    • In a multi-node computer system, file access by a failed node is limited. Upon receipt on an indication of a node failure, a fencing command is sent to disks in a disk subsystem to which the failed node has access. If the fencing command sent to a disk fails, the fencing command is sent to a server having access to at least one disk in a disk subsystem to which the failed node has access to limit access by the failed node to the disk in the disk subsystem. If the fencing command sent to the server does not result in limiting access by the failed node to all the disks in the disk subsystem, sending the command to another server having access to at least one disk in the disk subsystem to limit access by the failed node to the disks in the disk subsystem. The fencing command may be sent to various servers until access by the failed node to all the disks in the disk subsystem is limited or until the fencing command has been sent to all the servers. The fencing command may be sent one at a time to servers having access to the disks in the disk subsystem, may be sent concurrently to all the servers having access to the disks in the disk subsystem, or may be forwarded from one server to another.
    • 在多节点计算机系统中,故障节点的文件访问受到限制。 在接收到节点故障的指示时,防护命令被发送到故障节点有权访问的磁盘子系统中的磁盘。 如果发送到磁盘的防护命令发生故障,则将fencing命令发送到访问磁盘子系统中至少一个磁盘的服务器,故障节点可以访问该磁盘子系统,以将故障节点访问限制在磁盘子系统中的磁盘 。 如果发送到服务器的防护命令不会导致将故障节点访问磁盘子系统中的所有磁盘,请将命令发送到具有访问磁盘子系统中至少一个磁盘的另一个服务器,以限制访问失败 节点到磁盘子系统中的磁盘。 可以将防护命令发送到各种服务器,直到故障节点对磁盘子系统中的所有磁盘的访问受到限制,或者直到防护命令已发送到所有服务器。 可以一次将防护命令发送到具有访问磁盘子系统中的磁盘的服务器,可以同时发送到具有访问磁盘子系统中的磁盘的所有服务器,或者可以从一个服务器转发到另一个服务器。

    • A platform independent model for exchanging information among numerous entities in a justice system with diverse system components is implemented in a hub and spoke arrangement. Each spoke includes a software agent that communicates with a system component of an entity of the justice system, translates from a common communication format to a communication format of the system component, and manages the timing of the flow of information to/from the system component. The hub includes an information broker that communicates with each agent in the common communication format, determines what information is needed by which entity, and routes the needed information to/from respective agents for the entities that need the information. The platform independent model includes a plurality of traceable and linked UML models that define the information broker from a business use case model through to a platform independent solution model for implementation on a given solution platform. Since these UML models are readily modifiable and traceable for changes to the justice system, they facilitate implementation of the system in a cost-effective manner from one customer to the next without requiring system redesign.
    • 在具有不同系统组件的司法系统中的众多实体之间交换信息的平台独立模型是以轮毂和轮辐方式实现的。 每个辐条包括与司法系统的实体的系统组件通信的软件代理,从公共通信格式转换为系统组件的通信格式,并且管理到/从系统组件的信息流的定时 。 集线器包括以公共通信格式与每个代理进行通信的信息代理,确定哪个实体需要什么信息,并且向需要该信息的实体的相应代理路由所需信息。 独立于平台的模型包括多个可跟踪和链接的UML模型,其将信息代理从业务用例模型定义为在给定解决方案平台上实现的与平台无关的解决方案模型。 由于这些UML模型对于司法系统的改变而言可以随时修改和追溯,所以它们有助于从一个客户到下一个客户以低成本效益的方式实现系统,而无需重新设计系统。
