Oc4j starting with Oracle Database & oc4j App Server on same machine

Question

Hi ALL, can anybody help me(pls read this)
This is Sagar, i have created a GIS Application(java) using Oracle 10g.
Senario I:
oc4j server and oracle 10g Database Server on different machines:
When i start oc4j server with NO. OF Mappers = 64 or 30 in DNS using
1. oc4j -start (normally)
from the path c:/oc4j/bin by setting ORACLE_HOME path normally
application is working fine but when users are increased say 4 to 5 oc4j server gives error:
java.lang.OutOfMemoryError: Java Heap Space
I searched for this error i found a solution for starting oc4j as follows:
2.Java -Xmx1024m -Xms1024m -jar oc4j.jar
from the path c:/oc4j/j2ee/home --- oc4j.jar
Then map & application works fine and fast since heap space is increased to 1GB (speed is noticable)
but if...(in other senario)
Senario II:
oc4j server and oracle 10g Database Server on same machine:
if step 2: is used form above senario, oc4j Server does not gets started only it gets initialized...(server does not gets started)
but Step 1: is used application works fine but again heap space error as mentioned above is seen.
Again if changes are made in oc4j.cmd file in c:/oc4j/bin ....by giving the heap space command oc4j works fine but the application(performance) is very very slow but heap space error is not seen.
Please can any body suggest the solution.. application should work fast and also the heap space should be increased but taking the senario - oc4j App Server & Oracle 10g Database Server on Same machine..

Hello,
How much RAM do you have on the machine? What is the size of the SGA for the database you are using?
if step 2: is used form above senario, oc4j Server does not gets started only it gets >initialized...(server does not gets started)What do you mean by this? Provide the output from the server when you start your server.
