Example Grid that Runs Jobs in Local Mode

Example Grid that Runs Jobs in Local Mode

In this example, the grid contains three nodes. All nodes have both the service and compute roles. The Data Integration Service is configured to run jobs in separate local processes.
The following image shows an example Data Integration Service grid configured to run mapping, profile, workflow, and ad hoc jobs in separate local processes:
The Data Integration Service grid contains three nodes. Each node has both the service and compute roles. The master service process runs on Node1. Worker service processes run on Node2 and Node3. Workflow jobs run in the master service process on Node1. Deployed mappings, mappings from Mapping tasks, mappings from profiles, and previews can run in separate DTM processes on each node.
The Data Integration Service manages requests and runs jobs on the following nodes in the grid:
  • On Node1, the master service process runs the workflow instance and non-mapping tasks. The master service process dispatches mappings included in Mapping tasks from workflow1 to the worker service processes on Node2 and Node3. The master service process also acts as a worker service process and completes jobs. The Data Integration Service dispatches a preview request directly to the service process on Node1. The service process creates a DTM instance within a separate DTM process to run the preview job. Mapping and profile jobs can also run on Node1.
  • On Node2, the worker service process creates a DTM instance within a separate DTM process to run mapping1 from workflow1. Ad hoc jobs can also run on Node2.
  • On Node3, the worker service process creates a DTM instance within a separate DTM process to run mapping2 from workflow1. Ad hoc jobs can also run on Node3.
