How to discover incompatible changes
Webinar präsentiert von SEGUS & SOFTWARE ENGINEERING (Engl)
|The what and why of ICIs (15 min.)|
If you’ve been paying close attention, you will have noticed that over the course of the past couple releases of DB2 for z/OS, IBM has been making changes that can modify the behavior of your DB2 application programs. The number of incompatible changes being introduced by IBM started off slowly in DB2 9 but has grown to a significant number today. So much so that there are ways to trace incompatible changes (using IFCIDs and ICIs, or Incompatible Change Indicators), as well as methods to repress the changes, even if only for a period of time.
|Ways to deal with incompatibilities (15 min.)|
This session will discuss the incompatible changes, their potential impact on your applications, as well as provide guidance on how to tackle the whole experience. And you’ll also see how SEG’s Workload Expert technology makes it easier to manage and control these incompatible changes. With all of this information at your disposal, you can make sure that your DB2 applications do not wind up in the ICU (intensive care unit)!
|Customer experiences (9 min.)|
Now that we all know everything about ICI’s, let us have a look at how the separatly licensable BIF/ICI Use Case of WorkloadExpert can help you find where the “bad guys” are and how to continuously check that everything is ok. This presentation will show how you can find out ICI Details for static and dynamic SQL, and then we will show real customer results from a “BiF hunt”.
|1. You talked a lot about built-in functions and how they are changing causing incompatibilities, but can you give us another example?|
|2. What best practices would you recommend for dealing with incompatible DB2 changes as we move forward?|
|3. I know the version twelve is around (DB2 12), Are there new ICIs in it?|
|4. Is BIF/ICI Detection free trial really difficult to install and start using it?|
