Work Management Magic – Calm the Chaos with Subsystems

As shipped by IBM, the default configurations of IBM i work well.  However, as the complexity of environments grow, the stock settings can make it difficult to fully understand and manage the workload.

IBM provides the ability to customize and tune the system, and in particular, use subsystems to better manage remote database access.  Many shops fail to embrace these work management capabilities. 

This FOCUS session will cover the benefits of using subsystems to their fullest extent to organize and optimize applications on your system. This session will guide you through the work management features that can be used to help you fully understand system resources used by your applications and tune them for best performance.

We will concentrate on how to set up subsystem descriptions and their various components, how to tune prestart job entires, how to tune memory pools used by subsystems, best practices for job descriptions, how and when to leverage workload groups, and more. 

This session will focus on using Navigator for i to do these tasks.  It will also touch upon how the Performance Data Investigator can help with your tuning exercises.

This session is intended for those who do not have extensive experience in setting up custom subsystems, routing work to those subsystems, and managing the performance of your IBM i. However, even for those who have embraced the use of custom subsystems for their environments, the session will have some tips for everyone.
