The installation directory

The installation program installs the Derby software in a directory of your choice. See the install.html file for information on how to install Derby.

The installer automatically creates setup scripts that include an environment variable called DERBY_INSTALL. The installer's value is set to the Derby base directory.

C:>echo %DERBY_INSTALL%
C:\DERBY_INSTALL

If you want to set your own environment, Getting Started with Derby instructs you on setting its value to the directory in which you installed the Derby software.

The installer for Derby installs all the files you need, including the documentation set, some example applications, and a sample database.
