7th csDUG Conference: A great success!

The 7th csDUG Conference happened a few days ago (10/10/2019) in Prague.

Last year, we added a third track for IMS for z/OS users. This track was full this year! The traditional 2 Db2 tracks (Database Administrators and Database Developers) were also well attended. Some 60 Db2 and/or IMS users, mainly from Czech Republic and Slovakia, joined the conference this year. The event was sponsored by Broadcom, and held in the Broadcom R&Ds lab in Prague. Thanks to all the speakers who made the trip to share their expertise and give presentations about Db2 for z/OS and IMS.

A few pictures from the event!

Zowe: Making the Mainframe easy to work with, just like any other platform

The IBM System Z server (Mainframe) is the system of record for most Fortune 1000 companies, housing critical business data as well as PII data from customers that must be available at all times but cannot be compromised. The Mainframe platform is behind just about every critical user experience in business today. For this reason, every company shares common concerns about the security of their customer data and the compatibility and performance of the applications that drive their business.

What is Zowe?
Zowe is an open source project for the Mainframe. Alike Mac OS or Windows, Zowe comes with a set of APIs and OS capabilities that application developers can leverage. Zowe also includes some application samples and applications out of the box.
To learn more about Zowe, check out this 5 minutes YouTube Video:

And Zowe is evolving at a fast pace! Check out the online Release Notes: Since its initial release in February 2019, there has been new updates every month.

Zowe main components

Zowe Application Framework: A web user interface (UI) that provides a virtual desktop containing a number of apps allowing access to z/OS function. Base Zowe includes apps for traditional access such as a 3270 terminal and a VT Terminal, as well as an editor and explorers for working with JES, MVS Data Sets and Unix System Services.
API Mediation Layer: Provides a gateway that acts as a reverse proxy for z/OS services, together with a catalog of REST APIs and a dynamic discovery capability. Base Zowe provides core services for working with MVS Data Sets, JES, as well as working with z/OSMF REST APIs. The API Mediation Layer also provides a framework for Single Sign On (SSO).
Zowe CLI: Provides a command-line interface that lets you interact with the mainframe remotely and use common tools such as Integrated Development Environments (IDEs), shell commands, bash scripts, and build tools for mainframe development. It provides a set of utilities and services for application developers that want to become efficient in supporting and building z/OS applications quickly. The CLI provides a core set of commands for working with data sets, USS, JES, as well as issuing TSO and console commands.

Where to start?
The installation of Zowe™ consists of two independent processes:
  1. installing Zowe runtime on z/OS 
    • Install the Zowe Application Framework, the API Mediation Layer, and a number of micro services that provide capability to both.
    • Install the Zowe Cross Memory Server. This is an authorized server application that provides privileged services to Zowe in a secure manner.
  2. installing Zowe CLI on your computer (The Zowe CLI is not installed on z/OS and runs on a personal computer)

Top 5 moments from IDUG 2019 Charlotte

IDUG is certainly an invaluable occasion for Db2 professionals to regroup, socialize, network, and get some premium education about this Database Management System. IDUG is actually more than a group of people, it’s a real community of professionals who meet to help each other with the business challenges they face in their daily jobs.

Just saying, the Data in Db2 tables across the globe are critical for most Fortune 1000, and thus the world’s economy is dependent on Db2 availability, performance, recoverability, and security. IDUG helps those professionals working on Db2 (SYSPROGs, Database Administrators, Application Developers …) to maintain their skills to stay up for this challenge!

IDUG announced the location of next year Conference: Dallas !

IDUG Expo opening:
 Broadcom brought a NASCAR into their booth,
 and a legendary NASCAR Driver (Michael Waltrip)
