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.

Workspace Db2 for z/OS
Created by Guest
Created on Sep 22, 2021

Client Application Name (QMDAAPPL from IFCID 0003) used in column RLFEUAN from SYSIBM.DSNRLMTxx tables to governor distributed applications

We would like to use table SYSIBM.DSNRLMTxx (SYSIBM.DSNRLMT01) in order to avoid that certain applications, coming from distributed environment and reaching Db2 for z/OS through DDF, can execute SQL statements.

We’d like to completely block these applications specifying ASUTIME, RLFASUERR and RLFASUWARM equal 0.

We know that this application runs in distributed platform in a file called ‘Pesquisa db2.exe’ (this is just an example).

We also know, through case TS006740623, that the field used in SYSIBM.DSNRLMTxx to specify application name is RLFEUAN and the value in RLFEUAN should be the exact name which appears on an Accounting Trace in Field QWHCEUTX/TRANSACT (obtained from the one which appear on internal Control Block CCB).

But we noticed that the value of QWHCEUTX/TRANSACT for application “Pesquisa db2.exe” is truncated on the first blank and appears like “Pesquisa”.

But If I specify only “Pesquisa” in RLFEUAN, I will block another applications whose name starts by “Pesquisa”, e.g “Pesquisa teste.exe”, that in fact I don’t want to block.

I’d like to be precise about application name I’m informing in RLFEUAN to block exactly what I want to block.

We noticed that in Accounting Trace field called 'CLIENT APPLNAME’ (QMDAAPPL) we have the complete name of application coming from distributed environment: “Pesquisa DB2.exe”.

I’d like that I could specify this complete name in RLFEUAN (the same that I see in QMDAAPPL) in order to be more granular in terms of identifying application I want to limit resource consumption.
