The doc says as follows,
1)Take a back up copy of odbc.ini (and/or odbc64.ini) files in the .../instances/instance1/bifoundation/OracleBIApplication/coreapplication/setup directory.
2) Check for a duplicate option "Driver" or a syntax error and correct it by hand. This should enable 'commit' to proceed correctly.
But I didn't find any duplicate in that file to change. Can you please suggest me what need to be changed.
Can any one help me on this.
