Several years ago, I presented a session on setting up Openshift Container Platform (RHOCP) on z. In new RHOCP releases, you have the option of multi-node or single node virtual machine to do all the work. I'll be reviewing the differences in installation process getting this working.
An introductory class that covers some of the key reasons for virtualization technology, its fundamental concepts, and how z/VM fits into the 'big picture'; later relating these fundamental virtualization concepts to how they are actually implemented within z/VM itself.
The XEDIT editor is a sophisticated editor with a large subcommand set. It can be quite easy to use and yet extremely powerful and nearly infinitely tailorable. In this session, the speaker will cover a tiny bit of history, the anatomy of an XEDIT session, how to use the basic edit functions and navigation and even some intermediate topics to show how powerful the XEDIT environment is.
DASD storage on zLinux has seen improvement over the years. HyperPAV, EAV, ESE - these technologies can make life much easier for administering a large number of guests. I will go over the project we undertook to modernize our zLinux disk implementation - from setting up new disks on the DS8K to the IOCDS and user directory changes and finally the steps to migrate zLinux systems to HyperPAV.
This presentation provides a closer look at several upcoming z/VM updates for I/O, including new 1-END HYPERPAV HYPERSWAP enablement, FICON RAS support, SCSI recovery improvements, PCIe device pooling, and more IO-related z/VM upgrades.
You’ve installed the tools—now it’s time to make them deliver value. This “beyond the basics” session focuses on practical configuration and real-world usage of IBM Operations Manager, Tape Manager, and Backup & Restore Manager for z/VM. Learn how to: - Configure console monitoring and establish automated operations schedules with Operations Manager - Provision and manage tape resources to support reliable, scheduled backups with Tape Manager - Integrate these capabilities to implement fully automated backup procedures with Backup & Restore Manager Walk away with a clear, actionable approach to turning installed components into an operational, resilient system.

This session will expose the secrets of z/VM for amazing tricks Linux can do nowhere else. z/VM is the original personal computer and more powerful than any other hypervisor. Linux is the one truly open source Unix-like system and more flexible than all else. Together they serve everyone from hobbyist or student to Fortune 100 enterprise. This session will discuss and demonstrate building from source, shared disk, immutable systems, and extreme customization.
Several new memory management functions are being developed for z/VM. This presentation will cover the following topics: 1. Active Drain 2. Memory Terminology Changes 3. Memory Overcommitment Control 4. Memory Management Infrastructure
z/VM V7.5 has been announced in preview, and while the future isn't here quite yet, changes are coming in the space of security -- not limited to RACF for z/VM, but especially in that space. The goal of this presentation is to start you thinking about what the future may hold for security on your favorite platform, and what you may need to do to prepare.
The CITI LinuxONE team was asked to provide encrypted Mongo database to meet PCI-DSS global requirments. Using zVM and custom built processes we were able to deploy hundreds of LUKS based filesystems
Mainframe operating systems produce A LOT of performance data. It isn't enough to look at screens and reports anymore. Data can be delivered to InfluxDB and Prometheus for use with new visualization tools like Grafana. These tools are becoming more and more important for data display. We will show how these tools can be integrated into your existing performance management landscape. Sending data to Open Telemetry will also be discussed and how it integrates with Prometheus.
You may know GetShopz as a CMS utility that simplifies and secures the transfer of z/VM service from IBM Shopz and IBM ServiceLink to a z/VM system. New in the latest release, GetShopz dramatically speeds up second-level installation and upgrade by accelerating the transfer and decompression of installation media ZIP files. We will step through existing and brand-new workflows to benefit both new and experienced users of GetShopz.
This presentation is a foundational deep dive into the ICIC architecture, exploring how it simplifies IaaS management for IBM z/VM and other hypervisors. Focus will be given to recent release cycles, specifically highlighting the high-impact enhancements introduced in the recent General Availability (GA) V1.2.5. Attendees will learn about improved scalability, security hardening, and revamped user interfaces.
Whether implementing hybrid cloud or supporting server consolidation projects, customers are implementing mission critical applications on Linux on IBM Z and LinuxONE. In this session, the speakers will focus on real customer problems and associated solutions with managing this new infrastructure, including monitoring messages, monitoring spool space, sending alerts, feeding data to analytics platforms, automatically fixing a problem, and backing up and recovering critical data.
The z/VM virtual switch is a powerful option for connecting your virtual machines to an external network. We'll discuss various deployment options, including IEEE VLANs, link aggregation, global VSWITCHes with shared link aggregation port groups, the HiperSocket bridge, and the new support for the Network Express (OSH) adapter. We'll even spend some time talking about how to diagnose problems.
In my experiences with network teams, they seem to not understand how IBM z networking (specifically OSA hardware) works. Their reality of having a single physical wire carrying potentially over 100 IP addresses is beyond their "norm". Meanwhile, many IBM z SysProgs do not have mucn experience with TCP/IP (or VTAM, for that matter), which can impede working with the network team to solve connectivity issues. This presentation is a high-level review of TCP/IP v4 addressing and routing, along with common IBM z debugging tools that can be used to provide the networking team with connectivity data. The concepts and tools are common across all IBM Z operating systems, but I will touch on the implementation differences between z/VM, z/OS, VSEn and common Linux implementations.
Over the past couple of years I have worked on providing CMS with a SSH Server capability. I now have a working PoC that enables a full interactive SSH session or a 'one-shot' command mechanism. In addition, I have worked on providing CMS with a Python implementation (3.10+) which necessitated porting OpenSSL (1.1.1k and 3.6.0) in order to use pip3 to install packages from external repositories. Having Python means web-based tools are available including GUIs that enable tooling and applications to be built and run on CMS. Python is able to deal with files encoded in EBCDIC (IBM-1047) and ASCII (ISO8859-1) as I've developed an ASCII layer to multiple OpenExtension APIs. I am also working on a port of Perl 5.42.2 (the OpenSSL test suite uses Perl to automate its tests). This is in its early stages but I hope to have something to share during this session.
