What's wrong with MSDAORA.1 (Microsoft OLE DB Provider for Oracle) in SQL2008R2

Dear Gurus, I'd install a test SQL2008R2 on Windows Server 2008 R2 x64 Version. And Install Oracle both x86 and x64 version Client. And I'd create a new AS Database as AS System Administrator. And then create a new Datasource with "Microsoft OLE DB Prodiver for Oracle" Provider. When I test connection ,  it tested succeed. Then I create Datasource View / Dimension / Cubes etc... But when I process then Database. There is a error occurs. "Database Access Module Error , Provider 'MSDAORA.1' not register" I'd follow http://msdn.microsoft.com/en-us/library/ms152516.aspx change SQL Server 2008 R2's registry key as the note. Then restart this server . But still same error !   And I'd success process the cube if I change provider as "Oracle OLE DB Proverder"   Is MSDAORA been obsolete in SQL SERVER 2008 R2 ?Wilson

problem with MSDAORA provider on 64 bit environment

Hi All, I have Asp.net application which I have created on the vista 32 using vs 2005. Which uses MSDAORA provider to connect to oracle,which works fine. But when we are deploying on windows 2003 server 64bit it is giving the below error: Exception: System.InvalidOperationException: The 'MSDAORA.1' provider is not registered on the local machine. I have search on the google for the solution and found that: 'switch the appication to 32 bit and use a 32 bit Oracle client' How can I do that ? or another solution is : use a 64 bit client and oledb provider instead (Ie, Oracle's provider - ORAOLEDB.ORACLE) My question is if I installed this provider do I have to uninstall anything or just to install the oracle driver and use ORAOLEDB.ORACLE and it will work. Any suggestion very much appriciated. ThanksYanku

Errors in the back-end database access module. The managed provider 'Oracle.DataAccess.Client' cou

Hi. I have connected my SSAS in SQL server 2008 to an Oracle database.  I have installed the Oracle ODAC to enable me to set up the Data Source, the Data Source View and the Cube.  Now everything was going fine.  I could connect to the Oracle Database and I could see my tables and pull them into the DSV. But.  When I come to process the Cube it throws these errors.  Why all of a sudden do the connection objects stop working? Errors in the back-end database access module. The managed provider 'Oracle.DataAccess.Client' could not be instantiated. Errors in the high-level relational engine. A connection could not be made to the data source with the DataSourceID of 'DBIBGEORAclients', Name of 'DBIBGEORAclients'. Can anyone help here please? Thanks, David.

SSAS 2008R2 - Enable to process a database using Oracle OraOLEDB data provider



I've created a data source in BIDS using provider OraOLEDB.Oracle.1. The Oracle database is 10gR2. The client installed on my computer is 10gR2. The connexion is OK when I use Test Connexion in BIDS.

In the data source view I created a very simple query: select * from user_objects. All is fine, the fields are correctly defined.

I've created a dimension based on this query with object_id as the key.

I've deployed the solution to the server. All is working fine for the moment.

But when I process the dimension I get a dozen of error messages like (sorry error messages are in french) :

"Erreur OLE DB : Erreur OLE DB ou ODBC : Syntax error near 'OraOLEDB.Oracle.1' on line 8; 42000."

Erreurs dans le moteur de stockage OLAP : Une erreur s'est produite lors du traitement de dimension portant l'ID 'Test' et le nom 'Test'.

Problems Connecting Excel Services to Oracle Database


I am just beginning to experiment with using Excel Services with BI Dashboards in SharePoint 2010.  I created a Excel Workbook that has a data connection using connection type of OLE DB Query with a connection string of "Provider=MSDAORA.1;User ID=<username>;Data Source=<oracleEnvironment>".  I have the Excel Services Authentication Settings set up for a specific SSS ID <mySSSID>.


This Excel Workbook has been Saved to SharePoint with an entire sheet published.  The Excel Web App is displaying the sheet and the Slicers are functioning just like they do in the Excel client.  When I refresh the data on the client I get prompted for a password and it works fine.  When I refresh on the Web App I have received a variety of errors depending on what I try but nothing has helped me track down what I have missed.

Oracle connection fail with Microsoft OLEDB provider for Oracle MSDAORA.1



On my dev server I have working ssis packages that use connections Microsoft OLEDB provider for Oracle MSDAORA.1 and Oracle provider for oledb and OracleClient data provider.

I use one or the other according to my needs.

problem in connecting .net 2010 to oracle 10g via ODAC 11


hello everyone!!
i m trying to use ODAC 11 with vs2010 and oracle 10G. After installation i am able to connect the vs2010's server explorer with oracle 10G using ODAC. the thing is when i try to drag the table directly on windows application or web form, it does nothing. there is no way possible to connect any application to the database. i strongly feel that my installation is incomplete. I changes the parameters in tnsname.ora. the only thing i left in installation is executing some sql scripts after installation that are present in "C:\app\dellid\product\11.2.0\client_1\ASP.NET\SQL" folder.
Plz help

ERROR [HY000] [Informix .NET provider][Informix]Database locale information mismatch


Hi, there is an upgrade to my infimacs server and my web application encounter this error after the infimacs is upgraded.

Below is the information on the server before/after the upgrade.

Before            After

---------       -----------  

Solaris 8      Solaris 10

IDS 9.40     IDS 11.50

The web server where the web application hosted is running IBM Informix Connect 2.81. There is no such error before the upgrade is done.

As a developer, i have IBM Informix Client-SDK 2.90 installed on my local pc and debug the page where the read is needed from infimacs but no such error found.

The error come out only when it is hosted on the web server where IBM Informix Connect 2.81 is installed.

I have gone through many articles and it suggest me to set the environement  variable in the server :  DB_LOCALE=en_us.819.

I haven't try this solution but i think that this might not be the best solution.

Is it possible to to to have this settin

access Oracle database

Trying to run a stored procedure from vb code with oracle data provider.



Here is my SP:

create or replace
 Open p_getuserssignon_recordset1 for
 SELECT Distinct(Userid), UserPassword, SecurityLevel, ActiveStatus
WHERE substr(UserId,1,2) <> vUid
Order By UserId;

I would like to run this SP from code and fill a gridview with the result. 

I am not sure how to go about this, as I have found several different examples, other than the one I  think I need.

I am using the oracle data provider and I have an input parameter (vUid, which will equal "zz").

First question. When filling a gridview with a result set from a stored procedure should the recordset OUT be defined as a REFCURSOR (like i did above)? 


Do you have example code as to how to execute the SP and fill a gridview?  I keep trying different variations of code i've found on the internet without any success other than getting more confused.

(I am using VS 2005, VB).

Thank you.



Connecting to Oracle on 64bit OS

We have a 64-bit implementation of MOSS 2007. I recently installed the SharePoint SDK to use the Application Definition Designer to connect to Oracle. I enter the connection string and then I get this:

Attempt to load Oracle client libraries threw BadImageFormatException. The problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed.

I have verified that the server contains the 64 bit version of the Oracle client installed both with the instantclient and with system.data.oracleclient.dll. The only thing I can think of is that the tool was compiled as a 32bit application.  Is there a 64bit version available? Is there something else that I'm missing?

WSS 3.0 - problem with moving the database


My company wants to move a database included with WSS 3.0 installation to a *separate* server.
We want to have the database completely separated, on a different computer, on SQL Server 2005 installation.

Unfortunately, I'm not sure If the sharepoint is configured as a "Web Front End" or  "Stand-alone".
All I know, everything currently is on the same computer, and we can connect to the live database using the following path: \\.\pipe\MSSQL$MICROSOFT##SSEE\sql\query

The question is, how can we move the database to SQL Server 2005, on very different server, leaving the application untouched?

Quick summary, we currently have:

--- Server A: (WSS 3.0) + [windows internal database / SSEE (not sure!)] + DOMAIN X

and we want t

Secured Oracle Provider



Ours is a Asp.net web application. Database is Oracle. Its an Internet Application.

Database will be in one location and Web application in another. Data from Oracle to Web application will be passed over Internet.

We are using EnterpriseLibrary. And provider is System.Data.OracleClient.

We need a provider which encrypts the data while passing data over internet.

Do we need to go for some third party Providers or ODBC ?

Please let me know..
