摘要： A copy method is disclosed to provide a duplicate copy of source data where the duplicate copy is consistent with the source data as of a designated time. The method includes creating a copy-on-write relationship between specified source data and an original image cache, utilizing an application outboard of the designated host application to copy all items of source data and their associated locations to a secondary data object without regard to whether the items source data have been updated since creating the copy-on-write relationship, and copying a specified amount of contents of the original image cache to the secondary data object. The specified amount includes contents of the original image cache as of completion of the utilizing operation. In addition, the method includes permitting copy-on-write relationship to continue during the utilizing operation and during at least part of the copying operation.

摘要： Any node in a multi-node processing system may be employed to route commands to a selected group of one or more nodes, and initiate local command execution if permitted by local security provisions. The system includes multiple application nodes interconnected by a network, and one or more administrator nodes each coupled to at least one application node. Each administrator node has assigned security credentials. The process starts when the administrator node transmits input to one of the application nodes (an “entry” node). The input includes a command and routing information specifying a list of desired application nodes (“destination” nodes) to execute the command. In response to this input, the entry node transmits messages to all destination nodes to (1) log-in to the destination nodes as the originating administrator node, and (2) request the destination nodes to execute the command. Consulting locally stored security information, each destination node determines whether the entry node's log-in should succeed. If so, the destination node consults locally stored authority information to determine whether the initiating administrator node has authority to execute the requested command. If so, the destination node executes the command. The destination node sends the entry node a response representing the outcome of command execution. The entry node organizes such responses and provides a representative output.
摘要翻译： 可以使用多节点处理系统中的任何节点来将命令路由到所选择的一个或多个节点的组，并且如果被本地安全规定允许，则启动本地命令执行。 系统包括由网络互连的多个应用节点，以及每个耦合到至少一个应用节点的一个或多个管理员节点。 每个管理员节点都分配了安全凭证。 当管理员节点向其中一个应用节点（“条目”节点）发送输入时，该过程开始。 输入包括指定用于执行命令的期望的应用节点（“目的地”节点）的列表的命令和路由信息。 响应于该输入，入口节点将消息发送到所有目的地节点，以（1）作为始发管理员节点登录到目的地节点，以及（2）请求目的节点执行该命令。 咨询本地存储的安全信息，每个目标节点确定入口节点的登录是否应该成功。 如果是，则目的地节点查询本地存储的权限信息，以确定发起管理员节点是否具有执行请求的命令的权限。 如果是，则目的节点执行该命令。 目的地节点向入口节点发送表示命令执行结果的响应。 入口节点组织此类响应并提供代表性的输出。

摘要： Disclosed are a method, embodiable in computer readable program code, and a system for providing server-to-server event logging. A server-to-server event message is generated including 1) an event identifier, 2) any text insert pertinent to the event message, and 3) a source trail indicating the origin and history of the event, the source trail comprising an identifier of any server forwarding the event, each identifier separated by a special character, so that the origin and any subsequently transmitting servers may be known. Further, the source trail of a received server-to-server event message is parsed to determine each identifier in the source trail, and the event message transmitted to a receiving server only if the receiving server identifier is absent from the parsed source trail, thus preventing any loops which might cause the event to be repeated. Additionally, a receiving server has a listing of events by event identifier with corresponding text messages in the text language of the receiving server. The received event identifier is found in the listing, and the receiving server logs the event, using the identified text message in the listing in the text language of the receiving server, and employing the text inserts.

摘要： A data processing system using a client-server configuration provides a method and apparatus for generating and managing multiple copies of client data files. A server coupled to a plurality of client systems organizes sets of storage volumes into storage pools. Primary copies of the client data files are stored in primary storage pools while additional back-up copies of the client data files are copied to secondary storage pools, called copy storage pools. A server database maintains directory information about the original client data file and reference information about the location of the multiple file copies within the server. A storage manager provides a control center within the server, directing and coordinating the transfer of files between the various storage pools, and updating the server database with directory and reference location information.
