IBM Data and AI Ideas Portal for Customers

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:

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,

  1. Post an idea

  2. Upvote ideas that matter most to you

  3. Get feedback from the IBM team to refine your idea

Help IBM prioritize your ideas and requests

The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.

Receive notification on the decision

Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

Insert data to PERF efficiently in bulk (executemany() method in Oracle)

We are using PLC service in Symphony 6.1.1 to insert data to PERF db in Oracle. We noticed that PLC is inserting data to Oracle inefficiently record-by-record, using execute() for each record insert.
We did some experiments and measurements which show that execute() takes around 130 seconds to insert 1000 rows to our Oracle server, while it takes <1 second to insert 1000 rows using executemany() method.
We would like PLC to leverage executemany() method to improve data insertion performance in bulk.

    Provided a trial fix (defect - perf recovery extremely slow) as well as instrument code measuring time cost by batch inserting records.
