ICMF
This is a special communication method that can be used to transport transactions to part of the MIMplex. ICMF is used only with the CA MIC component. This method can be used to transmit console messages between z/OS systems that do not communicate with each other through the control file.
Benefits
- Allows the MIMplex systems to be any combination of sysplexed and non-sysplexed images
- Allows message and command traffic to be exchanged among geographically remote systems
- Is not subject to contention delays associated with DASD I/O
- Requires no coupling facility structure control file
- Requires no shared DASD control file
- Reverts automatically to the CA MIM control file in the event of a CA‑L‑Serv route or VTAM cross-domain failure
Requirements
- VTAM cross-domains connecting desired systems
- CA‑L‑Serv product running as a separate started task
- For use with only the CA MIC component
