Hello People,

I need your help in centralizing my tnsnames.ora and sqlbet.ora files. This is what I have done on Windows 2000 OS. I am an Oracle Clinical guy and not an Oracle Expert, hence the request.

Part_1
1. Installed Oracle 9i 9.2 database on Win2K server - W2kOCSVR
2. Installed Oracle Clinical 4.5 and created DB on W2KOCSVR.
3. Started up database and all is fine - tnsnames and sqlnet.ora
4. Each of these is on a separate partition including the OS.

Part-II
1. Installed Oracle Appl Server 9iAs 1.0.2.2.2a on another machine OCMIDTIER. This installed Oracle iSuites home and stuff.
2. Then I installed Oracle 9i developer suite - Oracle forms and reports.
3. Installed Jinitiator 1.1.8.24 on the middle tier machine.
4. Basically this is the middle tier that is a Webserver that will be linked to the Database Server in Part-I

and lastly, I will have web clients with Jinitiator and a web browser.

Requirement:

I need to centralize the TNSNAMES.ora file and the SQLNET.ora file on all the machines. How do I do this?.

I have the TNSNAMES.ora and the SQLNET.ora on DB server and it is working fine. However, I have noticed many tsnnames.ora files on the middle tier - OCMIDTIER. (I've left out the example files)
a) E:\ORACLE\806\net80\admin\tnsnames.ora
b) E:\ORACLE\806\net80\tnsapi\tnsnames.ora
c) E:\ORACLE\iSuites\hs\admin\tnsnames.ora
d) E:\ORACLE\iSuites\network\admin\tnsnames.ora

All I need to know is which if these files do I need to integrate with the Tnsnames.ora file on the DB server - W2kOCSVR and how do I go about doing this?.

If the TNSNAMEs.ora files need to be displayed, I can do so. I presume Oracle Application Server experts must be familiar with what I am working with and how to do this. I appreciate your help in this venture. Thank you in advance.
