摘要:
Provided are a method, system and article of manufacture, wherein a plurality of broadcast messages are sent from at least one node of a plurality of nodes of a network. A node is discovered based on a received message. An entry is stored, wherein the entry corresponds to the node and a timestamp that indicates a time at which the node was last discovered. A notification is made that the node is offline, in response to determining that a predetermined time has elapsed since the timestamp was last updated.
摘要:
A technique for enabling a client to access the resources of different servers without having specific knowledge of which server has which resources. The client generates multiple copies of a request that identifies an operation to be performed, such as a copy type operation. The client sends a copy of the request to each server. The server determines whether the operation requires access to the server's associated data storage resource. If it does, the server accesses the resource to perform the operation, and sends a corresponding response to the client. Different servers can work on different operations specified in a request. The client receives and merges the responses from the servers. During a failure of one cluster in a multi-cluster system, the surviving cluster can process a request using the resources owned by the failed cluster.

Provided are a method, system and article of manufacture, wherein a first application and a second application are executed in a first process space in a node, wherein a third application is capable of executing in a second process space. A common interface to the first, the second, and the third applications are provided by a remote proxy class. The third application is executed in the first process space by securing a plurality of attributes for the third application from the common interface.
摘要:
A computer readable storage medium includes executable instructions, which when executed by a computer, cause the computer to designate a selected thread identification value from a collection of thread identification values based upon recognition criteria. The selected thread identification value is utilized during bidirectional text messaging between a first user and a second user.

摘要:
Provided are a method, system and article of manufacture, wherein a first application receives a message from a second application, wherein both the first application and the second application execute on a node of a network that comprises a plurality of nodes. The first application also receives an identifier corresponding to a channel over which at least one other application can communicate with the second application, wherein the channel is a logical connection at an application level. The identifier that corresponds to the channel is stored with an identity of the second application. The stored identifier is accessed to allow the at least one other application to communicate with the second application over the channel.
