Oracle 12c client connect to 9.2 DB ORA-3134

edited Oct 4, 2017 2:08AM in Database Administration (MOSC) 2 commentsAnswered ✓

I have installed Oracle 12c R2 client on a pc.

I'm trying to make sqlplus connection to 9i server and getting error ORA-3134.

I've been searching around the web and some say that it is possible and other that is not.

However I added on the client 12.2 pc under sqlnet.ora:

SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8

and still getting the same error.

Just to confirm please. Is it possible? If yes what else needs to be changed?

Thank you

Howdy, Stranger!
