Connecting to DB2 Universal Database 6.2, 7.2 Use the settings in the following table to connect ColdFusion to DB2 Universal Database 6.2, 7.2 data sources: Setting Description CF Data Source Name The data source name (DSN) used by ColdFusion to connect to the data source. Database The name of the database. Server The name of the server that hosts the database that you want to use. 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. Username 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. 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 maximum number of minutes after the data source connection is made that you want ColdFusion to cache a connection after it is used. Interval (sec) The time (in seconds) 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 unchecked, ColdFusion retrieves the amount 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 unchecked, ColdFusion retrieves the amount specified in the Blob Buffer setting. LongText Buffer (chr) The default buffer size, used if Enable Long Text Retrieval(CLOB) is not selected. Default is 65000 bytes. BLOB Buffer (bytes) The default buffer size, used if Enable binary large object retrieval (BLOB) is not selected. Default is 65000 bytes. Allowed SQL The SQL operations that can interact with the current data source. Connecting to DB2 Universal Database 6.2, 7.2 37

Connecting to DB2 Universal Database 6.2, 7.2
Use the settings in the following table to connect ColdFusion to DB2 Universal Database
6.2, 7.2 data sources:
Setting
Description
CF Data Source
Name
The data source name (DSN) used by ColdFusion to connect to the
data source.
Database
The name of the database.
Server
The name of the server that hosts the database that you want to use.
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.
Username
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.
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 maximum number of minutes after the data source connection
is made that you want ColdFusion to cache a connection after it is
used.
Interval (sec)
The time (in seconds) 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 unchecked, ColdFusion
retrieves the amount 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 unchecked, ColdFusion
retrieves the amount specified in the Blob Buffer setting.
LongText Buffer (chr)
The default buffer size, used if Enable Long Text Retrieval(CLOB) is
not selected. Default is 65000 bytes.
BLOB Buffer (bytes)
The default buffer size, used if Enable binary large object retrieval
(BLOB) is not selected. Default is 65000 bytes.
Allowed SQL
The SQL operations that can interact with the current data source.
