Security issues aside (where's your firewall, would moving this tier open up a security hole, etc.), the biggest thing that I would consider before moving the application tier into Oracle is whether or not the gain of having my objects do a semi-local database connect is more beneficial to me than the performance hit I'm going to take running under the 8.1.6 Java VM.

I've posted a benchmark (
http://www.interealm.com/roby/technotes/cvsjava.html ) that shows the Oracle JVM performance is only about 20% faster than running classes under a traditional JDK 117 environment and 50% *slower* than running the same class under a JDK 1.2 environment.

Now if you classes are doing very small units of work, this may not be a concern to you. But I would really stay away from the 8.1.6 JVM if you are doing medium-large amounts of computation, query processing, etc.
