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).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:


Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,


Post your ideas

Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,

Better tool for performance analysis and tips

Until now, we can use the tool "explain" to have a query plan generated or use "onmode -Y" for 
the same purpose. Next, we can use onstat indicators or SMI queries to mearure performance.

Anyway, this has downsides:
- You have to know the query for "explain" or the session for "onmode -Y" to work. Sometimes it is not clear how to determine that.
- Most of the output is rather cyrptic. It is not always clear if the query has a problem or needs tuning. For procedures, it can be
even more time-consuming.

We now competitors exist who offer a solution to provide more proactive performance measuring without 
having to set up a bunch of monitoring queries. Even some open source competitors offer such featues.

They do this by 
- storing the statistics and query plans in a snapshot like manner
- comparing them when asked to derive performance issues
- creating a hypothetical index to test if a real one would be worthwile
- presenting a report with findings and possible solutions 
    (e.g. index missing, index not used by query, statistics missing, query took a lot of time compared to before, storage performance poor, bottlenecks and so on)

We do not ask for a replica, but a reimagination of features alike. Maybe it can be built into IFX HQ.
