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.

Increase the maximum size of a LOB object per table or per table partition

SQL and XML limitshttps://www.ibm.com/support/knowledgecenter/SSEPGG_11.1.0/com.ibm.db2.luw.sql.ref.doc/doc/r0001029.html The maximum size of a LOB object of 4 terrabyte leads to the necessity of partitioning the table just due to this limit. Sin...

Add option :statement rollback is able to release the locks for the failed statement.

When -803 ( violating unique key constrain ) happen on a statement, there are two things happen1) db2 still hold the lock on the row accessed by the statement that cause -803 , no matter the statement had fail.2) The transaction was not rollbacked...

Reorg online on 24x7 applications

The reorg online process need to lock the table in order to conclude. This is not a problem when you dont have many transactions, but when you have a 24x7 intense workload you might have a huge impact on your application.

[Copy] Support mixed row/column environments without requiring CUR_COMMIT=ON

We have recently run into a problem when we enable Cur_commit because of the locking behavior expected by some applications (they expect blocking). Therefore, we have to disable CC, but then that app cannot use blu. We want to give our plant the...

Block locking for U/D on MDC when LOCKSIZE=BLOCKINSERT

Block locking is done for INSERTs on MDC tables when LOCKSIZE = BLOCKINSERT, which is a great benefit for memory usage, and allow to parallelize treatments for different dimensions. However, this is unsufficient, because treatments do also Update/...

ITC tables for pureScale
