How to use WRKSYSSTS to monitor your system -- Part I
A well-tuned machine pool is essential for good performance. Use the Work with System Status (WRKSYSSTS) command to monitor and maintain it, as well as other pools on the iSeries.
How to use WRKSYSSTS to monitor your system -- Part II
There are two "meters" of performance on the Work with System Status (WRKSYSSTS) display: page fault rates and job transition rates. Making sure those fall within acceptable levels is the essence of using the WRKSYSSTS display to tune your system.
Using WRKSYSSTS to tune your system
Once you understand how to assess performance, basic tuning of your system is relatively straightforward. There are two ways to tune your system on the WRKSYSSTS display. You can adjust pool size to reduce page faults, or you can adjust activity levels to minimize wait-to-ineligible and active-to-ineligible transitions. Using those methods, follow these five tuning steps to bring your system in line.
