PROBLEM TO BE SOLVED: To provide techniques of retaining a state across network failures and server failovers.SOLUTION: In a software environment 200, a persistent handle is requested by a client 202, 204 after a session has been established with a file server. The request for the persistent handle includes a handle identifier generated by the client. The server uses the handle identifier to associate with state information. When there is a network failure or a server failover and a reconnection to the client, the handle identifier is used to identify replayed requests that, if replayed, creates an inconsistent state on the server. The replayed requests are then appropriately handled.SELECTED DRAWING: Figure 2 |
