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 portal, please send email describing the issue to for resolution. For more information about IBM's Ideas program visit

Add function to MQ to listen to ENF71 signal from TAMZ product(Broadcom)

We are using TAMZ product to elevate our ID's to gain higher access during a production issue or during the normal QMGR build process. The process of elevation is as below

1.Elevate our normal TSO ID to the EPV group ID which has access to DEFINE/ALTER MQ objects and this elevation is done by TAMZ product

2.Once elevation is complete, MQ admins will perform the task for DEFINE and ALTER etc.

The issue is as below


If MQ admin does not elevate his/her ID and tries to DEFINE/ALTER MQ object,MQ throws an error that he is not authorized to perform that action.This is perfectly fine.The issue is this error is cached for a very long period of time(months) and hence keeps giving the error until we issue RVERFIY SECURITY(user id) command against that MQ qmgr.

This is because MQ is not listening to ENF71 signal from TAMZ.

Please find below the link to Broadcom’s documentation that gives a bit of history of ENF71 usage by IBM and RACF/ACF2. It also points to CICS and DB2 explicitly as listeners for these events.

We understand from IBM case-TS008006688 that MQ does not have this function (to listen to ENF71 signal from TAMZ) currently and as per IBM recommendation from the above case as well as call with IBM advocates(, we are raising this RFE to add the function to MQ.

    We agree that this is a good idea. It is on the list for consideration in a future version of MQ.
