Before You Configure a Data Integration Service Grid

Before You Configure a Data Integration Service Grid

Before you configure a Data Integration Service to run on a grid, complete the prerequisite tasks for a grid.

Define and Add Multiple Nodes to the Domain

Run the Informatica installer on each machine that you want to define as a node in the Data Integration Service grid. The installer adds the node to the domain with both the service and compute roles enabled. When you log in to the Administrator tool, the node appears in the Navigator.

Verify that All Grid Nodes are Homogeneous

All machines represented by nodes in a Data Integration Service grid must have homogeneous environments. Verify that each machine meets the following requirements:
  • All machines must use the same operating system.
  • All machines must use the same locale settings.
  • All machines that represent nodes with the compute role or nodes with both the service and compute roles must have installations of the native database client software associated with the databases that the Data Integration Service accesses. For example, you run mappings that read from and write to an Oracle database. You must install and configure the same version of the Oracle client on all nodes in the grid that have the compute role and all nodes in the grid that have both the service and compute roles.
    For more information about establishing native connectivity between the Data Integration Service and a database, see Configure Native Connectivity on Service Machines (shared).

Obtain an External HTTP Load Balancer for Web Service Requests

To run web service requests on a Data Integration Service grid, you must obtain and use an external HTTP load balancer. If you do not use an external HTTP load balancer, web service requests are not distributed across the nodes in the grid. Each web service request runs on the node that receives the request from the web service client.
