Intersystem Communication Facility

The Intersystem Communication Facility (ICMF) is the CA MIC facility used to transmit data (messages and commands) through the communication server of CA L-Serv. The communication server component of CA L-Serv transmits data between systems connected through VTAM. The ICMF communication method can only be used by CA MIC to transmit data.

You can use this method as your exclusive cross-system communication method, or together with other communication methods.

If the CA L-Serv route is active between two systems, then CA MIC chooses the ICMF method over other available communication methods (such as CTCDASD, CTCONLY, DASDONLY, and XCF) that may be available. If the CA L-Serv route is deactivated, then CA MIC automatically begins transmitting data using the other communication method, if available.

Note: For more information about installing and using CA L-Serv, see the CA L-Serv documentation.
