This time a specific Oracle 12c database event at Oracle uk.
This included varous upgrade scenarios including the fact that upgrades are done in upgrade mode which is similar to mount mode where the datafiles are NOT touched, only system catalogs.
This also covered using data guard to reduce downtime during upgrades and using Goldengate which can even replicate between very old versions and the later versions to reduce downtime during upgrades.
Interesting event with eDBA on August 7 covering Oracle 12c 188.8.131.52 which adds in-memory features.
This Oracle in-memory offering is columar and NOT persisted on disk, instead a new memory area is used to store the in-memory version of data.
