I'm learning a little bit about Oracle Database. As I understand:
In previous versions of Oracle DB (versions <= 11ng), each DB should be installed in a separate server.
- Is this statement true? We can't create more than of one database in each instance of Oracle installation? or I'm missing something here.
To take care of the problem, oracle updated its architecture and introduced the pluggable databases.
- Why not just using the same architecture of other DBMS systems like MySQL whre you can have N number of databases in you single installation of DBMS?
I'm guessing that I'm not fully understanding the first statement as I never had any experiences with Oracle Database.
