Use the settings in the following table to connect ColdFusion to Apache Derby Client data sources. For information on support for specific versions, see www.adobe.com/go/sysreqscf.
Option |
Description |
CF Data Source Name |
The data source name (DSN) that ColdFusion uses to connect to the data source. |
Database |
The name of the database. |
Server |
The fully qualified domain name or IP address of the server that hosts. 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 that you set up using the Client Connectivity Wizard. |
Port |
The port number of the server. |
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. |
Limit Connections |
If selected, limits the number of data source connections to the value entered in the Restrict Connections To field. |
Maintain Connections |
ColdFusion establishes a connection to a data source for every operation that requires one. Select this option to improve performance by caching the data source connection. |
Interval (min) |
The time (in minutes) that the server waits between cycles to check for expired data source connections to close. |
Timeout (min) |
The number of minutes that ColdFusion maintains an unused connection before destroying it. |
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 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 not selected, ColdFusion retrieves the amount specified in the BLOB Buffer setting. |
Long Text Buffer (chr) |
The default buffer size, used if the CLOB option is not selected. The default value is 64000 bytes. |
BLOB Buffer (bytes) |
The default buffer size, used if the BLOB option is not selected. The default value is 64000 bytes. |
Disable Autogenerated Keys |
Disables the autogeneration of keys for data sources |
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. You should specify this just before restarting the database to verify all connections, but remove the validation query after restarting the database to avoid any performance loss. |
