How has it helped my organization?

Database development along several parallel projects used to be nightmarish when trying to keep the various tracks of development separate in a single database. With this… more»

What needs improvement?

The ability to integrate with every feature of Oracle Database as, for example, it doesn't currently work with Audit Vault.

What's my experience with pricing, setup cost, and licensing?

Since there is no additional cost for one PDB in a CDB, you should always create a single PDB in a CDB even if you plan on using only only one database. This allows you to… more»

Which solution did I use previously and why did I switch?

We used to use virtual machines. However, in VMs, we couldn't allocate resources dynamically and resources (CPUs, memory, etc.) are fixed at creation time regardless of… more»

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… more»

What needs improvement?

The main area for improvement is regarding backup and recovery. Today, it’s difficult to set a pluggable database to a former point in time because flashback pluggable… more»

What's my experience with pricing, setup cost, and licensing?

Oracle needs to increase the implementation rate and really allow their customers to get some benefit. I would like to allow a maximum of four or five PDBs per CDB for… more»

Which solution did I use previously and why did I switch?

Some of my customers are using virtualization (mainly VMware), while others are running up to 20 databases on one server. Two of them have consolidated their schemas into… more»

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… more»

What needs improvement?

It needs to have some more granular control over IO resource allocation.

It naturally aligns with other Oracle product so there was no need to evaluate other products.

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>
