CF Data Source Name
|
The data source name (DSN) that ColdFusion
uses to connect to the data source.
|
Database folder
|
The folder where the database is located.
|
Create Database
|
Select this option to create a database.
The new database exists in the path specified in the Database Folder.
If the database exists, an SQL warning is generated, and a connection
to the existing database is established.
|
Description
|
(Optional) A description for this connection.
|
ColdFusion user name
|
The user name you use to log in to the ColdFusion
Administrator.
|
ColdFusion Password
|
The password you use to log in to the ColdFusion
Administrator.
|
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.
|
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
|
Select this option to reuse prepared statements
(that is, stored procedures and queries that use the cfqueryparam tag).
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.
|
Disable Connections
|
If selected, suspends all client connections.
|
Login Timeout (sec)
|
The number of seconds before ColdFusion
times out the attempt to log in to the data source connection.
|
CLOB
|
Returns the entire contents of any CLOB/
Text columns in the database for this data source. If deselected,
ColdFusion retrieves the number of characters specified in the Long
Text Buffer setting. For UDB 7.1 and 7.2, a 32K limit on CLOBs exits.
|
BLOB
|
Returns the entire contents of any BLOB/Image
columns in the database for this data source. If deselected, ColdFusion
retrieves the number of characters specified in the BLOB Buffer
setting. BLOBs are not supported on UDB 7.1 and 7.2.
|
LongText Buffer (chr)
|
The default buffer size, used if the CLOB
option is not selected. The default value is 64000 bytes.
|
BLOB Buffer (bytes)
|
The default buffer size, used if the BLOB
option is not selected. The default value is 64000 bytes.
|
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.Specify 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.
