Connecting to ODBC Socket 57
Connecting to ODBC Socket
Use the settings in the following table to connect ColdFusion MX to ODBC Socket data sources
(this is a Type 3 driver):
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.
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.
Setting Description
CF Data Source Name The data source name (DSN) used by ColdFusion MX to connect to the
data source.
ODBC DSN Select the ODBC DSN to which you want ColdFusion MX to connect.
Trusted Connection Specifies whether to use domain user account access to the database.
Only valid for SQL Server.
Username The user name that ColdFusion MX 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).
