PROMON Modify Defaults option

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.

The following shows the menu that appears when you choose the Modify Defaults option.

     Enter your selection: m

     3. Short pause after each page   : 4
     4. Long pause after last page    : 8
     5. Monitor Sampling Interval     : 30 sec.
     6. APW queue delay               : 500 ms.
     7. APW queue start               : 1
     8. APW scan delay                : 3 sec.
     9. APW scan count                : 9
     A. APW write limit               : 5
     B. BIW scan delay                : 0
     C. Group commit delay            : 10
     S. Sort user lists               : by user number

     Enter your selection:

The Modify Defaults menu provides the following options:

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.

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 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 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 Technical Support.

BIW scan delay — The value of the BI Writer Scan Delay startup parameter (-bwdelay). The default value, in seconds, is 0.

Group commit delay — The value of the Group Delay startup parameter (-groupdelay). The default value, in seconds, is 10.

Sort user lists — Toggles the user list sort between sorting by user number or tenant Id

Tenant filter for user lists — Allows you to filter by one or many tenants using the Currently Connect Tenants screen.
