Can't get vbscrip to connect to Oracle Database

Question

Hi,
I really need some help please as I’m new to vbscripting and TNS connections and all this complicated stuff.
I’m trying to make a connection from one of our Oracle servers and extract some basic data but after trying for a couple of days I’m stumped.
Here’s the details and I hope someone can advise me in a simple language on where I’m going wrong.
The server I am trying to connect from is an Essbase server which already has an ODBC connection to the Oracle server setup in the ODBC Datasource Administrator. The driver that I can see in the ODBC Datasource Administrator is ‘Oracle in OraClient10g_home1’ and a ‘SQL Sever’ driver along with some MEARNT OEM drivers.
The tnsnames.ora has the information for the Oracle server and I can tnsping to it successfully.
Browsing round the web I have tried a couple of methods to connect:
*"Driver={Microsoft ODBC for Oracle};Dbq=ABCD;Uid=LOGIN;Pwd=PASSWORD;"*
I get the error message:
'Provider is not specified and there is no designated default Provider.'
I understand that I don’t have the Microsoft ODBC for Oracle driver installed, not sure if we need it if we have the Oracle in OraClient10g_home1 driver and already have a connection set up. So I tried:
*"Driver={ Oracle in OraClient10g_home1 };Dbq=ABCD;Uid=LOGIN;Pwd=PASSWORD;"*
Again.. +'Provider is not specified and there is no designated default Provider.'+
I also tried another method suggested:
Dim strCon
*strCon = "Driver={Oracle in OraClient10g_home1}; " & _*
*         "CONNECTSTRING=(DESCRIPTION=" & _*
*         "(ADDRESS=(PROTOCOL=TCP)" & _*
*         "(HOST=EssbaseServer)(PORT=1592))" & _*
*         "(CONNECT_DATA=(SERVICE_NAME=ABCD))); uid=LOGIN;pwd=PASSWORD;"*
*Dim oCon: Set oCon = WScript.CreateObject("ADODB.Connection")*
*Dim oRs:  Set oRs  = WScript.CreateObject("ADODB.Recordset")*
*oCon.Open strCon*
*oCon.Close*
*Set oRs = Nothing*
*Set oCon = Nothing*
Same error message again:
+Provider is not specified and there is no designated default Provider.+
This leads me to believe that maybe I need to have the Microsoft ODBC for Oracle drivers installed on the server. Maybe I need to set my script differently and am totally doing it wrong. Any help please? If you think I need the driver could you please explain why and how it works so I can put forward for my arguement to install it on the server.
Many thanks

<p>By the error message that you are receiving it sounds like the report was originally designed to use an ODBC or native connection. The JRC will automatically attempt to look for a JNDI name of the same data source when it encounters one of these types of data sources.</p><p>If this is the case then you cannot use the viewer object to pass in the ConnectionInfos. The viewer object can only be used to login to the same data source, not change the location.</p><p>What you need to do is follow the code snippet included in the following sample:</p><p><a href="/files/jrc_change_database_connection_0.zip">http://diamond.businessobjects.com/files/jrc_change_database_connection_0.zip</a></p><p>That should help you out. <br /></p><p>Regards,<br />Sean Johnson (CR4E Product Manager) <br /><br /> <a href="http://www.eclipseplugincentral.com/Web_Links-index-req-ratelink-lid-639.html">Rate this plugin @ Eclipse Plugin Central</a>          </p>
