DMZ and Database issues

[LeGuru]

Hi everyone,

I have a little problem and i need some advice.

We are soon installing two new webservers in our DMZ.
The Webservers will be in contact with a Oracle database.

We have some architecture issues with security here our 2 options :

OPTION 1:
Firewall ---> DMZ (Webservers) --->Firewall---> Inverse Proxy----> DMZ 2(Small Oracle database) <-- Firewall <----LAN

OPTION 2:
FIrewall ----> DMZ (Webservers)----> Inverse Proxy --->Firewall <----> LAN (Central oracle DATABASE)

With option number are we gonna have to consider the replication issues and some performance problems ?
With option number two is there a way to make it really secure ?

For now i know that option #1 is really simple.

Any suggestions are welcome.

Thank you !!

PS: Data needed for the webservers is not critical.
