The Data Integration Service is an application service that performs data integration tasks for Informatica Analyst, Informatica Developer, and external clients. Data integration tasks include previewing data and running profiles, SQL data services, web services, and mappings.
When you start a command from the command line or an external client to run SQL data services and mappings in an application, the command sends the request to the Data Integration Service.
You can configure the Data Integration Service to run on the following domain objects:
On nodes
If your license includes high availability, you can configure the service to run on multiple nodes. By default, the service runs on the primary node. If the primary node is not available, the service runs on a back-up node. If the service process fails or the node becomes unavailable, the service fails over to another node. If your license does not include high availability, you can configure the service to run on one node.
On a grid
If your license includes grid, you can configure the service to run on a grid. A grid is an alias assigned to a group of nodes. The Data Integration Service dispatches jobs to available nodes assigned to the grid. When the Data Integration Service runs on a grid, the service remains available if a service process fails or a node becomes unavailable.
