datapatch stores rollback patching files in the database

I held back this blog post for a longer while. A customer (Thanks Jannes!) reported this to me many months ago but the fix was not as trivial as we thought initially, and there were several unlucky circumstances delaying it multiple times. But now it is time to tell you how datapatch stores rollback patching files in the database. And of course, how to cleanup.

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. …

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

Ok, we didn’t really start it at OCW 2023 in

Patching to Oracle 19.19.0 out-of-place with additional patches

From all my quarterly blog posts you know that I patch usually in-place for space and other reasons. And you may have similar reasons when you patch. But it is not ideal – and just speaking about risk and downtime, you should always patch out-of-place. So let me show you how Patching to Oracle 19.19.0 out-of-place with additional patches works.

What do I need?

Actually, this is not complicated at all. And if you never done it this way, give it a try now please.

Some additional information regarding the Oracle 19.14.0 RUs

You may have read my previous blog post about patching all my environments to the January 2022 patch bundles. But since I do this in a very simple non-RAC, non-GI environment, I may not see issues you may have encountered. Some people commented – and I would like to share Some additional information regarding the Oracle 19.14.0 RUs . Still, please, this is NOT a collection of all open issues. I just see this blog post as a summary of the issues I have seen and/or heard about so far.

Out-of-place Patching

When you patch out-of-place with a new home – which is clearly our recommendation – you may see another tiny pitfall with DBMS_OPTIM_BUNDLE.

When you check DBA_DIRECTORIES, you will find two directories being related to DBMS_OPTIM_BUNDLE.

SQL> select directory_name, directory_path from dba_directories where directory_name like '%OPTIM%'

DIRECTORY_NAME	     DIRECTORY_PATH
-------------------- --------------------------------------------------
DBMS_OPTIM_LOGDIR    /u01/app/oracle/product/19/cfgtoollogs
DBMS_OPTIM_ADMINDIR  /u01/app/oracle/product/19/rdbms/admin

You see the “19” in the …
