Session Evaluation

Mainframes continue to serve as the foundation of enterprise computing, powering critical applications across industries. However, understanding transaction flows and the interfaces and protocols in play can be a daunting task.

In this introductory session, we will unravel the complexity of mainframe application architectures, guiding attendees through typical transaction flows and the extensive web of communication pathways within z/OS environments. From subsystems like CICS and IMS to gateways and APIs, we will uncover how these components interact to execute transactions with speed, reliability, and scalability. You will gain insights into how the data flows through message queues, adapters, bridges, networks, tasks, attachment facilities and databases, and learn the foundational communication methods that tie these components together.

Whether you are an architect, developer, or IT leader, this session will equip you with essential insights into mainframe connectivity and transaction processing. Join us to dive into the inner mechanics of mainframe computing and strengthen your foundational knowledge of the mainframe as a mission-critical platform.

Certificates play an important part of ensuring that client server communication to and from z/OS takes place in a way that ensures secure data transport with both parties knowing that the other one is who they claim to be. It's not just about public private keys however, there are certificate authorities, trust roots, subject alternate names, extended key usage attributes, keyrings, keystores, enterprise security managers, x509 and .SSHID authentication, and more.
This talk will cover scenarios that matter to z/OS sites, such as using certs to replace userID/password login. Creating server side certificates from bottom up and having clients trust them, as well as taking externally issued certificates top down and gaining z/OS environment’s trust. In my experience with z/OS customers big and small, whether working with new to Z or experienced sysprogs, many folks get stuck with difficult to diagnose and fix issues where the resolution is around how TLS and SSH handshaking occurs when certificates are in play. This talk is designed to cover the most common ones as well as provide background to help folks understand the moving parts and hopefully avoid getting any in their own environments !

 What if you could skip JCL and use Python for your everyday tasks, forget about ISPF and use just a command line interface and leverage standard tooling and languages to maintain and develop on your mainframe environment. Optimize the use of the transparency layers in your hybrid cloud environment and make your data accesible and your infrastructure consumable. This session will showcase the easy of using several IDE’ s, Tooling, Frameworks, and programming languages which use can use on a mainframe environment.

According to IBM’s annual “Cost of a Data Breach Report 2023”, conducted in collaboration with the Ponemon Institute, the prevalence of data breaches, along with their associated cost, continues to rise year-by-year.
These data breaches are absolutely preventable, if the right practices and policies are put inplace.
So what can you do to mitigate the risks, to understand the danger of APTs, and to stay vigilant when Hackers attempt a breach?
- Attend this session to find out!
This presentation covers overall Cybersecurity Principles as well as some efforts that you can
make on an IBM Mainframe via RACF.

As Mainframe customers are creating third copies, untouchable copies or offload Data to the cloud is it still relevant to know what is going on, on your Tapes and Disks?
Or contrarily you must make sure you are capable of reporting on these devices because of regulations? Tape and disk space becomes cheaper and cheaper. Why should you still be capable of mapping the usage to applications, business units or even users? I would like to get your opinion and experience on this topic and share with you, what we learned from our customers.
