7.3. Virtuoso Driver for ODBC

7.3.1. Windows ODBC Driver Configuration

At installation time two ODBC data source names (DSN's) are created with default values by the Virtuoso installer, the first DSN named "Local Virtuoso" provides a link to a local default Virtuoso database server instance, while the other named "Local Virtuoso Demo" provides a link to a local Virtuoso server for the Virtuoso demonstration database.

The process of creating additional ODBC DSN's for you Virtuoso drivers for ODBC is explained in the steps that follow:

  1. Go to the Windows Control panel .

  2. Double click on the ODBC Administrator applet. On Windows 2000 / XP the ODBC Administrator applet may be called Data Source (ODBC) and may be found under Administrative tools icon of the Control Panel.

  3. Once the ODBC Administrator has been loaded choose by selecting the appropriate panel whether you want a new User or System Data Source. User Data Sources will only be available to the user that created them. System Data Sources will be available to all users and applications on the system.

  4. Click on the Add Data Source Name button

  5. Select the Driver named OpenLink Virtuoso Driver

  6. Enter values into the fields presented by the Virtuoso Driver's DSN configuration dialog:

    Name: provide a name that will act as a logical reference to the Virtuoso database server that you will be connecting to. Subsequent references to this database will be made to this value when ODBC compliant applications interact with your Virtuoso driver.

    Description: allows you to provide a short description about the nature of the connection. This is optional.

    Server: enter the hostname or IP address of the machine hosting your Virtuoso server and enter the port number that Virtuoso is listening at. This is configured in the Virtuoso ini file on the server.
