IBM Db2 - The Ultimate Database for Cloud, Analytics & Mobile
Is maintenance needed in Db2 for z/OS (V11 or V12) for a migration to
- the current hardware z15
- or the current operating system z/OS 2.4 ?
As of today there are no APARs/PTFs needed to tolerate such a migration.

Performance thresholds are not a new concept. They’re easy to understand in principle, but why do people avoid using them? Some users believe that performance thresholds can cause you to react to a quick fix and often make performance worse than when you started. If you’re setting Db2 performance thresholds based on changing application conditions, you are trying to anticipate what is normal and adjust from that. Maybe you ignore using thresholds because they can’t detect the anomalies…Continue

The idea of the traditional data center being centered on relational database technology is quickly evolving. Many new data sources exist today that did not exist as little as 5 years ago. Devices such as active machine sensors on machinery, autos and aircraft, medical sensors, RFIDs as well as social media, and web click through activity are creating tremendous volumes of mostly unstructured data which cannot be…Continue

Sometimes it is useful to generate JCL executable code for //SYSIN via SQL mass operations, e.g. change specific tables from one option to another. If the result row fits into one JCL line with a length of 72, then all is fine. If the line must be split, then the question comes up: How to split?
Here is a solution for commands (like REBIND PACKAGE), SQL (like ALTER TRIGGER) or…Continue
AUTOBIND is a very useful automation instrument inside the Db2 engine.
Suppose you change the definition of the table or index and these changes have impact on the dependent package, the static SQL package is marked as invalid,…Continue

When I joined IDUG as a volunteer a few years ago I was surprised that IDUG were not providing any Db2 education in Latin Amercia. The majority of the events and user group activities were concentrated in North America, Europe and Australia.
As a naive Spanish speaker I had a vision to extend IDUG into Latin Amercia. I am please to inform you that IDUG are hosting two events in Latin Amercia this…Continue

If you think you know all about APPLCOMPAT, then please read this!
Advanced triggers introduced in V12 allow SQL PL statements and this opens “SQL only applications” to triggers. There is reduced need to call a stored procedure,…Continue

A Db2 group buffer pool (GBP) consist of two parts:
1) Directory entries
2) Data entries
For each data entry there must be an associated directory entry in the GBP.
A directory entry can exist without a data entry in the…Continue
With APPLCOMPAT V12R1M504 on e.g. SPUFI or DSNTEP2, one can no longer create segmented or classic partitioned table spaces. See knowledge center for this restriction.
A small marginalia is behind this restriction, if this is combined with another…
