You are reading correctly: Premier Support for Oracle Database 21c extended is the headline.
Isn’t it an innovation release?
Yes, you are right. Oracle Database 21c is an innovation release only. And we boldly tell you for a longer while: Move your production estate and everything tied to it from Long Term to Long Term Support Release. This means: Bring everything to Oracle Database 19c, and then later move on to Oracle Database 23c.
An Innovation Release such as Oracle Database 21c should be fine for developments using new features but ideally not used in production since it has such short support periods, and no offering for Extended Support.
Reality is different
But we have customers being live on Oracle Database 21c, or just moving to it right now. And there are multiple reasons to do so. One of my customers, a German insurance, use the JSON features in Oracle Database 21c already. They were keen on it, and could not wait for Oracle Database 23c. Well, and to be frank, Oracle Database 23c on-prem is not available at the moment I write this.
Or another customer we work with needs Oracle Sharding features which are not in Oracle Database 19c but in 21c.
So, there are reasons. And reality sometimes dictates different rules.
Oracle Database 21c Premier Support
Originally, the Premier Support for Oracle Database 21c was supposed to end at the end of April 2024. But since Oracle Database 23c is not available yet, and even when it will be available before this date, the time to move to 23c would be very short.
Hence, we announce now the extension of the Premier Support for Oracle Database 21c until end of April 2025.
