Part 3: The 32-Bit Drivers : The XML Driver : Configuring and Connecting to Data Sources

Configuring and Connecting to Data Sources
After you install the driver, you configure data sources to connect to the database. See Quick Start Connect for an explanation of different types of data sources. The data source contains connection options that allow you to tune the driver for specific performance. If you want to use a data source but need to change some of its values, you can either modify the data source or override its values at connection time through a connection string.
If you choose to use a connection string, you must use specific connection string attributes. See Using a Connection String and Connection Option Descriptions and Configuring and Connecting to Data Sources for an alphabetical list of driver connection string attributes and their initial default values.
On Windows, data sources are stored in the Windows Registry. You can configure and modify data sources through the ODBC Administrator using a driver Setup dialog box.
When the driver is first installed, the values of its connection options are set by default. These values appear on the driver Setup dialog box tabs when you create a new data source. You can change these default values by modifying the data source. In the following procedure, the description of each tab is followed by a table that lists the connection options for that tab and their initial default values. This table links you to a complete description of the options and their connection string attribute equivalents. The connection string attributes are used to override the default values of the data source if you want to change these values at connection time.
To configure an XML data source:
1.
User DSN: If you are configuring an existing user data source, select the data source name on the User DSN tab and click Configure to display the driver Setup dialog box.
If you are configuring a new user data source, click Add on the User DSN tab to display a list of installed drivers. Select the driver and click Finish to display the driver Setup dialog box.
System DSN: To configure a new system data source, click Add on the System DSN tab to display a list of installed drivers. Select the driver and click Finish to display the driver Setup dialog box.
File DSN: If you are configuring an existing file data source, select the data source name on the File DSN tab and click Configure to display the driver Setup dialog box.
If you are configuring a new file data source, click Add on the File DSN tab to display a list of installed drivers. Select the driver and click Next. Specify a name for the data source and click Next. Verify the data source information; then, click Finish to display the driver Setup dialog box.
The General tab of the Setup dialog box appears by default.

The General tab displays only fields that are required for creating a data source. The fields on all other tabs are optional, unless noted otherwise.

If you want to define a location, click Add. The Configure Location dialog box appears.

5.
Location: Either type the full path to the location you are defining or click the select button: to select a path.
6.
Optionally, click the Advanced tab of the Configure Location dialog box to specify additional information about the location you are defining.

On this tab, provide any of the following optional information; then, click Apply.
7.
You can click Test Connect to attempt to connect to the location.
8.
Click OK to return to the ODBC XML driver Setup dialog box or Cancel. If you click OK, the values you have specified become the defaults for this location.
9.
Optionally, click the Advanced tab of the ODBC XML driver Setup dialog box to specify data source settings.

On this tab, provide any of the following optional information; then, click Apply.
10.
Optionally, click the Options tab to specify data source connection values.

Driver Options: Type configuration options specific to the XML driver.
The properties you set in the Options tab override other properties for this session only and can adversely affect the operation of the XML driver. Use only authorized entries. For information about authorized entries for the Options tab, contact Progress DataDirect customer support.
11.
At any point during the configuration process, you can click Test Connect to attempt to connect to the data source using the connection options specified in the driver Setup dialog box. A logon dialog box appears (see Using a Logon Dialog Box for details). Note that the information you enter in the logon dialog box during a test connect is not saved.
12.
Click OK or Cancel. If you click OK, the values you have specified become the defaults when you connect to the data source. You can change these defaults by using this procedure to reconfigure your data source. You can override these defaults by connecting to the data source using a connection string with alternate values.
