备注
The ParameterDefaults section is where you define default values for parameters used in the ICF. Anywhere the parameter appears in the ICF, Notification Services substitutes the value.
For example, you might use the same directory path in multiple locations in your ICF. Instead of typing the path in each location, and then having to change it in each location, you can use a parameter, such as %BaseDirPath%. Then, in the ParameterDefaults section of the ICF, you define the value once, as shown in the example below.
You can override ParameterDefaults values by specifying a parameter name and value when creating or updating the instance.
If you do not specify default values for parameters, omit the entire ParameterDefaults section from the ICF or use empty tags for the child elements.
示例
This example shows a complete ParameterDefaults element with two default values. Notification Services substitutes "C:\NS" wherever %BaseDirPath% appears in the ICF and substitutes "SQL10" wherever %DBSystem% appears in the ICF.
<ParameterDefaults>
<Parameter>
<Name>BaseDirPath</Name>
<Value>C:\NS</Value>
</Parameter>
<Parameter>
<Name>DBSystem</Name>
<Value>SQL10</Value>
</Parameter>
</ParameterDefaults>
