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.

Add debugging/information options for encrypted client connections

While configuring/troubleshooting a Db2 LUW server in a setup with encrypted connections, we need methods to identify the encryption status and ciphers used.

E.g. Db2 client is connecting to a Db2 LUW server: I have no means to verify, which TLS cipher was negotiated and if TLS11 or SSL or TLS12 was used.

In MON_GET_CONNECTIONS I just get SSL4 in the column CLIENT_PROTOCOL but I cannot see what level/port was used.

We could need a db2diag.log or notification log entry for the connection type and cipher negotiated.

If I use the simpler AUTHENTICATION=SERVER_ENCRYPT, I cannot see, which connection complies or which is using ALTERNATE_AUTH_ENC.

The same issue appears with Db2 Connect servers to host connections. I can only see on Db2 for z/OS, if the Db2 LUW server is using a secured connection.

At least, if Db2 is all delegating to GSKit, there should be a documented way, how to retrieve this information via GSKit.
