Oracle Linux 7 was released in 2014 and the system is close to its sunset. The premier support for the system will be wrapped up by July 2024 and it is time to think about moving forward. All the new systems, as I can see, are using version 8 and some even version 9. So it is time for an upgrade. And when we speak about upgrading we usually have two options – in-place and out-of-place. The in-place upgrade modifies the system on the same box keeping all the users data intact and the second approach is more like a migration when you move all your app stack and data to a new box with a new version of the OS. So, how difficult is the in-place upgrade and when it makes sense?Continue reading “Oracle Linux in-place upgrade. Good, bad and the cloud. #JoelKallmanDay”

Moving Oracle database to the cloud. 12.2 standalone to 19C RAC PDB.
I see more and more Oracle databases are moving to the public cloud or to a hybrid cloud solution. Depending on the platform, size and used options it could be a different path but the general approach boils down to three main options – Oracle RMAN backup and restore, Oracle Data Guard or Oracle Data Pump with or without transportable tablespaces. Here I want to share our approach for migration from 12.2 standalone database to 19c RAC container as PDB in the Oracle Cloud Infrastructure (OCI).Continue reading “Moving Oracle database to the cloud. 12.2 standalone to 19C RAC PDB.”
