zERT Hints and Tips
IBM z/OS Encryption Readiness Technology (zERT) has given z/OS system programmers and auditors visibility into the cryptographic protection of z/OS TCP/IP and Enterpise Extender connections since z/OS V2R3. zERT data reveals which protocols are being used, which cryptographic algorithms have been selected, what are the key lengths involved, and more. This session will provide a short overview of the zERT capabilities and discuss some of the common questions zERT users have raised before, during and after zERT deployment. Topic areas include: validating zERT configuration, importing and querying data into the zERT Network Analyzer, understanding reasons why sessions might be reported as being unprotected, and more.

Shared Memory Communications V2 - Multiple IP Subnet Support
Shared Memory Communications has been limited to communications within a single IP subnet. SMC Version 2 removes this limitation by providing multiple IP subnet support for both SMC-D and SMC-R. This session will provide a brief introduction and overview of SMCv2, SMC-Dv2, and SMC-Rv2. Additional information will be provided for SMC-Rv2 along with RoCEv2 ("Routable RoCE”) including the IBM z16 and RoCE Express3. SMC-Rv2 uses RoCEv2 technology which uses your existing IP topology and IP routes to extend the reach of RDMA thereby expanding the benefits of SMC-R to additional application workloads. In this session, you will learn how you can define and control the scope of SMCv2 connection eligibility and how to identify potential use cases that could benefit from the savings in network related CPU cost, reduced latency, and increased throughput. Learn how you can unleash SMCv2 in your enterprise!

Understanding and Configuring syslogd
The syslog daemon (syslogd) allows you to capture messages from multiple sources and store them in a central location. The syslog daemon can be configured to collect messages generated locally and forward them to a system where the messages can be consolidated and optionally archived. In this session, you will learn about the different configuration capabilities with the z/OS syslog daemon, and will take an early look at upcoming enhancements to syslogd.
- Time: March 7, 2023 | 9:15 AM - 10:15 AM (EDT)

Sysplex Network Technologies and Considerations
In this session, the speaker will review z/OS Communication Server networking technologies that help maximize the value of the Parallel Sysplex environment. He will discuss recent enhancements in the area of High Availability and workload balancing, including considerations for enabling these features. Topics will also include: • Best practices recommendations for intra-Sysplex connectivity • External connectivity into the Sysplex environment • Techniques for achieving network interface resilience in a flat network • The impacts of using stateful firewalls in the Sysplex access network.

Getting the Most Out of OSA and HiperSockets with z/OS Communications Server
The IBM System Z OSA-Express is a critical aspect of your z/OS application workloads. OSA and HiperSockets are used for both SNA and IP connectivity. In this session, we will focus on how z/OS Communications Server uses OSA for IPv4/IPv6 external connectivity based on the Queued Direct IO (QDIO) architecture. The session will cover the operational aspects of OSA as well as configuration options for optimizing both inbound and outbound network traffic. We will also look at how HiperSockets Converged Interface (HSCI) could be an operational benefit to your environment. The focus will be on the z/OS Communications Server software use of OS. The speaker will also discuss hardware aspects where such aspects are of importance to understanding how the hardware and software combine and cooperate to deliver optimal function and performance.

z/OS Control Plane Appliance for z/OS Containers
A Kubernetes cluster is comprised of two different node types - control plane nodes, where the cluster management occurs, and worker nodes, where the workload deployments run. z/OS Containers will provide the worker nodes where containerized z/OS workloads will be deployed. In this session, you will be introduced to the z/OS Control Plane Appliance, a closed appliance, built on z/OS Containers Extensions technology, that runs in a z/OS system and provides the control plane node. This allows all nodes in a Kubernetes cluster to be fully configured on z/OS systems.

Hybrid Networking for z/OS Containers
Networking in a Kubernetes cluster is a rather large and complicated topic. In this session, you will learn about the different networking infrastructures available in Kubernetes, each providing external access to Pods running in the Kubernetes cluster as well as pod-to-pod communications within the cluster. You will then be introduced to Communications Server's networking support for z/OS Containers, called hybrid networking, that combines the best features of the different Kubernetes networking solutions into a single option.

AT-TLS Hints and Tips
Application Transparent Transport Layer Security (AT-TLS) is one of the most heavily used security features of z/OS Communications Server, but it can sometimes add complexity to an already complex set of technologies like TLS and digital certificates. Come to this session for hints, tips, lessons learned, and best practices regarding AT-TLS deployment and problem diagnosis.

VTAM, SNA, and Enterprise Extender: Status and Future
The Systems Network Architecture (SNA) protocol has been in use in enterprise computing environments for nearly half of a century. Despite rumors of its demise, it is still used to transport a large percentage of mission-critical data around the world. However, it has evolved, and more changes are coming. In this session, the speaker will review some general concepts related to VTAM and the SNA protocol. The current and future viability of SNA will also be discussed.
