The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Connecting to Oracle without connecting to any client tools

Asked by rkneal in Databases Miscellaneous

Tags: , ,

I know this has probably been asked before, but is it possible to have a program that connects and retrieves data from Oracle without having to load any Oracle Client tools, dll's, etc.  We have about 5000 PC's that i need to push this program to that when the user logs in, it connects to oracle, gathers info, then disconnects.  I definitely cannot load anything else than this one executable, so loading oracle client tools out of question.   Is this possible to do this without loading anything else on machine?  

I have tried the following but keep getting the error at bottom of page  (using vb.net)

Imports System.Data.Odbc

Module Module1
    Public Function testoracleFunction()

        Dim oODBCConnection As Odbc.OdbcConnection
       
        Dim sConnString As String = _
            "Driver={Microsoft ODBC for Oracle};" & _
            "Server=myserverDNSname;" & _
            "Uid=myuser;" & _
            "Pwd=mypassword"
        oODBCConnection = New Odbc.OdbcConnection(sConnString)
       
'connection info from tnsnames just for info only
        'string oradb = "Data Source=(DESCRIPTION="                  
        '            + "(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=myserverDNSName)(PORT=1621)))"
        '           + "(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=xxx)));"
        '          + "User Id=myuser;Password=mypassword;";

        Try

            oODBCConnection.Open()

        Catch ex As Exception
            Console.WriteLine(ex.Message)
        End Try

    End Function

End Module


error message
[Microsoft][ODBC Driver Manager] The driver doesn't support the version of ODBC behavior that the application requested (see SQLSetEnvAttr).
