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 ideasibm@us.ibm.com for resolution.

Allow Liberty to bind to unix file sockets

Dear community, we do have many applications on a vast number of network interfaces (if/eth) per unix host. In case we need fail-over, we assign multiple ports per application (e.g. 8000, 8001 for application 'a' and 8002 for application 'b'). The same port(s) might be used for other applications on another interface. This way we can select applications by IP/Port or hostname/port. However, we also use IHS as a reverse proxy in front of Liberty Profile. In fact, we only need to bind IHS publicly to use the application. So we asked our unix department how we could bind Liberty to loopback addresses instead. While we would need multiple local (loopback) IPs to match the outgoing IPs (due to port reuse on other interfaces), they asked us if unix sockets were a valid option as well. Hence I am asking for Unix file socket support for both IHS and Liberty to avoid binding to a public interface and creating more loopback/127.x.x.x interfaces. I am not even sure HTTP over unix file sockets is even possible and feasible.

    Thank you for the suggestion. The requirement does have merit, but looking at it with respect to our total backlog of requests we do not see sufficient interest in this enhancement to merit delivery any time in the foreseeable future. Given the unlikelihood that we would deliver this, we are declining the request rather than leaving it in an uncommitted state for an extended period of time. If you would like to discuss this decision further, please contact Graham Charters <charters@uk.ibm.com>.
