The purpose of this guide is to walk you through connecting to Crowd's embedded Hypersonic SQL Database using the Database Administration tool DBVisualizer.

Below are step-by-step instructions on how to configure DBVisualizer and connect it to HSQLDB.


  1. Download and install the latest copy of DBVisualizer
  2. You will also need to download a copy (preferably the latest version) of HSQLDB
  3. Extract the contents of the HSQLDB archive
  4. Ensure that Crowd is not running

Remember to backup your <Crowd-home>/database folder before attempting any modifications
