Rule Parameters are used to build data rules after monitored data retrieval. Rule Parameters enable you to create shifts, delineated by days, hours, and times, that control requests made by end users. They are pertinent to data rules created from historical monitored data because they contain the thresholds that are compared to the the historically gathered resources used.
In addition, Rule Parameters enable you to set thresholds. Thresholds are the maximum resources that are allowed for a shift. You can set thresholds for CPU seconds, number of rows returned in a report, elapsed time in seconds, and input/output units.
Note: Rule Parameters are set using the Resource Management Administration Tool when building rules for servers on all platforms.
The Parameter Properties window appears, as shown in the following image.

Reference: |
Rule parameters are sorted and prioritized for execution during the governing process, and rule parameters active for date ranges take priority over those for specific days. The rules are then executed in order of storage in the RMLSYS data source.
This methodology allows you to create shifts for special days, such as holiday weekends, which take precedence over the normal business-hour thresholds. For example, you can have one rule parameter for weekdays from 8 a.m. to 5 p.m., and another for weekends. For holiday weekends, when you may want to set thresholds higher, you would use a date range which would override the thresholds set for specific days.
Before you create rules or a knowledge base from monitored data, you need to create the shifts and thresholds that control the execution of requests against the data source.
The Parameter Properties window, as shown in the figure below, is available by right-clicking a shift and selecting Properties, or by double-clicking a shift.
The Parameters Properties dialog box has the following options for thresholds values:
The name of the rule parameter.
The time when these particular set of thresholds will be in effect.
Indicates whether the parameter will be used for making rules. The default setting is Active.
Is the maximum number of rows that a request can potentially return without being canceled.
Is the maximum number of wall clock seconds that a request can use without being canceled.
Is the maximum number of CPU seconds that a request can use without being canceled.
Is the maximum number of input/output units a request can generate without being canceled.
These days indicate what dates the shift will be in effect for.
You must save the shift information to the server for the change to take effect.
Note: If at any time in this process you decide you want to cancel the changes you have made, click the Refresh button, or the back button on the browser.
