By default, if no database server is found during a connection attempt, and a database file, database name, or the START connection
parameter is specified, then a personal database server is started on the same computer. You can turn this behavior off by
setting the AutoStart (ASTART) connection parameter to NO in the connection string. The database server is not started automatically
if the Host connection parameter is specified or the CommLinks (LINKS) parameter includes TCPIP.
To improve query performance for databases that are started automatically, start the database as soon as possible, even if
users are not connecting right away. This starting allows the cache to warm before queries are executed against the database.
See Cache warming.
The AutoStart connection parameter controls whether or not a server is automatically started. It does not, however, determine
whether or not a database is automatically started. To prevent a database from automatically starting, use the DatabaseName
connection parameter rather than the DatabaseFile connection parameter. See DatabaseName (DBN) connection parameter.
