A Oracle Database Cloud Schema Service Security Lockdown Implementation Considerations
The Oracle Database Cloud Schema Service is a multitenant environment, based on schema isolation. To ensure the security of each tenant's data, and the overall performance integrity of the entire Schema Service environment, some aspects of the Oracle Database, Enterprise Edition, have to be curtailed or completely eliminated.
The limitations required to protect security and performance integrity are detailed in this section. The limitations are permanent and cannot be relaxed. None of the limitations listed have been put in place as an attempt to limit the functionality of the Schema Service. Virtually all standard SQL and PL/SQL syntax and constructs used with the Oracle Database work in the Schema Service.
