As of 1st January 2020, Oracle has announced a change to their licensing which means Real Application Clusters (RAC) are no longer included in Oracle Database Standard Edition 2 (SE2).
This means any new purchases of SE2 will no longer include RAC entitlement. Anyone who wishes to use RAC will therefore need to purchase Oracle Database Enterprise Edition (EE) and the RAC option. The same applies to Oracle Database Cloud Services, where RAC is only included with EE Extreme Performance.
For existing customers, the change applies from 19c (19.1/Release 18 to be precise) onwards. If you are currently using a version prior to this, you can still use RAC as part of your original licence entitlement at the date your TOMA/End User Agreement was signed.
If you are an existing customer with SE2 licensing who wishes to upgrade to 19c or future releases and wants to make use of RAC, you will have to purchase Enterprise Edition and RAC, or migrate your existing SE2 licenses accordingly. The alternative is to downscale your HA deployment to eliminate RAC usage.
