mysqldump unknown database bitnami_redmine

I'm currently trying to migrate the mysql database from the Bitnami Redmine stack on a Windows machine to Ubuntu.

When I try to mysqldump the database following happens:

C:\BitNami\redmine-2.3.1-1\mysql\bin>mysqldump -u root -p bitnami_redmine > backup_redmine.sql Enter password: ************ mysqldump: Got error: 1049: Unknown database 'bitnami_redmine' when selecting the database

mysqlshow give following output:

C:\BitNami\redmine-2.3.1-1\mysql\bin>mysqlshow -u root -p
Enter password: ************

Can someone tell me why bitnami_redmine database isn't shown under mysql databases?

Thanks a lot,
