BMC Mainframe: Parallel Sysplex Implementation, Customisation & Exploitation

The course is developed and delivered by © RSM Technology.

This in-depth, five-day course examines the issues involved in implementing the parallel sysplex environment. It covers hardware configuration issues, setting up the cloned z/OS environment, setting up the sysplex software environment, setting up sysplex data sharing, the system logger and the exploitation of z/OS components.

Extensive, real-world hands-on practical sessions occur throughout the course.
