Appendix E. System monitoring with HACMP for AIX (operating Cluster Multi-Processing)

HACMP for AIX is a software product developed by IBM, for building a mission-critical computing platform. HACMP for AIX has two main components, High Availability (HA) and Cluster Multi-Processing (CMP). Cosminexus HTTP Server can be operated through Cluster Multi-Processing by using HACMP for AIX. For details on HACMP for AIX, see the HACMP for AIX 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 Cluster Multi-Processing (CMP) configuration, see the manuals for each program.

HACMP for AIX 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.

Main failures monitored
The main failures monitored by HACMP for AIX are as follows:
  • LAN failures
  • Resource failures (system processor, disk, interface)
  • Abnormal software stops
