Client-server/Network options page
This page groups together parameters related to the use of the database in client-server mode. Naturally, these settings are only taken into account when the database is used in remote mode. The parameters are grouped onto two tabs: Network options and IP configuration (Allow-Deny Configuration Table). This option lets you indicate whether or not the 4D Server database will appear in the list of published databases.
Note: If you modify this parameter, you must restart the server database in order for it to be taken into account. This option lets you change the publication name for a database published by 4D Server, i.e., the name displayed on the dynamic TCP/IP publication page of the connection dialog box (see the Connecting to a 4D Server Database section). Note: This parameter is not taken into account in custom client-server applications. In theory, the client application connects directly to the server application, without passing by the connection dialog box. However, in the event of an error, this dialog box will appear; in this case, the publication name of the server application is the name of the compiled database. This option lets you change the TCP port number on which 4D Server publishes the database. This information is stored in the structure of the database and on each client machine. By default, the TCP port number used by 4D Server and 4D in remote mode is 19813. Note: Only databases published on the same port as the one set in 4D client are visible on the TCP/IP dynamic publication page. 4D Server uses three TCP ports for communications between internal servers and clients:
This thermometer is used to set the timeout (period of inactivity beyond which the connection is closed) between 4D Server and the client machines connecting to it. When this option is checked, all the 4D remote machines connecting to the database can execute methods remotely. This mechanism is detailed in the section Stored procedures on client machines. This option lets you activate the SSL mode (secured mode) for communications between the server machine and the 4D remote machines. This option is detailed in the Encrypting Client/Server Connections section. This setting can be used to globally set the updating mode for the local instance of the Resources folder on the connected 4D machines when the Resources Resources folder of the database is modified during the session (the Resources folder is automatically synchronized on the remote machine each time a session is opened). Three settings are available:
This option sets the opening mode for the database structure on client machines. By default, the Read/Write mode is set but you can also set it to Read only in order to prevent the structure from being modified. |
