    • A method and apparatus in a distributed data processing system for processing requests for documents. A request is received from a user for a selected page at a server. The selected page is returned to the user with a unique token, wherein each user is sent a unique token. Responsive to receiving a new request for a page, a determination is made as to whether the new request includes the unique token. Responsive to receiving the new request including the unique token, a determination is made as to whether a previous request from this user is simultaneously being processed by the server. Responsive to a new request having been received for a document while another prior request is pending, the new request is processed by either rejecting the new request, or by canceling the previous request and processing the new request, or by delaying the processing of the new request until the previous request has completed.
    • 用于处理文件请求的分布式数据处理系统中的方法和装置。 从用户接收到服务器上所选页面的请求。 所选页面被返回给具有唯一令牌的用户,其中每个用户被发送唯一的令牌。 响应于接收到对页面的新请求,确定新请求是否包括唯一令牌。 响应于接收到包括唯一令牌的新请求,确定来自该用户的先前请求是否同时被服务器处理。 响应于在另一个先前请求正在等待的时候已经接收到一个文档的新请求,新的请求被拒绝新的请求,或者通过取消先前的请求和处理新的请求来处理,或者通过延迟处理新的请求 请求直到上一个请求完成。

    • A system and method for controlling duplicate transaction submission in a web browser/web server environment. The client web browser is modified to include a process duplicate action select (e.g. duplicate mouse “clicks”) detection. This process establishes a variable for an action indicating whether the action has been previously selected. Upon selection, the process tests the action variable and passes the transaction request if not previously submitted and returns an error otherwise. The server process has been augmented with a duplicate transaction process. The server software inserts a _tranid parameter into each of a plurality of selected pages returned to a browser for transaction processing. The server maintains a record of the last used jranid. The server compares a tranid returned in a user request to the recorded value. If previously processed, an error is returned to the requester. If not previously processed, the recorded “last transaction id” is updated and the request fulfilled.
    • 一种用于控制Web浏览器/ Web服务器环境中重复事务提交的系统和方法。 客户端Web浏览器被修改为包括过程重复动作选择(例如,重复的鼠标“点击”)检测。 此过程为一个动作建立一个变量,指示该动作是否已经被选择。 选择后,该过程将测试操作变量,如果先前未提交,则传递事务请求,否则返回错误。 已经通过重复的事务处理来增加服务器进程。 服务器软件将_tranid参数插入返回到浏览器进行事务处理的多个选定页面中的每一个。 服务器维护了最后使用的jranid的记录。 服务器将用户请求中返回的tranid与记录的值进行比较。 如果先前处理过,则会向请求者返回错误。 如果以前未被处理,则记录的“最后一个事务ID”被更新并且满足请求。

    • Embodiments of the disclosure relate to the management of memory pages available for pin operations by groups of processors in a multiprocessor system to reduce cache contention and improve system performance. An exemplary embodiment comprises a system that may include interconnected processors, a global count of the number of pages available for pinning, and a plurality of local counts of pages available for pinning by groups of processors. Each local count may be in proximity to a processor group and include a subset of the pages allocated from the global count that are available for pinning by processors in the group. The local counts are adjusted accordingly in response to page pinning and unpinning by processors in the respective processor groups.
    • 本公开的实施例涉及通过多处理器系统中的处理器组来管理可用于引脚操作的存储器页面,以减少高速缓存争用并提高系统性能。 示例性实施例包括可以包括互连处理器的系统,可用于钉扎的页数的全局计数,以及可用于处理器组的固定的多个可用页面的本地计数。 每个本地计数可以接近处理器组,并且包括从全局计数分配的可用于组中的处理器的固定的页面的子集。 响应于相应处理器组中的处理器的页面固定和拆分来调整本地计数。
