CF Data Source Name
|
The data source name (DSN) that ColdFusion
uses to connect to the data source.
|
Database
|
The database to which this data source connects.
|
Informix Server
|
The name of the Informix database server
to which you want to connect.
|
Server
|
The name of the server that hosts the database.
If the database is local, enclose the word local in parentheses.
|
Port
|
The number of the TCP/IP port that the server
monitors for connections.
|
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 cfquery tag).
|
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 cfquery tag).
|
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 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.
|
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, ColdFusion 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 retrieves the number of characters specified
in the BLOB Buffer setting.
|
LongText Buffer
|
The default buffer size, used if the CLOB
option 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.
|
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.
