Once I am connected to an Oracle 9 DB I  need - probably thru DBLINK - to access to some tables on another ORACLE DB located into another Oracle server.

I have done some changes in the tnsnames.ora of each server but I am probably missing something?

Can anybody help me?

No changes are required on the target (DB to connect to). Here are the steps on the source :
1/ Add the target service name to TNSNAMES.ORA
2/ Check connectivity with TNSPING
3/ Create a DB link (syntax at http://www.ss64.com/ora/link_c.html)
4/ Target tables are : <owner>.<table_name>@<db_link>

Thanks, I have checked it and it works fine.
By the way, jst before closing the issue. Shouldn't be better to add a new listener for the target server to get a better performace and security?

Nope.
You'll have to secure and monitor 2 listeners, and the second listener will waste a little bit of RAM.
The only benefit I can imagine is related to firewalls (ie if you must use specific ports between the 2 hosts)...
