TDM uses a Data Integration Service to perform data discovery. You must connect to a Data Integration Service within the Informatica domain and enable data profiling before users can run data discovery profiles. By default, data profiling is disabled in Test Data Manager.
You can connect to a Data Integration Service within the Informatica domain. Specify the Data Integration Service to connect to and enable data profiling when you create the Test Data Manager Service from the Administrator tool. You can edit the Test Data Manager Service properties and connect to a different Data Integration Service in the domain if you need to.
See the Informatica
Test Data Management Installation Guide
for information on how to edit the Test Data Manager Service.
