IBM Data and AI Ideas Portal for Customers
This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

Thank you for submitting this enhancement request. While we view all the enhancement requests we receive as valuable and we would like to implement all of them, in an effort to have maximum transparency we are closing the ones that don’t currently appear on our two year product roadmap. This is not to say that these enhancements may not still be implemented at some point in the future as we do evaluate our requirements on the basis of customer demand and technical impact, to deliver maximum value to our customers.
We appreciate your input to the Db2 for z/OS development team. And we hope that you will continue to submit enhancement suggestions for improvements as customer feedback is a key component to shaping the future direction of Db2 for z/OS.
Sincerely,
The Db2 for z/OS Team
I believe it would be very useful to know when a dictionary was created.
Suppose you define a partition (or TS) and a dictionary is created day1. You have regular REORGs scheduled, but they are all coded with KEEPDICTIONARY. Some things that could happen that might require (or benefit from) a newly-defined dictionary include:
1) Data changed via SQL or utility such that the characteristics of the data has changed enough so that a new(er) dictionary would result in better compression.
2) Application of DB2 maintenance that might include changes to the (default) compression algorithm.
We have a UTS PBR TS with appx. 200 partitions. I noticed that the most recent partitions (heaviest DML activity, partitioned on a key that is date-related) have the worst compression ratio of all the preceding parts. I was curious to determine the date those dictionaries were created.
