This server offers technical services require by terminal handlers during user connection and disconnection phases.

The technical services are offered using internal message oriented services such connect and disconnect:

• connect performs various initialization tasks such as attributing the user Session ID and Terminal_ID.
• disconnect manages final tasks during disconnection.

The connection server also provides a few classical CICS transactions:

• CESN: the Sign oN transaction
• CESF: the Sign ofF transaction
• CSGM: the Good Morning transaction (default Good Morning transaction)

Specifically, ARTCNX handles the request from ARTTCPH and ARTSTRN/ARTSTR1, LUNAME validation check, and TERMID/LUNAME assignment. All services that ARTCNX publishes and their functionalities in the following list.

• gensess generates a session ID for each terminal; the session ID is maintained internally in ART CICS.
• delsess frees session ID when its terminal terminates.
• connect generates a locally unique (unique in each CICS region) TERMID and a globally unique LUNAME (unique in all CICS regions) for auto-install terminal, checks LUNAME validation for the LUNAME specified terminal, and changes TERM status to ACQUIRED.
• disconnect frees TERMID and LUNAME, and change TERM status to RELEASED.
• inquire handles INQUIRE NETNAME/TERMID request from ARTSTRN.
• update handles SET TERMINAL request from ARTSTRN.
• authfail outputs the error message in terminal if CESN logon fails.
• CESN specifies the Sign oN transaction
• CESF specifies the Sign ofF transaction
• CSGM specifies the Good Morning transaction (default Good Morning transaction)
• If ISC_ENABLE=YES is set, gensess and delsess will be published by ARTLOGN instead.
