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.

Automate restart of IIDR tasks when RRS terminates

We had issues with RRS recently which were solved via a maintenance cycle. During those issues, our IIDR Capture and Apply tasks failed and required manual restart. We have the option TERM=N enabled yet the Capture/Apply tasks were not restarted w...

Leverage "FOR EACH ROW ON UPDATE" functionality to maintain Peer to Peer Version Columns, instead of triggers

Current implementation of Peer to Peer Version Columns (IBMQREPVERTIME and IBMQREPVERNODE) depend on BEFORE INSERT and BEFORE UPDATE triggers to maintain transaction information for conflict_action of V (last transaction wins). The use of these tr...

ALTER table DATA CAPTURE NONE not detected by IIDR QREP or CDC

If 'ALTER table DATA CAPTURE NONE' is executed against a table that is actively replicating, any changes made to the source data will not be captured or replicated until ‘ALTER table DATA CAPTURE CHANGES' is executed. This would cause the target...

QREP DDL replication, add UNICODE factor for column length

When replicating from non-unicode to unicode, the legth of char/varchar target columns needs to be extended. Example: create all CHAR/VARCHAR columns at the target with source_length*2 and implemented an additional life belt with OKSQLSTATES = 220...
