Oracle Database as our consultants live it every day: installation and patching, upgrades, RMAN backup and recovery, Data Guard, RAC, performance tuning, multitenant, licensing, and engineered systems such as ODA and Exadata.
We know that during the ODA patching, a new grid version will be installed. To avoid the /u01 file system to fill up, we need to cleanup the old version. In this blog, I will show you how you can do it and also few changes coming with version 19.29, as you might need a reboot before. Remember that until…
I had to recently patch several ODAs from 19.28 to 19.30, and one ODA patching failed running the prepatch report which is mandatory and helpful before going to patch the ODA. For each step (server, grid or storage) a prepatch report is needed. I had to troubleshoot and I could solve the problem, and I thought it would be more…

The GoldenGate migration utility provided by Oracle allows you to quickly upgrade your classic architecture into GoldenGate 26ai with Microservices Architecture. But even after some updates, it still has a few bugs, as I explained in a previous blog post. One of them can lead to an OGG-15409 error during the migration. This error will not appear when running the…
CIS recommendations The Center for Internet Security publishes the “CIS Oracle database 19c Benchmark” with recommendations to enhance the security of Oracle databases. One type of recommendations is to remove grant execute to public (chapter 5.1.1.1-5.1.1.7 Public Privileges). There is a list of powerful SYS packages.

Usually, it happens when following the official documentation instructions for patching. They…
