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.

db2look with -printdbcfg must support parameters with "automatic" value

To clone a database and all its objects IBM recommend to use the db2look utility. If you use the -printdbcfg to clone the db  configuration too the db2look utility generate the parameter values in the update commands but without the "automatic" value.


If you have the db heap parameter for example set like this


 (DBHEAP)             = AUTOMATIC(3370)


the db2look generates a command like "update db cfg for xxx using dbheap 3370" which leads to


 (DBHEAP)             = 3370


and that is not the same as above !


If you look for the db2look-syntax in the knowledge center you find the remark "For the parameters that support the AUTOMATIC value, you might need to add AUTOMATIC at the end of the generated UPDATE DB CFG command."


That is not practicable. After each clone process you have to manually compare the db cfg and replay the automatic flag.


db2look must clone the automatic flag too !
