In Separate DTM Processes on Remote Nodes

In Separate DTM Processes on Remote Nodes

To run DTM instances in separate DTM processes on remote nodes, configure the Data Integration Service to launch jobs in separate remote processes. Configure DTM instances to run in separate DTM processes on remote nodes when the Data Integration Service runs mapping, profile, and workflow jobs on a grid where nodes can have a different combination of roles.
When the Data Integration Service runs jobs in separate remote processes, stability increases because an unexpected interruption to one job does not affect all other jobs. In addition, you can better use the resources available on each node in the grid. When a node has the compute role only, the node does not have to run the service process. The machine uses all available processing power to run mappings.
The following image shows two of many nodes in a Data Integration Service grid. Node1 has the service role, and Node2 has the compute role. The Data Integration Service process on Node1 manages application deployments, logging, job requests, and job optimizations. The Service Manager on Node2 runs DTM instances in separate DTM processes started within containers.
Node1 has the service role and runs the master Data Integration Service process. Node 2 has the compute role and includes 2 containers. A DTM process with multiple DTM instances runs in each container.
