Замечания
In your application definition file (ADF), you can use a parameter for any element's value. The parameter takes the form %ParameterName%. You can provide values for these parameters in two places:
- In the ADF ParameterDefaults section.
- In the instance configuration file (ICF) Application/Parameters section.
You can also use parameters within the ICF, which provides additional methods of supplying parameter values. For more information, see Использование параметров в файле конфигурации экземпляра.
The value of the Value element must match the format of the element for which it supplies a parameter. For instance, if the value provides data for an element that uses a duration data type, the value must follow the PnYnMnDTnHnMnS format.
Пример
The following example shows how to define a parameter called Duration
. Wherever the string "%Duration%" appears in the ADF, Microsoft SQL Server Notification Services substitutes the value P0DT00H15M00S
.
<Parameter>
<Name>Duration</Name>
<Value>P0DT00H15M00S</Value>
</Parameter>
As a result, if the ADF has the following for an ActionTimeout element:
<ActionTimeout>%``Duration``%</ActionTimeout>
Notification Services replaces the parameter when you create the instance so that the effective ActionTimeou definition is this:
<ActionTimeout>``P0DT00H15M00S``</ActionTimeout>
