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.
Disable Connections
If selected, suspends all client connections.
Login Timeout (sec)
The number of seconds before ColdFusion 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 unchecked, ColdFusion 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 unchecked, ColdFusion retrieves the amount specified in the Blob Buffer setting.
LongText Buffer (chr)
The default buffer size, used if Enable Long Text Retrieval(CLOB) is not selected. Default is 65000 bytes.
BLOB Buffer (bytes)
The default buffer size, used if Enable binary large object retrieval (BLOB) is not selected. Default is 65000 bytes.
Allowed SQL
The SQL operations that can interact with the current data source.
