Hi,
i have a DB 8.1.7 on Linux. For resolution name i use local naming, and on my client I edit my tnsnames.ora standardly (sid = "sid", protocol = tcp, port= 1521).

It's all ok, I connect and there isn't any problem. But when I go to edit llistener.ora on my server I don't try it. I search it with command find, ma it isn't. After that I stop listner and I start It, this is the output prompt me:

Starting /home/oracle/OraHome1/product/8.1.7/bin/tnslsnr: please wait...

Ther isn't nothing about system parameter file.
Why? If there is, where is my listener.ora?

Thank you,
