Sysplex Failure Recovery Scenarios in 2024 Brought to Light by IBM zPET and WSC

Project and Program: Core Platform, z/OS Systems Programming

Tags: Proceedings , SHARE Kansas City 2024

Sysplex related failures occurs thankfully not so often. If you had one, you know what messages are coming, what to do , which actions needs to be taken. You also learn how to recovery fast or avoid them. If you never experienced any , it will be sometimes challenging to get ready for flow of actions that needs to be done, which parameters and settings are effecting your recovery senarious. What happens if a CF fails, sysplex workload spike happens such that CF capacity or resources are overwhelmed. If you have structure failure, what happens if you are using structure duplexing, asynchronous duplexing and if you are not using them any of them at all. IBM zPET STSM Keiron Hinds and WSC z/OS and parallel sysplex SME Meral Temel are working on some sysplex recovery senarious. They will showcase several sysplex failure senarious including accidental or disruptive failing action that takes CF LPAR or CPC down hard, Couple dataset configuration related issues. Senairous include how to implement and what happens during each type of duplexing methods, duplexing structures for supported duplexing methods: async duplexing, SM duplexing, user managed duplexing, You will hear how some capabilities and parameters will rescue you from a complex problematic situation. Come to this session to hear all these and more.
