DTM process performs the following tasks
-
Retrieves and validates session information from the repository
-
Verifies connection object permissions
-
Sends a request to start worker DTM processes on other nodes when the session is configured to run on a grid
-
Adds partitions to the session when the session is configured for dynamic partitioning
-
None of the Above
The DTM (Data Transformation Manager) in Informatica PowerCenter performs multiple critical tasks: it retrieves and validates session configuration from the repository (A), verifies that the integration service has proper permissions on connection objects (B), coordinates worker DTM processes across grid nodes for parallel execution (C), and dynamically adds partitions when dynamic partitioning is enabled (D). All four tasks are core DTM responsibilities.
