54 Chapter 3: Data Source Management
Select Method Determines whether server cursors are used for SQL queries.
• The Direct method provides more efficient retrieval of data when you retrieve
record sets in a forward-only direction and you limit your SQL Server
connection to a single open SQL statement at a time. This is typical for
ColdFusion applications.
• The Cursor method lets you have multiple open SQL statements on a
connection. This is not typical for ColdFusion applications, unless you use
pooled statements.
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 the Limit Connections option.
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.
String Format Enable this option if your application uses Unicode data in DBMS-specific
Unicode datatypes, such as National Character or nchar.
Max Pooled
Statements
Enables reuse of 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:
• Unique
cfquery tags that use the cfqueryparam tag
• Unique
cfstoredproc tags
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 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 number of
characters 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 number of
characters specified in the BLOB Buffer setting.
LongText Buffer The default buffer size, used if Enable Long Text Retrieval(CLOB) is not
selected. The default value is
64000 bytes.
BLOB Buffer 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.
