Zowe Jupyter App: A Big Hit at the Poughkeepsie zModernization Summit Event

By | Blog, Zowe

Guest blog from Daniel Jast – IBM Z Systems Technical Specialist

The Poughkeepsie Client Experience Center recently hosted the annual IBM Z Summit Program Technical training event titled, zModernization Summit Event. At the training event, we provided 20 of the new IBM Technical Sellers in Z with hands on training in some of the “modernizing” applications on Z. These technologies included CICS, DB2, z/OS Connect, z/OSMF Zowe, Spark, ICP, Docker and more. The week let participants take a cobol application running on z/OS, expose the applications services into APIs, and then create a containerized application with those APIs which was then deployed out to the IBM Cloud. The application that was being run was a stock trading application which allowed users to create an investment portfolio, add stocks to the portfolio, and so on. We then let users get a hands-on experience on the Zowe Desktop and CLI, seeing how easy and simple completing complex z/OS tasks can be for new users by utilizing Zowe.

On the Zowe Desktop, we had created an IFrame application that had the Jupyter Notebooks running right on the Zowe Desktop. Jupyter Notebooks are used to exploit Spark to analyze data sources of your choosing. We had the Jupyter Notebooks analyzing Investment portfolio data which the users had created unknowingly as they worked through the technical labs throughout the week of training.

Training participants thoroughly enjoyed the Zowe and Jupyter Notebook piece. After getting previous training on “green screen” interfaces to z/OS, the Zowe Desktop and Zowe CLI were very well received. The audience was majority straight out of college, matching the target audience for the Zowe platform. When participants were asked what their highlights and key takeaways from the week of training were, some mentioned Zowe explicitly:


“Being able to learn more about Zowe and more innovative technologies integrated with Z.”


“Highlight: Zowe presentation!”


“My favorite (presentation) was the Zowe presentation”


“I think I really enjoyed learning about Zowe, and the hands on lab are super helpful in understanding!”


If you are looking to add Jupyter Notebooks to your Zowe Desktop, you can follow the github documentation posted here:

Dalian University of Technology Expects to Deliver New Zowe Tools

Guest blog from Kun LU, Ph.D., Associate Professor, Director of Innovation Practice Center, School of Software Technology – Dalian University of Technology – China

When it comes to the Best DevOps Open Source Project, do you think it has anything to do with the IBM mainframe? Well, it does.  Open Mainframe Project’s Zowe, the first open source project based on z/OS, was named as a one of the finalists for the “Best DevOps Open Source Project” category by  Zowe is an open source software framework that provides solutions that allow development and operations teams to securely, manage, control, script and develop on the Mainframe like any other cloud platform. Leveraging the Zowe framework, we (DLUT) plan to develop and contribute a few tools to Zowe to help developers be more efficient, productive and agile in their daily work on z/OS.

We will work closely with IBM CSL CICS team and expect to deliver the following tools as Zowe plugins for CICS customers, first for the China market, in 3Q/4Q this year.

CICS Statistics Visualizer plugin

In the past, CICS health status check needs to be done manually by CICS experts who have profound CICS skills and experience.  The workflow includes understanding the system design, configuring CICS statistics programs and collecting CICS statistics data from CICS sample region at service peak time by uploading statistics data and analyzing the data, and finally generating reports and diagrams.  With CICS Statistics Visualizer plugin on Zowe Web UI, all the work can be done automatically.  The plugin also supports statistics data comparison of a single region at different time intervals, which can largely simplify the work the customer used to do before to monitor and analyze the system, like CICS health status change after CICS upgrade or configuration change, the trend of system resource utilization over time etc.  Furthermore, key CICS health indicators can also be queried by a simple shell command line through Zowe Command Line Interface (CLI).

CICS Liberty Debugging Assistant plugin

In the past, the customer needs to collect and store a list of debugging information from different storages and locations to troubleshoot a CICS Liberty problem.  This includes CICS Job log from mainframe JES, JVM profile and Liberty configuration files, STDERR/STDOUT/JVMTRACE files and Liberty output files like messages.log, trace.log and ffdc from zFS, MVS system dump accompanying with JAVADUMP, SYSDUMP and CEEDUMP dumps depending on the problem.  In addition, CICS trace level needs to be configured and Interactive Problem Control System (IPCS) must be used to format the unformatted dumps.  With CICS Liberty Debugging Assistant plugin, all the debugging related configuration, debugging information collection and dump formatting can be done conveniently by one-click operation.

CICS Application CI/CD plugin

Nowadays, CI/CD is widely used in software development.  More and more customers have increased demand on the z/OS development CI/CD to modernize the mainframe development, integrate with the distributed platform development, and assist the full stack developer to work with the mainframe services.  Zowe acts a good platform to eliminate the operation gaps to enable the z/OS development CI/CD, which provides some plugins like CICS and DB2 plugins to help simplify the application development.  As Git is widely being used for the distributed development, to centralize the code management, Zowe plugins (or cli) can be built for mainframe DevOps, like:

  • Trigger the build automation and end to end test automation (e.g. online COBOL or batch COBOL)
  • Trigger the env update when there is a CICS or DB2 configuration update
  • Deploy update into the multiple environments

IBM Systems Magazine | Getting to Know the Open-Source Zowe Project

By | News, Zowe

Zowe—the first open-source framework for z/OS—is poised to break new ground for IBM Z clients. Announced on Tuesday, Aug. 14, at SHARE in St. Louis, by executives from IBM, CA Technologies, Rocket Software and the Open Mainframe Project, the open-source project promises to be a game changer.

“Open source redefines industries across the board. We’ve seen it solve problems and lead to innovative solutions. Open source changed the automotive industry and the cloud changed networking, too,” says John Mertic, director of program management for The Linux Foundation and director for the Open Mainframe Project. “We’re excited to see what Zowe and open source will do for the mainframe industry.”

Clabby Analytics | A Different View: The Zowe Initiative and the “Open Mainframe”

By | News, Zowe

At this year’s Open Source Summit IBM, CA Technologies and Rocket Software announced an open-source software framework known as “Zowe” – a framework designed to draw new application development to the z/OS operating environment, as well as making it simpler to integrate modern applications on other platforms (systems, servers, mobile devices, etc.) with mainframe servers. We at Clabby Analytics, however, see this move as a heck of a lot more than application development and integration – we consider it a major step forward in opening up the mainframe and making it a transparent member of any enterprise hybrid cloud environment.

Heise Developer | Zowe project gives the mainframe a GUI

By | News, Zowe

The Linux Foundation’s Open Mainframe Project recently introduced Zowe, an approach designed to bring a graphical web interface to the mainframe for the first time. While it was previously possible to run a Linux operating system with a GUI on a mainframe, IBM’s central zOS mainframe operating system did not have a graphical user interface.
