How to update 12c?

in Database Install/Upgrade/Opatch (MOSC) 7 commentsAnswered ✓

Hi,

I'm pretty new to Oracle.

Our company have an Oracle 12c database running which hasn't received any security updates for years. Simply because nobody knew about it and the person who knew didn't care :(

Now I was asked to fix this... I know some things about Microsoft SQL and MySQL/MariaDB but not about Oracle. So I'm pretty overwhelmed :(

I managed to get an Support Identifier so I'm able to download updates but I don't understand what patches I need to download.

At the moment this items are installed according to the "Universal Installer":

How can I update to the latest version of 12c? What patches do I need to download? Are there any things I have to take care of (need a backup first of course)? Is there a document describing the update process?

Howdy, Stranger!
