Accessing a oracle DB from web AS in a DMZ zone

Hi all,

I using a webdynpro application where the backend is a oracle system.This system is different from the server.

say the Web AS server is SYS1

and the server which has oracle as SYS2.

I have created a DB in oracle DB of SYS2 and created a SID,user etc.

When i connect to this DB from inside a network there is no problem in connecting.But i have a requirement where the webAS server (SYS1 ) is placed outside the local network we are in i.e its placed in a DMZ zone. Now when i run the applcation the data from the oracle DB is not accessible..Are there any settings in visual admn which i shud enable.(I have opened the ports 1521 and 1527 also !)

And one more point ..I am not using a datasource. I am using EJB where i am directly using the driver manager class with system ip to connect to the oracle system.

how do i solve the problem

Regards
