    • Apparatus, processes, and computer readable storage media for processing received packets. A session memory, coupled to and shared by a plurality of packet processors, may store configuration and statistics information for a plurality of communication sessions. A session active memory may store session identifiers corresponding to packets currently being processed by the plurality of packet processors. A comparator may compare a session identifier extracted from a received packet with the stored session identifiers to determine if another packet belonging to the same session as the received packet is currently being processed. Forwarding logic may distribute received packets among the plurality of packet processors. In the case that another packet belonging to the same session as the received packet is currently being processed, the forwarding logic may wait until the processing of the another packet is complete before sending the received packet to one of the packet processors.
    • 装置,处理和用于处理接收的分组的计算机可读存储介质。 耦合到多个分组处理器并由多个分组处理器共享的会话存储器可以存储用于多个通信会话的配置和统计信息。 会话活动存储器可以存储对应于由多个分组处理器正在处理的分组的会话标识符。 比较器可以将从接收到的分组提取的会话标识与所存储的会话标识符进行比较,以确定属于与接收分组相同的会话的另一分组当前正在被处理。 转发逻辑可以在多个分组处理器之间分配接收的分组。 在属于与接收到的分组相同的会话的另一分组当前正在被处理的情况下,转发逻辑可以等待直到另一分组的处理完成,然后将所接收的分组发送到分组处理器之一。

    • Session management can be supported in a distributed transactional service system using a distributed transactional server and an affinity client. The affinity client operates to receive a service request from a user application and invoke at least one distributed transactional service provided by the distributed transactional server. The distributed transactional server operates to create and maintain a session for the user application when the at least one distributed transactional service is invoked, and the distributed transactional server further operates to determine an affinity scope associated with the session. The affinity scope, which is maintained on the affinity client, defines a routing scope within the distributed transactional service system, into which consequent requests in the session from the user application are dispatched.
    • 可以在使用分布式事务服务器和亲和性客户端的分布式事务服务系统中支持会话管理。 亲和力客户端操作以从用户应用接收服务请求,并且调用由分布式事务服务器提供的至少一个分布式事务服务。 当调用至少一个分布式事务服务时,分布式事务服务器操作以创建和维护用户应用程序的会话,并且分布式事务服务器进一步操作以确定与该会话相关联的亲和范围。 在亲和度客户端上维护的亲和范围定义了分布式事务服务系统内的路由范围,在该事务处理服务系统中调度会话中的后续请求。

    • A computer-implemented method is disclosed for providing a user with a consistent view of user session in a distributed environment. The method includes providing application servers with data storage means for storing part of the user context for that user session, defining thereby for each user session a set of application servers having each an affinity with the user session. Each application server is configured to process a software application that is required for that user session. At a routing means, performing the following steps with at least one data processor: receiving request from the user and routing transactions of the user session toward the application servers having an affinity with the user session in order to fulfill the request, assigning to the user session a correlation record (DCX) arranged to include Affinity Keys, each Affinity Key indicating an application server that has an affinity with the user session for a given software application, propagating the correlation record with transactions, allowing thereby the routing means to target the application servers that are linked to the user context of that user session and that process the software application relevant to process the transaction.
    • 公开了一种计算机实现的方法,用于在分布式环境中向用户提供用户会话的一致视图。 该方法包括向应用服务器提供数据存储装置,用于存储该用户会话的部分用户上下文,从而为每个用户会话定义一组具有与用户会话相关的应用服务器。 每个应用程序服务器被配置为处理该用户会话所需的软件应用程序。 在路由装置中,使用至少一个数据处理器执行以下步骤:从用户接收请求并将用户会话的事务路由到与用户会话具有亲和度的应用服务器以便完成该请求,分配给用户 会话相关记录(DCX),其被布置为包括亲和度密钥,每个亲和密钥指示与给定软件应用与用户会话具有亲和性的应用服务器,将相关记录传播到交易中,从而允许路由装置将目标应用 链接到该用户会话的用户上下文的服务器,并处理与处理该事务相关的软件应用程序。

    • A mechanism for enabling session information to be shared across multiple processes in a multi-process environment is disclosed. There is provided a shared persistent memory-mapped file in a file system, which is mapped to the memory space of each of the processes. This file is used by all of the processes to store session information. Because the memory space of each process is mapped to the shared file, each process is able to access and manipulate all of the sessions in the system. Thus, sessions are no longer maintained on a process-specific basis. Rather, they are maintained on a centralized, shared basis. As a result, different requests pertaining to the same session may be serviced by different server processes without any adverse effects. Each process will be able to access and manipulate all of the state information pertaining to that session. By enabling session information to be shared, this mechanism eliminates the session management errors experienced by the prior art.
    • 公开了一种用于在多进程环境中跨多个进程共享会话信息的机制。 在文件系统中提供了共享的永久存储器映射文件,其被映射到每个进程的存储器空间。 该文件由所有进程用于存储会话信息。 因为每个进程的内存空间映射到共享文件,所以每个进程都能够访问和操作系统中的所有会话。 因此,会话不再在流程特定的基础上维护。 相反,它们保持在一个集中的共享基础上。 因此,与同一会话有关的不同请求可能由不同的服务器进程提供服务而没有任何不利影响。 每个进程将能够访问和操纵与该会话有关的所有状态信息。 通过启用会话信息被共享,该机制消除了现有技术所遇到的会话管理错误。
