JDeveloper not able to connect after upgrade to database 12c
Dear All,
I am facing issue of making connection to database which is upgraded from 11g to 12c. Previous database version was 11.1.0.7.0 and I was using JDeveloper 10.1.3.3.0 with that. Now we upgraded to database 12.1.0.2.0 and when I tried to make a database connection to 12c I got following error:
ORA-28040: No matching authentication protocol
Do I need to use Jdeveloper 12c with database 12c or any configuration changes at client or server side are required?
