Connecting to Microsoft Access Use the settings in the following table to connect ColdFusion to Microsoft Access data sources: Setting CF Data Source Name Database File System Database File Use Default Username Description Default Username Default Password Username Password Page Timeout Max Buffer Size Connection String Maintain Connections Timeout (min) Interval (sec) Description The data source name (DSN) used by ColdFusion to connect to the data source. The password required to connect to the data source. If you want to secure access to the specified database file, click Browse Server to locate and enter a database that contains database security information. The system database is usually located in winnt\system32\system.mdw. If selected, ColdFusion does not pass a user name or password when requesting a connection. The Microsfot Access driver uses the default user name and password. (Optional) A description for this connection. The user name that the driver uses to connect to the data source if an application requests a connection without supplying a username. The password that the driver uses to connect to the data source if an application requests a connection without supplying a password. The user name that ColdFusion passes to the JDBC driver to connect to the data source if a ColdFusion application does not supply a user name-for example, in a cfquery tag. The password that ColdFusion passes to the JDBC driver to connect to the data source if a ColdFusion application does not supply a password-for example, in a cfquery tag. The time (in tenths of a second) before a request for a ColdFusion page times out. The total number of bytes that ColdFusion uses to cache application pages. Enter a value to optimize ColdFusion performance. A field that passes database-specific parameters, such as login credentials, to the data source. ColdFusion establishes a connection to a data source for every operation that requires one. Enable this option to improve performance by caching the data source connection. The maximum number of minutes after the data source connection is made that you want ColdFusion to cache a connection after it is used. The Timeout setting does not return a connection to the cache after a specified period of time, regardless of how infrequently it is used. The default is "" or 0, which means that the connection timeout is never enforced. The time (in seconds) that the server waits between cycles to check for expired data source connections to close.

Connecting to Microsoft Access
Use the settings in the following table to connect ColdFusion to Microsoft Access data
sources:
Setting
Description
CF Data Source
Name
The data source name (DSN) used by ColdFusion to connect to the
data source.
Database File
The password required to connect to the data source.
System Database
File
If you want to secure access to the specified database file, click
Browse Server to locate and enter a database that contains
database security information. The system database is usually
located in winnt\system32\system.mdw.
Use Default
Username
If selected, ColdFusion does not pass a user name or password
when requesting a connection. The Microsfot Access driver uses
the default user name and password.
Description
(Optional) A description for this connection.
Default Username
The user name that the driver uses to connect to the data source if
an application requests a connection without supplying a username.
Default Password
The password that the driver uses to connect to the data source if an
application requests a connection without supplying a password.
Username
The user name that ColdFusion passes to the JDBC driver to
connect to the data source if a ColdFusion application does not
supply a user name—for example, in a
cfquery
tag.
Password
The password that ColdFusion passes to the JDBC driver to
connect to the data source if a ColdFusion application does not
supply a password—for example, in a
cfquery
tag.
Page Timeout
The time (in tenths of a second) before a request for a ColdFusion
page times out.
Max Buffer Size
The total number of bytes that ColdFusion uses to cache application
pages. Enter a value to optimize ColdFusion performance.
Connection String
A field that passes database-specific parameters, such as login
credentials, to the data source.
Maintain
Connections
ColdFusion establishes a connection to a data source for every
operation that requires one. Enable this option to improve
performance by caching the data source connection.
Timeout (min)
The maximum number of minutes after the data source connection
is made that you want ColdFusion to cache a connection after it is
used.
The Timeout setting does not return a connection to the cache after
a specified period of time, regardless of how infrequently it is used.
The default is "" or 0, which means that the connection timeout is
never enforced.
Interval (sec)
The time (in seconds) that the server waits between cycles to check
for expired data source connections to close.
