  • A properly configured parallel sysplex can deliver near continuous availability. Often "properly configured" is equated with redundancy. Yes, redundancy is certainly a critical factor for enabling a sysplex to deliver on its promise of availability. But it is not sufficient.  What one really needs is for the sysplex to be resilient. That is, the sysplex needs to be able to quickly resume normal operation after experiencing illness (such as sympathy sickness), change (such as reconfiguring of hardware or software), or misfortune (such as failures). In this presentation, we take redundancy as a given and explore ways to improve the resiliency of the sysplex. The topics were selected based on real world customer experiences.  In particular we look at things like Sysplex Failure Management (SFM) parameters, the use of BCPii to detect failed systems, procedures for upgrading Coupling Facilities, Health Checks, and more.
