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

Start by posting 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 offering manager 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 a 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.

If you encounter any issues accessing the Ideas portals, please send email describing the issue to for resolution.

TLS 1.3 support with TLS 1.2 fallback

We need in tWAS 8.5.5 support for TLS 1.3 as well as TLS 1.2 for a fallback option.

Idea priority High
Use Case
We have a ND setup of tWAS with a number of peer connections. Not all of them will have TLS 1.3 capabilities at the same time. So we need to connect with TLS 1.3 where possible and with TLS 1.2 at other connections.

    Is there anything I could also consider in due consideration to this. I continue to observe the floatation on this inspite of environmental priorities. Didn't realise until this morning, this was moved to Idea Portal from the list of prioritized RFE from previous year.

    It is imperative that a multiple JVMs within a WAS cell can use both TLS 1.3 SSL protocol with a 'fallback' capability to TLS 1.2

    the current implementation approach recommended by IBM (as per and ) should enhanced as is it is unusable for a cell with a large number of nodes.

    Agreed that backward compatibility is a top priority.
