IBM Data and AI Ideas Portal for Clients

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

If you have not registered on this portal please register at http://ibm.biz/IBM-Data-and-AI-Portal-Register . To complete registration you will need to open the email you will receive from Aha to confirm your identity.

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 offering manager 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.

Add configurable per session/per PDQ thread log cache similar to Sybase user log cache.

For high volume environments OLTP environments e.g. thousands of sessions and HDR/RSS nodes add a per session/PDQ thread log cache. This is flushed to the physical and logical log buffers either when full or at transaction commit time.

Who would benefit from this IDEA? Customers with very high volume OLTP environments.
How should it work?

A new onconfig parameter PRIVATELOGBUFF to control the size of the per session/PDQ worker log buffer.

Contention for the logical log buffer latch would be greatly reduced in very high volume OLTP environments e.g. those with thousands of sessions and HDR/RSS nodes. Especially when trying to reduce replication latency where the logical log latches are important.

Idea Priority High
Priority Justification Allowing large increase in number of application processing sessions to improve performance.
