09:00 - 16:00		 European SQLAdria Seminar – Vodice 2023 DevOps meets Db2 for z/OS application, the bigger picture….

DevOps is a topic that can touches many different areas of the IT processes related to development, implementation and management of applications. The benefits of applying established DevOps techniques are well known by now. Yet, implementing them can be overwhelming. Where to start? What to do next? What will give me "the biggest bang for my kuna Euro…". In this seminar we will discuss several different areas of the lifecycle of  Db2 for z/OS application. We will have focus on Schema and Application build, various types of testing and deployment.
14 June 2023
12:30 - 13:15		 European SQLAdria Seminar – Vodice 2023 Explain explained. What is explain telling me and how to optimize

SQL is a very powerful language. To support it the Db2 optimizer has many ways to get to the data and combine partial results into the final result set. even though many tools are available to visualize the access path Db2 plans to execute, the output can be complex to understand. Breaking it down to the basic elements and understanding the way data is accessed by those elements will enable less experienced developers and DBA's to find performance problems quickly.
13 June 2023
15:00 - 15:45		 European SQLAdria Seminar – Vodice 2023 Get Cozy with Ansible on z/OS

Ansible is a powerful and widely used tool to automate management of various systems including z/OS. This presentation will introduce Ansible to the audience and walk through the z/OS related components. We will learn what it takes to set it up on both server and client sides. And finally will explore and demonstrate how Db2 for z/OS management can be simplified and automated with Ansible.
13 June 2022
15:00 - 16:00		 European SQLAdria Seminar – Vodice 2022 Get Cozy with Access Path Management in Db2 for z/OS

An access path selected by Db2 drastically affects how well or how badly your SQL statement and overall application perform. Developers should be familiar with what the access path is and how to read it, while database administrators need to be able to maintain workload stability avoiding performance degradations and resource consumption spikes. This session will talk about how to interpret an access path with EXPLAINs, discuss how to influence the optimizer, and cover the ways to maintain and manage access paths for both static and dynamic SQL statements

16:00 - 17:00		 Hands-on experience using z/OSMF with Db2 for z/OS

While IBM z/OS Management Facility (z/OSMF) is a core z/OS component since version 2.1, still not everybody is familiar what it is and how it would help with system and database management. In this session we will focus on how Db2 users could use z/OSMF workflows to simplify and automate some of common Db2 tasks. We will also cover what Zowe (mainframe open source project) has to offer for working with z/OSMF workflows.

DB2 tracing is one of the strongest, but least understood, mechanisms that is out there to answer exactly these questions. In this presentation you will get a solid understanding of DB2 instrumentation facility, you will be guided through the variety of DB2 traces and learn how they would help to address system monitoring and tuning challenges.

Applications often rely on a Database to manipulate data, typically using SQL statements. DB2 for z/OS is one of those databases; one of the most robust, reliable and secure for that matter. However, Application Developers need to keep in mind that DB2 for z/OS has its SQL specificities. For instance, the SQL available in DB2 for z/OS is compliant with SQL:2003 standard. What does it exactly mean? What IBM is doing to raise the level of the DB2 SQL to later standards? How does this affect Application Developers – ever heard of APPLCOMPAT? What are the new SQL capabilities introduced in DB2 over the years? Is there something new in this area when using DB2 10 or DB2 11?
In this session, you will learn about :
  • Incompatible SQL changes in DB2 for z/OS
  • How to address incompatible SQL changes  
  • New SQL capabilities in DB2 for z/OS
