BMC Mainframe: Parallel Sysplex Internals & Fundamentals

The course is developed and delivered by © RSM Technology.

This three-day course examines the fundamental mechanics of IBM's parallel sysplex architecture at a detailed technical level. It will provide attendees with a full and comprehensive understanding of today's sysplex, an environment that can provide continuous availability for a huge variety of workloads. The course describes in considerable detail the three sets of services involved.

This vital course should be considered the technical 'foundation stone' for all involved with a sysplex at a technical level.
