{ dbeng12 | dbsrv12 } -x { all | none | tcpip [ ( parm=value;...) } ...

Regardless of which settings you choose for the -x option, the database server always accepts shared memory connections.

By default, the personal database server starts only the shared memory protocol, while the network database server starts the shared memory and TCP/IP protocols.

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

All operating systems and database servers.

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

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

For the TCP/IP protocol, additional parameters may be provided, in the following 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 or certain punctuation characters are used, such as round brackets. For example:

-x "tcpip(PARM1=value1;PARM2=value2;...)"

When the database server listens for TCP/IP connections, by default it listens to all network cards on port 2638. See Network protocol options.

• Examples of starting a database server
• -xd dbeng12/dbsrv12 server option
• -xp dbsrv12 database option
• -xs dbeng12/dbsrv12 server option
• CommLinks (LINKS) connection parameter
• TCP/IP protocol

Allow shared memory and TCP/IP connections on the network server:

dbsrv12 -n server_name "%SQLANYSAMP12%\demo.db"

Use the -x option to specify protocol options to tune the behavior of TCP/IP. Allow the network server to use two specific network cards:

dbsrv12 -x "tcpip(MyIP=192.75.209.12,192.75.209.32)" "%SQLANYSAMP12%\demo.db"

Allow shared memory and TCP/IP connections on the personal server:

dbeng12 -x tcpip "%SQLANYSAMP12%\demo.db"
