Database Flush Command not working

[william humphrey]

vServer_x61 has a folder "databases" and in that folder is stored my
database. When I am using it I assume it is ram based because it is
very fast and if the computer crashes I lose all data.

I'm looking for a command that I can run which will write the database
from ram to the file in the "database" folder so that when the
computer crashes I only lose whatever was done since that last time
that "commit to hard drive" command is run.
