New Tivoli Solutions Deliver Seamless

e-business Management for IBM S/390 Servers

(Planet Tivoli) - Tivoli Systems, Inc. today announced the appointment of industry luminary Bob Yellin, former chief technology officer and senior vice president of Legent Corporation, as general manager and vice president of Tivoli's S/390 Division. Under Yellin's leadership, Tivoli will continue its strategy of increased investment and focus on S/390 management to provide the rapidly growing base of OS/390 customers with the most comprehensive, cross-platform, e-business management solution in the industry. Capacity demands of new workload applications such as e-business and ERP are fueling OS/390 usage, accounting for 25 percent of S/390 capacity shipment growth last year. More than ever, customers need integrated IT Process Automation and end-to-end management of these new networked environments that span from the mainframe to the desktop and out across the internet.

With more than twenty years experience spearheading development, strategic planning and technical management initiatives including BST Software's ENDEVOR and Legent Corporation's overall product and technical strategies, Yellin will play a key role in driving Tivoli's double digit growth in OS/390 enterprise management.

Tivoli today made a related announcement demonstrating the company's lead in the management of heterogeneous IT environments. (See related Tivoli press release issued today, "Tivoli Delivers New e-business Management Solutions for OS/390 Environments"). The new Tivoli management products provide customers with integrated service level management, the ability to manage all host and distributed environments from OS/390 and extended network management support while providing business process views of all enterprise applications.

"The need for server power is growing exponentially due to the enterprise-class capacity demands of e-business applications," noted Rick Sturm, president of independent analyst firm, Enterprise Management Associates. "With new products developed under a single architecture to span both host and distributed environments and access to IBM sales, and IBM research and development, Tivoli is delivering to customers a solution that addresses the cross-platform management challenge. With these advancements, I expect Tivoli will further its leading position in enterprise management."

"In the world of e-business, companies can face the difficult task of managing massive transaction volumes across applications, systems, servers and networks," said David R.Carlucci, general manager IBM S/390 Division. "Combining Tivoli Enterprise management solutions with the advanced transaction capabilities of S/390 gives enterprise customers the industry's leading solution for managing complex heterogeneous environments."

Tivoli management of IBM environments is being made easier for customers since all IBM hardware and software products are being integrated and certified "Tivoli Ready." These Tivoli enabled products -- from IBM ThinkPads, NetFinity servers, RS/6000, AS/400 and S/390 hardware, to e-business applications and middleware such as IBM's MQSeries, CICS, DB2 and Lotus Domino -- will allow customers to automatically discover, inventory and manage the environments with Tivoli enterprise.

Eliminating Islands of Management

With nearly 70 percent of all corporate data in the world residing on S/390 servers, continuous management of these systems is crucial. Previously IT organizations had to manage using different tools that resulted in islands of management between host and distributed environments. As a growing number of companies rely on the S/390 server's industry-leading capacity to power distributed enterprise networks, Web server environments, e-business and ERP applications, the need for seamless end-to-end management becomes crucial to providing consistent quality and availability. The new Tivoli solutions give customers the ability to centrally manage and analyze business system functions from their platform of choice while helping to preserve existing investments in S/390 management solutions.

"In the new networked economy of e-business, the 'customer experience' is essential," said Martin Neath, executive vice president, Tivoli Systems Inc. "If your enterprise systems are not functioning, your customers may move to the competition that is only a mouse click away. Under Bob Yellin's direction, Tivoli will further its efforts to ensure that all aspects of the enterprise, especially OS/390 connected and driven applications, systems, storage and networks, are managed in a unified fashion."
