Замечания
In your 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.
Пример
The following example shows how to define a SysName parameter. Wherever the string "%SysName%" appears in the ADF, Microsoft SQL Server Notification Services substitutes the value SERVER01.
<Parameter>
<Name>SysName</Name>
<Value>SERVER01</Value>
</Parameter>
As a result, if the ADF has the following for a SystemName element:
<SystemName>%SysName%</SystemName>
Notification Services will replace the parameter when you create the instance so that the effective SystemName definition is this:
<SystemName>SERVER01</SystemName>
