Fast copies of Db2 for z/OS tables are increasingly difficult as newer features add structural complexity. Table versioning, partition growth and rotation, XML and LOB data, temporal and archive relationships, and deferred VSAM creation can prevent direct dataset-level copies and force slower fallback methods. This webinar explains the key challenges and what they mean for copy speed and reliability.

This session should be considered because it addresses a high-value challenge for Db2 customers: performing a version upgrade with little to no application outage while preserving a reliable backout path. Based on real production experience, it covers failed upgrade scenarios, post-upgrade risk, and the operational realities of switching active workloads across versions and hardware. Rather than staying conceptual, it presents a practical, repeatable approach using Q Replication and Automatic Client Reroute (ACR), along with lessons learned on synchronization, clustered cutover behavior, and risk reduction. Attendees will leave with actionable ideas they can apply in their own environments.
This session presents a practical approach for performing a no-outage Db2 version upgrade using Q Replication and Automatic Client Reroute (ACR). It explains the drivers behind the solution, including online upgrade capabilities in competing platforms, prior failed upgrade attempts, and the need for a reliable backout strategy. The session then walks through replication setup, synchronization of an active source to the target, online cutover steps, and operational challenges in clustered environments. Attendees will learn how to move from an older Db2 version to a newer one with minimal disruption and lower upgrade risk.

The Db2 family of products including Db2, Db2 Warehouse, and Db2 PureScale provide a number of important features for diagnosing and solving your SQL problems. Through a series of practical examples, this session will bring you up speed on the latest capabilities available for SQL diagnostics and show you how you can leverage them to solve query problems in your own environment. You will learn how to identify your most expensive SQL statements using the package cache table functions, and how to use Db2's "time spent" metrics to analyze where your problem queries are spending their time. You will also learn some new tips for monitoring sort memory metrics and query memory consumption in order to tune your analytic workloads. Finally you will learn how to use the runtime explain capabilities in conjunction with the activity event monitor to capture actual query plan cardinalities as well the per object metrics.

In this session, we will introduce a z/OS middleware configuration tool (zconfig), which is an automation tool that in a very intuitive way, will help you to discover the configuration parameters of any of your Db2 subsystems. Additionally, you will be able to provision new Db2 subsystems with a configuration like the one just discovered.
Bringing configuration-as-code and automation to Db2 for z/OS environments modernize how to perform operational processes towards your Db2 subsystem management.
Join this session to learn practical approaches to modernizing your Db2 subsystem management.

Db2 Z and the CIA is a powerful informational combination. To be clear, the CIA is the Compliance Information Analysis product available for free to many users of Db2 Z (if you have Broadcom products). Broadcom introduced the CIA as a subproduct of ACF2. It is now an independent product available to most users of their products. The CIA provides a series of Db2 tables that can contain all the information from your external-security-manager (ESM), whether it is ACF2, RACF, or TopSecret. Once your ESM is loaded into the CIA, it is relatively more accessible to the curious end-user! SQL SELECT can be used to easily build interesting and useful and focused reports about your security configuration. This presentation will go over the basics of mainframe security and the basics of the CIA and how to build and populate. Finally, interesting CIA tables and views (and sample SELECTs) will be highlighted to show why it is useful.

Most IT experts know the catchphrase “Never change a running system” very well, especially once you experience that a small change can have a significant impact. Anyway, “The only constant is change” is very true as well. Even if we don’t touch an application for enhancements, we’ll face security updates, software updates, hardware updates, configuration changes and data growth.
Before moving to a new machine, applying (Db2) APARs, changing schema, or SQL, it’s common to test in a sand-box, or development system – very good, but here come the challenges:
1st There are quite a few regulations that affect reliable testing of changes and they all have one in common – DON’T USE PRODUCTION DATA!!!
2nd Without real data, or with data masked and sanitized, we’ll very likely see different results than running one and the same query in production.
This session explains how you can reliably, and resource-friendly, simulate your entire production environment, WITHOUT production data and even on a different machine.
We’ll cover prescreening changes in the following areas:

environment changes, like upgrading to a new machine, or adding more resources
application changes, like SQL queries and schema
data changes, like amount and distribution

The capabilities introduce a whole new world of "what if" opportunities and especially protect you from testing that doesn’t focus on what counts: the resulting performance in your production environment.

Db2 delivers a wide range of tools for problem determination. Those tools range from the new Log Analysis Capability in IBM Db2 Genius Hub to classical tools that can and should be used for deeper analysis. As the Db2 community constantly welcomes new database administrators and application developers, an effecient tooling and its use is required for those new community mambers. The session will share tools and best practices for the first occurrence data capture (FODC) tools available for DBAs and developers. This session will cover the first steps in the process of problem determination and problem source identification (PD/PSI). It provides hands-on and practical examples for the strategy and process to encircle and find problems by asking the right questions.
