CHAPTER 3 Configuring the Operating System

For IBM RS/6000

The errpt command includes several options for limiting the report to events that match certain criteria. Use the errpt command on a regular basis. If errors appear, use the diagnostic tool diag to check your memory and disks. Or use the System Management Interface Tool (SMIT) to run the errpt command. This command may produce a lot of output.

For Sun Solaris

Check the /var/adm/messages file on a regular basis. If any of the types of hardware errors described in the beginning of this section appear, use the Sun Microsystems diagnostic tool, sundiag, to check memory and disks. See the operating system documentation for more information.

For Linux

Check the /var/log/messages file on a regular basis. See the operating system documentation for more information.

Monitoring the use of operating system resources

The System Administration Guide discusses maintaining the optimal number of Adaptive Server engines for your workload and system configuration. To determine the optimal number, monitor system and CPU usage.

For HP-UX

HP-UX supplies many tools to help monitor performance, some of which are described as follows:

•The sar command reports relative and absolute I/O throughput rates to each disk and controller.

•The vmstat command monitors virtual memory usage.

•The netstat command monitors network status.
