Set Up Dual Import Policy Servers

We recommend that you deploy two Import Policy servers in hub mode, one to process imported files and the other to process imported emails. In hub mode, each server hosts Event Import and a hub. In turn, the two hubs pass imported files and e‑mails to a shared pool of policy engines. This setup allows maximum flexibility to distribute the policy processing load and to add additional policy engines if the volume of data captured by the NBA increases.

To set up Import Policy in hub mode, you use the Engine.UsePolicyEngineConnector=Hub import parameter. Each Event Import instance must have its own version of the import.ini file, one configured to import emails and the other to import files.

For full details about Import Policy, see the Deployment Guide; search the index for ‘Import Policy’.
