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 immediately. Doing so allows the cache to warm before queries are executed against the database.
Note
The AutoStart connection parameter controls whether or not a database server is automatically started. It does not control whether a database is automatically started. Use the DatabaseName connection parameter to connect to a database that
is already started. Use the DatabaseFile connection parameter to connect to a database that is already started or to automatically
start and connect to a database if necessary.
