IBM Power Ideas Portal

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 this portal to enhance a Power 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 and add comments to 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 Power teams 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.

RTVSYSVAL variable length requirements

IBM i, currently at V7R4M0.
Created CL program to retrieve the QSYSLIBL and QLURLIBL system values.
Compiled without errors.
When manually calling the CL program, the following error message was received.

Additional Message Information

Message ID . . . . . . : CPF1095 Severity . . . . . . . : 40
Message type . . . . . : Escape
Date sent . . . . . . : 10/25/21 Time sent . . . . . . : 13:22:24

Message . . . . : CL variable length not valid for system value QSYSLIBL.
Recovery . . . : See the IBM Knowledge Center,
http://www.ibm.com/support/knowledgecenter/ssw_ibm_i/welcome , for
information on the valid length of system values.

The same message occurs with the RTVSYSVAL SYSVAL(QUSRLIBL) command.

Using the link listed (http://www.ibm.com/support/knowledgecenter/ssw_ibm_i/welcome) I could not find anything indicate the correct CL variable length to use for either the System or User Library List system values. I found general information about retrieving system values in the CL Programming documentation, but not the variable lengths for these specific system values.

It is only by prompting the RTVYSYVAL command, placing the cursor on RTNVAR field, and then pressing the HELP key that a list of the variable type and length was found. It would be helpful if the error message could direct one to documentation showing the variable type length for the various system values. Or at least suggest using the help text.


Use Case:

Application programming (retrieving system values).


Idea priority Low

    The CEAC has reviewed this requirement and recommends that IBM view this as a “nice to have” LOW priority feature.

    Background: The COMMON Europe Advisory Council (CEAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CEAC has a crucial role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community and has therefore reviewed your RFE.

    To find out how CEAC help to shape the future of IBM i, see CEAC @ ibm.biz/BdYSYj and the article "The Five Hottest IBM i RFEs Of The Quarter" at ibm.biz/BdYSZT

    We typically don't put direct links to IBM Documentation in our messages, but FWIW, here is a direct link to the system value table that would have been helpful: https://www.ibm.com/docs/api/v1/content/ssw_ibm_i_74/rzakz/rzakzsysvaltable.htm
    We agree there is room for improvement in the CPF1095 message and will look into this further.
