I am an educator and teach Oracle Database 12 c. I have the following problems which I humbly request the community to help on;
After creating a PDB ( pluggable database) I created a Local User with tablespaces. However, when I try to connect with local user after granting them DBA, it refuses to connect with this user. I tried this several times and even checked my ORA and TN names files are OK. Could you please assist.
