CHAPTER 13 Monitoring and Tuning Performance

When you run the monitor again from the same database and connection number, by default it overwrites the previous results. If you need to save the results of a monitor run, copy the file to another location before starting the monitor again from the same database or use the -appendoption.

Examples of monitor results

Example of -summary option

This section shows sample results using different monitor options.

The -summaryoption produces results like the following. Note that it shows both main and temp buffer cache statistics, no matter which you request in the IQ UTILITIES command:

Options string for private cache: "-summary -interval 5"
