(A high-activity user is someone who presses the Enter key all day long, such as an order-entry employee.) Such users alone can be responsible for a majority of the transactions that your system processes each day. Making sure these employees never have to wait on the CPU is key to making them efficient. We also learned about private storage pools and shared storage pools and how to route users to the storage pool you want. Now, let's take a look at how to set the two parameters that govern the performance of jobs in a storage pool, activity levels and pool size. In particular, we will determine these two numbers for the example private storage pool for our order-entry personnel. >>View Complete Tip SPONSORED BY: Bytware, Inc.

Now, lets look at some specialized tuning techniques that can make the difference when trying to get your system to fall within standard performance levels. How to track response time with the WRKACTJOB tool To obtain maximum productivity from computer users, it is essential to limit the computer's interactive response time to one second or less. Using the Work with Active Jobs (WRKACTJOB) screen you can see detailed performance data for each job listed. 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. 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.  Announcements & Links   EXPERT PROFILE Rich Belles, systems management expert Richard's data processing career has spanned more than 30 years.
