Cluster DB configuration with 2 application server
Could anyone have any idea about how to configure the clustered database servers with 2 application servers (QC 9.2) which are connectable thru load balancer?
and also please advise me that, is possible / not possible.

Neither database clustering nor database mirroring has been QA'd and therefore those are not supported.
According to the picture you sent of your architecture, the database is not in a cluster mode but you have a failover system. You have an active database server and in case of problems you would be switching to server 2. However, we are not sure that QC will be able to deal 100% perfect with the switch. Anyway, this switch of servers will request that you restart QC. So, you will have to spend the same time as when you have to restart QC when DB is down. Usually when DB is unavailable for a moment, we suggest to stop QC, stop database, restart database and restart QC. But we do not have any such configuration for DB clustering.
If you need to figure out a redundancy plan, you might want to talk to our Professional Services department about it. This is out of the scope of support and since it is not QA'd nor supported I cannot further assist you.
