Automatic Data Optimization (ADO) Supports Database In-Memory Column Store in 12.2 (Doc ID 2211831.1)

Last updated on AUGUST 04, 2018

Applies to:

Oracle Database - Enterprise Edition - Version and later
Information in this document applies to any platform.


Starting in Oracle Database 12c Release 2 (12.2), ADO manages the In-Memory (IM)  column store as a new data tier.   You can create policies to evict objects from the IM column store when they degrade performance, and populate objects when they improve performance. ADO manages the IM column store using Heat Map statistics.


 Automatic Data Optimization policies can now automatically populate or remove objects from the In-memory Column Store, based on their access/usage.
