Connecting to Microsoft Access with Unicode

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.

Login Timeout (sec)

The number of seconds before ColdFusion MX times out the data source 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.

BLOB

Select to return the entire contents of any BLOB/Image columns in the database for this data source. If not selected, ColdFusion MX retrieves the amount specified in the Blob Buffer setting.

LongText Buffer

The default buffer size, used if Enable Long Text Retrieval(CLOB) is not selected. Default is 64000 bytes.

BLOB Buffer

The default buffer size, used if Enable binary large object retrieval (BLOB) is not selected. Default is 64000 bytes.

Allowed SQL

The SQL operations that can interact with the current data source.
