Monitoring CICS/FEPI Applications

The Front‑End Programming Interface (FEPI) provides terminal emulation using virtual terminals defined to a CICS region. These virtual terminals, called nodes, communicate with back‑end processes that run either in the same CICS region or in a remote region. Front‑end processes, which are coded with EXEC CICS FEPI commands, communicate with both real and virtual terminals.

CA InterTest for CICS lets both front‑end and back‑end processes be tested. However, the terminal IDs must be properly specified when breakpoints are set.
