Data Source Management

Last updated 2/21/2012

For example, you can use the Other Data Sources option to define a data source for DB2 OS/390 or iSeries, using the

following settings:

JDBC URL jdbc:datadirect:db2://dbserver:portnumber

Driver class .jdbc.Driver

Driver name DB2

User name A user defined to the database

Password The password for the user name

Setting Description

CF Data Source Name The data source name (DSN) that ColdFusion uses to connect to the data source.

JDBC URL The JDBC connection URL for this data source.

Driver Class The fully qualified class name of the driver. For example, com.inet.tds.TdsDriver. The JAR file that

contains this class must be in a directory defined in the ColdFusion classpath.

Driver Name (Optional) The name of the driver.

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.

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.

connection.

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 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.
