When are Oracle Release Update and Release Update Revision released? What is the schedule for RU and RUR? It’s the same as for CPU.
It’s important to know that the patch cycle that produces Release Updates (RU) and Release Update Revisions (RUR) actually is the quarterly Critical Patch Update (CPU) Program for database version 12.2 and beyond.
Thus, the release dates of the CPU Program apply to the RU/RUR cycle as well. Small fact, big effect on searching the web. 🙂
So, as of today, the information in question is:
“They are released on the Tuesday closest to the 17th day of January, April, July and October.”
