Appendix D. System monitoring with MC/ServiceGuard (operating a cluster)

MC/ServiceGuard is a Hewlett-Packard software product for building clustering systems. Cosminexus HTTP Server can be operated on a clustering system using MC/ServiceGuard. For details on MC/ServiceGuard, see the MC/ServiceGuard documentation. Also, for details on how to operate required software (such as the OS) and related programs (such as CGI programs) for Cosminexus HTTP Server in a clustering configuration environment, see the documentation for each program.

MC/ServiceGuard allows you to operate a Web server with minimum content-delivery outage times caused by hardware failures or abnormal software stoppages. You can also administer, maintain, and upgrade software without stopping services.
