Finding evacuation paths under real wildfire conditions – an application of SAP HANA graph and spatial

Motivation

Global warming is affecting the temperature, precipitation levels, and soil moisture of our forest, turning them into kindling during wildfire season. To exemplify the severity of the problem, the 2018 wildfire season in the State of California USA was the most destructive and deadliest recorded thus far, with over 7500 fires burning an area of over 1,670,000 acres.

SAP HANA of Persistent Memory using Intel’s DCPM or IBM’s vPMEM

In late 2018, when I first read this whitepaper on SAP HANA Adoption of Non-Volatile Memory it kept me hooked on Persistent Memory technology and its usage with HANA. Ever since then, I regularly followed the announcement of this persistent memory technology and on 2nd April, 2019 Intel announced the general availability of Intel Optane DC Persistent Memory. Later after that, IBM introduced Virtual Persistent Memory (vPMEM) in the virtualization platform of IBM Power Systems. So now we have two technology with which we can adopt HANA to enable the use of Persistent Memory.

My Adventures in Machine Learning 2

My project literally starts from scratch. I have some experience in operating SAP BW systems and troubleshooting various performance issues, but that always was human experience applied to a specific technical problem. Now there is an (at least for me) completely new field: Applying Machine Learning to operations. During the last years I read a lot about the AI hype. AI was applied almost exclusively to business cases. This means to me stuff inside the SAP applications or some other business software layers. I haven’t really seen a case for trying to apply AI or Machine Learning below, in the ordinary operations. Sure, there is lots of automation in operations, but hardly anyone that I am aware of talks about AI or ML in operations. This makes it hard to use some best practices which might guide me.

Common Errors and Fix – XSA Web IDE for HANA developments

When I started building objects in Web IDE for HANA on XS Advanced server, there are quite a few number of errors during build or deployment of the objects in HANA. I found answers to those errors in SAP Community forums and that was very helpful. Then I thought of consolidating those common errors and the resolutions at one place in this technical document.

Cross-MTA Dependencies. Custom UI5 Library Reference Example.

While there is a lot of good information available on cross-MTA dependancies, I thought it would be useful to create a complete working example for loading a custom UI5 library cross-MTA.

To demonstrate the cross-MTA capability I will create two MTA’s containing UI5 applications

SAP Hana 2.0 Revision Upgrade

Introduction

One of the key responsibility of SAP administrator is to maintain HANA database. Hana database maintenance means variety of administration tasks like performance monitoring, enforcing security standards, patching & upgrade of database etc. In this blog I will talk about HANA revision upgrade from version 2.00.040.00 to 2.00.043.00

HANA 2.0 Running inside Docker

Intro

When I was searching for any SAP HANA 2.0 inside container, the only thing I was able to find was about SAP HANA Express edition, how to pull images from docker hub with express SAP HANA inside. Nothing about how to create your own image… So here is my try :).

Good Things Come Together: DBeaver, SAP HANA Spatial & Beer

German areas with high Biergarten density? Spoiler: The result won’t surprise…

SAP HANA Spatial offers in-database capabilities for handling and processing geospatial data. Furthermore, by leveraging the SAP HANA embedded machine learning capabilities developers are equipped with the ability to infuse spatial analytical models into their applications without the explicit need to actually visualize the geo-referenced input data.

SAP Secure Network Communication (SNC) Encryption configuration from SAP Portal to ABAP systems and SAP Gui to ABAP systems

Background

As per the client request to encrypt the SAP Portal traffic to SAP ABAP systems and SAPGUI encryption to ABAP systems as part of their Infosec policy. Encryption is implemented using the  SAP Secure Network Communication (SNC). This document explains about step by step configuration of SNC Encryption on the existing SAP Gui to ABAP systems and SAP Portal Traffic to ABAP systems. SNC can be implemented in HANA On premise and Hana Cloud Landscapes as well.

Non Equi join in SAP HANA 2.0 Web IDE

Purpose:

Purpose of this blog is to demonstrate the use of “Non Equi join” in SAP HANA Modelling. SAP HANA 1.0 modelling does not support the Non Equi join between two data set, however in hana 2.0 SAP Web IDE modelling new feature added to support Non Equi join.

Sum of Multiple Rows based on a condition (validation) without using LOOP in SAP HANA

REQUIREMENT

This blog post is regarding the validation of “Production Ratio” in Supply Chain Management for the monthly bucket in SAP HANA.

For the calculation of “Production Ratio” you can go through my previous Blog.

Minus set operation in SAP HANA 2.0 Web IDE

Purpose:

Purpose of this blog is to demonstrate the use of “Minus” set operator in SAP HANA Modelling.

SAP HANA 1.0 modelling does not directly support the Minus operation between two data set, however in hana 2.0 SAP Web IDE modelling new feature added to support Minus operation between two data set.

Duplicating ASE Table Placement and Permission in HANA

I am comfortable with ASE. For HANA it’s a little different right now, so coming up to speed in HANA often means that I am comparing what I know in ASE with what I don’t know in HANA. Take table placement and permission for example. Here is what I have discovered so far, and it can get complicated very quickly.

HANA – Linux staging

A lot of customers asking for the optimal operation strategy regarding Linux/HANA and how it will change their current operational processes. So, we talk about lifecycle management – patching of the different components of a system.

Looking forward for the next available value in a table without using LEAD or LAG function or LOOPING in SAP HANA

REQUIREMENT

This blog is regarding the calculation of “Production Ratio” in Supply Chain Management for the monthly bucket in SAP HANA.

The client wanted to see, Production Ratio of a year for each month for a particular Product, Location and Product Version combination. In my case Production Ration was calculated as (Quantity / Total Quantity * 100) for each month. The catch is when there is no value for Quantity and Totaly Quantity in a month, then we have to look forward to the upcoming months for values.

SUSE – Let’s migrate “saptune” to version 2

In May, 2019 SUSE made an announcement on new saptune version, which looked promising as they eliminated the hard-coding of parameters and instead, they have listed in a configuration file. Also more SAP Notes will be included in saptune which results in less headache during system configuration. I got excited to use this new version of saptune but it was not generally available until July, 2019.
