Oracle JVM problems

Dear DBA's,  

Hi there all, we are running MTS for the oracle auroara (java VM), first = of all I can not get EJB's (enterprise java beans) run without using MTS = for iiop connections to the oracle JVM, if anyone has it would be great = to hear from you :) also, running utl stats during some testing, we = find the oracle server kill the CPU, it seems that the MTS servers are = working like crazy to manage our simulated 100+ concurrent connections. = Here is an extract from the report.txt  

Event Name                       Count         Total Time    Avg Time    =

Can anyone give me some clear cut direction on tuning mts servers and = dispatchers? as these stats tend to point to some major mts problems.

Also, given this in the init.ora

mts_dispatchers = =
"(PROTOCOL=TCP)(PRE=oracle.aurora.server.SGiopServer)"

how can I translate this BACK to a dedicated server config? does a = dedicated connection work for iiop requests?  

Cheers  

Chris.
