Example Grid that Runs Jobs in Remote Mode

Example Grid that Runs Jobs in Remote Mode

In this example, the grid contains three nodes. Node1 has the service role only. Node2 has both the service and compute roles. Node3 has the compute role only. The Data Integration Service is configured to run jobs in separate remote processes.
The following image shows an example Data Integration Service grid configured to run mapping, profile, workflow, and ad hoc jobs in separate remote processes:
The Data Integration Service grid contains three nodes. Node1 has the service role only and runs the master service process. Workflow jobs run in the master service process on Node1. Node2 has both the service and compute roles and runs the worker service process. Mapping optimizations and compilations occur on Node2. Preview jobs run on Node2. Node3 has the compute role only and is designated the master compute node. Deployed mappings, mappings from Mapping tasks, and mappings from profiles run on Node3 in separate DTM processes started within a container.
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 a mapping included in a Mapping task from workflow1 to the worker service process on Node2. The master service process also acts as a worker service process and can optimize and compile mappings. Profile jobs can also run on Node1.
  • On Node2, the worker service process optimizes and compiles the mapping. The worker service process then communicates with the master compute node on Node3 to dispatch the compiled mapping to a worker compute node. The Data Integration Service dispatches a preview request directly to the worker service process on Node2. The service process creates a DTM instance within a separate DTM process on Node2 to run the preview job. Node2 also serves as a worker compute node and can run compiled mappings.
  • On Node3, the Service Manager on the master compute node orchestrates requests to run mappings. The master compute node also acts as a worker compute node and runs the mapping from workflow1 in a separate DTM process started within a container.
