Linux – Memory Management insights

Nowadays the Linux memory management of a SAP system (application server) or SAP HANA system getting more important since the clear roadmap of SAP (Linux as only OS for HANA) is showing that the amount of Linux installations is rising steeply.

One of the worst things which could happen to such a system in context of performance is swapping or paging. But is swapping and paging the same?

HANA – Savepoint details

There are a lot of sources where you can find some rudimentary information about how a HANA savepoint is working or which event is triggering one. But not really how the different phases are working or which dependencies are there and how you can determine the thread details. In context of a customer issue I have done some researching and reengineering.

Load flat file decimal values to ADSO (SAP BI) and access in SAP HANA Cal view ( eclipse/H Studio)

We had a requirement to load GAS emission data into SAP BI, as the business does a lot of manual calculations in excel, to get the emission factor which is dependent on multiple values. They first need to sum up the values, do a standard deviations, SQRT of some NO2, Co2, IC4 values, divide it by some factor etc., which is a heavy excel based lookups and calcuations.

Flowgraphs in XSA (express edition H2SPS04)

Recently I was looking into flowgraphs in HANA 2 XSA SPS04. Since I have background in XS, HANA Modeling, and SAP BODS, I thought this may be an easy exercise to achieve.

Before getting into the solution, let’s see what is a flowgraph? A flow graph is the diagram representation of some logic executed with 0 or more filters (input params) in order to get some output.

Using SAP HANA as a service (HaaS) with Esri ArcGIS Enterprise 10.7.1 and Pro 2.4

This means ArcGIS Enterprise can use SAP HANA Service as the underlying database to support ArcGIS’s System of Record, System of Insight and System of Engagement.  HaaS is the first-ever database as a service that is fully supported by Esri ArcGIS technology.

Basically, the SAP Cloud Platform, SAP HANA service gives you cloud instances of SAP HANA on-demand, that are managed by SAP.  It’s great if you want to stand up HANA quickly and only want to pay for what you use.

HANA Studio – Convenient code snippet storage

This is a quick blog post to show a nifty place to store code snippets in HANA Studio. I’m thinking of snippets that you execute often and lose somewhere in your HANA Studio tabs, the ones where you haven’t been super diligent about saving as sql files. (Confession time, this is me, I have useful code snippets stored in lots of random places that seemed like a good place at the time.)

Note: I know HANA Studio is “dead” with HANA 2.0, however many people are still using it and are still using HANA XS Classic, so perhaps this tip will help someone have a nicer experience in the client tool.

SAP HANA Hardware and Cloud Measurement Tools (HCMT) – Replacement of HWCCT Tool

Recently before installing SAP HANA on certified server, I thought of running SAP HANA Hardware Configuration Check Tool on the provisioned server. The latest available HWCCT version in service marketplace is 244 and I have used the same to perform the check.

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

NOTE: I have also used version 242 and the details provided below are encountered in both the version. 

First error you will encounter on running hwcct command for version 242 and 244 will be –

./hwcct: error while loading shared libraries: cannot open shared object file: No such file or directory

I was able to get this file from the existing HANA database and copied this file to the lib directory of hardwareConfigurationTool folder

NOTE: This file is only available in HANA 2.0 SPS 04. You won’t be able to find this file in lower HANA database version. 

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

After that, above error got resolved. But now during landscape evaluation I encountered below error –

There is no SAP Note which addresses above issue. At first I thought there might be some additional pre-requisites as I’m using recently certified SUSE version (SLES 15 SP 1) but I could not find any. I raised message to SAP and found that – Its a programming error which is reported since HWCCT 242 and 244 version.

Also SAP HANA Hardware Configuration Check Tool (HWCCT) has been end of life-cycle (EOL) on Aug 1st, 2019. So now no further releases or patches will be provided to accommodate its fix. (As per SAP)

What’s NEXT?

A new SAP HANA hardware and cloud measurement tools (HCMT) is or will be introduced as a replacement of HWCCT. I could not find any official announcement of this tool but as per SAP, HCMT will be an official tool to check server before deploying HANA system in future.

HCMT is available for download in Service Market Place, so thought of giving it a try. Below is the official SAP Note for this tool –

2493172 – SAP HANA Hardware and Cloud Measurement Tools

Download the pdf attached in above SAP Note as it gives details on the usage of HCMT tool.

HCMT Overview

The SAP HANA hardware and cloud measurement tool (HCMT) allows customers and partners to collect information on the infrastructure intended for SAP HANA deployment. The tool measures whether the planned hardware or cloud system complies with the requirements defined by SAP.

Furthermore, it gauges whether the system planned for SAP HANA deployment can achieve satisfactory base performance by meeting the minimum requirements defined as well as satisfactory overall performance given the intended SAP HANA usage.

The measurement results are saved into a single file, which can be uploaded to the SAP HANA hardware and cloud measurement analysis for further analysis and reporting.

NOTE: SAP HANA hardware and cloud measurement tools are based on the requirements of SAP HANA Platform 2.0 or newer. For older SAP HANA versions, refer to the SAP HANA Hardware Configuration Check Tool


You can download the tool from the SAP Support Portal at –> SUPPORT PACKAGES & PATCHES –> Search for: “hana optim”

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

Unlike HWCCT, which is ready to use just by extracting SAR file. Here, with HCMT we need to install the tool on the server.

First extract the tool using SAPCAR

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

It will have setup folder, navigate into the folder and install the tool using hcmtsetup command

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

After setup, the following folder structure is available:

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

The SAP HANA hardware and cloud measurement tool performs a series of automated tests, for example network tests, file system consistency tests, system management BIOS tests, and CPU benchmark tests.

The duration and repeat rate of the tests depends on the type of execution plan that you intend to run.

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

The following execution plans are available:

executionplan.json – Default execution plan that helps you to check if the KPIs for SAP HANA certification are met.

full_executionplan.json – Performs the same tests as the default execution plan, but has a higher test repeat rate and thus a longer test duration. This test is used for SAP HANA certification.

So for people who wants to validate HANA server before installing should use executionplan.json plan to test their HANA servers

NOTE: I have executed this tool for Scale-up System 


◉ You have installed the latest version of the SAP HANA hardware and cloud measurement tool on the system.

◉ You have at least 20 GB of free storage space in the location where SAP HANA data can be placed during the test.

◉ When using nonvolatile memory, mounts for all hosts or an alias of the same name must be available.

◉ Port 50001 must be open for communication.

NOTE: This tool will run for a while, so make sure you run this tool in one of your jump server.

# ./hcmt -v -p <path>/setup/config/executionplan.json

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

Once the execution is completed it will create a file named hcmtresult-<dateandtime>.zip inside the same folder. Transfer that zip file into you desktop

We need to upload the measurement results file and analyze the results to see whether the systems meet the configuration and performance requirements.

Analyzing the Measurement Results

SAP HANA hardware and cloud measurement analysis provides a graphical and textual representation of your measurement results. It allows you to see which parts of your system are doing well and which parts may need some changes or improvements to achieve the required performance.

You can read the pdf attached to SAP Note 2493172 on how to analyze the result..

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam


1. Nice centralized repository for all of our HANA Server checks
2. Graphical insight but tedious to interpret result.


1. Difficult to read or get insight from the uploaded measurement as the result is not provided in the form of dashboard which can be drilled down to get more insight (like S/4HANA Readiness Check)

2. Currently there is no option to share the result to other S-User

3. I would rather prefer a quick summary in one file like below from HWCCT tool over individual selection

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

SAP HANA Study Materials, SAP HANA Tutorial and Material, SAP HANA Learning, SAP HANA Guides, SAP HANA Online Exam

But as SAP suggested that this tool is still in development. So probably we can expect to get more holistic insight from this tool in future.

What’s different in SAP Sales and Distribution (SD) in S/4 HANA

If your knowledge of SAP’s S/4 HANA only came from attending Sapphire, or reading the company’s marketing materials you might think that it was old news. After all, the product launched four years ago and has been pitched so hard since that surely by now every SAP customer must have not only drunk the Kool-Aid dry but also signed up and finished implementing it. But outside of the Orlando conference center spin zone, businesses need more than trade show hype to jump at the latest bright and shiny object. Business cases must be made, budgets approved, and projects scheduled, all of which take time. Lot’s of time.

S/4 HANA CDS View Search and related Fields Information

We used to spend lot of time in identifying the SAP delivered CDS view(s) or Existing CDS View(s) in the system before starting the development which is very important so that we don’t create duplicate objects and also we can utilize SAP delivered objects. Personally I felt the process was really painful and time taking.

As a Coding Savvy I could able to identify the tables which has all the Meta data information about the CDS view(s). So I had created a table function in S/4 HANA system which makes CDS search is easy. I am hoping that developers could able to leverage this code so that they could save lot of investigation time.

SAP HANA Data Strategy


As database and business analytics professionals we have always struggled with implementing the business’s conceptual data model and analytics strategy given the limitations of traditional database technologies. We understand the data and the many attributes that allow us to view the data from many angles, but the traditional database technologies did not allow us to create very wide tables and limited the number of ways we could access the data. These limitations then drove the models to have multiple copies of data summarized for specific use cases. All of these traditional database limitations lead us to create very complex models for solving quite straight forward problems. The complexity of the data models then created limited flexibility and tremendous latency.

Improvements of BW/4HANA Analytical Engine in Q1 2019 with BW/4HANA 2.0

Let us have a glimpse on each of the topics in detail.

Conditions evaluated in SAP HANA

With BW/4HANA 2.0 also the execution of queries with conditions can be pushed down to HANA. For this we introduced a new value 9 for query property ‘Operations in BWA/HANA’ (with technical widely known name TREXOPS). Setting TREXOPS to this value, the OLAP engine tries to push down the calculation of the query containing conditions to HANA.

Improvements of BW/4HANA Analytical Engine in Q3 2019 with NW BW SP16 or Q1 2020 with BW/4HANA 2.0 SP4

We are now with BW/4HANA 2.0 SP 4 and NW BW SP16 shipping those new features. The main driver for those innovations is the SAP Analytics Cloud integration. But a lot of features can also be used in SAP Analysis for Office or the BW/4HANA query preview.

HANA startup tuning – part 2

Starting with HANA 2.0 SPS4 there is a new option called fast restart. This option allows the DB to keep the column store (main area of CS) in memory during a restart of the HDB. So there is a difference to pmem. Persistent memory keeps the data also after an OS restart or power outage. This means that the fast restart option is a bridge technology which can be used independant from CPU and memory type. There are no additional costs to use it. This means also that there is no reason not to use it.

HANA startup tuning – part 1

One of the biggest challenges with SAP HANA databases are the duration of the startups. Here we have to separate the available time and the reload time.

In my career as consultant I’ve seen a lot of HANA databases with pretty long startup times with more than 1 hour. This is also the reason why SAP introduced the fast restart option with SPS4. But which possibilities are there to speed up which phase with which release? Because a lot of DBs are still not on SPS4 and can not profit from new features. How you can identify the bottleneck?

How to send data from Apache NIFI to HANA

NIFI is a great apache web based tool, for routing and transformation of data. Kind of an ETL tool. In my scenario, I am trying to fetch tweets from the Tweeter API, and after that, I wanted to save them to hadoop, but also, filter them and save them to HANA for doing Sentiment Analysis

My first idea was to save them to hadoop, and then fetch them to HANA, but after discovering NIFI, it was obvious that the best solution was to fetch the tweet, then format the json file, and then insert it on HANA.

When to use Execute in SQL Engine for Calculation Views

This posting will give an overview of the implications of the setting “Execute in SQL Engine”. This setting is available for Calculation Views to overrule the default execution behavior.


When Calculation Views are included in queries the query is first optimized in a special engine called “Calculation Engine”. This has a drawback when the query is included in a larger SQL query because in this case two different optimization processes are involved: One for the SQL query part and a separate one for the Calculation View part. This can lead to inefficiencies between the different optimization processes.

Expect Better from your Data Warehouse

As a young man growing up, my teachers, coaches, or other adults would not hesitate to use words like “You can do better”, “I expect more”, and even “Just do your best”. I (like most kids) often fell short of expectations. Each spoken time, these phrases would create an opportunity for me to evaluate how I fell short and how I must change to be successful in the future.

SAP Cloud Platform Extension Factory – Connecting to SAP Commerce Cloud

One of the key components of the SAP Cloud Platform Extension Factory Kyma runtime is the Application Connector.  The Application Connector provides a mechanism to simplify the connection between external systems and Kyma in a secure manner.  Once the initial connection has been established, the registration of the external Events and APIs of the external system takes place. The Events and APIs are then available within the Kyma Service Catalog.  The events can be consumed asynchronously with services and lambdas (serverless functions) deployed within Kyma.  Additionally, the Application Connector provides monitoring and tracing capabilities to facilitate operational aspects.

SAP HANA XSA Email Example

For a few of the items he wanted, like bg-deploy, I was able to point to existing content that hopefully will help. But for some of the items there certainly were lacking examples.  One of them he mentioned was Email from XSA (pure node and xsjs).

This is a particular example or exercise that is often requested but I’m personally reluctant to do. It gets complicated fast because of the dependency upon an external SMTP server and the individual setup and authentication steps needed for the various different providers.

HOW-TO: Activate Master Data Hierarchies for SAP Analytics Cloud (SAC)


SAP Analytics Cloud enables to create dynamic visual stories based on key business areas with trusted data that is managed by IT.

There are many introductions and learning materials for creating powerful reports and dashboards for SAC. All the information shows how to visually deal with data derived from various sources. Since the BW live connection via BW queries does not have all the required features yet, we are using live connection via External SAP HANA Views. The External SAP HANA views are query-based. This is the only way it does work with the master data hierarchies right now.

SAP HANA XSA Controller API Interaction

Since the introduction of SAP HANA extended application services, advanced model (XSA), SAP has supported many new approaches to accessing the platform APIs.  XSA is based upon Cloud Foundry which provides its core functionality via a command line client and a REST enabled web API.  XSA has this same functionality, but most of the focus on platform admin and interaction tends to focus on the CLI interface or the browser-based administrative UI which SAP deliveries. However behind that web UI are essentially calls to the controller APIs. These same APIs can be called from and used in your own applications.  In this blog I’d like to share some experiences trying to use these APIs.  There are some common challenges anyone using them will face and perhaps this blog can be helpful in that regard.

Just another dummy data generator for SAP HANA

The most of the times we don’t have enough data, or even any access to customer real data, so we have to generate some rows. In order to do that, i just wrote a python script to generate dummy data and I want to share it with you.

In very simple terms, this python script works generating rows for a given HANA table; it takes table metadata for columns definitions (taking account data types, length, etc), and then it generates a random value according to column specification. I’m using Python and SAP Python HDBI client for SAP HANA, and I think it would work with PyHDB Python library as well.

SAP HANA Development from Alternative IDEs

In this blog I’d like to revisit the topic of using alternative IDEs but this time also look at how to connect to and use a HANA DB. I think we’ve perhaps created the incorrect impression that only way to perform modern development with HANA (HDI in particular) is to use XSA/Cloud Foundry and the SAP Web IDE. While there is a strong focus on making development easy in the SAP Web IDE and deploying to XSA/CF; that certainly isn’t the only way to develop on HANA.  So in this blog I’ll also dive deep into the topic of using the SAP Cloud Platform based HANA As A Service from outside the Cloud Platform tooling.

Machine Learning with SAP HANA & R – Evaluate the Business Value

In this blog, I will show how to evaluate the business value from a machine learning model built in SAP HANA using R.

Combining SAP HANA & R allows the data scientist or advanced business analyst to leverage the power of SAP HANA and at the same time get the vast functionality from the use of R Packages. The main benefit with an approach of using SAP HANA in combination with R is that it allows you to utilize the power of SAP HANA both in terms of scalability and performance through R scripting. In a nutshell, there is no movement of training data from SAP HANA to the R server/client and the training of machine learning models is performed exactly the same place as where the data resides. In short: algorithms and data are on the same in-memory SAP HANA server.

Capture Change Data with the SDI Flowgraph Table Comparison

When batch-loading data from a source system into your Data Mart or Data Warehouse, you usually look for ways to reduce the to-be extracted data set to minimize extraction time and resource consumption. Ideally, there is a way to only extract changed records, for example, using a change date column. However, this does not always fly. For example, change date columns are not always reliable or deletions are not always tracked in the source table. An alternative would be to switch from batch to log or trigger replication on the source, but you don’t always have this luxury. So, now you have to load the entire source data set, but still you want to identify the change data, to only process delta’s in downstream data flows. How can you identify such change data using batch loading?

How to Connect SAP HANA with GeoServer

Meanwhile SAP HANA and its spatial features can be used with a lot of third party GIS (Geographical Information Systems) tools. One crucial question is on how to connect SAP HANA with these tools. This might be quite different from tool to tool and sometimes also be kind of hidden information, especially when the possibility and support for a certain tool is new and recent. In this blog I go into the details how to connect SAP HANA with GeoServer.
