How/when are maintenance packs applied?
I am looking for information on how maintenance packs are applied. For example, I see a fix for an issue that we have that has been fixed in a 20D February 2021 maintenance pack. How do we get that fix? Are maintenance packs applied cumulatively during our regularly quarterly updates (for example we get our 21A update this month - do we also get all of the fixes by Oracle since our 20D update was applied in December)? Or do we have to request it be applied?
Any guidance and information is appreciated. Thank you!
