So far as I understand the 3 tiers are
Web server(Say Apache/IIS)
Application server(Say Tomcat/Weblogic).
Database server(Say MySql/Oracle).
Am I correct?
I also have seen Tuxedo middle tier to be used with oracle.

No, the 2nd tier is where the business logic is. Usually you haev something call App Servers (like WebLogic, etc). The 3rd tier is where the datastore/database is. Middleware is not considered part of the 3tier architecture. It's more like a broker that goes in between different applications.
