WebSphere Application Server for z/OS Performance Tuning

IBM Course Code: ZU715G

GK# 720421 Vendor# ZU715G

Course Overview

TOP

This course teaches you how to discover components that might cause a performance problem in the WebSphere infrastructure.

WebSphere Application Server for z/OS provides a Java2 Enterprise Edition (J2EE) runtime environment for Enterprise JavaBeans (EJB), along with servlets and JavaServer Pages (JSP) in web applications.

The course begins by showing you how to log on to z/OS, find the WebSphere components, and determine the current system status. The course then describes where WebSphere should fit among its dependent products such as DB2, IMS, and CICS, and introduces you to memory and subsystem considerations.

After familiarizing you with the overall environment, the course presents a series of tuning demonstrations on the sample z/OS infrastructure. The demonstrations cover topics such as z/OS workload management, adding goals and report capability to the WebSphere cell, and gathering data about the cell by using resource monitoring. You then learn how to use the collected data to determine processor usage per transaction within the WebSphere cell.

Finally, you learn how to install and use the IBM Support Assistant and the svcdump.jar tool. You see how to use the IBM Support Assistant to gather and analyze garbage collection data, and create a service dump of the WebSphere address spaces with svcdump.jar. You then learn how to use svcdump.jar to print the threads from the dump and examine what was happening at the instant the dump was taken.
