I have installed Oracle database Version 12.2 and "Toad for Oracle 12.1" on my new PC with MS Windows 10. I've also transferred the Toad license from my Old PC to the new PC and added Oracle_HOME (i.e. C:\oracle\product\12.2.0\dbhome_1) to the PATH of the environment variables. But I keep receiving the following error while trying to connect to the database:
ORA-03134: Connections to this server version are no longer supported.
What is the resolution to fix this problem? If there is none, how can I get around the problem. I have used Toad for Oracle on a daily basis since 2008 with valid renewal maintenance contract each year until June, 2015, and I have continued using Toad. Toad for Oracle 12.1 is the latest version on my old PC and I now have to make Toad available on my new PC.
I am desperately in need of help on this. Any and all the help on this would be greatly appreciated.
Thanks millions in advance.
