Mirroring on 2 windows servers with the same instance name on each server

Hi

Please can anyone tell me if there are issues with creating mirrored SQL Server 2008 R2 instances that have the same instance name?

I have been asked to create the following;

Server1\Instance1 mirrored to Server2\Instance1
Server3\Instance2 mirrored to Server2\Instance2
Server4\Instance3 mirrored to Server2\Instance3

In addition, another instance will be installed on server2 for logshipping purposes from the production servers.

Other than any potential impact with IO/networking etc - are there any issues with doing this?

Many thanks for your help

Please use the built-in replication option available from the Studio manager.

Hi

Are you saying that I should not use mirroring then?

The business took the decision to do their DR using mirroring and log shipping. Not replication.

Thanks - That is a great document and I hadnt seen it as yet.

My original question still wasnt answered in it though - would it be a problem if the mirror and secondary instances had the same name?

(This is so when they fail over, the applications only need very minor changes to swap them to the secondary db)

I suspect that the lack of a warning about doing this implies it is okay (which seems to be ms's way), but I would really appreciate knowing if anyone has done this sucessfully or not.

Many thanks,
Sue

Thanks for your help - its working fine with the matching instance names - though it does make me check a lot more that Im in the correct instance when I do things!!
