I'm developing on a new .NET application that needs to read/write data from an Oracle 9i database. I've got it working with ODAC 18.104.22.168 which comes with Instant Client 11.2. I had selected this version because I had read that Oracle 12c Client was only backwards Compatible to version 10g release 2 servers. Unfortunately I can't find that reference.
I would prefer to use latest version of ODAC 12.2, but I need to confirm that I'll still be able to connect to a 9i database.
Note: All the links I found to Oracle Compatibility charts are hidden behind an Oracle registration wall that isn't currently working for new signups. So I'm asking the question here.
