Editing tnsnames.ora in Linux
Posted on 2013-11-01
I am adding two entries to the tnsnames,ora file on linux server.
First there are two tnsnames.ora file:
how I determine which one to use?
another thing is when I open the file for editing with vi editor, then i hit "i" and get a warning:
-- INSERT -- W10: Warning: Changing a readonly file
than I add new entries and try to save it using :w, I get a warning "E45: 'readonly' option is set (add ! to override) "
So I try :w! to save it and get "tnsnames.ora" E212: Can't open file for writing"
Can someone tell me how do I make changes to tnsnames.ora?
I am a UNIX user and my UNIX skill don't seem to apply to Linux
