Why is this important?

At first, you may ask yourself: Why should I care? And you are right. This is normally nothing you should care about. …

Happy New Year to all of you at first. I hope you all had a good start – and for myself, I promise to blog a bit more again in 2024. Let me start with my first post since I received a question very often: Why should I patch out-of-place with a new Oracle Home? Since I need to patch a bit today I can easily show the downsides of in-place patching – and a patching lab.

It all started at OCW 2023
