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.
Simple way to check consistency between DB2 and IDAA
When implementing data replication we found a number of tables showing different number of rows in DB2 and on IDAA (2 IDAAs installed with replication). To verify this we did as follows:- Disable table for acceleration in IDAA1- Run SPUFI with SEL...
Need a way (automated) to cancel very long running SQLon the Netezza Appliance(IDAA) that is impacting the CDC data latency running on Z/OS LPAR. Some type of governor is needed in the Netezza Appliance in order to insure that no run away SQL runn...
If customers need FAILBACK capability back to Db2 in case SQL has an issue in accelerator, they currently use ENABLE WITH FAILBACK option. However, the routing criteria of ENABLE option includes cost factors calculated by optimizer. Customers want...
Monitor IDAA for z/OS physical filesystem in size in real time
There are different UIs such as Data Studio, DSM and and Admin UI and they provide different metrics for storage usage in IDAA on Z. Such as; - Table size in data studio determined at the table level, - Used Space in data studio which comes fro...
Since timestamps with timezone specification is not supported into the current last version of IBM DB2 Analytics Accelerator for zOS 7.1, even if the same functionality is already implemented into DB2 for zOS, SIA asks it will be implemented the s...
