The default mapping configuration defines the default mapping deployment properties. The Data Integration Service runs a mapping using the default mapping configuration unless a reusable or custom mapping configuration is specified.

Configure a default mapping configuration in the Developer tool preferences.

Use a reusable mapping configuration to override the default mapping configuration when you run a mapping. The mapping configuration persists for the current mapping run.

Configure a reusable mapping configuration in the

Run Configurations

dialog box. Select the mapping configuration and run the mapping through the

Run Configurations

dialog box, or select the mapping configuration when you run the mapping using advanced options. You must select the mapping configuration each time that you run a mapping.

Use a custom mapping configuration to override the default mapping configuration when you run a mapping. The custom mapping configuration properties include only the Data Integration Service, operating system profile for the Data Integration Service, override tracing level, and optimizer level. The custom mapping configuration persists for the current mapping run.

Configure a custom mapping configuration in the

Run Mapping Using Advanced Options

dialog box. You must reconfigure the custom mapping configuration each time that you run a mapping.
