Book description

The beginning of the new century sees the data center with a mix of work, hardware, and operating systems previously undreamed of. Today’s challenge is to manage disparate systems with minimal effort and maximum reliability. People experienced in scheduling traditional host-based batch work must now manage distributed systems, and those working in the distributed environment must take responsibility for work running on the corporate OS/390 system.

This IBM Redbooks publication considers how best to provide end-to-end scheduling using IBM Tivoli Workload Scheduler Version 8.2, both distributed (previously known as Maestro) and mainframe (previously known as OPC) components.

In this book, we provide the information for installing the necessary Tivoli Workload Scheduler 8.2 software components and configuring them to communicate with each other. In addition to technical information, we consider various scenarios that may be encountered in the enterprise and suggest practical solutions. We describe how to manage work and dependencies across both environments using a single point of control.

We believe that this book will be a valuable reference for IT specialists who implement end-to-end scheduling with Tivoli Workload Scheduler 8.2.
