Db2 for LUW

Ferdinand Prahst, ITGAIN Consulting Gesellschaft für IT-Beratung mbH

IBM Champion 

Maintenance is one of the oldest but still one of the most important parts of a DBAs work. Tools like Ansible and AWX can help the Admin (or, in case of DevOps, the Devs) to leverage their daily work and manage even a high amount of systems with ease. This session will include info about basic architecture and workflow of Ansible and AWX; integration options with Db2 (unix only); a complete backup, reorg and runstats playbook and job template; and give examples for other usecases with Db2.

What goes on in the package cache is often a mystery. Performance of SQL can be dramatically impacted by the package cache, so understanding how it works is very important. Newly added in 11.5 are details about SQL failures.

Even with the most sophisticated self-tuning and self-administering database, it is still useful to have it checked over. Technology is becoming increasingly more adept at examining itself, recommending improvements, and highlighting potential problems long before they become an issue. But would you still fly on an airliner that was never serviced and had not flagged problems to the ground crew when they thought they should? Whether your database is on-premise, in the cloud, or a hybrid, an examination of its configuration, design and performance is highly advisable. With the combined expertise of over a century of Db2 knowledge, we’ve encapsulated the most critical and some of the more esoteric issues into a single Jupyter Notebook, allowing your database to be given a health-check wherever it resides and whatever it does.

Even in an ever expanding Ansible universe with lots of available models, you get into situations when the call of an external script (shell, Perl, Python) is the way to achieve your goal. Maybe you already have a scripted solution ready, but you want to integrate it with Ansible. This presentation shows some obstacles and how to avoid them by keeping your Ansible role self-aware and by optimizing your output for human reception. We will have a look into what the complex data structure and the shell module provide as a result set and how it can affect memory consumption and performance when running multiple tasks against multiple Db2 servers.

The prologue of this feature debuted as Technical Preview in Db2 V11.5.4.0 where introduction of Pacemaker as the new "cluster manager of choice" was announced. Act One followed five months later in Db2 V11.5.5.0 with production level support of 2-node HADR configuration on Linux. Integrated bundling and installation of Pacemaker anchored Act Two in the ensuing V11.5.6.0 release around mid 2021 to enhance up & running experience, along with other valued features added. The Third Act serves as the climax of the entire journey where it intends to cover other popular type of HA configurations while adding other improvements. We will cover details on 2-node Active/Passive with file system failover, mount point monitoring, quorum enhancements, as well as alternate configurations on cloud deployment. Finally, we'll provide a sneak peek at our road to the final chapter.

One of the most important factors in query performance is the access plan chosen by the Db2 query optimizer. Understanding the query access plan is essential to understanding query performance and the explain facility is the way to get the access plan. But SQL statements can be issued in different ways (dynamic, static, procedures, application programs) and access plans can exist in a variety of contexts (system catalogs, dynamic statement cache, monitoring tables). So getting the correct access plan for the correct statement can sometimes be a challenge. This presentation will cover the most important techniques for collecting and using explain information so that you can quickly and effectively understand your access plans in order to achieve and maintain the best possible query performance.

Learn the process for how Db2 addresses security vulnerabilities, to read and understand a security bulletin, and to be in a better position to respond when fixpacks and special builds are released. Security vulnerabilities are a current fact of life with software. Db2 participates in an IBM process known as the Product Security Incident Response Team (PSIRT), which is responsible for fixing and disclosing security vulnerabilities. Communication of these issues to customers is done through security bulletins, which are often obscure and confusing. This presentation will lift some of the fog surrounding the process and make the security bulletins easier to understand. The topic of timelines for fixes will also be discussed.
