Quick note on MT and applications

Are you using multi tenant with multiple containers and you’re not familiar with application containers?

It allows you to set up PDBs that belong to a CDB-like PDB that “owns” them. With that you can install applications (database objects) in the container, and then decide into which PDB to install, upgrade or patch that particular application,

So you could have an application that is a set of schemas with objects that belong together in a logical sense. Once you have the application created in the application container, you can go to an PDB and sync that application there to get it to the latest version.

It is a very nice feature you should take a look at if you are licensed for the multi tenant option. I like to think of this feature as kind of “EBR light”. It is for sure not a full EBR, but it is a very neat feature to install the next version in the application container, verify it there before you sync it into your PDB where the system is actually running.

Start with the Oracle documentation.
