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.

Set DB2 ZPARMs TSQTY and IXQTY to -1

Please would it be possible to set the DB2 for z/OS ZPARMs, TSQTY and IXQTY, to -1? Virtually all of our tablespaces and indexspaces are created with a PRIQTY and SECQTY of -1. It would be really useful to set the default values for TSQTY and IXQTY to -1 in the ZPARMs to allow our tablespaces and indexspaces to be created without PRIQTY/SECQTY parameters. Simplify tablespace and indexspace creation and allow DB2 to manage the space.

    Hello Neil,

    The documentation changes to clarify that -1 is the default for the PRIQTY and SECQTY options of CREATE INDEX and CREATE TABLESAPCE are now published. See:

    Hello Neil,

    Thank you for submitting this Aha! Idea. Our development team has reviewed it and indicated you can set TSQTY and IXQTY to 0, which should have the same effect as what you are asking for, to Create Tablespace and Create Index without specifying PRIQTY and SECQTY, and set zparm TSQTY and IXQTY to 0.

    It should have the same effect as PRIQTY -1 and SECQTY -1.

    We are also updating the syntax diagram in our IBM documentation to support the above.

    Please let us know if you have any additional questions or comments.
