This course gives technical support personnel in a z/OS installation a clear understanding of the tasks involved in effective performance management. It covers conceptual performance issues as well as the significant technical considerations, such as parameters and I/O configurations.


The course also provides a comprehensive overview of the Workload Manager functions. All the key features are described during this course. The course will also include a number of practical online exercises.

As well as covering conceptual performance issues the course concentrates on the significant technical considerations of I/O tuning.


This course is available 'on demand' (minimum 2 students) for public presentations or for one-company, on-site presentations.


For corporate groups, we can organize this training as an on-site private group.
