Embedded H2 Database
To enable you to try Confluence without setting up an external database, your Confluence installation includes an embedded H2 database.
The embedded H2 database is used by default when you choose the Trial installation path.
The embedded database files are stored in your Confluence home directory <confluence-home>/database.
The embedded H2 database is only supported while you are evaluating Confluence. You must migrate to a supported external database before using Confluence as a production system.
To find out if you are still using the embedded database, go to 
> General Configuration > Support Tools.
Connect to the embedded H2 database using DB Visualizer
DBVisualizer is just one database administration tool. You can use any administration tool that supports embedded H2 databases. The steps will be similar.
- Shut down Confluence.
- Back up your
<confluence-home>/databasedirectory. - Launch DBVisualizer.
- Choose Create new database connection and follow the prompts to set up the connection.
The information you'll need is:- Database driver: H2 embedded
- Database Userid: sa
- Database password: leave this field blank
- Database filename:
<confluence-home>/database/h2db
leave off the .h2.dbfile extension.
- Connect to the database.
Refer to the DBVisualizer documentation for help using DBVisualizer.
Connect to the embedded H2 database using the H2 console
Alternatively you can connect using the browser based H2 console. The easiest way to access the console is to double click the H2 database jar file at <installation-directory>\confluence\WEB-INF\lib\h2-x.x.x.jar.
