SAP HANA – Detailed Memory Analysis Walkthrough

Introduction

In this exercise, I’ll give a walkthrough on how to perform a top down investigation on high & peak HANA memory usage and its associate top memory consumers with the aid of HANA SQL scripts attached to SAP Note 1969700 – SQL Statement Collection for SAP HANA and Statistics data (History / Current) collected by ESS / SSS (Mandatory. Recommended retention = 49 days)

I’m taking below example where I was asked to perform a memory analysis on a productive system where there was a spike of peak memory usage, around 5.9TB.

Demystifying SAP HANA Administration

Since its release, SAP HANA represented a radical change in the direction of SAP's product architecture. As an SAP Instructor, I’ve been wondering how easy it would be to manage the new SAP HANA platform. Can I use platform and administration tools that are currently in place? Or, do I need to learn a new set of gadgets?

After reading through some of the documentation available in SAP Learning Hub, and reviewing SAP courses such as SAP HANA Introduction (HA100), SAP HANA - Operations & Administration (HA200), and SAP HANA Implementation and Modeling (HA300), I realized that the learning curve is quite easy – if you get some guidance up-front. That’s why I’m here! This blog will demystify SAP HANA administration by listing tools you can use to handle periodic administrative tasks, and by explaining the key capabilities of each and when to use them.
