Pool Advisor for Db2 is available as a stand-alone product or is entitled as part of the MainView for Db2 Management Solution and has some impressive capabilities around storage management, pool management, and advisors to help tune and maintain resource usage within acceptable levels.


Pool Advisor for Db2 provides the ability to balance the needs of the system and the needs of Db2 to optimize memory usage for the best performance of your database environment.  This powerful solution provides:


  • Expert assistance in the form of a buffer pool, EDM pool, dynamic caching, sort pool, RID pools, and group buffer pool use. 
  • Recommendations about storage resource allocations, object configuration, and some Db2 parameter settings. 
  • Real-time management of some of these resources to improve performance and throughput, automatically if permitted


The Advisors will cause an alert in Pool Advisor complete with recommendations on how to fix the problems.  Recommended actions can be taken from pool advisor through the Command Interface or in the Db2 environment for recommendations such as changes to zParms. There is also a Configuration Advisor that will analyze the performance data and produce the JCL necessary to change the configuration for optimal performance helping to guarantee the best configuration across multiple workloads.


This introduction helps set the stage for the importance of the latest updates to Pool Advisor for Db2.


In December of 2019 there was an enhancement that added reporting capability for data sharing groups across all the different supported pool types.  More information about this enhancement can be found here.


The latest update available on July 16, 2020 will allow the messages associated with an Alert to be written to the console.  This way when there is a performance problem automation can be used to notify the correct individuals and possibly open tickets about the issue.  This is important to make sure resource shortages or other related issues can be fixed much faster even when someone is not looking at the screen.


For more information on how to get this enhancement please see the Technical Bulletin located here.
