Settings
A production typically includes a large number of settings. Settings are configurable values that control the behavior of a production. Settings can affect a production in many ways. For example, a setting can specify:
-
The TCP port on which a business service should listen.
-
How frequently to check for new input.
-
The external data source name (DSN) to use.
-
The TLS configuration to use when connecting to an external entity.
-
How long to stay connected.
-
And so on.
An important feature of InterSystems IRIS is that a system administrator can modify settings while a production is running. The changes take effect immediately. The following shows an example of the web page that the system administrator uses to make such changes:
The production and its business hosts have settings provided by InterSystems IRIS; they correspond to properties of the production and business host classes. You can define additional settings in exactly the same way, by defining your own subclasses of InterSystems IRIS classes. You can also remove settings so that the corresponding properties are hardcoded and not configurable.
