Upvote ideas that matter most to you
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.
Reorg blocking applications when using "allow write access"
While an "allow write acces" online reorg is running lock-wait contention can happen based on the number of rows being updated by an application. The locks for the application can escalate to lock an x lock. If this situation happens, the reorg sh...
Introduce a new parameter to the export utility to be able to export data from a table that is in a backup image.This functionality is especially useful for data extraction without touching/impacting the source system
Use package collection other than NULLID for CLP and Db2 Utilities
Db2/zOS colleagues want to get rid of lock issues with rebind of packages in schema NULLID, thus the decided to have Db2/zOS release specific package collections to provide actual and rebound packages for every Db2 release to the distributed (Db2/...

Allow a WHERE clause for ADMIN_MOVE_TABLE to delete data while moving a table
One of the most painful things to do is to delete a huge amount of data. One workaround for this is to export the data needed and then LOAD/REPLACE back into the same table, but this requires an outage of the table to accomplish. If a WHERE clause...
Many customers want to REORG their tables quickly and efficiently. The classic REORG is by far the fastest option but puts the table in read only mode. Inplace reorg allows write access but is much slower and not suitable for tables that have a hi...
For example, the customer wants to get the name list for tables which are in load pending status, he may issue a SQL statement "select tabschema,tabname from sysibmadm.admintabinfo where load_status='PENDING'", the statement will execute for a ver...

overrule the automatic CPU parallelism calculation of LOAD apart from command line
LOAD does an automatic CPU parallelism calculation, if not explicitly specified in the command by the user.To gain max performance, LOAD assumes, it is the only LOAD (and only application) running on the system and consumes nearly all available CP...
