This three-day course examines the fundamental mechanics of IBM's parallel sysplex architecture at a detailed 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.<br>This vital course should be considered the technical 'foundation stone' for all involved with a sysplex at a technical level.<br><br>This course is available 'on demand' (minimum 2 students) for public presentation and for one-company, on-site presentations.

Attendance of the course Parallel Sysplex Concepts & Facilities, or equivalent experience.

  • describe the Cross-systems Coupling Facility

  • explain the principles of data sharing
  • explain how connection services work
  • explain how data sharing works
  • explain how cache, lock & list services work
  • describe Workload Manager services.

Introduction to the Parallel Sysplex

What is a parallel sysplex?; XCF, the Cross-systems Coupling Facility; Multisystem environments; It's not just signalling!; But what about data sharing?; The Coupling Facility; Coupling Facility data - Structures; Data sharing services; OK, so WHY parallel sysplex?; How big!?!; A single image environment; A sysplex is just a bigger multiprocessor!; Dispatching work; Recovery and expendability; Continuous availability; Why the fuss about continuous availability?

XCF Services

Managing the sysplex; member status and attributes; joining a group; interrogating XCF; sending and receiving messages; advanced message services; large messages; User Status tracking; Group Status tracking; leaving a group; Abend handling; ARM concepts, policies and exit routines; Sample Application; JESXCF; JESXCF services.

Data Sharing

CF data sharing; Coupling Facility data structures; CF sharing mechanics; products supporting data sharing; XES services; application protocols.

Connection Services

connection services overview; permissions to use a structure; allocation of structures; first connection; allocation parms; connection failures; LISTEN exit; Connection States; connection & structure persistence; structure rebuilds; Structure Alter and Disposition; disconnecting from a structure; CF management services.

Cache Services

Elements of a cache system; elements of a cache structure; allocation parameters; event suppression; managing the local cache buffers; Local Cache Vector; casting out data; cast-out Classes, Storage Classes, Reclaims and Reclaim Vectors; Cache Types; synchronous and asynchronous services; physical CF access processing; changed CF requests.

Lock Services
