Apache and Jserv

Hi,
I have 3 servers : 1 - Database 1 - Apache Server (IAS) 1 - Jserv

Currently, I can successfully connect Portal and log in to the database using portal30. But one question is How do I configure my Apache Server so that it will use the mod_jserv to connect to the Jserv in another Server ?

As what I did I edit the jserv.conf at the Apache Server and add in several lines as below

ApJServManual on
ApjServDefaultProtocol ajpv12

ApJServShmFile logs/jserv_shm
ApJServBalance set1 JVM1

ApJServHost JVM1 ajpv12://:

ApJServRoute JS1 JVM1

ApJServMount /root balance://set1/root
ApJServMount /servlets balance://set1/root
ApjServMount /servlet balance://set1/root

Question 1 : Is this the correct setting for this type of architecture ?
Question 2 : How do I know I pointing to Jserv successfully ?

Question 3 : How do I disable the Jserv in the Apache Server? Is it ApjServManual = On in the jserv.conf or else how ?

Question 4 : How do I disable all the services in the Jserv Server except the Jserv ? I installed the Http Listener from Oracle Database CD.

Thanks! Your reply is very much appreciated!
