# The function creates the database concatenating username  and user_db.
# Supported yypes of databases you can get using v-list-sys-config script.
# If the host isn't stated and there are few hosts configured on the server,
# then the host will be defined by one of three algorithms. "First" will choose
# the first host in the list. "Random" will chose the host by a chance.
# "Weight" will distribute new database through hosts evenly. Algorithm and
# types of supported databases is designated in the main configuration file.
