The downsides of in-place patching – and a patching lab

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

Last week a very experienced colleague called me. He had issues with an export dump taken from an Oracle 20c database importing into 19c. It failed. So this blog post is about Data Pump: The Time Zone Pitfalls.

My colleague saw this error:
