Our company is planning to have 2 HUB's ( WIN 2000) servers which will be separated Geographically i.e planning for a Geographic clustering. My question is can we achieve a real fall over for Geographic clustering for MQ, DB2 and WBI . If Geographic clustering is possible can anyone point me to a good documentation which will help us to implement.
thanks

I doubt the network will be 100MB all the way between the hubs.
MQ can provide fail-over using clusters but messages in the failing queue manager will get lost or be stuck there until the QM is up again.
DB2 will have fail-over capabilities, but may be not for Windows.
If you have all the flows on both brokers, there is no problem there. With seperate brokers you also need the working directory to fail-over.
So for a sound fail-over system you have to look at Windows clustering and storage mirroring software.

DB2 8.2 has also added HADR, which is very simple to setup (through a wizard believe it or not). HADR differs from replication in that it is a simple mirror of the database, there can only be one primary at a time - but it is very easy to setup.
