IBM TWS Solution Overview

4 Workload Scheduling • The Challenge: Meet Increased Demand, Maintain Dependability, and Control Costs • The Solution: IBM Tivoli Workload Scheduler • The Results: Cost Avoidance, Improved Productivity and Greater Stability Implement IT Business Processes ‣ The planned part of event management ‣ The nucleus of the data center ‣ Core to the business

5 IBM Tivoli Workload Scheduler Job Scheduling Console Distributed Engine z/OS Engine Distributed Agent z/OS Agent Application Extensions Integrated End-to-End Scheduling • Control cross-platform scheduling from a single plan and a single console On z. Series • Complete mainframe-based solution including catalog management For Distributed Systems • Complete network and node level fault tolerance • High performance and scalability

6 IBM Tivoli Workload Scheduler High performance, scalability, availability True end-to-end job scheduling § Fully fault tolerant: No loss of work due to system or network outage § Highly flexible: Schedule hundreds of applications through our interfaces or our open APIs § Highly scalable: Thousands of end points with no sacrifice in performance or function § High performance: Millions of jobs! § § § Multi-tier architecture allows greater scalability High fault tolerance for better stability Heterogeneous platform support for flexibility One true enterprise class scheduler Central planning for either host or distributed environments or both – all controlled from one user interface

7 IBM Tivoli Workload Scheduler Highlights Manages cross application workloads Enhances productivity Provides high level of availability § Integrate highly sophisticated scheduling features of IBM Tivoli Workload Scheduler to e-business application environments § Leverage the built in workload capabilities of Oracle e -Business Suite, People. Soft 8, SAP R/3, and other applications via powerful API. § Single administrative console § up-to-the-minute information on job status and statistics § Track job contingencies to improve capacity and increase performance § § Secure, fault tolerant workload management Rules-based processing for improved data integrity Automatic recovery and restart capability Provides an applications-level view to system monitoring tools

Database Objects Workstation Where the work is performed Calendar List of dates to run (or not run) a job stream Job Which script or command to run Job Stream Collection of Jobs to run, when to run them, and with what dependencies

Scheduling Object Database Jobs and Job Streams Workstations Calendars Resources Parameters • Master database resides only on Master Domain Manager (and optionally backup Master) • Database is proprietary, high performance ISAM – No database administration is required – Small footprint and low performance impact – Improves fault tolerance and scalability 12

IBM TWS for Applications technical insight Extending IBM TWS’s Capabilities

25 What is an Extended Agent? • An extended agent (x-agent) is a system or application that is dependent on its ITWS host to receive scheduling instructions • IBM TWS accepts information from the x-agent • The Interface between IBM TWS and an x-agent is called the access method • Extended Agents and Access Methods are fully documented in the “X-Agent Programmer’s Reference” • IBM-provided integration to SAP R/3 and Business Warehouse, People. Soft, and Oracle e-Business Suite is included in IBM Tivoli Workload Scheduler for Applications

26 Extend-agent Network FTA X-agent access method Your “outside the box” platform or application

28 Summary • Extended Agents provide an effective mechanism for extending IBM TWS’s scheduling capabilities to foreign platforms and applications • Extended Agents can also help segregate applications into workload groups (by CPU) • Extended Agents talk to a IBM TWS agent through what is called an access method • Access methods are fully documented and easy to write!
