This 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 datasharing, the system logger and the exploitation of z/OS components.
Extensive, real-world hands-on practical sessions occur throughout the course.
This course is available 'on demand' (minimum 2 students) for public presentations or for one-company, on-site presentations.
To gain maximum benefit from this course, students should first attend the course Parallel Sysplex Internals & Fundamentals, or already have a thorough understanding of the principles and mechanics of the parallel sysplex environment.
Delegates will learn how to
- identify the different stages of parallel sysplex implementation, and understand the benefits and implications of implementing each of these stages
- understand the hardware configuration for a parallel sysplex, including the Coupling Facility, CTC and sysplex timer environments
- set up a cloned, multi-system, shared SYSRES environment with appropriate SYS1.PARMLIB parameters (and a suitable backup SYSRES!)
- set up and maintain the controls for the parallel sysplex environment, including the Couple Data Sets, signalling environment, timer, GRS and parmlib member controls
- set up and maintain the CFRM environment
- set up and maintain an SFM environment
- interpret the various RMF reports associated with the sysplex environment
- set up and configure the following exploiters using the CF Sizer tool:
TCP/IP ports and DVIPA
