ARTCTRN servers present application transactions as Tuxedo services and when receiving a transaction request, execute the corresponding programs.

These programs are screen less programs which cannot interact directly with the terminal user.

In contrast to ARTSTRN servers, these servers are transactional in order to manage true CICS transactions. They are only called from other servers (CONVERSE) and never directly from terminals or clients.

When starting, a ARTCTRN server publishes one service per transaction it offers. These transactions are named {SysId}_{transaction_name}.

The {SysId} is the name of this region defined in the -s parameter.

1. When a user program calls a transaction, the KIX__CONVERSE function makes a tpacall to the corresponding transaction (service).
2. One ARTCTRN offering this service receives the request with the associated message, then processes the transaction.
3. The transactions ends and the server returns a message to the caller.

Only transactions belonging to no tranclasses, or to a tranclass with maxactive >1 are advertised by these servers.
