IBM Tivoli OMEGAMON XE V3.1 Deep Dive on z/OS

2 IBM Tivoli OMEGAMON XE V3.1 – Deep Dive on z/OS

1.1 Performance management

The IT infrastructure of your enterprise supports many important business

operations. Therefore, ensuring IT infrastructure reliability and availability is

critical for business success. Given the increased complexity of IT infrastructures

in general and e-business infrastructures in particular, intelligent, robust

performance and availability management tools are essential for the proactive

identification and resolution of problems before they affect business operations.

You need tools that enable you to effectively monitor individual resource

performance as well as overall business processes, while gauging resource

functions and availability across your heterogenous IT infrastructure.

Back-end systems with a mainframe running z/OS have been the life-blood of

many organizations, and although these mainframes have been designed to be

robust and reliable, they still require management to ensure optimum

performance, high availability, and superb reliability. Key performance

management concerns regarding z/OS include:

򐂰 Ability to effectively manage a large number of systems and partitions with a

limited number of operators.

򐂰 Early warning system to detect potential performance problems and perform

corrective efforts, even before an outage happens.

򐂰 Common and uniform mechanism for performance management to limit

switching systems and easier knowledge transfer for operators.

򐂰 Assistance in getting all of the lean power of the mainframe performance to

ensure that all the overhead that occurs is essential.
