The Bridge provides the flexibility to directly modify xUML service settings that have been defined with the Builder in component or activity diagrams without re-deploying the xUML service. After the first deployment of the xUML service, the settings can be overwritten on the Settings tab.

Switch to the Settings tab in the information/working area.
Users with administration rights are allowed to view and modify the xUML service settings of any xUML service. Users who are member of a group, to which the role MODELER has been assigned, are only allowed to view and modify them, if they themselves or a member of the same group deployed the xUML service.

The settings are grouped. Initially, the Bridge displays the settings of the first settings group Settings/Deployment Macros.
Select the group of settings you want to change.

The settings are categorized into the following:

• Global Settings
  In this category, you can change setting values that are global to the xUML service. Deployment information retrieved with deployment macros can be overwritten in this category, too (see Global Settings below).

• Add-ons
  In this category, the settings comprise add-on related values like tagged values, interface URIs, and others. For instance, data of the SQL adapter, File System adapter, Timer, or SOAP service request may be overwritten. For more details, refer to the example in Add-on Settings.

Within a settings category, select a settings group you want to modify settings in.

Change settings and click Apply to apply your changes. Click View to refresh the working area. Click Export as CSV to export all settings to an Excel sheet.

Global Settings

xUML Service Settings

You can define name-value pairs with the setting macro in an activity diagram, or initial values of class attributes having the tagged value setting set to true. Having defined settings in the xUML model like that, you can modify these values on the Bridge here.

Click Apply after you have changed the values.
Changed values are displayed in bold. The original values coming from the UML model are displayed in a separate column for you to compare the original value and the changed value.

Refer to the example mentioned below for more details.

Add-on Settings

Each xUML service adapter has its own settings that are initialized in the xUML model and can be changed here. The general context of the add-on settings is explained with the SQL ODBC example.

If you are running an xUML service that is connecting to a database backend, you can modify the tagged values of the database interface respectively dependency (see picture below). In this example, the key values displayed on this page correspond to the tagged values that have been defined in the UML model.

Before starting a deployed xUML service that connects to a database backend, you may want to redefine required database parameters on the Bridge.

SQL Adapter Connection Settings

Select the xUML service in the navigation on the left (in this example CustomerQuery). Switch to tab Settings and select the option SQL Adapter Connection in the Add-ons category from the drop-down list.

The default parameters are defined in the component diagram of the xUML service (see example ODBCExample below). The connection is defined by the xUML named ODBCExample and the SQL Alias named customers. The database user and password are defined in the tagged value user on the alias.

Key	Value
customers:DBType	Name of the SQL Service component, e.g. SQLite
customers:DBName	Name of the database, e.g. ScheerACME_Customers
customers:Connection Pooling
customers:Max Connection Reuse
customers: Max Connection Age
customers: Max Connection Idle Time

For more information on the SQL adapter settings (other tagged values, default values, ...) refer to SQL.

SQL Adapter Authorization Settings

Now, select SQL Adapter Authorization from the list.

These settings allow you to adapt the SQL database user and password of the xUML service.

Overview on other Add-on Settings

Generally, most of the add-on settings that are related to an xUML Service Adapter have a corresponding tagged value in the component diagram (as described above with help of the SQL ODBC example). Have a look at the documentation pages of the corresponding adapter for these settings.

Find below a list of other add-on settings and their description. For the sake of completeness, we also mentioned settings coming from the model for some setting groups (see column Specified in Model on).
