Purpose
The purpose of this document is to instruct SAP customers on how to analyse hanging situations in their HANA system.
Overview
Analyzing hanging situations.
So what constituencies a hanging situation in HANA? When we talk about a hanging situation we generally refer to a whole system wide hang, as opposed to highlighting one specific activity, ie: queries or operations. This means we are going to look at the systems conditions (performance) which leads the DB to run slowly, or not at all in some cases.
Like all other software systems, SAP HANA relies on hardware to run its processes. Even when looking at the most basic single sever, single host, we can see many areas which over lap and interact with one another, in other words, when you see a hang do not just assume the cause is all related to HANA.
