          Steps for getting an ODBC connection to the YourDbName database on a local machine:


          Get an Oracle client on your machine:

          - First, go to the Oracle instant client download page (http://www.oracle.com/technetwork/topics/winsoft-085727.html) and download the ‘Instant Client Package – Basic’ – it’s the first one.

          - Extract the contents of the downloaded zip file to C:\Oracle

          Create a TNS names file:

          - Copy the following text into a blank text file:


          TNS Name=

            (DESCRIPTION =

              (ADDRESS_LIST =

                (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1800))


              (CONNECT_DATA =

                (SERVICE_NAME = )




          - Save this text file into the C:/Oracle/network/admin folder (create it if it doesn’t exist already), and name it tnsnames.ora (if you have a tnsnames.ora file already, add the copied text to the end of it.

          - Go to ‘My Computer’ -> Properties -> Advanced -> Environment Variables, and under ‘User variables’, add a new variable with name TNS_ADMIN, and value ‘C:/Oracle/network/admin’ (or wherever your tnsnames.ora file is)


          Create an ODBC Data Source:

             - Go to Control Panel -> Data Sources (ODBC) -> System DSN, and click Add..

             - Scroll to the bottom of the list and select ‘Oracle in instantclient_11_2’

                      - Create a data source
