As I understand the theory of automated failover, you backup a primary server with a secondary standby server that monitors the pulse-beat of the primary and automatically takes over when the primary server fails. My question is if the primary server is performing a search and experiences a hardware failure that stops the search from being completed does the standby server complete that search, or does it just pickup the next task intended for the failed server.

Thanks. We'll let you know when a new response is added.

It would depend on the service which you are clustering, but typically the failed transaction would be rolled back, and the next command would then be picked up by the database server.

Mr Denny, could you explain your statement, “the failed transaction would be rolled back, and the next command would be picked up by the database server”. Does this mean the transaction that was in process when the failure occured gets completed by the server failed over to or is that transation lost, and the server failed over too, picks up the next transaction.

I am really trying to determine if a failover does or does not have an impact on the people using the neywork. Is a failover the same as a failure prevented from failing, or did the failure cause a transaction not to be completed? Jim4522
