If you are running streama with the default setting you can manage your h2 using the built-in /dbconsole endpoint. But first, you got to enable the dbconsole for your production environment (and maybe disable it again after you've done your managing, otherwise your system might be vulnerable).

Note: only users with admin-rights can access that endpoint.

Enable dbconsole

add the following to your application.yml

environments:
  production:
    grails:  
      dbconsole:
        enabled: true

Or if you already have a block for environments: production: then add the grails-bit to it, like so:

You gotta restart your streama-server for this change to take effect.

Accessing dbconsole

Now you can navigate to //your.streama.com/dbconsole

There, make sure to input the correct jdbc connection string (default is jdbc:h2:./streama;MVCC=TRUE;LOCK_TIMEOUT=10000;DB_CLOSE_ON_EXIT=FALSE)

This should list all tables on the left and allow you to do some basic sql operations!
