Oracle Release Schedule of Current Database Releases
- Oracle Database 21c, also available for production use today as an innovation release, provides an early insight into the many enhancements and new capabilities.
- Oracle Database 19c is the current long term release, and it provides the highest level of release stability and longest time-frame for support and bug fixes.
Let us start:-
Oracle has two types of Oracle Database releases
- Long Term Release
- Innovation Release
Long Term Release:-
Oracle Database Long Term Releases are ideal for use cases that benefit from less frequent upgrades to newer releases. Long Term Releases offer the highest level of stability and the longest length of error correction support. These releases have 5 years of Premier Support followed by 3 years of Extended Support. When combined with Extended Support, customers typically have almost 4 years to upgrade from one Long Term Release to the next Long Term Release.
Innovation Release:-
In between Oracle Database Long Term Releases, Oracle delivers Oracle Database Innovation Releases that include many enhancements and new capabilities which will also be included in the next Long Term Release. Innovation Releases are designed to enable customers to continuously use leading-edge technologies to rapidly develop or deploy new applications or augment existing applications. Support for Innovation Releases includes at least 2 years of Premier Support, but there is no Extended Support. Production workloads can be deployed on Innovation Releases if upgrading to the next database release within one year after the next database release ships is factored into the deployment plan.
Error Correction / Patching is available until April 30, 2024
21c is not eligible for Extended Support (ES)
Only quarterly Release Updates (RUs) are provided for 21c. Release Update Revisions (RURs) are limited to Long Term Releases
21c is not available with Exadata Database Service
Oracle have announced there will be no 22c release, so the next release after 21c will be 23c, which will be the next long term release.
If you are on 19c than you need to wait until 23c is released
