Oracle Database Administration from Zero to Hero - Managing Database Memory (Part 1 of 2)

This video tutorial covers Oracle Database memory management methods, including Automatic Memory Management (AMM), Automatic Shared Memory Management (ASMM), and manual memory management. It explains how to configure each method, their limitations, and practical implementation steps. AMM is limited to systems with 4GB or less, while ASMM is recommended for production databases. The tutorial also discusses parameters like MEMORY TARGET, SGA TARGET, and PGA AGGREGATE TARGET, and provides best practices for setting these parameters.

What are the three mechanisms provided by Oracle Database to set its memory area sizes?

Explain how Automatic Memory Management (AMM) works in Oracle Database.

How does the database decide the allocation of memory between SGA and PGA in AMM?

What happens if the total memory available for the database exceeds 4GB in relation to AMM?

What is the significance of the MEMORY TARGET parameter in AMM?

Explain the difference between the parameters SGA TARGET and PGA AGGREGATE TARGET.

What is the role of the MEMORY Max TARGET parameter?

Describe the process to enable Automatic Shared Memory Management (ASMM).

What is the practical recommendation regarding the PGA AGGREGATE LIMIT parameter?

What are the steps to disable AMM and enable ASMM?
