Advanced Performance Management: WLM, Sysplex, and USS
Mainframe Training Overview
The course will concentrate on the taking an integrated approach to performance management by addressing the z/OS e-business perspective. Elements to be explored will focus on Workload Manager functions, the parallel sysplex, and UNIX system services and how each can be monitored and managed for optimum performance
Course is designed for performance analysts or systems programmers that have a need for a better understanding about the mechanisms and data available for performance management in the e-business environment.
Basic understanding of the z/OS Operating System, WLM, and UNIX system services.
