Setting Up an ODBC Data Source for Oracle

https://msdn.microsoft.com/en-us/library/ms709329(v=vs.85).aspx http://www.interfaceware.com/manual/odbc_oracle.html You can control performance of the ODBC Driver for Oracle by knowing the data environment and correctly setting the parameters of the data source connection through the ODBC Data Source Administrator dialog box or through connect string parameters. The dialog box provides the following controls for connecting to a data source using the dialog box or using connect strings: User DSN tab Lists the Data Source Names that are local to the computer. System DSN tab Enables you to add or remove a system data source. System data sources can be accessed by all users on the local computer. File DSN tab Enables you to add or remove a file data source from the local computer. File data sources can be shared by all users who have the same driver installed. Drivers tab Lists the installed ODBC drivers. Tracing tab Enables you to specify how the ODBC Driver Manager traces calls to ODBC functions. You can configure tracing separately for each installed ODBC application. Connection Pooling tab Enables you to select connection options for each installed driver.
