Hi there:

I have 2 nodes Active/Passive cluster on Windows 2008 R2. MSDTC was configured as a clustered DTC. If everything is set up correctly, shall MSDTC Drive (M drive) and Quorum drive (R drive) be online on the source and the target server? Or they should be online on the source and offline on the target server?

what if I don't use distributed queries, can I ignore MSDTC part and the FAILOVER/FAILBACK still works?

Think they are online on the active only.
Yes - you don't need to configure DTC - but I think that will impact some dev tools if you don't.

Are ou sure you want active passive - muli instance is just as easy, you just have to be careful that you don't you more than a full server of resources with the total.
Also make it easier to add another server and have more redundancy.

Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

Thank you for the reply. Eventually, I will set up Active/Active. We have SQL 2008 standard Edition and that supports two nodes cluster only.
For now, it is Active/Passive. The source server is on production that was set up by somebody else, but I just found out the MSDTC CIDs are the same on the two nodes server. I am trying to fix the problem without rebooting the source server. So far, I have no luck. That's why I am thinking to ignore MSDTC part.

You mentioned multi instances, do you mean multiple instances on one node or on multiple nodes? Can I setup multiple instances on one node and not useing more than a full server of resourses with the total. Sorry, I am new to the Windows cluster.
