Currently, I have a very good experience with Oracle Multitenant. The pluggable database is easy to handle and manage, sharing resources efficiently. However, Oracle license pricing is an issue due to its high cost. Our organization is compelled to reduce CPU usage by seventy CPUs because the Oracle license cost depends on it. View full review »

There are many functions where changes are not easy to implement, and we try to avoid modifying these areas due to security issues and the complexity of maintaining them. Also, support can be improved as it sometimes takes a long time to resolve complex issues.

Everything is going well with the tool. From the scope of improvement, I would say that people are adopting new query options. Certain databases like MongoDB adopt new query options so that they can just pull the data. Using new query options, we can generate the data, which will be pretty helpful for those users who don't have any knowledge about databases. They also can face the data without learning to do some queries.

I think a GUI for commands would improve the solution because it's currently managed with commands in the CLI.

I have not encountered challenges that require feedback for changes. Oracle Multitenant is quite stable and reliable. The only issue is that shared files for the main container affect all container databases if something happens to them.

There is room for improvement in customer service and support.

Technical support could be faster. 

It's a nice product. It rarely disappoints anyone, but when it disappoints, support takes a lot, a bit of time before they sort you out. If they could improve that, then it'll be a very good experience using it.

In terms of what can be improved, the interface is ok. I don't know what can be better. I don't see any problem. 

I would say that the portable database should not be open as the default. That causes you to lose time.

I would also like to see an easier way to give answers when I'm working, but I think that is more about my understanding of how to work the container database. This solution is a bit complicated when collecting from containers - that feature should be a bit better.

It would be beneficial to include this solution with Oracle Enterprise, but Oracle charges additional fees for it.

I'm not using it in production yet. It's easy to test a product. You can test it, play with it, and use the trial, but to put it into production is another story. 

That said, Oracle, in general, doesn't invest in their UI for any of their applications. If we're talking about the dashboard or other user experience, there is room for improvement. I'm talking about on-premises. The cloud version has started to improve.

The user interface for this solution can be made better.

This solution is a little bit pricey. It costs a lot of money.

I can't think of anything right now, I've been pretty content with what we have.

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

Even though we say Unplug Plug Upgrade is a very good feature and it does work, we are seeing that sometimes it takes longer than what we expect for larger databases. Secondly, it does have that prerequisite of first upgrading in place to 12, and then you migrate. If you have a lot of non-multitenant databases as a source, the process of making them into multi-tenant databases is sometimes a bit longer and tedious, especially if you are at the pre-12c version. That's the only place where I would see if they can directly convert maybe an 11g database to pluggable 12c. That would be great. Right now, we are upgrading in place to 12c, non-multitenant, and then making it ready for the plug in.

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 database doesn’t exist. Another important feature will be to support multiple character sets in one Multitenant database.

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

Multitenant is just at the beginning in 12c R1. More features have been announced for the next generation, such as the online unplug/plug. That goes far beyond what transportable tablespaces do because they require the source to be read-only.

Oracle has a lot of work to do with Multitenant because it's a new feature. For example, it prevents you from actually using it if your database has certain features that it doesn't yet support. We'll have to wait and see if the next release fixes some of these issues.

While the product is overall excellent, it is quite expensive.
