Default configuration values and environment properties
At start up, PolicyCenter requires many parameters. Consider this
carefully if you specify parameters by environment. In some cases, you might want to specify a
configuration parameter without any
env or server attribute
to ensure that the parameter always resolves to some value. In the following example, the last
line always resolves to a known value if the other two parameter lines do not resolve:<param name="ClusteringEnabled" value="false" server="batch, ui, workqueue" /><param name="ClusteringEnabled" value="true" env="test" /><param name="ClusteringEnabled" value="true"/>
The last line setting in this example acts as the default value for the parameter. Of course, you might want the server to start only if a certain environment is available. In this case, a default is inappropriate.
