Validating Dynamic Sources and Targets

Validating Dynamic Sources and Targets

Validate the sources and targets in a dynamic mapping to ensure that the Data Integration Service can read and process the entire mapping when a source or target synchronizes with a relational database at run time.
To validate the sources and targets, resolve the mapping parameters and validate the generated instance of the mapping that contains the resolved parameters. The mapping must be valid before you resolve the mapping parameters.
To resolve mapping parameters, parameters must be configured in the mapping. If parameters are not configured, you cannot validate the dynamic sources and targets.
  1. In the Developer tool, right-click a mapping in the editor or the Object Explorer view. Select
    Show Mapping with Resolved Parameters
    .
    The
    Show Mapping with Resolved Parameters
     dialog box appears.
    This dialog box shows the options that you can use to resolve mapping parameters. You can select to resolve the parameters using the default values in the mapping, a parameter set, or a parameter file.
  2. Select one of the following mapping parameters options:
    • Apply the default values in the mapping. The Data Integration Service applies the default parameter values configured in the mapping.
    • Apply a parameter set. The Data Integration Service applies the parameter values configured in the parameter set.
    • Apply a parameter file. The Data Integration Service applies the parameter values configured in the parameter file.
  3. Click
    OK
    .
    The Developer tool generates the run-time instance of the mapping. The run-time mapping appears in a new tab.
  4. Right-click the run-time instance of the mapping and select
    Validate
    .
    If errors appear in the
    Validation Log
     view, fix the errors and validate the mapping again.
  5. When the mapping is valid, click
    File
    Save
     to save the mapping.
  6. Re-validate the mapping after the source schema has changed or after you change the parameter values.
