z/OS can handle unpredictable workloads and allows high CPU and I/O utilization while still meeting response goals with minimal human intervention for setup and operation.
Workload management and automation on z/OS has achieved a very high degree of automation and can utilize otherwise lost system resources in a mixed workload environment.
z/OS supports installation set policies to ensure that each different workload obtains the resources appropriate to its priority. Management for z/OS is highly automated, including the scheduling of workloads, resource allocations, and responding to potential and major errors.
z/OS has a lead in the industry because of its ability to get the job done, on-time, day after day, year after year, decade after decade. No other system can match the S/390 track record. At the same time z/OS has evolved with a compatible architecture for over 30 years.
Previous application investments have always been protected. And they always will be, even while zSeries grows to keep pace with customer needs. z/OS starts a major ease-of-manageability initiative with the introduction of Managed System Infrastructure for Setup (msys for Setup) as a new base element. msys for Setup offers a new approach for installing and configuring z/OS components and products, resulting in significant productivity improvements.
z/OS Resource Measurement Facility (RMF) is the window on z/OS resource usage. Information is gathered at the Parallel Sysplex environment, single system or address-space level and reports are available at any system in a Parallel Sysplex environment. Real time performance monitoring is handled by Performance Monitor (PM).
The unique and rich functions of System Automation for z/OS (SA z/OS) Version 3.2 can ease z/OS management, reduce costs, and increase application availability. SA z/OS automates I/O, processor, and system operations and includes "canned" automation for IMS, CICS, Tivoli OPC, and DB2. Its focus is on Parallel Sysplex automation, including multi- and single-system configurations, and on integration with end-to-end Tivoli enterprise solutions.
