Drop and Prime Database

On the linux shell, run the below.

mongo

use opaddress

db.dropDatabase()

exit

/usr/local/omk/bin/opaddress-cli.pl act=setup-db

And that should be all you need to do. As long as the database exists, opAddress will prime it with any required data.

Example console output doing that is below (with added show dbs to show the registered databases along with their sizes).
