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.

Add the hidden attribute for index

我们希望给索引添加一个属性visible on/off比如:ALTER INDEX VISIBLE ON (默认属性)ALTER INDEX VISIBLE OFF (索引不可见)当索引不可见以后优化器无法使用不可见的索引,如果需要,直接alter index...

Increase the number of REORG-recommended operations allowed before a full offline reorg must be performed

The current documentations in v11.5 indicate that only 3 units of work containing REORG-recommended operations are allowed.https://www.ibm.com/support/knowledgecenter/SSEPGG_11.5.0/com.ibm.db2.luw.sql.ref.doc/doc/r0000888.html"There can be up to t...

Detect corrupted synopsis tables online

There is a need to report all corrupted synopsis tables online.Currently, db2dart /crs can do it per table and it's done offline.

Index for a subset of rows

Possibility to index only specific rows of one or more columns. This could be implemented with a WHERE clause in the index create statement and would rsult in a tiny index for exactly the rows you are interested in.

Excessive DBHEAP by BLU compression dictionaries

In current design, when SQL statement accesses a table, the compression and expansion dictionaries of that table will be read into DBHEAP and kept there until database deactivation. For column-based table, the memory consumption may up to 100MB. i...

Enable compression for LOBs that are not inline

Customer would like non-inline LOBS to also be compressed, as inline LOBs can currently be. Many other datatypes can be compressed and there are many large (up to 20MB) LOBs that are stored outside the table that would not eat up so much space if...

Real global CGTT (not SESSION local)

SAP BW needs to materialize data into persistent (regular) tables to be able to access it from multiple session (connections). CGTT and DGTT in Db2 cannot be accessed from multiple sessions/connections. Therefore those temp tables that don't requi...

Make online REORG respect UTIL_IMPAT_LIM

Currently, an online REORG will run as fast as it can (but I think limited to a single thread).It would useful if we made it respect the utility throttling limit that we have in place for other types of maintenance activities (runstats, backup, re...

Parallel Classic Reorg on a partitioned table

Many DBA want to run multiple partitions in partitioned table.at a same time Serial execution takes too long time, it is not really efficient.

Support synchronous detachment of a table partition

Starting with DB2 9.7(?) the detachment of table partitions is handled asynchonously. To simulate synchronous behaviour a complicated work around has to be put in place. Such a behavior could be triggered by a new DML keyword such as ASYNC.
