OraOLEDB.Oracle-Provider cannot be found. It may not be properly installed.

I have a traditional ASP page that uses the OraOLEDB.Oracle.1 provider to connect to an Oracle database. The oracle 9 client is installed on the Webserver and the asp page can successfully connect to the oracle database using the Microsoft OLE DB provider for Oracle. The problem with using the Microsoft provider is that the database has a datatype that is not recognized by the Microsoft provider. I cannot understand why the OraOLEDB.Oracle provider is not working. I have verified permissions on the Ora90 directory and it is set to allow EVERYONE read and execute permissions currently. I have .NET apps on the server that use the OracleClient.dll successfully.
Does anyone have any ideas on what I could try to get the OraOLEDB.Oracle provider working?

Just as an FYI for everyone.
The base version of the Oracle Client 9.2.0.1.0 has a known bug with installing DLLs with incorrect permissions for Authtenicated Users. You will see this type of error message when connecting from ASP or ASPX but not client server applications.
This is fixed in 9.2.0.7.0 client patchset, restart and it should work fine. Other scenarios can cause same error like the provider not being installed, the key different is that you can connect via client server but not Web Applications when you are hitting this permissions bug.
Feedback and Comments Welcome

"Provider cannot be found.It may not be installed properly"

Hi All,
I am running into this error "Provider cannot be found.It may not be installed properly" while I am trying to connect to Oracle from Excel VBA.
I had installed both Oracle 10.1 and Oracle 10.2 in the same machine and is working with .NET applications.My .NET applications works fine.But when I try to connect from within the EXCEL VBA,it gives me this error.
This is my oracle client folder structure
Oracle 10.1 -> C:\Program Files\Oracle\product\10.1.0\Client_1
Oracle 10.2 client -> C:\Program Files\Oracle\product\10.2.0\Client_2
Oracle 10.2 ODAC -> C:\Program Files\Oracle\product\10.2.0\Client_1
As part of working around this error,I have uninstalled my 10.2 and now I just have 10.1 in my local machine.
This is the code snippet where the error occurs in VBA
Set Conn = New ADODB.Connection
Conn.ConnectionString = "Provider=OraOLEDB.Oracle;Data Source=datasource;User ID=userid;Password=pwd;CacheType=Memory"
Conn.ConnectionTimeout = 60
Conn.Open
I would really appreciate any help as I have been working around this erro for the last 2 days
Thanks much!

Hi,
Why do you have 3 Oracle homes?
Mutliple Oracle homes on Windows is a pain at best. Oracle's OLEDB and ODBC drivers require that their home be first in your PATH.
Generally you can have as many homes as you want, but can only USE the home that's first in your PATH, and things like OraOLEDB, being a com object, can only be installed into a single home.
In your registry, what does HKEY_CLASSES_ROOT\CLSID\{3F63C36E-51A3-11D2-BB7D-00C04FA30080}\InprocServer32\(Default) point to (the entry for Oracle's OLEDB provider)? Is it the same home that's first in your path if you open a dos prompt and type PATH?
Hope it helps
Greg

Interesting angle on 'Provider cannot be found. It may not be properly installed' error

Hi, I am getting the "Provider cannot be found. It may not be properly installed" message when running a .bat->VBScript script using Windows Task Scheduler. I am not seeing a solution in Google searches. Possibly I am not seeing the similarities because of a lack of detail in posts. Who knows.
Info as follows:
- Installed ODAC1120320_x64.zip using my personal user account.
- Using my personal user account there is no problem. I use file explorer to run a .bat file that in turn calls the VBScript.
- Using the System account and Windows Task Scheduler the script fails with the above error.
- File ACLs for the Oracle home\..\bin directory give full control to the System account
- ACLs for the ORAOLEDB.Oracle registry key gives access to the System account. I am assuming that all other key-value pairs involved in this problem have the same ACLs.
- Hosted on Windows 2008 (VM)
- The scripting language is VBScript, called from a .bat file. Task Scheduler calls the .bat file.
- The scheduled task has the "Run with highest privilages" box checked (same problem with the box unchecked).
- This configuration and script works well on an older Windows 2003 (dedicated) server
- Connection string:
"Provider=ORAOLEDB.Oracle;" &_
"User ID=[DB Schema Name];Password=[password];" &_
"Data Source=[TSN name];"
- I can mess with aspects of the TSN name and file without a change in the error message
Thanks for your help.

We got the same error under windows 2003 SP2 and Oracle 10g release 2. Is there any problem with this provider in this release? We installed downgrade version of this provider, it is working. Is there any other way to avoid this error without going for downgrade?

OraOLEDB.Oracle Provider Not Found- Windows 7 64 bit Excel 2010 32-bit Help

Currently, I have an excel 2010 application that users on Windows XP 32 bit are using to connect to an Oracle 32-bit database and extract data back into Excel. Each time they open the Excel file, the VBA code automatically creates a new connection using Provider =ORA.OLEDB.Oracle Provider. All users using the Excel file have installed Oracle 9.2.1 run-time client on their machine. All of that works well currently for over 100+ users on Windows XP 32-bit
Starting very shortly our company is moving to Windows 7 64-bit. We acquired a test PC with Windows 7 64-bit and Excel 2010 32-bit. We tried to install Oracle 9.0.2 run-time client but we couldn't connect to the database ( even with Sql Plus). We therefore downloaded Oracle 10g 10.2.04 Run-time client. With this installed, we were able to connect to via SQL Plus to the database. However, using the same Excel file and the following same VBA code.
Set cn = New ADODB.Connection
cn.Open ThisWorkbook.getDBCon()
Public Function getDBCon()
getDBCon = "Provider=OraOLEDB.Oracle;" & _
"Data Source=MyOracleDB;" & _
"User Id=" & getDBUser() & ";Password=" & getDBPss()
End Function
I get a "Provider Not Found error". The VBA code and file work perfect in XP 32-bit. It seems going over to Windows 64-bit has caused issues with the file's macro. I am looking for help assessing if I have more of an Oracle Client issue or a Microsoft ADO issue. Any input would be greatly appreciated. Thank You.

@damorgan
Yea agreed with Excel to Oracle comment. This is due to issues with global implementation of an ERP system and the disconnets between IT and Business. Therefore the business intelligence tables in oracle are most easily pulled and acted on by novice PC users via Excel. In the business, Excel is the standard tool novice non-IT people feel comfortable in to share and act on data. Most of these users have no IT knowledge whatsoever, so we create buttons and filters for them to query and then massage in Excel as they see fit.
Having said that, still wondering if it's a ADO or Oracle Client issue. This is something beyond my knowledge. I wouldn't imagine it's the Visual Basic issue since this same file works in Windows XP. I am not in the position to just scrap Excel as the business relies on this in production and I am the only support. What could 64 bit vs 32 bit differences be having here? Thank You.

I have a solution developed in Visual Studio 2012 targetting .Net 4.0. Simplified: Startup project is a WPF library and supporting this library is another project that uses Entity Framework to retrieve data. I have copied the connection strings from my EF project to my startup project, and everything seems to work fine on the development machine.
However, as sson as this project is run on a user's desktop they get the error:

I've already verified that Oracle.DataAccess is referenced in my EF project, and I'm including oci.dll, orannzsbb11.dll, oraociei11.dll, and OraOps11w.dll in my main library (fat installation).
This configuration worked when using the older ADO.Net DataSets, but now I want to use EF 4.4 (DataBase first/model first/whatever it's not Code First) because it's just easier to code against. So obviously I'm missing something when it comes to deploying my solution. Any ideas?
Note that this is a desktop application using MS OneClick.

Same issue:

You mention "Sounds like the client system doesn't have an Oracle client installed."
I am using Win Server 2008 R2. I have installed what i think is the right client. How do i tell?
What is the right client? Where do i get it?

The specified store provider cannot be found in the configuration?

I got the error "The specified store provider cannot be found in the configuration, or is not valid"
while excuting the following command:

this is to pre_generate views to improve Entity framework performance, itruns well for SqlServer.
What is the issue? I checked in machine.config, it seems ok:

Ms sql server linked server with OraOLEDB.Oracle provider session handling

Hi everyone!!
Here's my situation:
I have a MS SQL Server 2008 R2 with a linked server to Oracle via OraOLEDB.Oracle provider.
I use a .net application to open a connection to my sql-server, execute a select that collects data through the linked-server-connection from the oracle database and after that I close to connection to the sql.
It does work so far,
but when I start my application, exit it proberly and start it again it seems that i get the same session as before (which is for some reasons very bad).
Is that the right/normal behavior?
Is there any way to avoid that?!
How does the OraOLEDB.Oracle provider handle the sessions if used in/as a linked server?
thanks and greetings,
exoc

Ｈii Rouann,
Does the error occur when you call the stored procedure from SSIS package and map SSIS variables to the parameters in the stored procedure? Can you run the store procedure from SSMS properly? If you can run the stored procedure from SSMS, the issue seems
to occur due to the date format mismatch between the SSIS variables and the parameters in the stored procedure.
If you cannot run the stored procedure from SSMS as well, the issue should occur due to the incorrect data conversion within the store procedure itself as Tom mentioned.

'ORAOLEDB.ORACLE' provider is not registered on local machine.

Operating System: Windows XP Pro 64-bit
Oracle: 11G Standard Edition One (32-bit)
App: VB.NET (32-bit)
Attempts at fixing problem: 1) Set permissions for users ORACLE_HOME folder as advised. 2) Ran REGSVR32 on ORAOLEDB11.DLL in "BIN" folder of ORACLE_HOME.
Other Info: App runs fine on Windows XP Pro 32-bit machine with Oracle XE (32-bit).
Thanks.

Do you know if the IIS virtual directory in which you are running is configured to support Anonymous access? If it is then you may be running into a permissions problem with the "IUSR_<machineName>" account not having sufficient priveleges to create an instance of the OraOLEDB.Oracle provider.
You could test this by temporarily adding the IUSR_ account to the admin role. If this works, you may want to consider exploring the COM+ technology that allows you to specify a user other than the one defined by IIS for running system level operations (such as establishing a DB connection ).

'OraOLEDB.Oracle' provider is not registered - ODAC 11.1.0.6.10 Beta2

Hello,
I have installed the ODAC 11.1.0.6.10 Beta2 and when working with ASPX pages that use OraOleDB, it raises the following error:
Additional information: The 'OraOLEDB.Oracle' provider is not registered on the local machine.
Do I have to do something else to set the OraOleDB registered? during the installation I selected to install all the components of the Odac (except the MTS service). This app was working fine whith a previos previous intallation of the ODAC 10.2.02.20. (to try the new version, I uninstalled the previous version)
Thanks.

Hello Buddie, how you doing?
I just solved my problem.
Verifying which DLL were missing through OraOleDB.dll, using the tool "Dependency Walker", I downloaded and put them into the respective directories. I'm going to show you.
Must be aware you needn't overwrite any DLL.
In my scenario, having Oracle Client 8.1.7.0, the missing dll are following below:
%ORACLE_HOME%\bin :
- OraOLEDButl.dll
- OraOLEDBrst.dll
- OraOLEDBgmr.dll
- OraOLEDBpus.dll
- OraOLEDBus.dll
%WINDIR%\system32\ :
- DWMAPI.dll
- WINHTTP.dll
- GDIPLUS.dll
Just make sure the OraOleDB.dll registering is complain to the tree DLL dependencies.
I hope it can help you.

OraOLEDB.Oracle Provider

Hi. I have tried posting this inquiry in SQL forums but without a response so far so I am hoping someone here can help me out. Forgive me if this post isn't appropriate for this forum.
I am trying to add a linked Oracle Server to our MSSQL 2005 server but am missing the OraOLEDB.Oracle Provider under Server Objects -> Linked Servers -> Providers in the Object Explorer. (Not really relevant in an Oracle Forum I suppose)
Anyway, I have also considered using a simple OPENROWSET command to attach to the Oracle Instance but unfortunately one of the parameters required is the name of the Provider for the connection which puts me back at square one for resolution.
I seemed to have recalled some time back having downloaded the Oracle Driver for MSSQL but I can't for the life of me find the location I got it from before or if it is still available.
Does anyone know where I can get the driver or where I can get explicit instructions for installing the driver on SQL Server??? I don't want to install the entire Oracle Client just to acquire the 1 driver I need to accomplish my task.
ANY input or suggestions at all would be greatly appreciated.

OraOLEDB.Oracle driver is available in the Oracle client installation (you can either choose an administrator option or custom option during install).
Get hold of a Oracle client setup of version of your choice from http://www.oracle.com/technology/software/index.html

The 'ORAOLEDB.ORACLE' provider is not registered on the local machine.

Sir,
I am having my oracle 11g 64 bit database in RHEL linux 64 bit server. My Visual Studio .Net 2008 64 bit application is running in server having Windows server 2008 64 bit OS and oracle 11.2.0.2.0 client 64 bit.
When I try to connect the database through the oracle client its working fine and I am able to connect through the development mode of visual studio 2008. But when I try to run in the IIS the following error is coming:
The 'ORAOLEDB.ORACLE' provider is not registered on the local machine.
Kindly help me
Thanks in advance

This is not an Oracle database problem, never mind a database server language (PL/SQL or SQL) problem.
The problem you've described is with a Microsoft product, Visual Studio 2008. The server you refer to is Microsoft IIS. The error you list is an error with a Microsoft proprietary technology called OLEDB (part of Microsoft's <i>Component Object Model</i>).
Just where does Oracle PL/SQL and SQL languages, the subject matter of this forum, feature in your problem with Microsoft proprietary technology?

Problems with oraOLEDB.Oracle Provider

Hello,
I recently installed the oraOLEDB.Oracle Provider with no issues. When using an oledbdatareader from a .net app we are receiving weird results when pulling more than 100 records from Oracle 8 database. The reader outputs unreadable data after the 100 record. Interestingly enough this only happens when we select individual fields for example select user_id from users. When we do select * from users everything is fine. Also In this particular database the encoding is UTF8. When we pull from another Oracle 8 instance with no encoding we receive no distorted results. Anybody ever encountered or heard of anything like this?
thanks in advance,
jim.

Your procedure has a single OUT parameter ... and yet it appears you are trying to stuff something into it ... that is never going to work. Additionally everything else about your stored procedure would have gotten you a FAIL grade were you been in my beginning PL/SQL class.
The syntax, a cursor loop, is obsolete and has been for more than 10 years.
The formatting and use of case makes even the few lines written hard to read.
And either no commit ever takes place or you are trying to do incremental commits in origseq: Both of which are bad practice.
This code should use BULK COLLECT to collect all relevant records into an array and then pass the array to origseq ... no loops ... and end with a commit.
