A Diagnosis of Self-Healing Systems

gManZboy writes "We've been hearing about self-healing systems for a while, but (as is usual), so far it's more hype than reality. Well it looks like Mike Shapiro (from Sun's Solaris Kernel group) has been doing a little actual work in this direction. His prognosis is that there's a long way to go before we get fully self-healing systems. In this article he talks a little bit about what he's done, points out some alternative approaches to his own, as well as what's left to do."

Re:The challenge of a truly self-healing system

Plenty of Sun's boxes have redundant power supplies.

If something goes wrong with one, the system should detect either too little or too much DC voltage or current coming from it, and switch to it's backup.

Your suggestion doesn't make much sense. Should mozilla know what to do if a usb mouse fails or is removed unexpectedly? Of course not, the mozilla developers expect that this will be taken care of.

Likewise when an correctably memory or disk error occurs... The memory controller or disk firmware should deal with it and the application should be none-the-wiser.
