You didn't say where the 9.2 database is located. It's not on the same = server as your 8.0 database is it? Check the TNS names entry for the = target database (8.0) on the (9.2) server. The entry may not exist or = is incorrect. If you search the archives of the list there is a lot of = info about db links. I find them troublesome also. My cube neighbor is = trying to hunt down the same problem <g>.

I can do this via sql*plus, but no luck when using a database link. I have an 8.1 database on the same server as the 8.0 database and can connect via a db link and sqlplus. I have looked at Metalink and found an article that is pretty straight forward. I don't have my connections 'fully qualified' but the connections are set up the same and one works and one doesn't. When you use a link does it use the 'listener' where the database resides and where the connection is coming from? This is probably a dumb question but at this point I am questioning everything I think I know about it. Any guidance??
