ARTIMPP is a Tuxedo server to act as both service handler and container for COBOL/C programs of TP type. There are two running modes for ARTIMPP, one is ARTIMPP in normal mode (without -p in CLOPT), another is ARTIMPP in persistent mode (with -p in CLOPT).

ARTIMPP in normal mode invokes corresponding COBOL/C program according to the service request received from front end (request from terminal, ARTIGW).

ARTIMPP in persistent mode will monitor /Q for persistent transaction whose class is defined in the "-l class_list" parameter in CLOPT for the ARTIMPP. It will get the message from the /Q and invoke corresponding COBOL/C program.
