Subject DERBY_INSTALL and DERBY_HOME
Date Thu, 15 Jun 2006 21:07:53 GMT
1) In Working With Derby, "Activity 1: Run SQL using the Embedded driver", is written:

"The DERBY_HOME variable defines the filesystem path to the root directory of the Derby
installation."

set DERBY_HOME=C:\derby

2) In Derby Developer's Guide, "The installation directory", is written:

"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

3) In Getting Started with Derby, "Set the DERBY_INSTALL environment variable", is written:

"During installation, a base directory was created where the software was installed. This
document
assumes that directory is named Derby_10. This document refers to that directory as the Derby
base
directory."

set DERBY_INSTALL=c:\Derby_10

4) Conclusion:

There are two environment variables for the root directory of the Derby installation
(DERBY_INSTALL and DERBY_HOME), three directories (C:\derby, C:\DERBY_INSTALL and c:\Derby_10),
and two definitions ("filesystem path to the root directory of the Derby installation" and
"Derby
base directory").

In my opinion, for the users' benefit, it would be good to have only one environment variable,
with only one value, and only one definition.
