Re: What's net got do with it

Thanks for the reply Joel,

I am somewhat familiar with the TNS stack. I have read through the documentation and can not find anything pertinent to my question. For example, the Oracle9i Net Services Administrator's Guide says: "The primary function of Oracle Net is to establish and maintain connections between a client application and an Oracle database server."

But I am not calling FROM a client TO the database server. I am calling FROM the database server ( which is functioning as a client) to a NON TNS application, namely an apache web server.

So, I'm still at a loss for why TNS should come into play when the target server knows nothing about TNS. Could it be that Oracle Network (TNS) is behaving as a proxy?
