Notes
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 Utilisation de paramètres dans un fichier de configuration d'instance (ICF).
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.
Exemple
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>
