If your license includes grid, you can configure the Data Integration Service to run on a grid. A grid is an alias assigned to a group of nodes that run jobs.
When the Data Integration Service runs on a grid, you improve scalability and performance by distributing jobs to processes running on multiple nodes in the grid. The Data Integration Service is also more resilient when it runs on a grid. If a service process shuts down unexpectedly, the Data Integration Service remains available as long as another service process runs on another node.
When the Data Integration Service runs on a grid, the service and compute components of the Data Integration Service can run on the same node or on different nodes, based on how you configure the grid and the node roles. Nodes in a Data Integration Service grid can have a combination of the service only role, the compute only role, and both the service and compute roles.
A Data Integration Service that runs on a grid can run DTM instances in the Data Integration Service process, in separate DTM processes on the same node, or in separate DTM processes on remote nodes. Configure the service based on the types of jobs that the service runs.
