Last updated on MARCH 19, 2018

Applies to:

Oracle Database Configuration Assistant - Version 11.2.0.3 to 12.2.0.1 [Release 11.2 to 12.2]
Linux x86-64
***Checked for relevance on 18-Apr-2017***

Symptoms

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 11.2.0.3 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.
