Course Overview
The IBM Parallel Sysplex Implementation Workshop (ES42G) is an intermediate-level, instructor-led course designed for system programmers, subsystem programmers, and IT professionals responsible for implementing hardware and software in a Parallel Sysplex environment. Developed by IBM, this 36-hour training program provides comprehensive coverage of z/OS and related subsystems that leverage Parallel Sysplex components, with a strong focus on resource sharing and high availability. While it does not directly align with a single certification exam, successful completion contributes to mastery in IBM System z environments and supports pathways toward IBM Professional Certification. According to IBM, enterprises running mission-critical workloads on z/OS increasingly adopt Parallel Sysplex for continuous availability, with over 90% of Fortune 500 companies using z/OS-based infrastructures relying on sysplex configurations for scalable, resilient operations.
Participants engage in extensive hands-on labs delivered through instructor-led online sessions, using real-world scenarios to build, configure, and migrate sysplex environments. The course covers critical technologies including z/OS, Hardware Management Console (HMC), Coupling Facility (CF) architecture, PARMLIB settings, and HCD (Hardware Configuration Definition) coding. Students progress through a structured lab sequence: starting by building two stand-alone z/OS systems, then creating a two-system base sysplex, dynamically migrating to a Parallel Sysplex, adding a third coupling facility, and implementing key CF exploiters such as Coupling Facility Data Tables and Global Resource Serialization. These labs simulate enterprise-scale deployment challenges, allowing learners to practice recovery scenarios and ensure system resilience under failure conditions—all within a remote-access virtual lab environment that mirrors production mainframe infrastructures.
By completing the IBM Parallel Sysplex Implementation Workshop (ES42G), professionals gain skills directly applicable to maintaining highly available, scalable mainframe environments, preparing them for roles such as Mainframe Systems Programmer or z/OS Infrastructure Specialist. Certified individuals report average salary increases of 15–20%, with senior z/OS specialists earning upwards of $130,000 annually in North America. Koenig Solutions offers this official IBM course with a Guaranteed-to-Run schedule, 1-on-1 training options, and access to authorized IBM courseware, ensuring learners receive expert instruction and hands-on experience. Graduates are well-positioned to lead Parallel Sysplex implementations, optimize system performance, and support digital transformation in enterprise IT environments.
