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.

DB2 unable to detect dead network card on server when setting registry variable DB2TCP_CLIENT_KEEPALIVE_TIMEOUT. Since it does not detect the dead network card, this prevents automatic client re-route from starting. Problem is specific to Linux platform.

Workaround: Manually tune Linux keepalive TCP/IP kernel parms, however this will affect all applications on the system. DB2 should be able to tune keepalive values so it can quickly detect dead NIC on server side. Oracle has this capability. Linux kernel introduced TCP/IP socket parameter TCP_USER_TIMEOUT in kernel 3.10 to implement functionality for DB2 to tune these parameters at application level instead of system level.

Please add DB2 support for TCP_USER_TIMEOUT so it can detect dead NIC on server side without affecting other applications on same system.
