Megarac SP Gui / IPMI

In meinem NAS nutze ich seit vielen Jahren als Motherboard ein ASRock C2550D4I mit einer recht stromsparsamen on-Board CPU und einer BMC/IPMI Schnittstelle, welche Fernwartung über einen separaten LAN Port möglich macht.

BMC = Baseboard Management Controllers
IPMI = Intelligence Platform Management Interface

Bei einem BMC Update hat sich leider die WebGui verabschiedet und ich musste mir die Sache auf der Konsole anschauen. Dafür habe ich IPMITOOL installiert und verwendet. Dabei stellte sich heraus, dass lediglich die Netzwerkeinstellungen verloren gegangen sind.

Hier einige hilfreiche Befehle im Umgang mit dem IPMITOOL, welche mir geholfen haben. Über diesen Weg lässt sich ebenfalls das Passwort des Admin Users zurücksetzen.

[HR] Abrechnungsergebnisse lesen

Reports:

RPCLSTRD – Anzeige des Clusters RD (Abrechnungsergebnisse Deutschland), Tcode: PC_PAYRESULT
H99_DISPLAY_PAYRESULT – Anzeigen von Abrechnungsergebnissen

Abrechnungsergebnistabelle:

Eine sehr schöne Übersicht über die Tabellen: https://l3consulting.de/die-tabellen-im-abrechnungscluster-des-sap-hcm-verstehen/
Die Tabelle RT enthält die Ergebnislohnarten der ausgewählten Abrechnungsperiode. (RT_ = komprimierte Darstellung)

Funktionsbausteine:

HR_GET_PAYROLL_RESULTS – Lesen von Abrechnungsergebnissen für Monats- und Jahresreports
PYXX_READ_PAYROLL_RESULT – Generischer Import von Abrechnungsergebnissen
HRCM_PAYROLL_RESULTS_GET – Abrechnungsdaten einer Person ermitteln

Hinweise zu Bausteinen: https://blog.hr-manager.de/2011/09/abap-abrechnungsergebnisse-lesen-per.html

Logische Datenbank:

Eine weitere Möglichkeit ist die Nutzung der logischen Datenbank PNP. Die Verwendung logischer Datenbanken ist jedoch obsolet und sollten daher nicht mehr verwendet werden.

[SAP] Install SAP Gui for Java 7.50 on Linux Mint 20

Download

First have a look at the Requirements and FAQ.
Find the download link to the SAP Support Portal here. You will need a valid S-User and download permissions.

If you are not able to download the installer in the Support Portal, there is a little workaround. Both, the installer for SAP Gui for Windows and SAP Gui for Java are also delivered with the AS ABAP 752 SP04, developer edition:

“The actual download (in the form of several .rar files), along with more information is available from the SAP Community Trials and Downloads page. Search for “7.52 SP04″ for convenience.”

You will have to download all 11 .rar files (about 14,6GB). When unziping, you’ll find a folder called client (about 1,2GB) containing both installers.

Installation

Since SAP Gui 7.50 Rev 5, Oracles JDKs is not necessary to run SAP Gui for Java, instead you are able to use OpenJDK. Read more about it here. And since version 7.50 Rev 8 the installer includes SapMachine and OpenJFX. Read more about it here. In this case, you don’t even have to install OpenJKD and OpenJFX by yourself and don’t have specify the module path, because it comes containerized within the SAP Gui.
So better first check the version of your downloaded gui. I’ve got SAP Gui 750 rev 5 within the AS ABAP 752 SP04. So let’s install openJDK & openJFX.

sudo apt-get install openjdk-11-jre openjfx
java --version

Finally lets install the SAP Gui:

cd JavaGUI/
java -jar PlatinGUI750_5-80002496.JAR install

The important step during the installation of SAP Gui for Java Rev 5 is to define the option for the module path. The module path hast to point to the OpenJFX lib-path:

/usr/share/openjfx/lib

Now you should be able to run the SAP Gui on Linux Mint 20

Eclipse ADT

When using Eclipse with ADT in combination with SAP Gui for Java and receiving the following error:

"The system reqirements are not met.Could not find: javafx.propertiesin: /usr/lib/jvm/java-11-openjdk-amd64/libYour Java Virtual Machine seems not to support JavaFX, required to run the SAPGUI for Java 7.50 rev 5.Please make sure you provide a valid path to the Java FX modules during guiinstallation."

You also have to add the OpenJFX path to the eclipse.ini file. Read more about it here.

--module-path=/usr/share/openjfx/lib
--add-modules=ALL-MODULE-PATH

[Software] Save battery power on laptops

With TLP I was able to extend the battery life of my ThinkPad E595 significantly.

“TLP is a feature-rich command line utility for Linux, saving laptop battery power without the need to delve deeper into technical details.”
https://linrunner.de/tlp/

If you prefer tools with UI, check TLPUI: https://github.com/d4nj1/TLPUI
There is also a repository for it:

sudo add-apt-repository ppa:linuxuprising/apps
sudo apt update
sudo apt install tlpui

When using a ThinkPad, there are specific kernel modules that can be installed.
https://linrunner.de/tlp/installation/ubuntu.html#thinkpads-only

Check with tlp-stat -b

Install with:

sudo apt install acpi-call-dkms tp-smapi-dkms

Another tool to monitor your power usage is PowerTOP:

“PowerTOP is a Linux tool to diagnose issues with power consumption and power management.”

[Proxmox] Installing Cockpit with ZFS Manager extension

The Cockpit ZFS Manager requires Cockpit version 201 or above. In the Debian Buster repository there’s only cockpit version 188, so you have to use the buster backports repository, which contains cockpit version 223.

# install cockpit
echo "deb http://deb.debian.org/debian buster-backports main" > /etc/apt/sources.list.d/buster-backport.list
apt update
apt-get -t buster-backports install cockpit
# add ZFS manager
git clone https://github.com/optimans/cockpit-zfs-manager.git
cp -r cockpit-zfs-manager/zfs /usr/share/cockpit
# start cockpit
systemctl start cockpit.service
systemctl enable cockpit.service
systemctl status cockpit.service

Now browse to https://ip-address-of-machine:9090 and login.
