Specifies server side network communications protocols.
dbsrv11 -x { all | none | srv-protocols } ...
srv-protocols: { tcpip parmlist },... parmlist: ( parm=value;...)
dbeng11 -x { all | none | eng-protocols } ...
eng-protocols: { tcpip [ parmlist ] },... parmlist: ( parm=value;...)
All operating systems and database servers.
Use the -x option to specify which communications protocols, in addition to shared memory, you want to use to listen for client connection broadcasts.
If you do not specify the -x option, the server attempts to listen for client connection broadcasts using all protocols supported by the database server running on your operating system, including shared memory.
If you specify the -x option with one or more protocols, the server attempts to listen for client connection broadcasts using the specified protocol(s) and also using a shared memory protocol.
For information about securing shared memory connections on Unix, see Security tips.
If you are running Windows Mobile and specify the -x option, the server only attempts to listen for client connection broadcasts using the TCP/IP protocol unless you explicitly request otherwise.
Regardless of which settings you choose for the -x option, the server always listens for connection broadcasts using the shared memory protocol. In addition to the shared memory protocol, you can also specify the following:
ALL Listen for connection attempts by the client using all communications protocols that are supported by the server on this platform, including shared memory. This is the default.
NONE Listen for connection attempts by the client using only the shared memory protocol.
TCPIP (TCP) Listen for connection attempts by the client using the TCP/IP protocol. The TCP/IP protocol is supported by the network server on all operating systems, and by the personal database server for same-computer communications.By default, the database server listens for broadcasts on port 2638, and redirects them to the appropriate port. This ensures a connection in most cases.
You can override this default and cause the server not to listen on port 2638 by setting the option -sb 0, or by turning off the BroadcastListener option (BroadcastListener=0). Additionally, if the client and server are communicating through a firewall, the client must send the packet to the exact port the server is listening on by specifying DoBroadcast=None and Host=.
See ServerPort protocol option [PORT].
For some protocols, additional parameters may be provided, in the format
-x tcpip(PARM1=value1;PARM2=value2;...) |
For more information about available parameters, see Network protocol options.
For Unix, quotation marks are required if more than one parameter is supplied:
-x "tcpip(PARM1=value1;PARM2=value2;...)" |
Allow only shared memory and TCP/IP communications:
-x tcpip |
