hi we are trying to carry out log shipping in sql server 2008 enterprise edition.problem is how to divert client traffic form primary server to secondary server once we want to use secondary server i.e when secondary server comes online. is there some command or some particular tool to divert client traffic to secondary server .
also is possible to do log shipping from 2005 to 2008 and vice versa
Thanks

The use of alias's would be the most obvious option

you can log ship from 2005 to 2008 but once you bring the secondary database online the log ship scenario is broken and would require completely restarting

Log shipping will not work from 2008 to 2005 as backup files are not backward compatible.

Suppose you use webserver connecting to DB Server.

Then you could create alias on Webserver and using it in DB connection string(SQL Server Configuration Manager->SQL Native Client->Aliases).

After the primary server down, you just only change the DB Server name to a secondery server, then the application could direct to the correct server.
