Connecting to JNDI data sources
Use the settings in the following table to connect ColdFusion MX to JNDI data sources that have
been defined for a J2EE application server (multiserver and J2EE configurations only):
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.
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.
Setting
