'Oracle.DataAccess error

Hi All,
I have just updated my oracle client from 10g to 11g. After that, I built my windows based application together with a setup project. I install the application in my own laptop and it work fine but when i install the application in other computers(oracle client 9i) and i got the following error:
Could not load file or assembly 'Oracle.DataAccess, Version=10.2.0.100, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Anyone can help me to solve this problem? Please advice. Many thanks in advance.

Could not load file or assembly 'Oracle.DataAccess error on server

I have been building a.NET application on my local Machine Windows 7 and have the 32-bit ODT installed on my machine which works nicely with VS 2010.
I placed it on the server and when I open the page that accesses data from Oracle, I get the below error. Both the server and my local computer have the Oracle.DataAccess
dll installed and both have the same public token 89b483f429c47342. I changed the target CPU from Any CPU to x86 and published a Release build of my project to the server.
Why am I getting the below error?

This was definitely the right answer, I thought ODAC was already installed on the server, but apparently not. I installed the 64-bit OCAC XCopy version on the server and now it works.

Hi Mubarak,
Please firstly make sure you installed SharePoint Foundation 2010 with SP2 in a Windows Server 2012 R2. Since only SP2 slipstream installations are supported on Windows Server 2012 R2

Service Error: File or assembly name Oracle.DataAccess not found

Hi, everyone.
I knew someone had post the similar question before. However, the discussion is not be able to solve my problem. Please give some suggestion.
I got a net1 application use the oracle.dataAccess.dll as reference.
I compiled it on my location machine and updated on the test server.
But the event viewer shows the following error
'Could not load file or assembly' Oracle.DataAccess, Version=1, Version=1.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342, or one of its dependenices. the system cannot find the file specified.
Then I checked my application I realize, the oracle.DataAccess.dll I reference on my local machine is version10g. So I remove the reference and add the dll again (correct version 9i that match the testing enviroment). Becuase the testing environment got 9i installed.
p.s I done the permission stuff for the ora92 folder and reboot is before I update the service.
When I start the service again. I still have the same error. So after whole bunch of checking , re-add the reference and recomplie. I am running out of the solution.
Please if anyone can kindly give a hand before I shoot myself. =(
Thanks in advance
null

after long wait and there still no reply or suggestion from any one. Finally, I managed to solve this problem myself.
Check your oracle.dataaccess.dll which you reference in the project and make sure the oracle.dataccess.dll version whould match the one you want to use.

Error: Cannot find the assembly Oracle.DataAccess

Hi, I've this problem when any program use a connection with Oracle provider over any server (2 distinct server access to Oracle 9i with forms applications).
The specific error is:
Cannot find the assembly Oracle.DataAccess, Version=1.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342.
This problem is resolve (temporary) executing:
Alter Procedure <<Any procedure valid name>> compile
But this is not an elegant solution.
Please, ODP save something else in memory than executing this sentence clear an resolve this situation ??
Exists any solution for this problem ??
Thank for advance..
Claudio

This sounds odd - I don't see how compiling an Oracle procedure would help .NET to locate an assembly - you're not trying to run an assembly inside Oracle are you?
Tell is more about what you're trying to do. If this is just a common program that is running on a server and trying to connect to Oracle, it sounds like ODP is not installed on the computer that is running this code. You should see Oracle.DataAccess in the GAC.

The error seems to be related with temporary tables manipulation, does it?
Has we didnât know what to do we try to import those parcels after dropping a spatial index over the parcelâs table and we succeed with the import.
Those any one has any ideas about this?
And about spatial indexes internals?
Thanks in advance,
Vitor
Versions:
Client:          Oracle10g Data Provider for .NET 10.1.0.2.0
Clientâs OS:     Windows 2003 server
Server:          Oracle Database 10g Enterprise Edition Release 10.1.0.3.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options
Serverâs OS:     AIX 5.2.0.0

Vitor,
Yes, Oracle uses temporary tables as part of inserts/
deletes/updates on a table with a spatial index.
Temporary table usage internally should not
have any issues and we are not sure why this problem
surfaces. Opening a TAR on this with a simplified
testcase (and all config details: # of concurrent
sessions etc.) might help in a better understanding/
resolution of this issue.
In the meanwhile, as a workaround, you can do the
following:
- drop the spatial index
- migrate (insert) the data into the table from the
application
- recreate the spatial index
This will avoid the temporary table issue at hand.

Yes on both of your questions. This is why I am confused as to why this is happening and the really strange this it happens maybe 2 times out of 10 (give or take).

Oracle.DataAccess.Client.OracleException - How do I look up error numbers?

We are getting an intermittent error that doesn't help much and I would like to read up on the error to figure out what to do to fix it. Do any of you know how or where to look up error numbers for this? The error we are getting is: Oracle.DataAccess.Client.OracleException Data provider internal error(-3000)
I have searched www.Oracle.com and done a Google search and the only hit I get is a similar error (error(-3001) for them) that has to do with connection pooling. They didn't get a solution to their post. There are no reference links that come back on my searches.
So, can you help?

Hi,
-3000 means something bad happened internally in the provider. It's a catchall "you should never get here" error. As such, it's usually something the ODP team needs to fix, as opposed to something you can fix in your code.
My best suggestion is to make sure you're using the latest and greatest provider and see if it still occurs. If it still occurs on current versions, you'll probably want to open up a SR with support, enable tracing to generate a "mini dump" when the behavior occurs, and have the dump analyzed.
Cheers,
Greg

Migrating System.Data.OracleClient to Oracle.DataAccess.Client - XSD error

Hi, I'm a newbie using Oracle ODP.NET provider for .NET.
We have a web application that uses XSD to connect to Oracle using the provider System.Data.OracleClient.
We want to migrate from System.Data.OracleClient to Oracle.DataAccess.Client.
Installing and referencing the Oracle.DataAccess.dll all works fine.
Then I changed all the references from System.Data.OracleClient to Oracle.DataAccess.Client and removed the System.Data.OracleClient.dll assembly from the web.config file.
All compiles well, until I run the application, looks like the problem is the parameter use in the XSD file... the error I get is:

Many thanks in advance for any help!

MS OracleClient binds parameters by name. ODP.NET binds by position. If you want to change ODP.NET's default parameter binding behavior, set:
OracleCommand.BindByName = true;
Do this for every OracleCommand that binds parameters.

Oracle.DataAccess.dll Error upon Deployment

Hi,
I have an application which has an optional Database Source setting (SQL | Oracle). The Oracle Database is used only when the application is set to run on Oracle Mode. My problem is when I deploy the application it seems that I need to install Oracle ODP.net even if I desired to run on SQL mode. I tried some work around, I copied Oracle.DataAccess.dll (without installing ODP.net) to the BIN folder of my application and deleting the Oracle reference at the assemeblies in the WebConfig. On the first run I get an error about oracle versions.. but when i refresh the page this error is gone.
Please advise me on what shall be done in this case. I want the on first load the error will be gone.
Thanks

The Oracle.DataAccess.dll is variously located at
client 9i it's at C:\oracle\ora9i\bin
version 10.1 it's at C:\oracle\product\10.1.0\Client_1\BIN
Version 10.2 it's at C:\oracle\product\10.2.0\client_1\ODP.NET\bin\2.x for the .net 2.0 version.
There is also C:\oracle\product\10.2.0\client_1\ODP.NET\bin\1.x for the .net 1.1 version.
I don't have version 11.x so I can't say for that release.
If you used different Oracle Home directories then your locations would be slightly different.

Upgraded to 64 bit Oracle DataAccess.dll and now more open cursors errors

Hi, We recently converted from .net framework 1.1 application to .net 4.0 framework for 64 bit. We installed the 64 bit version of Oracle DataAccess dll. It now seems like we are getting many more open cursor error messages in our application. The open_cursor value set in the database has not changed and other than the 64 bit Oracle and .net 4.0 framework nothing has changed. I was just curious if anyone else that has converted to the 64 bit Oracle DataAccess dll has experienced an increased number of open cursor errors? If so, what was the resolution.
I apprecieate any feedback.
Thanks

What do you have /32BIT flag set to in the assembly? Ie, was it compiled with AnyCPU, x86, etc? You can use corflags.exe with the .net sdk to find out.
Prior to VS2010, the default was AnyCPU which meant it ran as 64 bit on 64 bit OS, and 32 bit on 32 bit OS.
As of VS2010, the IDE defaults to x86, which means it runs as 32 bit no matter what.
32 bit apps need 32 bit odp/client. 64 bit apps need 64 bit odp/client.
The error you're getting usually means you have the wrong bits (32/64) of the Oracle client installed.
Assuming you have the wrong client bits installed, you could either
a) make the app run as the other bits by setting/clearing the 32BIT flag (also by using corflags.exe)
b) install the other bits of Oracle client software. a 32 bit home and a 64 bit home play rather nicely together for the most part, but you need to install them into separate homes.
Hope it helps,
Greg

Unable to load Oracle.DataAccess

Any help on this , please.. I have been trying all sorts of things and nothing seems to workl.

BadImageFormatException occurs when you have a bit mismatch.
1) What is the TargetCPU set to when you compiled?
2) Are you running the app on 32 bit or 64 bit OS?
3) Confirm whether the app is running as 32 bit or 64 bit in the problem environment (open task manager, click the process tab, is there a *32 next to the name?)
4) Did you install 32 bit Oracle client or 64 bit Oracle client?

Unable to get the Oracle.DataAccess namespace

I'm trying to connect to remote 11g Oracle database using Oracle.DataAccess; working on Visual Studio 2008 installed on Windows XP.
I have downloaded and installed Oracle 11g ODAC and Oracle Developer Tools for Visual Studio 11.1.0.7.20 .
I have also installed OracleXEClient.
I have successfully connected to the database in the Server Explored -> Data connection.
I have successfully connected using the Sql data source. The connection String Provider is providerName="Oracle.DataAccess.Client".
But I cant import - use the Oracle.DataAccess;
using Oracle.DataAccess;
I get this error
Error 1 The type or namespace name 'Oracle' could not be found (are you missing a using directive or an assembly reference?)
How can I solve this problem?

Hi Ershad,
Check the value of the ORACLE_HOME variable.
Also check other oracle variables.
Please check this link:

Oracle.DataAccess.dll on Windows 7 64 bit

Hi,
I am migrating a .Net 3.5 windows class library from WinXP 32 bit to Win7 64 bit. I use Oracle 11g 64 bit client to connect to database.
my code works in Debug build but not in Release build. here is the error message:
"An attempt was made to load an assembly with an incorrect format:"
I did not complete uninstall by Oracle Deinstall, and re-install it.
Debug build have a waring:
"Assembly generation -- Referenced assembly 'Oracle.DataAccess.dll' targets a different processor."
Release build still the same incorrect format error.
here is more information:
under C:\Windows\assembly
Oracle.DataAccess 2.112.1.0 89b483f429c47342 AMD64
Oracle.Web 2.112.1.0 89b483f429c47342 AMD64
How should I fix it? should I download and install "64-bit Oracle Data Access Components (ODAC)"? What's difference between ODP.net in Oracle client and in ODAC?
Thank you,
Wes

What do you have /32BIT flag set to in the assembly? Ie, was it compiled with AnyCPU, x86, etc? You can use corflags.exe with the .net sdk to find out.
Prior to VS2010, the default was AnyCPU which meant it ran as 64 bit on 64 bit OS, and 32 bit on 32 bit OS.
As of VS2010, the IDE defaults to x86, which means it runs as 32 bit no matter what.
32 bit apps need 32 bit odp/client. 64 bit apps need 64 bit odp/client.
The error you're getting usually means you have the wrong bits (32/64) of the Oracle client installed.
Assuming you have the wrong client bits installed, you could either
a) make the app run as the other bits by setting/clearing the 32BIT flag (also by using corflags.exe)
b) install the other bits of Oracle client software. a 32 bit home and a 64 bit home play rather nicely together for the most part, but you need to install them into separate homes.
Hope it helps,
Greg

App.config tag oracle.dataaccess.client not recognized on windows 7...

Hi all,
I have an application that is working fine on windows XP. On windows 7, the same application cannot work cause of the tag oracle.dataaccess.client you can see below which is not recognized by the system. As soon as I start the application I get an error

Since this is an oracle section, I think you'll get more help over at the oracle forums.
https://community.oracle.com/community/developer/english/oracle_database/windows_and_.net/oracle_developer_tools_for_visual_studio
I would check the versions of the odp.net (oracle.dataaccess.dll) on both machines. The XP machine probably has the 11g client on it. And the windows 7 machine probably has the 12c client on it.
