CONFIGURING AND ADMINISTERING COLDFUSION 9
Data Source Management
Last updated 2/21/2012
Connecting to Sybase
To see a list of Sybase versions that ColdFusion supports, go to www.adobe.com/go/learn_cfu_cfsysreqs_en. Use the
settings in the following table to connect ColdFusion to Sybase data sources:
Disable Connections If selected, suspends all client connections.
Login Timeout (sec) The number of seconds before ColdFusion times out the attempt to log in to the data source
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.
Validation query Called when a connection from the pool is resued. This can slow query response time because an
additional query is generated. Specify the validation query before restarting the database to verify all
connections, but remove the validation query after restarting the database to avoid any performance
loss.
Setting Description
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.
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. This name must be either a fully qualified domain name (resolvable through
DNS) or an IP address. It cannot be a netbios name (even if you are running NBT), or an alias you set up
using the client connectivity wizard (both of these approaches worked in earlier ColdFusion versions).
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.
Select Method Determines whether server cursors are used for SQL queries.
The Direct method provides more efficient retrieval of data when you retrieve recordsets in a forward-
only direction and you limit your Sybase connection to a single open SQL statement at a time. This is
typical for ColdFusion applications.
The Cursor method lets you have multiple open SQL statements on a connection. This is not typical
for ColdFusion applications, unless you use pooled statements.
