Maximizing WebSphere Performance on z/OS Training Course and Workshop in Bangalore, Mysore, Chennai, Hyderabad, Pune, Mumbai, Delhi, Noida, Gurgaon, Kolkata

In Maximizing WebSphere Performance on z/OS training course, learn how to analyze the WebSphere Application Server (WAS) for z/OS performance. Develop skills to tune WebSphere for z/OS and its environment to reach maximum performance. Benchmark tools are used to simulate a Java Enterprise Edition (J2EE) transaction workload against WebSphere for z/OS, and then performance tools are used to monitor performance data on these transactions.

By attending Maximizing WebSphere Performance on z/OS workshop, delegates will learn to:

Simulate workload in a WebSphere for z/OS environment; install and use tools for performance measurement
Establish a methodology for making performance measurement runs
Investigate the current hardware resources and understand how to minimize the WebSphere for z/OS storage demand
Explain the importance of WLM for WebSphere for z/OS performance
Describe the resource areas for monitoring
Use SMF and RMF for tuning decisions
Investigate HTTP and WebSphere for z/OS performance
Describe the default UNIX thresholds that can be changed
Tune the Hierarchical File System (HFS) and Language Environment (LE) environment
Trace performance problems to check WLM applications
List tools available to monitor the application running in the JVM
Use IBM Tivoli Performance Viewer to monitor real-time performance of WebSphere for z/OS J2EE applications
Understand the SMF records created by HTTP server and the HTTP protocol
Explain the different ways to configure the connection between the WebSphere for z/OS plug-in and a J2EE server instance when using the HTTP protocol
Tune the HTTP session management function to use distributed session management
Understand and implement WebSphere for z/OS Internal Replication services
Describe the Java technology in z/OS
Plan for the utilization of zAAP processors to reduce the cost of running WebSphere for z/OS workloads
Quantify the possible utilization of zAAP processors by a specific installation's WebSphere for z/OS workload
Understand how garbage collection works and the Persistence Reusable JVM
Tune the JVM
Apply tuning to the WebSphere for z/OS runtime environment and understand the different behavior of runtime-dependent settings
Use dynamic cache services to improve performance for Web applications
Understand how parallel sysplex and WebSphere for z/OS clusters provides scalability and availability; cloning and data sharing for WebSphere for z/OS

WebSphere Application Server for z/OS Implementation Experience
Basic knowledge of system measurements and analysis of performance data provided by z/OS functions, such as System Measurement Facility (SMF), Resource Measurement Facility (RMF) and TCP/IP

This Maximizing WebSphere Performance on z/OS class is meant for experienced z/OS and system programmers, who implement and customize the WAS on z/OS, and Information Technology (IT) professionals, who deploy Enterprise JavaBeans (EJB) and Web applications on z/OS.
