An overview of the directory structure

LN uses a Virtual Machine (VM) to make the software independent of the operating system. LN can, therefore, run on a UNIX operating system or a Windows operating system. For this reason, the notation of the directories in this chapter is subject to your operating system: UNIX operating systems use slashes (/) and Windows uses back slashes (\). For example, the directory notation on a UNIX system is ${BSE}/application/… and on a Windows operating system the notation for the same directory is ${BSE}\application\….

Note: Unless otherwise noted, the directories that are described are used in both operating systems.

The LN application is stored in the ${BSE} directory. The main subdirectories in the ${BSE} are:

The subdirectories that contain the software.
The dict subdirectory, which contains the subdirectories for the table and domain definitions of all packages and package combinations except for Enterprise Server.
The test subdirectory, which contains the test data and demonstration data, and dumps for the applications.

This diagram shows LN’s main directories:

The location of the software environment on your operating system is defined by the LN software ${BSE} environment variable. You must define the ${BSE} variable for each LN user.
