Overview

CA MIC is the component of the CA MIM product that provides you with cross-system command and message routing services in a multiple-system or multiple-image environment.

CA MIC provides the following:

• Allows you to issue commands from a local command source to one or more external systems and receive the responses back to the local command source.
• Allows you to import messages from external systems and route them to local destinations.
• Allows you to create a statistical report concerning CA MIC activity using a report facility.
• Provides cross-system communication in the following ways:
  • Through a shared DASD control file
  • Through CTC devices
  • Through XCF
  • By activating the ICMF, which interfaces with the communication server component of CA L-Serv. Both GCMF and ICMF must be activated to communicate through CA L‑Serv

CA MIC consists of the following facilities:

• Global Command and Message Facility (GCMF)

  The GCMF allows you to route messages and commands to any or all systems in a complex

• Intersystem Communication Facility (ICMF)

  The ICMF provides cross-system transaction routing services for CA MIC. ICMF interfaces with the CA L-Serv product, XMVS, which transports CA MIC data through VTAM cross-domains. This communication option is particularly useful to customers who want to transport messages and commands between geographically remote systems.

  Geographically remote systems typically do not have the shared DASD or CTC connectivity required by the other CA MIM communication options. ICMF can be activated as a stand-alone communication option or used in conjunction with the other communication options.
