Data Source Management
Setting Description
User name 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
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
Description (Optional) A description for this connection.
Connection String A field that passes database-specific parameters, such as login credentials, to the data source.
Limit Connections Specifies whether ColdFusion 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, enable the
Limit Connections option.
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.
Max Pooled Statements Enables reuse of prepared statements (that is, stored procedures and queries that use the
Although you tune this setting based on your application, start by setting it to the sum of the following:

Timeout (min) The number of minutes that ColdFusion MX maintains an unused connection before destroying it.
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 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,

BLOB Buffer The default buffer size; used if the BLOB option is not selected. The default value is
Allowed SQL The SQL operations that can interact with the current data source.
Validation query Called when a connection from the pool is resued. This can slow query response time because an additional query
is generated. Configure the validation query just before restarting the database to verify all connections, but
remove the validation query after restarting the database to avoid any performance loss.
Client Hostname The host name from where the query is executed.
Client Username The user name if the user is logged in using the <cflogin> tag.
Application Name The application name specified in the application.cfc.
Prefix If specified, the value is prefixed with the application name specified in application.cfc.
