-x dbeng12/dbsrv12 server option

{ dbeng12 | dbsrv12 } -x { all | none | srv-protocols } ...

srv-protocols:
    { tcpip parmlist },...
parmlist:
    ( parm=value;...)

Regardless of which settings you choose for the -x option, the database server always listens for connection broadcasts using the shared memory protocol.

By default, the personal database server starts only the shared memory protocol, while the network database server starts all available protocols.

You can also specify the following values for the -x option:

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 usually ensures a connection.

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).

All operating systems and database servers.

Use the -x option to specify which communications protocols you want to use to listen for client connection broadcasts.

If you do not specify the -x option, the personal database server attempts to listen for client connection broadcasts using shared memory, and the network database server attempts to listen for client broadcasts using shared memory and TCP/IP.

For information about securing shared memory connections on Unix, see Security tips.

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 shared memory and TCP/IP communications:

dbsrv12 -x tcpip

-x dbeng12/dbsrv12 server option
