z/OS System Operations - Boot Camp


This comprehensive 'Boot Camp' course provides attendees with an accelerated learning approach to the operations role in a z/OS environment. The course is ideal for trainee and new operators who will be working in a z/OS environment.
The regular, hands-on lab exercises give students the opportunity to try out their newly-gained skills immediately. On successfully completing this boot camp, attendees will have reached the skill level needed to enable them to efficiently and effectively carry out the tasks required of an operator in a z/OS environment.

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