Loading Oracle.DataAccess, Version=2.102.2.20 using Reflection
Hi,
I 'm trying to load the Oracle.DataAccess, Version=2.102.2.20 assembly using Reflection in VS.NET2005. But I'm getting the next message:
"Could not load file or assembly 'Oracle.DataAccess.Client' or one of its dependencies. The system cannot find the file specified.":"Oracle.DataAccess.Client"}
fileName: "Oracle.DataAccess.Client"
This exception is thrown by the next code:
System.Reflection.Assembly.Load("Oracle.DataAccess, Version=2.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342");
If I specified the full path of the assembly instead of the fullname then it works; but the idea is to use the assembly fullname instead.
Domebody has any idea how to overcome this exception?
Can you please check if the Oracle.DataAccess, Version=2.102.2.20 assembly is installed in the GAC?

Note: There is some performance penalty associated with assembly bind failure logging.
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].For Adapter Pack 2013 the following Oracle Client(s) are needed:
Supported client versions: Oracle Data Access Components for Oracle Client 12.1, Oracle Data Access Components for Oracle Client 11.2.0.1
And please bear in mind that both the 32- and 64 bit versions are needed.

Could not load file or assembly 'Oracle.DataAccess, Version=2.102.2.20
I have a C# windows application that started to give me the error when I try to run it:
Could not load file or assembly 'Oracle.DataAccess, Version=2.102.2.20.
I was adding and removing references and re-build when this started. The builds are successful Is there anything I can do to correct it? Other apps that I uses ODT are fine. The full error is below.
Thanks,

Do let me know if you were able to resolve it.
I am getting below message.

Where can I find Policy for 10.2.Oracle.DataAccess version 2.102.2.20?
I have under C:\oracle\product\10.2.0\client_2\ODP.NET\bin the following folders:
1.x
2.x
But under C:\oracle\product\10.2.0\client_2\ODP.NET\PublisherPolicy, I could only find:
1.x
How do I get the policy for 2.x ?
Thank youThank you SKJ.

Hi All,
While trying to access oracle database from SharePoint facing "Could not load file or assembly 'Oracle.DataAccess, Version=2.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified."
How to fix this issue? Thanks in advance!Hi,
According to your post, my understanding is that you get error while access oracle database in SharePoint.
You can set “Enable 32-bit Applications” to true in the application pool for the web application, then check whether it works.

Could not load file or assembly 'Oracle.DataAccess, Version=2.111.6.20
I have visual Studio 2008 and ODAC installed on Winows 7, my VS2008 application retrieves data from Oracle Db 10g xe. I get this error report wih every attempt to connect and interact wih the database:
"Could not load file or assembly 'Oracle.DataAccess, Version=2.111.6.20,
Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies.
The system cannot find the file specified."
What could be the issue? The same code that worked on Vista is the one returning this error report.I wonder if you could try the following command:
gacutil.exe /l Oracle.DataAccess
This should display the version number of the current assembly that it is GACed. In case that does not correspond to the version 2.111.6.20 then try:
gacutil.exe /u Oracle.DataAccess
and then find the path to the Oracle.DataAccess.dll assembly and issue the following command:
gacutil.exe /i {path}/Oracle.DataAccess.dll
The first command will display the version of the newly GACed assembly. If it still not what you are looking for please pass along the version that it is displayed.
In case the version will match 2.111.6.20, then retry to use VS2008 to connect to your Oracle DB. -
Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0
Hello Everyone,
I am simply trying to insert into an oracle database table. When I try to run the insert from my visual studio program after a button is clicked the program stops and I get "Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0" error.
Why is this? I have added the reference and put "using Oracle.DataAccess;" in the file. The code is below. Any suggestions?
OracleConnection Con = new OracleConnection(ConfigurationManager.ConnectionStrings["ConnectionString1"].ToString());
OracleCommand sqlCmd = new OracleCommand();
//OracleDataReader dr;
sqlCmd.Connection = Con;
Con.Open();
sqlCmd.CommandText = "INSERT INTO FGID values (0, 0, 0, ' ', sysdate)";
sqlCmd.ExecuteNonQuery();
sqlCmd.Clone();
MessageBox.Show("Record Inserted!");
M.N.Hi Boa_nerges,
>>Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0" error.
Whether all projects have the same issue?
Please make sure that it is not the platform target issue in your project property. Or the setup version issue.

Could not load file or assembly Oracle.DataAccess, Version=4.112.2.0
Hi There..
I'm running the follows:
1. OS : XP SP3
2. VS 2010
3. ODP Net 11.2.0.2.0
When I set the ASP NET target framework to .NET 4 all running normally. However, if the set target to .NET 2 appears error "Could not load file or assembly Oracle.DataAccess, Version=4.112.2.0".
What could be the problem ?
Thanks,
IqbalJust figure it out..
use assembly binding when targetted framework is 2.0
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Oracle.DataAccess" publicKeyToken="89b483f429c47342"/>
<bindingRedirect oldVersion="4.112.2.0" newVersion="2.112.2.0"/>
</dependentAssembly>

.. and all running back normally :D -
Could not load file or assembly 'Oracle.DataAccess, Version=2.112.3.0
Hi,
I am using windows 7 64 bit Enterprise Edition, Visual Studio 2010 Premium, and my app is built using .net framework 4.0. I downloaded and install ODP.NET 11.2.0.32 but when I add reference Oracle.DataAccess to my app, its giving me the following error, *"Could not load file or assembly 'Oracle.DataAccess, Version=2.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified."*
I have checked other threads on this same topic, but I found that I have proper version (64bit) of ODP.NET as per my OS, Visual Studio & .net framework.
Am I missing something, please help.Hi,
I manage to resolve the error, the error is though due to a different reason,
I was trying to add ODP.Net 64bit reference directly to a Web Site project in Visual Studio 2010, then find out that this is not possible as the web site builds based on aspnet worker process, and that is 32bit, hence there was a problem referencing the 64bit ODP.NET assembly.
So I created a class library project for any cpu and refer the 64bit assembly in there, and refer the class library project in the main web site, and the problem solved. -
Oracle.DataAccess, Version=2.111.5.10
Hi,
I am trying to compile a project. One of the dependent projects needs the Oracle.DataAccess.dll but for some reason it's missing and i get the error.
The type 'Oracle.DataAccess.Client.OracleConnection' is defined in an assembly that is not referenced. You must add a reference to assembly 'Oracle.DataAccess, Version=2.111.5.10, Culture=neutral, PublicKeyToken=89b483f429c47342'.
On the net i found many versions to download for ODP.NET but i dont know which on to download for getting the correct verison of the dll.
Can someone help me with this?
ThanksODP.NET 2.111.5.10 was the 11g Beta 1 version. It is no longer available. You can use the the Beta 2 version: 2.111.6.10.

Could not load file or assembly 'Oracle.DataAccess, Version=2.111.7.20,
can any one provide a patch or way around on windows 7 64bit amd, for odp.net 11g, as the policy doesnt dot get registered for amd64 bit platform in c:/windows/assembly, one can see policy for 'Oracle.DataAccess 2.111.7.20 0n x86 but not for amd64.
help in this regard would be highly appreciated11.1.0.7.20 simply does not exist for x64.
The highest x64 version is currently 11.1.0.7.0.
If you need 11.1.0.7.20 functionality, you'll need to run the app as 32 bit, at least until 11.2 comes out (due out Q1CY2010)
Hope it helps,

Unable to load Oracle.DataAccess
Hi ,
I have created a website project on .net framework 4.0 in Visual Studio 2010 . But I am unable to add reference the Oracle.DataAccess dll. It is continously throwing the error " unable to load assembly Oracle.DataAccess . The system cannot find the file specified. "
But when I tried adding the reference in a web application project , it gets added. But when run the project it is throwing the same error. On the web page the error thrown is this :
An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

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?
Cheers,

I have done some diagnostic work, and it appears to me that Policy.1.102.Oracle.DataAccess is being invoked, which redirects to ODP version 1.102.3.0. The problem is that in the GAC, and in my application's /bin directory, the Oracle.DataAccess version is 1.102.2.20. I don't think that 1.102.3.0 exists on this server, and I don't know how to get it. Is it from a patch that might need to be installed?
How can I fix this? I'm not very experienced with assembly configuration, binding redirects, and all that. Any help would be appreciated.

Any help on this is greatly apprecitaed
-Jyothish GeorgeWhat version of the client / odp.net are you using?
I took your code and pretty much pasted it into Visual Studio Express:
Module Module1
Sub Main()
TestOracle()
TestMicrosoft()
End Sub
Private Sub TestOracle()
Dim builder As New Oracle.DataAccess.Client.OracleConnectionStringBuilder
builder.DataSource = "lt10gr2"
builder.UserID = "scott"
builder.Password = "tiger"
Dim oraConn As Oracle.DataAccess.Client.OracleConnection = New Oracle.DataAccess.Client.OracleConnection(builder.ConnectionString)
Dim oraCMD As New Oracle.DataAccess.Client.OracleCommand("SELECT empno, ename FROM emp", oraConn)
Dim MyDA As New Oracle.DataAccess.Client.OracleDataAdapter(oraCMD)
Dim ds As New DataSet
MyDA.Fill(ds)
End Sub
Private Sub TestMicrosoft()
Dim builder As New System.Data.OracleClient.OracleConnectionStringBuilder
builder.DataSource = "lt10gr2"
builder.UserID = "scott"
builder.Password = "tiger"
Dim oraConn As System.Data.OracleClient.OracleConnection = New System.Data.OracleClient.OracleConnection(builder.ConnectionString)
Dim oraCMD As New System.Data.OracleClient.OracleCommand("SELECT empno, ename FROM emp", oraConn)
Dim MyDA As New System.Data.OracleClient.OracleDataAdapter(oraCMD)
Dim ds As New DataSet
MyDA.Fill(ds)
End Sub
End ModuleIt ran with no errors on my system.

Hi,
My application uses ODP.net to connect to Oracle and can run successfully within Visual Studio 2005 , but if I copied .exe to another folder (outside MS Visual Studio) then I got the error:
Could not load file or assembly 'Oracle.DataAccess, Version=2.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
There are two entries in my references, I pointed to Oracle.DataAccess 2.102.2.20 (the one in ODP.net)
Oracle.DataAccess 10.2.0.100 V1.0.3705 c:\oracle\product\db_1\bin\Oracle.DataAccess.dll
Oracle.DataAccess 2.102.2.20 V2.0.50727 c:\oracle\product\client_1\odp.net
bin\2.x\Oracle.DataAccess.dll
Anyone can help?
Thanks
LizHi,
Oracle's ODP.net is client version specific, so 10.2 Oracle.DataAccess.dll requires the corresponding version of OraOps10(w).dll which comes with Oracle.DataAccess.dll, as well as a 10.2 client.
You can not distribute the 10.x Oracle.DataAccess.dll and expect it to work on a 9.x client.
If you know your users will have SOME version of ODP and Oracle client installed, you'd have to compile your app with the lowest version of ODP (9.2) in order for it to work on all installs.
We didnt have an ODP in 8.x, so that's right out.
Instant client is still an Oracle client, its just in a different form. The 11.1.6.20 odp comes with instant client so you dont need to download it seperately, but as far as getting a better understanding of what it is please see the following:
http://www.oracle.com/technology/tech/oci/instantclient/index.html
Just fyi, System.Data.OracleClient (Microsoft's ODP for Oracle) that comes with the .NET framework is not tied to any particular version of Oracle client, so could be used with any version of client install. It doesnt have as much cool stuff as Oracle's ODP does though.
Hope it helps,
Greg
