Abstract
A technique for handling failure modes which may occur during the processing of indications. In a client-server environment such as a client-server network used in computer data storage running object-oriented software, the client may subscribe for certain indications on certain objects in the servers. When the state of any of those certain objects change, an indication is fired back to the client to indicate a state change. Failures in the client, server, or connection therebetween reduce the effectiveness of this state-change notification scheme. The present invention mitigates the impact of such failures, employing a technique by which a failed storage processor in a server can failover to another storage processor in the same server to enable the seamless transition of the processing of such indications to the other processor without stopping and by which the server can destroy any of its resources that were dedicated to the processing of indications for a specific client if and when such client fails.
