Sometimes people have the desire to remove options from the database kernel (i.e. from the oracle executable).
It’s a matter of fact that by default you’ll get plenty of things linked into your kernel in Oracle Database 12c.

Anyhow, ideally you’ll do these changes before you create a database directly after the installation has been completed. See the documentation for Post Installation Tasks first:
