MAC OS X

Suppose you have a 4D Server running on a custom port (19810) instead of the default port 19813. If you want to mirror this server, you must also customize the port number for 4D BACKUP to match this server.


  1. Do a find for "TCP.OPT".
    NOTE: this file will only be created after you have made at least one connection.

  2. Launch 4D Customizer plus and open the TCP.OPT file.

  3. Double click "Preferences".

  4. Change the port number to the value you want to use.

  5. Close the window and the file.

  6. When prompted to save, click the save button.



4D SERVER
You want to place the customized TCP.OPT file next to 4D Server. On windows, you can simply place the TCP.OPT file next to 4D Server.exe. On MAC OS X, you must open the package. CONTROL+CLICK on the application and select "Show Package Contents." Go into "Contents" and then MacOSClassic.

MIRROR MACHINE
The location of the TCP.OPT file depends on your OS.
MAC OS X - Place the TCP.OPT file next to your database structure
WIN XP - Place the TCP.OPT file next to the backup application. (4DBackup.exe)
