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.

Populate DSSIZE for ALL pagesets to simplify monitoring and avoiding pageset full conditions

new accounting trace field to indicate if distributed connection was secure or not
We have recently enabled the SECPORT in all our Db2 subsystem. And now it is possible for a distributed client to use the SECPORT (instead of TCPPORT) and establish a secure SSL/TLS connection to the Db2. Great. Ideally, I would like to shut down ...

in Db2 for z/OS
Functionality already exists
With early versions of DB2 the performance of EXPLAIN was not relevant. Nowadays, where DBAs do thousands of EXPLAINs, the performance and turnaround is getting critical. I think there is room for better performance and throughput of mass EXPLAINs...
DB2 Z/OS Sync Logical and Physical Parts after full Reorg
ADD PART was used to insert a new physical partition in the middle of a tablespace. Now the Logical and Physical partitions are mismatch. If a Full Reorg on the full tablespace is performed, the utility can include an option to resync the logical ...

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 ...
