  • Linux on POWER

    Linux on POWER

    http://ibmsystemsmag.com/CMSTemplates/IBMSystemsMag/Print.aspx?... close window Print May 2016 | by Jaqui Lynch IBM is serious about Linux on POWER. Linux now runs on every POWER8 server, with specialized offerings for Linux. These include the new LC (Linux only, PowerKVM only) servers, the L model (Linux only) servers, Linux IFLs, EasyScale for MSP offerings, and SAP Hana on POWER. Additionally, significant work has been done to encourage ISVs to increase their offerings on Linux on POWER, resulting in a flourishing ecosystem that wasn’t available on POWER five years ago. Power systems are designed for big data and optimized for performance and scalability. They provide great I/O and memory bandwidth with significant reliability and other availability features not available anywhere else except the mainframe. With full support for various levels of RHEL (Redhat Enterprise Linux), SLES (SuSE Linux Enterprise Server) and Ubuntu, it’s a great time to consider migrating to Linux on Power. Here are some decisions to make: 1. Do you want to run Linux alongside other workloads like AIX or IBM i 2. Do you want to run a Linux only server 3. Do you want to use and HMC or virtual HMC to control the server (won’t work with PowerKVM) 4. Do you want to use PowerKVM or PowerVM for virtualization 5. Do you have some dark cores and memory that you would like to run Linux on at a reduced rate 6. Do you have x86 workload running on Linux that you would like to migrate 7. Do you want to reduce costs for IBM software (PVU based licensing) Reducing costs Software can be expensive, especially middleware.

    1. D-Bus a D-Bus FAQ Szerint D-Bus Egy Interprocessz-Kommunikációs Protokoll, És Annak Referenciamegvalósítása

    Az Udev / D-Bus rendszer - a modern asztali Linuxok alapja A D-Bus rendszer minden modern Linux disztribúcióban jelen van, sőt mára már a Linux, és más UNIX jellegű, sőt nem UNIX rendszerek (különösen a desktopon futó változatok) egyik legalapvetőbb technológiája, és az ismerete a rendszergazdák számára lehetővé tesz néhány rendkívül hasznos trükköt, az alkalmazásfejlesztőknek pedig egyszerűen KÖTELEZŐ ismerniük. Miért ilyen fontos a D-Bus? Mit csinál? D-Bus alapú technológiát teszik lehetővé többek között azt, hogy közönséges felhasználóként a kedvenc asztali környezetünkbe bejelentkezve olyan feladatokat hajtsunk végre, amiket a kernel csak a root felasználónak engedne meg. Felmountolunk egy USB meghajtót? NetworkManagerrel konfiguráljuk a WiFi-t, a 3G internetet vagy bármilyen más hálózati csatolót, és kapcsolódunk egy hálózathoz? Figyelmeztetést kapunk a rendszertől, hogy új szoftverfrissítések érkeztek, majd telepítjük ezeket? Hibernáljuk, felfüggesztjük a gépet? A legtöbb esetben ma már D-Bus alapú technológiát használunk ilyen esetben. A D-Bus lehetővé teszi, hogy egymástól függetlenül, jellemzően más UID alatt indított szoftverösszetevők szabványos és biztonságos módon igénybe vegyék egymás szolgáltatásait. Ha valaha lesz a Linuxhoz professzionális desktop tűzfal vagy vírusirtó megoldás, a dolgok jelenlegi állasa szerint annak is D- Bus technológiát kell használnia. A D-Bus technológia legfontosabb ihletője a KDE DCOP rendszere volt, és mára a D-Bus leváltotta a DCOP-ot, csakúgy, mint a Gnome Bonobo technológiáját. 1. D-Bus A D-Bus FAQ szerint D-Bus egy interprocessz-kommunikációs protokoll, és annak referenciamegvalósítása. Ezen referenciamegvalósítás egyik összetevője, a libdbus könyvtár a D- Bus szabványnak megfelelő kommunikáció megvalósítását segíti. Egy másik összetevő, a dbus- daemon a D-Bus üzenetek routolásáért, szórásáért felelős.

Am Anfang war der Quellcode Entstehungsgeschichte und Werdegang von Linux Entwicklung und Diversifizierung der Distributionen Der Wert von Linux oder: „Wat nix kost, dat is och nix.“ Andreas Klein ORR 2016 1 Am Anfang war der Quellcode (70er) ● 1969, Ken Thompson u. Dennis Ritchie erstellen die erste Version von Unix in Assembler. ● Von 1969-1971 entwickeln sie gemeinsam die Programmiersprache B. ● Ab 1971 erweiterte in erster Linie Dennis Ritchie B, um weitere Elemente und nannte sie Anfangs NB (new B). ● 1973 waren die Erweiterungen soweit gediehen, das er die stark verbesserte Sprache C nannte (Brian W. Kernighan hat ebenfalls maßgeblich dazu beigetragen). //Unix=25 PCs ● Bis 1974 war das gesamte Betriebssystem UNIX vollständig in C implementiert und wurde mit einem C-Compiler kostenfrei an verschiedene Universitäten verteilt. ● 1978 wurden bereits über 600 Computer mit dem UNIX-Betriebssystemen betrieben. ● Das aufblühende Zeitalter der Computerisierung der 70er Jahre war geprägt vom regen und freien Austausch von Programmen und dessen zugrunde liegenden Ideen. Sinnvoller Weise tauschte man diese als Quellcode untereinander aus. ● 1979 wurde von AT&T die letzte UNIX-Version 7, mit freiem Quellcode veröffentlicht. Andreas Klein ORR 2016 2 Am Anfang war der Quellcode (80er) ● 1980 – 1983 AT&T sowie zahlreiche andere Unternehmen beginnen mit der Kommerzialisierung von UNIX, durch Koppelung an stark beschränkenden Lizenzen und Geheimhaltung des zugrunde liegenden Quelltextes. ● Richard Stallman kündigt am 27. September 1983 in den Newsgroups net.unix-wizards und net.usoft das GNU-Projekt an. ● Am 5. Januar 1984 begann Stallman offiziell mit der Arbeit am GNU-Projekt, nachdem er seine Stelle am MIT gekündigt hatte.

Um die einleitende Frage zu beantworten, erkläre ich in diesem Kapitel zuerst einige wichtige Begriffe, die im gesamten Buch immer wieder verwendet werden: Betriebs- system, Unix, Distribution, Kernel etc. Ein knapper Überblick über die Merkmale von Linux und die verfügbaren Programme macht deutlich, wie weit die Anwendungs- möglichkeiten von Linux reichen. Es folgt ein kurzer Ausflug in die Geschichte von Linux: Sie erfahren, wie Linux entstanden ist und auf welchen Komponenten es basiert. Von zentraler Bedeutung ist dabei natürlich die General Public License (kurz GPL), die angibt, unter welchen Bedingungen Linux weitergegeben werden darf. Erst die GPL macht Linux zu einem freien System, wobei »frei« mehr heißt als einfach »kostenlos«. 1.1 Einführung Linux ist ein Unix-ähnliches Betriebssystem. Der wichtigste Unterschied gegenüber historischen Unix-Systemen besteht darin, dass Linux zusammen mit dem vollstän- digen Quellcode frei kopiert werden darf. Ein Betriebssystem ist ein Bündel von Programmen, mit denen die grundlegend- Betriebssystem sten Funktionen eines Rechners realisiert werden: die Schnittstelle zwischen Mensch und Maschine (also konkret: die Verwaltung von Tastatur, Bildschirm etc.) und die Verwaltung der Systemressourcen (CPU-Zeit, Speicher etc.).
