Hi

I am unsure of where this would sit, so i put it here
Let me explain the situation
We are using PDA's with SQL CE installed on them, and a Windows Mobile Based application to create Quotes and Invoices
We then Synch the 'dirty' data that is one the PDA with the Database on a server through the Internet.
It connects using a Replication Publication
The problem is that I need a Generic Name for the SQL CE to Connect to (the Server) so that when that server Crashes i Can Swop to another one which is set up with the exact Name.
I don't want to have to change the Computers name and the SQL server instance name everytime something happens.

Is there anyone with a suggestion on what i might be able to do, i have tried to create alias pointing to the server but the SQL CE doesnt support that.

I have looked on Google for info and i cannot find anything of value to me

Thank you in advance

Kyle

You're pretty much describing a cluster: two or more machines configured so that if one of them crashes, the cluster fails-over to a different node. The cluster will have a single name (e.g. SQLMAIN) that references whichever of the nodes is currently active (NODEA, NODEB, etc). Check out clustering in BOL, or have a look in the High Availability forum here.

Instead of using a cluster, you could also just use a DNS alias. So the client's would point to a DNS alias and that alias would direct them to the proper location. On failover, just modify where the DNS alias is pointing to, which means you don't have to touch the clients.
