Parallel Sysplex concepts & facilities
This course is the essential technical introduction to Parallel Sysplex. The course describes and explains the components of the parallel sysplex concept and covers data sharing, installation, IPL, components & services and sysplex exploitation..
Students will acquire an understanding of:
- explain the reasons for the introduction of the parallel sysplex concept
- explain the business implications of the parallel sysplex
- describe the XCF function for connecting the systems
- explain how data sharing works
- describe the management of a sysplex
- explain how to exploit the benefits of the parallel sysplex.
