Predictive Self-Healing in the Solaris 10 Operating System

Sun has developed a new architecture for building and deploying systems and services capable of Predictive SelfHealing. Self-healing technology enables Sun systems and services to maximize availability in the face of software and hardware faults. It facilitates a simpler and more effective end-to-end experience for system administrators, reducing cost of ownership. The first self-healing features are available as part of the SolarisTM 10 Operating System (OS). This paper describes Sun’s approach to building self-healing systems as well as the new technologies available in the Solaris 10 OS. Beta versions of the Solaris 10 OS can be downloaded through the Software Express program beginning with the July 2004 release. For more information, visit sun.com/solaris/10. Solaris 10 Predictive Self-Healing Features • Automatic monitoring and diagnosis of CPU, memory, and I/O subsystems • Automatic offlining of faulty resources while the Solaris OS is running • Administrator tools to view self-healing logs and results • Standardized messaging for all self-healing diagnosis results • Knowledge article Web site linking to online diagnosis messages Solaris 10 Predictive Self-Healing Benefits • Improved system and service availability through predictive diagnosis and isolation of faulty components • Diagnosis of faulty components performed automatically, in some cases reducing analysis time from days to seconds • Simplified administration model for managing self-healing activities, reducing cost of ownership • Links to knowledge articles for learning more about problem impacts and repairs, updated in Internet time • Scalable architecture that can be rapidly adapted to new problems and updated without requiring system downtime
