Oracle 19c Multitenant Architecture

Oracle 19c: Benefits and Features

Oracle 19c Multitenant Architecture, is the latest release of the popular relational database management system, and it comes with a powerful multitenant architecture that is designed to provide several benefits to database administrators and developers.

In this article, we will take a closer look at the Oracle 19c Multitenant Architecture, its benefits, and features.

Firstly, let’s define what a multitenant architecture is.


A multitenant architecture is an architecture that enables a single instance of a software application to serve multiple clients, or tenants.

This means that a single instance of the software can be used to provide services to several organizations or customers, each with its own data and configuration.

With Oracle 19c Multitenant Architecture, you can manage multiple pluggable databases (PDBs) within a single container database (CDB). This provides greater flexibility, scalability, and efficiency for database administrators.

Advantages of the database container

By using a single CDB, administrators can manage multiple PDBs more efficiently, reducing management overhead and operational costs.

Oracle 19c Multitenant Architecture also offers a simplified management interface. With the introduction of the Multitenant Container Database Management interface (CDBM), database administrators can manage multiple PDBs from a single location. This provides a more streamlined and intuitive way to manage multiple PDBs.

Key factor

Another benefit of Oracle 19c Multitenant Architecture is improved performance. By consolidating multiple databases onto a single instance, you can reduce resource consumption and improve overall system performance. This is achieved by sharing resources such as memory and CPU across multiple PDBs.

In addition, Multitenant Architecture in 19c, provides enhanced security features. With separate PDBs for each tenant, administrators can implement fine-grained access controls and security policies to protect sensitive data. This also makes it easier to manage security policies and apply security patches to individual PDBs.


In conclusion, Oracle 19c is a powerful feature that provides several benefits to database administrators and developers. By consolidating multiple databases onto a single instance, administrators can reduce operational costs, improve performance, and enhance security. If you’re using Oracle 19c, be sure to take advantage of this feature to maximize the efficiency and effectiveness of your database operations.
