A lot companies consolidates databases into one appliance – like for example Oracle Exadata. So you can have a lot of different databases in one physical cluster. And what if I tell you that you can execute any OS command as an oracle user, having just access to a database user with appropriate privileges? What if I tell you that DBA=SYSDBA? And not just SYSDBA for one database but for every database in a cluster?
