摘要:
Disclosed is a server having a plurality of clients coupled to the server at client nodes, and coupled to a plurality of receivers. Events, which may range from a successful completion message to a major error alert, may be generated relating to the server or to the client nodes. A method is disclosed for dynamically selectively distributing the events to particular ones of the receivers, in response to a selective enabling/disabling of the events to each receiver. The method with respect to client nodes comprises: upon opening a session of a client node, the selectively enabled events/receivers relating to the client node are determined. Upon the selective enabling/disabling occurring during the session of the client node, the determined selectively enabled events/receivers relating to the client node are dynamically updated. Then, upon occurrence of an event relating to a client node, the event is distributed to ones of the receivers having been selectively enabled for the event in the determining and the dynamically updating steps. Additionally, classes of events or wild card groups of client nodes may be enabled.

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.

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.

Provided are a method, system, and article of manufacture wherein one client node is selected from a plurality of client nodes. A determination is made that an object corresponding to a client node has to be stored. A determination is made as to whether the object has already been stored in the server node by the one selected client node. The object is stored at the server node, in response to determining that the object has not already been stored in the server node by the one selected client node.

Provided are a system, method, and program for grouping backup objects stored in backup storage. A backup group is created and a plurality of backup objects are added as members of the backup group in separate backup transactions. The backup objects added to the backup group are stored to backup storage.

A system and method for storing data in a network computing environment. The network includes a source server that will receive data to be stored from a client and target servers that have locally attached physical storage media. A server-to-server protocol is used to establish a communication connection between the source server and target server while programming allows the storage of the data from the source server on the physical storage at the target server, while also creating a virtual volume at the source server on which the data is also stored. From the perspective of the client, the data appears to be stored at the source server on locally attached storage media. The present invention eliminates the requirement for actual physical media locally attached to the source server.
