Taming Python and Db2 for z/OS

Jørn Thyssen, Principal Solutions Advisor, IBM z Data and AI

Python is a very popular language for business applications, machine learning and infrastructure provisioning, such as ansible. In this presentation we will show how to configure and install the ibm-db plugin to work with Db2 for z/OS on all platforms. We will also explore examples of DBA and sysprog productivity aid programs using various python libraries to run a Db2 query and save in Excel format; run a Db2 REORG; run Visual Explain; create a set of explain tables; and much more.

10:00 - 11:00 AM CST

Now You See It, with DB2 AI for z/OS 1.5

Akiko Hoshikawa, Distinguished Engineer in IBM Data and AI

Db2 AI for z/OS continues to evolve to provide operational intelligence in Db2. The session covers the quick overview of the product and the updates in Db2ZAI 1.5. 

Db2ZAI 1.5 exploits remote connection statistics to provide the insights that you had not been able to see before, such as: which userid is contributing to DBATs or its thread attributes. The Db2ZAI profile recommendation generates filtering based on client user-id or application name in addition to IP address.  Db2ZAI 1.5 also exploits aggregated accounting information to present the clear performance information - where the time spent in Db2, based on SME experience.

11:00 – Noon CST

Multi-Table Tablespace to Single-Table Tablespace PBG – 4 Techniques

Todd Mollenhauer, Technical Consultant

Multi-Table Tablespace deprecation is still on many Db2 shop’s TO-DO list.  The conversion process requires lots of DBA time and effort, even with improvements to the process with FL508 (MOVE TABLE). 

In the session we’ll look at the following 4 techniques to convert Multi-Table Tablespace (MTTS) to Single-Table Tablespace(STTS) PBG. 

1.     ‘Classic’ – Create STTS PBG, Drop, Unload, Create Tables into new PBG, Load data, Runstats, Rebind 2.     Move Table – Available with FL508
3.     Create temp copy of Tables into new PBG, SQL INSERT operation to move data, then rename tables to convert.
4.     BMC Change Manager DML to identify and create all DDL and Utilities to execute ‘classic’ or Move Table process.

For each technique we’ll explore:

  •  Process flow
  •  Pros and Cons
  •  DBA time and conversion efforts

Noon - 1:00pm CST

Getting Ready for DB2 13

John Lyle, Senior Software Engineer and PDM Team Lead

The purpose of this presentation is to introduce the new migration process for the new Db2 13 for z/OS release. The Db2 13 release migration process is significantly different from any previous Db2 release migration. The changes are, in fact, revolutionary. We will detail the Db2 12 to Db2 13 migration process, the Db2 13 Installation process, and go into details regarding application compatibility and the Continuous Delivery process as it relates to Db2 13. Each release brings new migration processes and challenges we will detail the nuts and bolts of the significant Db2 13 process and procedure changes.      

1:00pm - 2:00 pm CST
