To run DTM instances in separate DTM processes on the local node, configure the Data Integration Service to launch jobs in separate local processes. Configure DTM instances to run in separate DTM processes on the local node when the Data Integration Service runs mapping, profile, and workflow jobs on a single node or on a grid where each node has both the service and compute roles.
When the Data Integration Service runs jobs in separate local processes, stability increases because an unexpected interruption to one job does not affect all other jobs.
