Use profile tables for local applications

We use profile tables successfully for different scenarios. In addition to remote applications, our DB2 IT infrastructure also includes local applications for which we also have profile table usage scenarios. For example, we set the explain mode f...

Allow reset of all High Water Mark Statistics values

Currently some statistics HWM values are not reset while Db2 is active - e.g. Q3STCTHW. Consequently a transient event can hide a long term situation. This idea would allow those statistics to be re-set to zero - allowing performance management to...

New Db2 ZPARM for specifying SMS storage & management classes for FlashCopy image copies

When doing FlashCopy image copies the Db2 utilities create image copies by ADRDSSU and it passes the same SMS storage & management classes as the Db2 spaces.This is not always wanted as the performance and management requirements are in most c...

proactive messages of objects ??% full or 'follow-up objects free space' function inside Db2

Follow up TS and XS limits in Db2 z/OS is not an easy job. The last 6 months, we coped issues with partitioned indexes full. This were partitioned bases 'temporarily session' tables for applications, whereby the not active partition is cleaned up ...

Improve performance of EXPLAIN

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...

issue DISPLAY BLOCKERS instead of DISPLAY CLAIMERS when DRAIN timeout
