Advanced z/OS Performance: WLM, Sysplex and UNIX Services Schulung

Einführung in WLM, Sysplex und UNIX Services
Advanced z/OS Performance: WLM, Sysplex and UNIX Services

Today z/OS supports new workloads running as e-business servers, including the IBM Hypertext Transfer Protocol (HTTP) Server and WebSphere. These workloads exploit the latest features of the z/OS runtime environments, including Parallel Sysplex, Workload Manager (WLM) and UNIX System Services (USS). New hardware technology such as zAAP and zIIP processors can be exploited for selected workloads, and the WLM Intelligent Resource director balances workloads across clustered LPARs in a sysplex.

Examine the performance management and monitoring components of the Parallel Sysplex, USS and WLM environment, using extensive Resource Management Facility (RMF) reports and console displays to understand what is happening in the system. Based on this foundation, analyze case studies involving the HTTP Server in detail. Finish with an introduction to performance and tuning with WebSphere V6 for z/OS.
