Mapping Configurations

Mapping Configurations

A mapping configuration controls the mapping deployment properties that the Developer tool uses when you run a mapping.
You can configure a default mapping configuration, a reusable mapping configuration, or a custom mapping configuration. The default mapping configuration specifies the default mapping properties. The Data Integration Service uses the default mapping configuration to run a mapping unless a reusable or custom mapping configuration is specified.
The following table describes the mapping configuration types:
Mapping Configuration
Description
Default mapping configuration
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.
Reusable mapping configuration
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.
Custom mapping configuration
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.
