A Data Source is a named object that contains criteria that ODBC requires to connect to the Archive ODBC driver and locate an Archive File.
To create a Data Source for accessing an Archive File, open the Microsoft ODBC Data Source Administrator dialog. The method you use to open this dialog varies according to the version of Windows on your workstation. For Windows 2000, click .
Select the Drivers tab on the ODBC Data Source Administrator dialog to confirm that the Optim Archive File Driver is available.
Next, click the User DSN or System DSN tab to create a Data Source. (A User Data Source can only be used by the specific user, on the current machine; a System Data Source can be shared. Refer to Windows Help for further information on each type.)
Click Add on the selected tab to display the Create New Data Source dialog.
Select the Optim Archive File Driver and click Finish to display the ODBC Source Data Default Specification dialog.
Use the ODBC Source Data Default Specification dialog to define specifications for the ODBC Data Source.
You can enter values to select a single Archive File, or enter wildcard patterns so that a set of Archive Files are referenced. Use the % (percent) symbol to represent any number of characters, or the _ (underscore) to represent a single character. A wildcard pattern must match the naming convention appropriate for the object referenced by the value (for example, %.% for the two-part Archive File name).
The processing protocol for merging parameters in a file or passed on the ODBC connection call with those in the Data Source is: Parameter file specifications override connection call parameters, which override Data Source specifications.
Processing cannot proceed until a single Archive File is selected. If the parameters identify a single Archive File, processing proceeds. If more than one Archive File meets the criteria, you are prompted to select the Archive File to be processed. If the connection call does not permit prompting, the process terminates.
Enter specific or generic criteria on the ODBC Source Data Default Specification dialog to define a Data Source, as follows:
