Viewing and Editing Configuration Variables

You can edit and view configuration variables in the Configuration Variables View. This view displays the deployed models in a table. Each model name can be expanded to reveal the configuration variables for the model and their values, which can be edited directly in the table.

The configuration variables can be defined in the modeler, please refer to the chapter Using Configuration Variables in the Stardust Online Documentation - Modeling Guide Using Configuration Variables of the Modeling Guide for details.

Table Entries

The Configuration Variables table provides the following entries:

• Model - expandable node containing the model ID of the deployed model.
• Name - the name of the Configuration Variable.
• Value - the value of the Configuration Variable in the Preferences Store. If it is empty, the default value is used. The value is editable.
• Default Value - default value, which is used if a value is no specified. The default value is not editable.
• Description - the description of the configuration value.

If the Description is added in the Properties page for the model in modeler, then it is displayed as tooltip text in the portal when you hover the mouse over the model name.

Hiding / Showing Obsolete Configuration Variables

By default, all configuration variables are displayed regardless of whether they are used in the currently deployed model(s) version or not. In case you like to hide the configuration variables that were created for older model versions, but are not used in the currently deployed model(s), click the Show / Hide Configuration Variables icon in the toolbar.

For example, having a configuration variable CentralServer, that is not used in the currently deployed model anymore. To hide this variable in the table, the Show / Hide Configuration Variables icon is clicked.
