How to start with a fresh / clean database for Bahmni?

How to specify my database in installation configuration?

Any clue how to do this for a Vagrant box install?

If you are using v0.93 vagrant, you can drop the DB in the vagrant, and restore a Fresh DB of OpenMRS from here: bahmni-package/bahmni-emr/resources at master ยท Bahmni/bahmni-package ยท GitHub (file: openmrs_clean_dump.sql)

For OpenELIS clean DB is here: bahmni-package/configureDB.sh at master ยท Bahmni/bahmni-package ยท GitHub

For Odoo clean DB is here: bahmni-package/bahmni-erp/resources at master ยท Bahmni/bahmni-package ยท GitHub

Since all 3 DBs are interconnected, you would need to refresh them all together. If things go in some wonky state, you can always destroy your vagrant box, and bring it up again, and it should be back up with the orginal vagrant pre-loaded db.
