Hi,
I am evaluating 12c and the concept of pdbs is quite new to me. I tried to copy some schemas and an apex application from my running 11g to a fresh installed 12c db. I had to rename my schemas by using the prefix c## to get it working. Obviously I used the CDB. This means, I have to change the usernames at some points of my plsqlcode as well.
Should I have created a PDB first? I do not intend to run multiple databases, so I think it is some useless overhead for me? On the other hand, I want to go the recommended way, as I use this database for learning purposes.
What do you think?
