问题:

I am not able to find any information on if an Oracle 12c client is going to be able to connect to a Oracle 10.1.0.5 server installation (on a diffrent machine). Both in a Windows enviroment.

Does anyone have information on this?

回答1:

As mentioned in the documentation, note 207303.1 on the Oracle Support site has an interoperability matrix between client and server versions. That says that the 12c client is not supported with a 10.1 server, and indeed that connections will error. (You'll need to look at the note for details as information from MOS shouldn't be shared; I think this is generic enough to get away with...).

Even for supported versions, you'll need to test that everything you do does work - supported doesn't necessarily mean there are no known issues, but should mean that anything you find can be investigated and fixed (or worked around) by Oracle Support.

You maay use the sqlnet.ora parameter SQLNET.ALLOWED_LOGON_VERSION_CLIENT . Please see " https://docs.oracle.com/database/121/NETRF/sqlnet.htm#NETRF2010 "
