SUMMARY
This article provides a list of valid SQLConfigDatasource settings for the Microsoft ODBC Driver for Oracle, version 1.0 (Msorcl10.dll) and the Microsoft ODBC Driver for Oracle, version 2.0 (Msorcl32.dll).

Note that the Msorcl10.dll ODBC driver (version 1.0) supports all of the settings below except the Server setting.

The Msorcl32.dll ODBC driver (version 2.0 and higher) supports all of the settings listed below.

Some of the settings are ignored by the driver but are accepted by SQLConfigDatasource. These settings can only be provided at run time by including them in the ODBC connection string. An ignored setting will not be stored in the registry when SQLConfigDatasource creates the data source. You can run the sample code provided below and examine the registry settings created to determine which settings are ignored by the particular driver you are using.

In the chart below, A/N means any valid alphanumeric string up to the maximum allowable length. Max Len (maximum length) is the maximum allowable string length accepted by the setting and includes the zero terminator character when determining the length.   Setting            Max Default  Valid    Setting Name              Len Value    Values   Description --

MORE INFORMATION
The following code sample demonstrates how to create a data source using the SQLConfigDataSource application program interface (API) functions with the two available Microsoft Oracle ODBC drivers. // START CODE SAMPLE
