Oracle Database Configuration Assistant - Version and later
Information in this document applies to any platform.


On Linux, create database with DBCA on systems with more than 4 GB physical memory ignores memory_target and does not set up AMM in or higher version.

This is visible when the database is created in silent mode from a template, ASMM will be set even if memory_target >0. 

In interactive mode you may mark AMM at the corresponding step - it will not be marked by default.

Note: In database 12.2, you could encounter DBT-11211 when use AMM on OS whose memory > 4GB. You have to make use of ASMM instead of AMM.
