Home -> Community -> Mailing Lists -> Oracle-L -> Re: DB links
If you're using the alias as the USING then the question is, how are you resolving the alias at the database server? When you connect using the alias, you're using the SQLNET.ORA and (maybe) the TNSNAMES.ORA on your client machine. When the db_link is trying to resolve the alias, it's using the same files on the server.
If you're using the DESCRIPTION as the USING then make sure that there's no blanks or non-printing characters, ie, carriage returns. It shouldn't cause a problem but in my experience it does. Also, if you're using the DESCRIPTION, there' s an upper limit to how long the string can be. I'm not sure what it is but I have had problems with using the DESCRIPTION for RAC nodes - it gets too long.

Please respond

Has anyone had trouble using a link created for just certain databases,
when
everything is set right. In other words, no reason can be seen why it
wouldn't work? We changed the global name, etc., etc. I can connect to the
database but when I create the link, then try to select from dual from
another database, it says "TNSNames cannot resolve service name". But using
the same service name, I immediately connect successfully to the database!
Driving us crazy. Any help would be greatly appreciated.
Thanks,
Mike
