The ACUODBCS_PORT variable specifies a particular port number to be used for accessing acuodbcs on the server host machine. This is especially helpful when the server has a security firewall, because firewalls generally allow access only to specific ports. With this variable, the site can ensure that firewall restrictions are satisfied.
The acuodbcs daemon can work with privileged port numbers (from 0 to 1023) and with non-privileged port numbers (1024 and higher, up to 32767).
Users can override the value of this variable by assigning a port number on the command line (via the "-n" option) when the daemon is started.
