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.

db2pd command to report exact operation that causes HADR replay only window

Currently only "Replay only window is active" is reported in db2diag.log, but not the detailed information about the operation that causes the replay only window, such as exact DDL, reorg, runstats, and etc. statements.

Support for minimally logged indexes on HADR-enabled databases

Provide ability to create non-logged (or minimally logged) indexes on HADR-enabled databases such that they get created on the standby databases as well.

Allow Read Only Sharing on HADR while Catalog updates

We are trying to use HADR Read only Sharing to allow ad-hoc query against a 4Tb transactional database. The standby should allow us to reduce the impact of ah-hoc business queries.The application is a vendor supplied document storage and retrieval...

Improve HADR standby replay performance

a)HADR replay master contends with replay worker on queue, and lots of latch contention were observed.b)HADR replay has IO performance issue. Lots of random IOs were observed, and there should be some sort of prefetch IO to improve performance.

Kind of db2iauto for HADR

In the same way db2iauto starts instance once the server is rebooted, the HADR should restart also automatically.Actually, when server is rebooted, the instance is started but the HADR starts to be desynchronized.

Manually confirm whether to switch before TSAMP+HADR automatically switches

In the TSAMP+hadr environment, in the event of a failure, TSAMP will directly switch the active/standby relationship. Sometimes, it may solve the A machine failure recovery time, especially the AB machine transmits a large transaction log.Therefor...

TSA - Not scalable

TSA Does not Scale, with each database added it consumes 5 - 8% CPU.In our system ZLinux this is the only option we have for auto failover. When we have 10 Databases we are now consuming 50 - 80% CPU just to run TSA and having to pay extra licensi...

BACKUP Performance: Incremental and Delta backups should not have to read all tablespace pages.(RIMS)

Backup currently reads ALL pages in the tablespace to examine the pageLSN in order to determine if a page should be included in the image. This is poor for performance, customer want this addressed using a 21th century approach.

IBM db2 UDB . total number of standby supported in HADR needs to increase it from 3 to more value like datagaurad in oracle

Currently HADR setup support maximum 4 standby including one principle . Why can't it goes like data gaurd in Oracle which support 30 standby

Improving the DBD management design

We had a Db2 load job run that used a load control dataset with 1,764 “INTO TABLE” statements run against a database that had one tablespace with 1,366 tables having 1,306 indexes. The DBD length = 2628728. When the job was run, the SYSDBDXA ...
