备注
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 使用实例配置文件中的参数.
示例
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>
