。可以首先根据客户端请求创建对象实现。客户端接收远程引用（远程引用）和标识该特定实现的激活标识符（激活标识符）。随后可以在垃圾收集期间清除或删除该实现，以便节省服务器资源，或者如果系统设置为维护对象池，则可以重新使用该对象。当客户端在稍后的时间点请求相同的对象时，系统将基于先前从服务器接收到的激活ID激活对象。

摘要： A method for using available server threads to process resources and reduce the overall time of performing XA interactions in two-phase commit protocol implemented by the transaction manager. A TM processing XA interactions dispatches interaction commands for multiple resources to a thread manager, which dispatches the commands to idle server threads. In one embodiment, the TM attempts to dispatch all but one of the interaction commands to separate threads. The primary thread then processes the remaining resource command. Any commands relating to dispatch requests that were unable to be dispatched to separate threads due to unavailability are processed by the primary thread. Once the primary server has processed its interaction commands and received a signal indicating the threads receiving dispatch requests have completed their respective processing of dispatched commands, the next group of commands is processed in a similar manner.
摘要翻译：一种使用可用的服务器线程处理资源并减少由事务管理器实现的两阶段提交协议执行XA交互的总时间的方法。 TM处理XA交互将多个资源的交互命令分配给线程管理器，线程管理器将命令分派到空闲服务器线程。在一个实施例中，TM尝试将除了一个交互命令的所有命令分发到单独的线程。然后主线程处理剩余的资源命令。任何与由于不可用而无法分派到单独线程的调度请求相关的命令都由主线程处理。一旦主服务器处理了其交互命令并且接收到指示接收分派请求的线程的信号已经完成了它们对分派命令的相应处理，则以类似的方式处理下一组命令。

摘要： A system and method for application server with overload protection. A system, for example a server or a cluster, is designed to generate a message, and/or reject further work, whenever the server becomes overloaded. It does this in a processor-efficient manner so as not to place even more strain on the already burdened server. The rejection message or action is customizable. In accordance with an embodiment, the system determines where the request would appear in a priority queue, and rejects those further down the queue. It does this quickly and with minimal processing time by determining to which workload manager the request is going to be delivered.

摘要： A system and a method for scheduling disk writes for use with an application server, transactional system, or other server. The disk scheduler and method is independent of the underlying operating system and the disk hardware. This allows it to be used without porting to the various settings in which application server might be deployed. In some embodiments, a high-performance, transactional filestore is also provided to minimize the latency of small, synchronous writes to disk. The implementation uses a log-structured file system combined with disk scheduling. By relaxing the requirement that log records be physically contiguous, every modification to the disk can be scheduled.

摘要： The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network. Engine nodes in the engine tier can process SIP messages and can read/write state information from/to the state tier. State tier can maintain state information in a set of partitions of one or more replicas which contain duplicate information. The engine nodes can be adapted to detect and report replica failures and the replicas can in turn be adapted to detect and report engine node failures. Replicas can detect faults with an engine node if the engine node fails to poll the replica for a specified period of time and can then report the failure. The engine node can detect failures of a replica when reading or writing state information and can report the failure to another replica, which can be responsible for updating the partition view to exclude dead replicas.

摘要： A clustered enterprise distributed processing system. The distributed processing system includes a first and a second computer coupled to a communication medium. The first computer includes a virtual machine (JVM) and kernel software layer for transferring messages, including a remote virtual machine (RJVM). The second computer includes a JVM and a kernel software layer having a RJVM. Messages are passed from a RJVM to the JVM in one computer to the JVM and RJVM in the second computer. Messages may be forwarded through an intermediate server or rerouted after a network reconfiguration. Each computer includes a smart stub having a replica handler, including a load balancing software component and a failover software component. Each computer includes a duplicated service naming tree for storing a pool of smart stubs at a node.

摘要： The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network environment. The engine tier can send, receive and process various messages. The state tier can maintain in-memory state data associated with various SIP sessions. A near cache can be residing on the engine tier in order to maintain a local copy of a portion of the state data contained in the state tier. Various engines in the engine tier can determine whether the near cache contains a current version of the state needed to process a message before retrieving the state data from the state tier. Accessing the state from the near cache can save on various latency costs such as serialization, transport and deserialization of state to and from the state tier. Furthermore, the near cache and JVM can be tuned to further improve performance of the SIP server.

摘要： The SIP server can be comprised of an engine tier and a state tier distributed on a cluster network environment. The engine tier can send and receive messages and execute various processes. The state tier can maintain in-memory state data associated with various SIP sessions. For example, the state tier can store various long lived data objects and the engine tier can contain short lived data objects. The state data can be maintained in partitions comprised of state replicas. A load balancer can receive incoming message traffic and distribute it to the engine tier for processing. When processing a message, the engine can pull state data objects from the state tier, use the objects and push them back to the state tier after processing is complete. If one state replica is unavailable, such as during garbage collection, the engine can retrieve the objects from another replica in the partition.
