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.
Il n'y a pas de sessions publiques à ce moment. Nous organisons volontiers un cours en entreprise ou une session publique supplémentaire (en cas d'un nombre suffisant de participants). Intéressé? Veuillez contacter ABIS.
The course is appropriate for all those whose work brings them into contact with parallel sysplex, including managers, systems programmers, operations personnel and all support staff.
Familiarity with the current z/OS structure, initialisation and operation.
