Displays terminal behavior parameters and lets you change them when running the monitor. It also displays and lets you change the value of startup parameters used for tuning the asynchronous page writer.
Figure 19–15 shows the menu that appears when you choose the Modify Defaults option.

DISPLAY FIELDS
Page size
The number of lines on the terminal screen.
Clear screen for first page
If Yes, the system clears the screen before the main menu and before every list.
Short pause after each page
The delay in seconds between pages of output when in continuous monitoring mode. (Enter u for the Continue Uninterrupted option.)
Long pause after last page
The delay after the last page of output when in continuous monitoring mode.
For example, if you choose option 7 (Database Status), wait for first page of output, and enter u, then by default:
Monitor Sampling Interval
The interval at which PROMON samples data, in seconds.
APW queue delay
The value of the Page Writer Queue Delay (-
pwqdelay
) startup parameter.-pwqdelay
is a self-tuning parameter. When the database encounters heavy loads,-pwqdelay
decreases its value so that the APW writes more often. When the demand on the database lessens,-pwqdelay
increases its value so that the APW writes less often. The default value, in milliseconds, for-pwqdelay
is 100.APW queue start
The value of the Page Writer Queue Minimum (-
pwqmin
) startup parameter. Do not change this value unless directed to do so by Progress Software Technical Support.APW scan delay
The value of the Page Writer Scan Delay (-
pwsdelay
) startup parameter. The default value, in seconds, of-pwsdelay
is 1.APW scan count
The value of the Page Writer Scan (-
pwscan
) parameter. Do not change this value unless directed to do so by Progress Software Technical Support.APW write limit
The value of the Page Writer Maximum Buffers (-
pwwmax
) parameter. Do not change this value unless directed to do so by Progress Software Technical Support.
