Abstracts:

Query Optimization in Relational Databases – Why it Matters!

From the early days of SQL, we have advertised that the user specifies the “what” without worrying about the “how” - query optimization takes care of that.
A lot has changed since the early days of RDBMS. SQL queries are more complex. The amount of data has grown exponentially and the service level expectations have become tighter. What was good then is simply not acceptable today.
In this session, we will provide a glimpse into some of the challenges and how some of the leading RDBMS (DB2, Oracle) are addressing them. We will discuss what the future of query optimization may look like and why “perfect” may not be attainable.

Objective 1: Fundamentals of query optimization
Objective 2: Major challenges
Objective 3: Recent improvements – DB2, Oracle
Objective 4: What might the future hold?
Objective 5: Is a perfect access path even possible?

My Favorite SQL Features in DB2 for z/OS V11 and V12
This presentation provides an in-depth look at the top DB2 for z/OS V11 and V12 SQL features.  We present a clear and detailed explanation of each feature showing how you can use this feature in your shop and explain how you will benefit from these enhancements.  We will not just scratch the surface but take a deep dive into features most important to you as a developer and a DBA.

5 Bullet Points

DB2 12 Continuous Delivery – New challenges for deployment
Short Presentation Abstract:
Starting with version 12, DB2 goes agile and code fixes, as well as new features and functions will be delivered in a continuous stream, so called Continuous Delivery. While this change intends to make new technology available faster than in a three-year cycle it’ll also affects the way we did DB2 migration and testing before. This presentation provides an overview about DB2 Levels and how they affect the DB2 subsystem, the Catalog/Directory, SQL and DDL. More importantly, I’ll show how changes can be applied safely and what levels of quality assurance and testing can be passed to assure Continuous Delivery goes well with Continuous Availability.
Full Presentation Abstract:
Fundamental changes in the DB2 z world often lead to concerns. Let’s face it – some changes force us to change! While a DB2 version migration usually took months, or even years, there will be no new DB2 version after 12, but continuous code drops. This will have a tremendous impact on migration strategies, because we have to find a reliable way to test these code deliveries in a fraction of time. If we make it, Business Divisions will become enthused at how quickly new technology becomes available for new applications. This presentation will describe the difference between Code, Catalog, Function and Application Levels, how you can control them and how you can fallback in case of anomalies. It also illustrates how we still can be pro-active in testing without burning weeks and months.
Learn how to choose from four different levels of testing and a new way of automation. CD-Screening allows you to pick and choose from KPI based test automation. The levels include simple anomaly alerting, access path verification, clone Pre-apply and even workload capture/replay to easily discover different behavior resulting from a new code level. Joining this presentation, you’ll learn how to align Continuous Delivery to your Continuous Availability.
Presentation Outline:
1 – Agile, Continuous Delivery, DevOps – just buzz words, or new methodologies?
2 – DB2 Code, Catalog, Function and Application Levels – differences and dependencies.
3 – Activation/Deactivation of new code and how to fallback and when you can’t.
4 – Different flavors of (pro-active) CD-Screening and how it can be automated.
           -Anomaly alerting based on Incompatibility Change Indicators (ICIs)

-Dyn./Stat.Access Path Change Detection e.g.via Plan Management

-Clone based code change pre-apply exploiting Backup System

-Workload-KPI verification using SQL replay and KPI comparison
5 – Conclusion – looking back at BIF Compatibility, APPLCOMPAT and how it may develop.

Connecting Applications Including Mobile and Cloud with DB2 for z/OS using REST
Although z Systems provides unmatched scalability, security and availability for valuable data, applications have to be able to get to that data. Applications also must be able to access the data from a variety of front-end layers, including cloud and mobile. In this session, you learn about the new DB2 z/OS REST service feature available in DB2 for z/OS 11 and 12. The new DB2 z/OS REST feature leverages the existing distributed data facility (DDF) capability. It provides the same class of services you expect when using DDF to access DB2 data. This includes authentication, authorization, client information, enclave classification, system profiling, sysplex awareness, accounting; statistics, displays, and monitoring which are fully integrated into existing DB2 facilities. The new REST feature will also be demonstrated to show how easily REST is to use with DB2 z/OS. Included in this presentation is how to use z/OS Connect EE for your DB2 data and how to configure DB2 related APIs.
