Look Al: you were told in the first post that it's sort of like a DNS server. That it resolves service names into host:port:sid addresses so that the Client doesn't have to do that for itself using a tnsnames file.

How much more information do you need to determine whether it will be "helpful" for Heaven's sake? Is DNS "helpful" for a home network? Probably not. Is it helpful when resolving Internet IP addresses by the million? Yes. Same with Names Server. You got 1000 client PCs? It will be helpful. You got 10? It probably is more hassle than it's worth.

No. What you have gone on to ask is *details* about not just Names Server but the entire Net8 architecture (like "where does sqlnet.ora reside?"). And it is no purpose of the newsgroups to substitute for reading the supplied documentation where such detail (and the principles underlying them) is explained at great length. You had the answer to "would it be helpful" way back in reply 1.

If you found my answer rude, well, I'm sorry about that. I don't try to be. As you point out, I did actually answer your question about just what sqlnet.ora does and doesn't do. What I suspect you found offensive is the bit where I remind you that documentation isn't a nice added extra, but an integral part of assessing whether something is practical and useful. I still believe that to be the case, and getting you to read it is as much offering help as anything that can be posted here by anyone.

If there are bits of the documentation that make no sense, or that raise further questions in your mind, fair enough. That's exactly what this newsgroup is all about.
