What is Oracle Multitenant?

Oracle Multitenant - an Oracle Database 12c Enterprise Edition option – introduces a new architecture that enables customers to easily consolidate multiple databases, without changing their applications. This new architecture delivers all the benefits of managing many databases as one, yet retains the isolation and resource prioritization of separate databases. In addition, Oracle Multitenant enables rapid provisioning and upgrades, and fully complements other options including Oracle Real Application Clusters and Active Data Guard. p>

DBA at a tech services company with 501-1,000 employees

Streamlines the cloning of databases and environments for us, takes half the time

What other advice do I have?

It's a pretty good product. Go for it.
Principal Global Database Architect at a leisure / travel company with 1,001-5,000 employees
We can reallocate resources among databases as needed, dynamically, without restarting.

What other advice do I have?

Definitely consider this for non-production databases. Create multiple PDBs for development, QA, etc. which lets you test multiple projects in their own independent environments without additional CPU, memory or storage.

Manager - Oracle Apps DBA and SAP BASIS support at a tech vendor with 10,001+ employees
We are using it for consolidation projects. We no longer have to co-locate databases on servers and create a lot of VMs.

What other advice do I have?

Go for this. As far as this product is concerned, we are happy with this product. Definitely, if you solve the licensing part of it, the product, capability-wise and features, is phenomenal. There's no question about that. I would wholeheartedly recommend this product to anyone.
Managing Director at CarajanDB
It’s easy to clone an existing database in the same CDB into another CDB running on premise. ​The main area for improvement is regarding backup and recovery.

What other advice do I have?

You need to test it. It takes some time to get familiar with the functionality, but then you will see how beneficial the option is. A DBA will save a lot of time managing databases – even more because with Multitenant it’s easy to define Application DBAs so that you can offload the nasty parts, like user management or tablespace management to the application owner.

I have found that its top-down approach from container database to the pluggable database is seamless, logical and gets aligned to business rules pretty easily.

What other advice do I have?

Test and test it again. Make sure it aligns with business rules.

Offers better isolation of namespaces, resources and credentials.

What other advice do I have?

You need to learn what changes are needed with multitenant architecture. Start to use it on a test database.
