Description

(Optional) A description for this connection.

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.

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.

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.
