By | Database Administration & Monitoring | No Comments

In a previous blog I talked about protecting data using Realms. With Database Vault we can also protect our database against some SQL statements.

Oracle Virtual Private Database

By | Database Administration & Monitoring | No Comments

Oracle Virtual Private Database (VPD) enables you to dynamically add a WHERE clause in any SQL statement that a user executes.

Oracle 12c: Applying PSU 12.1.0.1.1 with Multitenant DB & unplug/plug

By | Database management | No Comments

The concept of Multitenant databases, which was introduced with Oracle 12c in June 2013, allows to run several databases on a single instance. Oracle presents this feature as a good solution for Oracle patching. The reason behind it is that it is now possible to unplug a container database (called PDB) from its original container (called CDB), in order to plug it into a new local or remote Container with a higher level of PSU….
