I've noticed that during an installation of Oracle 12c with a container database (A.K.A multitenant), DBCA doesn't allow deselecting database options and force you to install all the optional database options.
I tried to figure if there's a workaround for this behaviour (DBCA 12.1.0.2 doesn't allow deselect database options) but it seems like it's by design and there's no workaround.
I think it would be nice if Oracle will allow deselecting database options because the design has a few disadvantages:
- It makes the installation process much longer
- It consumes more disk space
- Installing unneeded database options may raise the chances to hit potential bugs.
