Osservazioni
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 Utilizzo di parametri nel file di configurazione di un'istanza.
Esempio
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>
