The interface layer

Adapter (DFHDBAT)
Control is passed to the database adapter transformer, DFHDBAT, through the CICS® resource manager interface (RMI). It is the responsibility of the adapter to construct the DRA INIT, DRA TERM, and DRA THREAD parameter lists from the RMI parameter list passed to it. It must also transform the DRA parameter list that was passed back after a DL/I call to the format expected by CICS.
