Chapter 3 Connection and Communication Parameters
71
The Internet Assigned Numbers Authority has assigned the Adaptive Server
Anywhere database server port number 2638 to use for TCP/IP
communications. However, applications are not disallowed from using this
reserved port, and this may result in an addressing collision between the
database server and another application.
In the case of the database server, the ServerPort option designates the port
number on which to communicate using TCP/IP.
In a data source, the ServerPort option informs the client of the port or ports
on which database servers are listening for TCP/IP communication. The
client broadcasts to every port that is specified on the ServerPort parameter
to find the server.
The database server always listens on port 2638, even if you specify a
different port using a network communication parameter. Hence,
applications can connect to the database server without specifying a port
number. An exception is the HP-UX operating system, on which the server
does not listen on port 2638 if it is started on another port.
2638
1 Start a network database server:
dbsrv7 -x tcpip -n server1
Port number 2638 is now taken.
2 Attempt to start another database server:
dbsrv7 -x tcpip -n server2
The default port is currently allocated, and so the server starts on another
port.
Sessions parameter
NetBIOS. Server side only.
Sets the maximum number of clients that can communicate with the server at
one time through a single LAN adapter. The default setting is operating-
system specific. The value is an integer, with maximum value 254.
NetBIOS network software has a limit to the number of commands allowed
per machine. Adaptive Server Anywhere uses these NetBIOS commands,
and disallows further connections if the system has no more commands
available, even if this is less than the value of the Sessions parameter.
Operating system specific. On Windows NT, the default is 16.
