This option allows you to turn broadcast listening off for this port.
Using -sb 0 is the same as specifying BroadcastListener=NO on TCP/IP.
If broadcast listening is off, then the database server does not respond to UDP broadcasts. This means that clients must use
either the HOST protocol option to specify the hostname of the database server, or register the database server with LDAP
and use LDAP on the clients to find the database server. This also means that the dblocate utility does not include the database
server in its output.
