Objectives
On successful completion of this course, attendees will
be able to:
- adjust working practices to the new Sysplex environment
- minimise potential Sysplex problems
- resolve Sysplex problems efficiently.
Who Should Attend
Systems programmers, operations and support staff who need to operate, and recognise and respond to problems occurring in, the parallel sysplex environment.
Prerequisites
Familiarity with z/OS commands and a good understanding of the principles and concepts of parallel sysplex, including XCF commands. This can be gained by attending RSM's course Parallel Sysplex Concepts & Facilities.
Duration
2 days

Sysplex Operations
Setting the Sysplex timer; Sysplex parameters and the IPL process in a Sysplex; IPLing to initialize the Sysplex; I PLing into a running Sysplex; removing a system from the Sysplex; shutting down the Sysplex; re-initialising the Sysplex; managing and reconfiguring the Sysplex environment; path reconfiguration; switching couple datasets (why and how); switching CFRM policies; removing and re-instating a coupling facility; displaying CF resources; the WLM and Logger environments; rebuilding and reallocating structures in the CF; System-Managed Duplexing of structures.
IPL Problem Determination
An introduction to the underlying cause of most IPL problems in the syplex and the real options available to deal with them, followed by some actual examples.
Runtime Problem Determination
An overview of the major types of problem and how to avoid them, then how to recognize and deal with each in turn; signalling connectivity failures; System Status Update Missing conditions; using the Sysplex Failure Manager; SFM Policies and options; SFM’s other effects; managing the SFM environment; Sysplex Timer problems and how to deal with them; Couple Dataset problems; CF environment failures; ARM, its policies and defaults; operating within an ARM-enabled environment.
