Preface

IBM® Tivoli® Workload Scheduler and IBM Tivoli Dynamic Workload Broker are
key products in the comprehensive, on demand IBM Tivoli Workload Automation
portfolio. Tivoli Workload Scheduler is the IBM centralized job scheduler for
distributed, mainframe, and end-to-end environments that allows you to do batch
scheduling based on a calendar. Tivoli Dynamic Workload Broker extends Tivoli
Workload Automation capabilities by providing dynamic optimization of workload
processing based on the performance of the scheduling infrastructure and
workload demands.

In this easy-to-follow IBM Redbooks® publication, we cover different scheduling
scenarios with Tivoli Workload Scheduler V8.4 and Tivoli Dynamic Workload
Broker V1.2 in distributed environments. We also discuss best practices for
designing and implementing a scheduling solution for small, medium, and
enterprise accounts.

Finally, we cover the sales engagement planning for a Tivoli Workload
Automation portfolio, including a sample statement of work. The primary
audience for this section is Business Partners and pre-sales Systems Engineers
working in this area.

This book is a major reference for IT Specialists and IT Architects working in the
Tivoli Workload Automation area.

Chapter 1. Workload scheduling
overview
IBM Tivoli Workload Scheduler and IBM Tivoli Dynamic Workload Broker are two
key components in the comprehensive IBM workload automation portfolio.
Before discussing these products specifically, and how to use them together in a
combined solution, we thought it is best to give an overview of workload
scheduling in general and the products that comprise the IBM workload
automation family.

In this chapter, we cover the following topics:
“Market trends and directions” on page 4
“Business solutions” on page 5
“Tivoli Workload Automation in action” on page 7

1.1 Market trends and directions
The number of organizations replacing manual, time-consuming workload tasks
with automated capabilities continues to increase at a rapid pace. This is done
with good reason. When performed manually, these tasks can quickly overwhelm
IT staff, increase overall costs, and have a negative effect on service level
agreements (SLA).

The adoption of Grid computing for business applications is expanding in various
sectors, such as insurance, manufacturing, and financial industries. The Grid
computing environment is a complex environment for business solutions that
requires workload automation, job scheduling, and processing. It is complex to
address the need for a central point of control to prioritize, manage, and integrate
workloads with data for enterprise jobs. In addition to this complexity is the
requirement to match computing resources to workload requests in a dynamic
fashion without human intervention. Accuracy, efficiency, and flexibility are
difficult to maintain.

The market is evolving into a virtual computing environment where clustering,
scheduling, and managing workload automation are needed within this virtual
environment. Service execution becomes important for delivering operational
services to the IT infrastructure and the enterprise. Traditional management tools
such as a job scheduler, load balancer, and cluster manager can automate some
of these activities. However, these tools leave IT organizations without the ability
to automate, dynamically manage, or optimize service execution activities
end-to-end across the enterprise.

While the service execution process is straightforward, it is exceptionally difficult
to manage. Management tools must be able to support business processes,
enable planned changes to business processes and the IT infrastructure, adapt
to unplanned changes in the IT infrastructure, maximize workload velocity,
optimize the utilization of IT resources, adhere to stringent SLAs, and ensure
compliance. Additional difficulties arise from trying to manage complex,
heterogeneous applications and systems as well as processes across
organizational silos. Finally, IT organizations that are already limited in resources
must somehow deal with a growing number of mixed, interdependent, and often
unpredictable workloads that need to be scheduled in real-time, near-real-time,
or batch modes.

Enterprises are embracing the service-oriented architecture (SOA) common
programming methodology to provide business applications across
heterogeneous platforms, operating systems, and data sources. There is the
need to provide a batch-on-grid solution to improve business efficiency, utilize
resources, reduce costs, and achieve service level agreements for job execution.
