2.2 Communications Resource Manager

The CRM runs as a separate native process. It enables APPC conversations and DPL protocols to flow into and out of the ATMI environment. The CRM obtains its configuration from the Gateway. If the Gateway is running on a platform other than the one on which the CRM is running, the CRM should be started before the ATMI platform is started so it will be monitoring the address specified in the Gateway configuration.

A properly configured SNA protocol stack is required for the CRM to communicate with a mainframe, unless the CRM is running independently of the ATMI environment (distributed mode).
