OMEGAMON Configuration Manager – ein Erfahrungsbericht Vor ca. 10 Jahren wurde PARMGEN als neue, effizientere Methode die OMEGAMON Monitoring-Produkte zu konfigurieren, vorgestellt. Dadurch abgelöst wurde ICAT, das IBM Configuration Assistance Tool, das vorher im Einsatz war und wegen der großen Anzahl Jobs die für die Konfiguration notwendig waren kritisiert wurde. ICAT und PARMGEN unterschieden sich radikal im Aufbau und Workflow und der Umstieg fiel nicht immer leicht, deshalb wurden von IBM lange Zeit beide Tools unterstützt. Seit gut 5 Jahren ist ICAT aber jetzt Geschichte und es wurde nur mehr PARMGEN als alleiniges Tool für die Konfiguration ...
Z technical sales の加山です。 不定期になりますが、COBOL や PL/I の Hint&Tips をご紹介していこうと思っています。 よろしくお願いいたします。 IBM Z の新しいモデルがリリースされると、新しい機械命令が使用できるようになりますが、IBM から提供されている COBOL や PL/I のコンパイラーも新しいリリースと同時にこの新しい機械命令を使えるように改善されていることをご存知でしょうか。 ARCH というコンパイラー・オプションの値によって、ご使用のマシンモデルに最適化されたコンパイルをすることができます。 IBM Z のモデルによって提供されるようになった機能を示します。 英語だらけでピンとこないかもしれませんが、ざっくりと申し上げると演算処理の効率向上があげられます。 特に、桁数の大きい数値や複雑な演算の効率向上に大きな効果を発揮します。 新しいコンパイラーの効果を得るには再コンパイルが必要になりますが、IBM Zにも DevOps を強力に支援する製品群が揃っていますので、効率的に移行を進める検討をご一緒させてください。 参考.Enterprise COBOL 製品情報(2021/8時点) 参考.Enterprise PL/I 製品情報(2021/8時点) 以上
IBM Enterprise COBOL for z/OS 6.1, released in 2016, reaches end of service Sep 30, 2022 . The replacement product is IBM Enterprise COBOL for z/OS 6.3. Updating from COBOL 6.1 to later versions of Enterprise COBOL is very straight-forward compared to the migration from COBOL 4 or earlier to COBOL 5 or later. Simply install the latest compiler and recompile with the same compiler options used in 6.1. The compiler will automatically update any options that have been renamed and tell you in the listing if any replacements were made. The underlying compiler infrastructure remains the same between 6.1 and 6.3, so this update will be trivial. If you ...

With the GA of Red Hat OpenShift Container Platform 4.8 the following additional functions are supported on IBM Z and LinuxONE. What is New for Z on 4.8: Three-node cluster Allows to setup a cluster with only three nodes. The nodes are control nodes that contain the compute pods and therefore combine both types of nodes. To accommodate the additional load of the pods, which run on compute nodes in a 5+ node scenario, the memory footprint of the control plane nodes is increased to 21 GB each as well as using 6vCPUs. This results in the same overall memory footprint as a five-node cluster. We successfully tested to setup a Three-node Cluster ...

A rich IaaS platform - and an infrastructure for Red Hat OpenShift on IBM Z The traditional layer classification of cloud services is into Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS), and Software-as-a-Service (SaaS). And while there are many more variants proposed today, this still provides a useful way of looking at cloud architecture, with each layer providing its own value as well as services that are used by the layer above. IBM Cloud Infrastructure Center provides the IaaS on IBM Z and LinuxONE, as well as providing the infrastructure platform for Red Hat OpenShift which provides the PaaS. And with the new version 1.1.4 now announced ...

What a shock to be named a “Lifetime IBM Champion”! It’s such a privilege to be an IBM Champion and have the opportunity to communicate and collaborate with the 700+ global rockstars of IBM technology who also bear the title. Now being named a Lifetime IBM Champion has taken this to a new level. Since rely, thank you IBM for this singular honor! I’ve been asked by IBM to write about my advocacy journey. While the tale may only be useful as a cure for insomnia, here are a few thoughts. I began mainframe life as a COBOL and CICS programmer in 1990 and was recruited by a mainframe training company that was creating an exciting new training ...
The textbook definition of digital inclusion is the ability of all individuals and groups to access information and communication technologies. However, I believe that this definition should extend past the “access” criteria. Digital inclusion also speaks to the digital skills of individuals and the type of internet access they have, as these impact their use of digital media. This means that just having access to a mobile device alone is not sufficient; things such as the type of internet connection and the level of digital skills are important determinants of one's participation in digital media. In countries like South Africa, where I am from, a large percentage ...

The actual name is IBM Wazi Developer for Red Hat CodeReady Workspaces but with so many nouns in a title, the community was relieved when IBM started simply calling it IBM Wazi Developer. As companies have pushed software development into containers, at least for distributed applications, and due to the close relationship between IBM and Red Hat, it was logical and wise that containerization also be applicable for mainframe development. The classic arguments about mainframe developers nearing retirement, new hires and the skills they have, tools they have learned from or use, developers being responsible for not just the front end rather also the mainframe ...
