Tru64 Unix-Oracle9i Cluster Quick Reference

For best overall system performance, an interative process of monitoring and tuning takes place over a period of time. This chapter describes the common performance monitoring tools available in Tru64 UNIX with several examples. Tru64 UNIX contains a very strong set of standard tools included with the operating system installation. Additional performance monitoring tools are available on the internet or the additional product CD-ROM.
It is important to monitor CPU activity, memory, and disk I/O with normal system activity. For data warehouses, monitor aggregate I/O throughput; for transactional systems, monitor I/O operations per second. Monitor memory usage and watch the available free memory.

System monitoring also includes routine system error monitoring, looking for any hardware or software failures in the Tru64 UNIX error logs. In Table 9-1 is a list of subsystems and the appropriate tools for each. Optional tools can be downloaded from the Compaq Web site listed in Figure 9-1.
