Mappings

Mappings

The Applications view displays mappings included in applications that have been deployed to the Data Integration Service.
Mapping properties include read-only general properties and properties to configure the settings the Data Integration Services uses when it runs the mappings in the application.
The following table describes the read-only general properties for mappings:
Property
Description
Name
Name of the mapping.
Description
Short description of the mapping.
Type
Type of the object. Valid value is mapping.
Location
The location of the mapping. This includes the domain and Data Integration Service name.
The following table describes the configurable mapping properties:
Property
Description
Date format
Date/time format the Data Integration Services uses when the mapping converts strings to dates.
Default is MM/DD/YYYY HH24:MI:SS.
Enable high precision
Runs the mapping with high precision.
High precision data values have greater accuracy. Enable high precision if the mapping produces large numeric values, for example, values with precision of more than 15 digits, and you require accurate values. Enabling high precision prevents precision loss in large numeric values.
Default is enabled.
Tracing level
Overrides the tracing level for each transformation in the mapping. The tracing level determines the amount of information the Data Integration Service sends to the mapping log files.
Choose one of the following tracing levels:
  • None. The Data Integration Service uses the tracing levels set in the mapping.
  • Terse. The Data Integration Service logs initialization information, error messages, and notification of rejected data.
  • Normal. The Data Integration Service logs initialization and status information, errors encountered, and skipped rows due to transformation row errors. It summarizes mapping results, but not at the level of individual rows.
  • Verbose Initialization. In addition to normal tracing, the Data Integration Service logs additional initialization details, names of index and data files used, and detailed transformation statistics.
  • Verbose Data. In addition to verbose initialization tracing, the Data Integration Service logs each row that passes into the mapping. The Data Integration Service also notes where it truncates string data to fit the precision of a column and provides detailed transformation statistics. The Data Integration Service writes row data for all rows in a block when it processes a transformation.
Default is None.
Optimization level
Controls the optimization methods that the Data Integration Service applies to a mapping as follows:
  • None. The Data Integration Service does not optimize the mapping.
  • Minimal. The Data Integration Service applies the early projection optimization method to the mapping.
  • Normal. The Data Integration Service applies the early projection, early selection, and predicate optimization methods to the mapping.
  • Full. The Data Integration Service applies the early projection, early selection, predicate optimization, and semi-join optimization methods to the mapping.
Default is Normal.
Sort order
Order in which the Data Integration Service sorts character data in the mapping.
Default is Binary.
