sql server clustering : Setting up SQL Server in a Load balanced Active-Active configuration

In the 'normal' context of SQL Server, load balancing has no meaning.

If you are setting up an Active/Active cluster, each cluster instance will
have different resources (i.e., databases).

I suppose that you could use transactional replication to have to 'almost'
identical server/databases -but then how to direct clients since they would
have to request one instance or the other.

Nope, just doesn't make sense.

Load balancing is not available for SQL server cluster. And yes, you need
SQL Server 2000 Enterprise for clustering.

There is, however a 3rd party tool that will allow you to do this:

Resonate's product 'sounds' interesting. But the OP was about setting up
load balancing with a SQL Server Active/Active cluster. Resonate's product
does not do that.

And even with Resonate's product, there still is the issue of keeping the
databases synchronized. It has specialized uses, but clearly not for high
performance/highly reliable situations.

It was "documentation" that was relevant to the OP's question. I did
not get the impression that the original poster wanted opinion on what
was most appropriate for his/her implementation, but rather directional
documentation/ideas that could be perused to make an educated decision
regarding the deployment --and that is what I contributed. Offering
the details of what MSSQL can and cannot do is relevant, but more
importantly adding suggestions for alternatives could help engineer an
appropriate solution. Engineering the best solution is not always
black and white.

Hi
Can anyone point me to some documents details how to set up SQL Server in a
Load balanced Active-Active configuration??

We are using SQL Server 2000 (Enterprise), with Windows 2000 Advanced
Server. I don't think this is possible with Standard (??)

Thanks
