ColdFusion automatically verifies that it can connect to the data source.
If your database requires login information, enter your user name and password. For example, the bullwinkle server on the default port. In the Server field, enter the network name or IP address of the server that hosts the database, and enter any required Port value.In the Database field, enter the name of the database.
The available fields in this form depend on the driver that you selected. Click Add.A form for additional DSN information appears.Select a driver from the drop-down list for example, Microsoft SQL Server.The following names are reserved you cannot use them for data source names: Under Add New Data Source, enter a data source name for example, MyTestDSN.In the ColdFusion Administrator, select Data & Services > Data Sources.
You do not need the following procedure to work with these data sources. When you add a data source, you assign it a data source name (DSN) and set all information required to establish a connection.ĬoldFusion includes data sources that are configured by default. You use the ColdFusion Administrator to quickly add a data source for use in your ColdFusion applications.
ColdFusion includes Type 4 drivers for many DBMSs however, not all DBMSs are supported in ColdFusion Standard Edition.
No special software needed on the computer on which you run ColdFusion.Disadvantages: Many of these protocols are proprietary, requiring a different driver for each database. ColdFusion includes an ODBC socket Type 3 driver for use with Microsoft Access databases and ODBC data sources.Ĭonverts JDBC calls to the network protocol used directly by the database.Advantages: Fast performance. Can be tailored for small size (faster loading).Disadvantages: Database-specific code must be executed in the middle tier. Translates JDBC calls to the middle-tier server, which then translates the request to the database-specific native-connectivity interface.Advantages: The database libraries of vendors are not required client computer. ColdFusion includes a Type 2 driver for use with Microsoft Access Unicode databases. Performance is slower than other JDBC driver types.Adobe does not recommend this driver type unless your application requires DBMS-specific features.Ĭonverts JDBC calls to database-specific calls.Advantages: Better performance than Type 1 driver.Disadvantages: The client database libraries of the vendor must reside on the same computer as ColdFusion. Advantages: Allows access to many different databases.Disadvantages: The ODBC driver, and possibly the client database libraries, must reside on the ColdFusion server computer.
