Hi all,

I can find tnsnames.ora (NT4.0 Oracle 8.0.5.2.1) under

oracle_home/net80/admin and oracle_home/network/admin

what is the different between those two.

I have service name , when I tried to user tnsping ErpUser and it failed. But I can connect plus80 internal/password@ErpUser to connect to my prod. DB.

Why tnsping not working? Why we have two tnsnames.ora file under different directory?

Thank you!
