Connecting to Microsoft Access with Unicode

Type 2 driver. Use the settings in the following table to connect ColdFusion MX to Microsoft

Access with Unicode data sources:

Setting Description

CF Data Source Name The data source name (DSN) used by ColdFusion MX to connect to the

data source.

Database File The file that contains the database.

Description (Optional) A description for this connection.

ColdFusion Username The user name that ColdFusion MX 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.

ColdFusion Password The password (16-character limit) that ColdFusion MX 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 MX 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.

Limit Connections Specifies whether ColdFusion MX limits the number of database

connections for the data source. If you enable this option, use the Restrict

Connections to field to specify the maximum.

Restrict Connections to Specifies the maximum number of database connections for the data

source. To use this restriction, you must enable Limit Connections.

Maintain Connections ColdFusion MX 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 MX 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 (min) The time (in minutes) that the server waits between cycles to check for

expired data source connections to close.

Disable Connections If selected, suspends all client connections.

connection login attempt.

CLOB Select to return the entire contents of any CLOB/Text columns in the

database for this data source. If not selected, ColdFusion MX retrieves

the amount specified in the Long Text Buffer setting.
