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 parameter defaults in the ADF. It defines a SysName value that replaces any %SysName% string elsewhere in the ADF and a RetryInterval value that replaces any %RetryInterval% string elsewhere in the ADF.

<ParameterDefaults>
    <Parameter>
        <Name>SysName</Name>
        <Value>SERVER01</Value>
    </Parameter>
    <Parameter>
        <Name>RetryInterval</Name>
        <Value>P0DT00H15M00S</Value>
    </Parameter>
</ParameterDefaults>

As a result, if the ADF has the following for a SystemName element:

<SystemName>%SysName%</SystemName>

Microsoft SQL Server Notification Services will replace the parameter when you create the instance so that the effective SystemName definition is this:

<SystemName>SERVER01</SystemName>
