Editing tnsnames.ora in Linux

I am adding two entries to the tnsnames,ora file on linux server.

First there are two tnsnames.ora file:

/u01/app/oracle/product/11.1.0/client_1/network/admin/tnsnames.ora
/u01/app/oracle/product/11.2.0/network/admin/tnsnames.ora

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

Did you try to ls -l these file location

/u01/app/oracle/product/11.1.0/client_1/network/admin/tnsnames.ora
/u01/app/oracle/product/11.2.0/network/admin/tnsnames.ora

You need to change the file for editing

chmod 777 /u01/app/oracle/product/11.2.0/network/admin/tnsnames.ora

then try to edit it save it and change the permission back.


If that does not work you can always su to root.

first of all, seems you have multiple oracle versions installed either client for 11.1 and 11.2 or client/server different versions.  need to edit the one that matches the sqlplus version

second, don't make the file world-writeable.  edit the file properly with the oracle account (or whatever account owns it).  changing things like that to world-writeable is asinine and unnecessary
