guys can you tell me how to "close" a connection to Oracle? I am using nca_connect_server function, then i got this error message when I ran it in mutiple iteration:
nca_connect_server: cannot establish a new connection without closing the old one

so i am not sure how to close the db connection, there is no nca_close function, but there is nca_logon_cancel but it requried a logon server not sure
