 1. In the main menu select 'Windows'
 1. Select Preferences
 1. Select Java
 1. Select Installed JRE's

== Can/should I use Infobright / Brigthouse for big data ==
The Infobright open source version can only be populated using their own data loader. It doesn't support INSERT, UPDATE, DELETE so in practice it is useless for anything else than one-off data warehousing. Then you need to pay top dollar.

Use the following bat script in windows

{{{
for /f "tokens=* delims=" %%i in ('dir /s /b /a:d *svn') do (
rd /s /q "%%i"
)
