The simplist method might be to incorporate Oracle into the software that looks at the trunstile/com ports eg proC.

Basically, it should be straight forward.

A significant issue may be if the database is shutdown for a time while the turnstile software is running. You need the environment variable ( .. main(argv, argc... , environment) ) which most people ignore to restart the connection to the Oracle database. I cannot recall the exact function call, but I recall that not having the enviroment variable made a reconnect impossible once the database shutdown. The oposite condition - the program disconnects from Oracle and reconnects is handled easily by the connect/disconnect statements.
