Unable to load DLL "OraOps10.dll"
I am running into peculiar issue. I am developing a windows based application which connects to Oracle database.
For initial testings, I have created installer and tested on different machines that I have. Each machine has Oracle Client installed and I did not see any problem in running application.
But when I share this installer with customer, he is getting error "Unable to load DLL OraOps10.dll". When asked he mentioned and has shown the Oracle Client installed on his machine and he is able to run other C# applications which connects to Oracle databases.
I do not understand why my application only getting above error. I even tried suggestions shared at One way to fix the "Unable to load DLL (OraOps.dll)" error but still no luck.
I even tried copying executables & DLLs manually on customer's machine. But still facing same issue.
So please help me on what else i can do.
Thanks & Best Regards
Sudhakar Chavali
P.S:
I am using Windows XP operating system and customer is also using same operating system. Both machines are of type 32 bit OS only.
This is the location where customer's oracle client installed: C:\oracle\product\10.2.0\client_1\bin and same is the version in my case too.
We both are using Oracle 10g and .Net framework installed is 4.0
The only thing that comes to mind is a .net version problem. Are you both using Oracle client 10g as well? Do you have an 11g client on your development machine?
There was no .net 4 assemblies in the 10g client, they didn't add that until 11. It's possible that something in his configuration isn't letting a .net 4 application load a .net 2 assembly.
If that's the case, then giving the client an Oracle 11g client will fix the problem.

Unable to load DLL 'OraOps10.dll with a twist
Hi,
So, I have been struggling with an issue for the last couple of weeks that is sending my mad. I receive the following error when attempting to make a connection to a database with my web app:
Error message:
"Unable to load DLL 'OraOps10.dll': The specified module could not be found. (Exception from HRESULT: (0x8007007E)"
I am using
Windows 2008 32bit
Oracle Client 11g
.net v2
IIS7
My apps called CMA, slimier to a more well known app NCSuite
My connection to the database seems to working doing a simple test with a .udl file.
I have attempted the following:
Full re-installing the Oracle drivers following online instruction to clear reg and assembly, several times
Setting permissions on the folder to beyond what they should be
Setting permissions on any folder that refers to oracle
Tried installing ODP.NET just on the off chance it might help
Had a good mess to see if it was something to do with the 64bit issue, but obviously not as Im 32bit
Unfortunately earlier version of the Oracle client are not compatible
One thing that confuses me is why my app would refer to OraOps10.dll rather than the OraOps11w.dll thats being used. Only Oracle 11g has ever been installed on this machine as its a fresh build. The application itself does not directly refer to the OraOps10.dll.
Any thoughts?
RegardsHi,
I'm a bit confused by your statement "+Tried installing ODP.NET just on the off chance it might help+". You can only get that error if you're using ODP.NET in the first place. A UDL file would test an oledb connection, so it's good just to make sure the client libraries are there and tnsnames configured correctly, but otherwise a bit irrelevant to this error.
Anyway, that error occurs when ODP either cant find it's dependencies.. either the right OraOps or client dlls, or finds them but finds the wrong ones. OraOps11 (without the 'w') gets loaded when your application loads the 1.x ODP.NET provider. The provider for .net 2.x and higher loads oraops11w.dll.
The usual cause of this error is from apps including Oracle.DataAccess.dll in the app bin directory, rather than letting it get picked up from the GAC.
I'd start by
1) searching your machine for all Oracle.DataAccess.dll, and rename any outside the Oracle home and/or GAC.
2) if that doesnt do it, use a tool like Process Explorer (http://sysinternals.com) to find out where Oracle.DataAccess.dll is being loaded from, and what version. You need to have a matching OraOps that is the same version as Oracle.DataAccess.dll they actually need to be a matched pair (check the date of the dlls), but its the mismatched version that causes the error.
3) if neither of the above help, use Process Monitor to watch the dll's loaded 'live' to see if there is some sort of permissions issue, but the well known permissions issue that you've probably found information about was specific to 9.2 and 10.2 client, and is not an issue with 11g. That is to say, the OUI sets permissions properly in 11g, but it's still possible an IIS admin may have cranked permissions down too tight.
Additionally,
1) What version of ODP was your app compiled with?
2) What version of .NET framework?
3) What version of 11g client do you have installed, and what did you install it from? ie, 11107.0 full client? or 11107.20 odac bundle?
4) The ODP forum is located here: ODP.NET
Hope it helps,

System.DllNotFoundException: Unable to load DLL 'OraOps10.dll'
Hello,
I'm developing a piece of software for a small business that connects to an Oracle 10g express database I set up. The software is written in c# with VS2008, and has ODP.NET installed. On the computer I'm developing with, the software works perfectly. Unfortunately, when I try to use it on a different computer I get the error message "System.DllNotFoundException: Unable to load DLL 'OraOps10.dll'".
I have already created a redistributable for all the .NET components I need, including Oracle.DataAccess.dll
I think this problem would be solved by installing VS2008 and ODP.NET on every computer needing it, but that's unrealistic. Is there another way to get this program to work?Hi,
At a minimum, you need to install the Oracle core client and ODP provider on the target deployment machine. ORAOPS10.dll is a the unmanaged layer for our provider and gets installed when you install the driver from our installation bundles. That DLL is a dependency of the .NET 1.x assembly and should get installed when you install the ODP component.
I am assuming you are using an older 10.2.0.10 version. In later versions we provide an IC bundle that includes an xcopy redistributable that makes it alot easier to wrap up with your custom install scripts, with earlier versions that reply on a full client you need to use the OUI and install the client and ODP on the target machines where the app will be deployed.

Hi,
I have a asp.net web application running on windows server 2008 with oracle server 10g installed.
now we are planning to run application on another server with same server as database server. but when the deployed on new server the login page comes up and after login System.DllNotFoundException: Unable to load DLL 'OraOps10.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E) exception is thrown. any help would highly be appreciated.Did you run the ODAC installer, OUI or xcopy, or did you just copy over Oracle.DataAccess.dll to the new machine? If the latter, then you need to run the installer to put in all the necessary Oracle DLLs ODP.NET references.

Instalation and Error Message: "Unable to load DLL(OraOps10.dll)"
Hi, I'm not sure if my question is for this forum, but maybe :)
I create very simple application in VS.NET using ODP.NET (see attachment) which just try to connect to oracle database. But when I install this project on different computer without Visual Studio (but Redistribute Package .NET Framework 1.1 is installed!!!) and with database Oracle 8.1.7 an error message occurred:
"Unable to load DLL(OraOps10.dll)"
How can I create some Install project in VS using ODP.NET that can run on other PC ???
How can I solve this problem with loading DLL???
Thanx, TomasTomas,
You will need the Oracle Data Provider for .NET to be installed on the new machine.
Thanks,

Unable to load the support DLL (webaccess setup)
Hi,
I'm installing GW8 SP2 HP3. So far I've installed the domain, PO and GWIA. They work just fine. Now I'm trying to install the WebAccess agent. When I run the setup I receive the following error message:
Unable to load the support DLL:
C:\Users\USERNAME\AppData\Local\Temp\2\{ad3aed10-0f09-11d3-93d8-0008c7392dd7}\WAZAGB32.DLL
When I go to that temp location, the files are all there, including the above mentioned DLL. In my forum searches I found similar messages, but they were all caused by a missing Novell Client. I have the Novell Client 2 SP1 installed. I even installed the latest IR9 update to see if that helped.
I installed the previous hotpatch just fine (GW8SP2HP2). When I try to run the old hotpatch webaccess installer, it fails with the same error. So obviously something changed between the time I installed the previous and this hotpatch on my system. I just can't figure out what.
Does anyone have an idea as to what might be causing this error?

Unable to load gpib-32.dll when running the visual basic 2008 program
I installed NI-488.2 into my PC, window 7 64 bit OS.
In the program >> project> add reference>.NET, I successfully add the NI.4882 into my visual basic program.
By the way, this program worked well in another window 7 32 bit PC.
But when I run the program at ildev(BDINDEX,.........), error comes up as "unable load DLL gpib-32.dll".
So when I looked at c:\windows\system32, I can not fine gpib-32.dll.
Doesn't NI-488.2 driver install gpib-32.dll?
How can I install gpib-32.dll?SeongCho wrote:
Nyc, thank you for your reply.
By the way, I think I did all the link explained.
So I have no problem in adding NI488.2 to my program's reference using "add reference".
The problem is GPIB statement like ildev() looks for "gpib-32.dll".
But there was no gpib-32.dll installed in "c:\windows\system32" so error comes up with "unable to load gpib-32.dll".
I did the same procedure in my another PC(window 7 32 bit OS,my current PC is window 7 64 bit OS), and in that PC I can see the gpib-32.dll in that directory and program run without problem.
I do not know how gpib-32.dll was installed in my previous PC.
Thanks

Have you looked at the example programs for .NET that install with NI-488.2?

I looked at other users machines who aren't having this problem and they have the same Oracle DLLs from the same install that I do too so I am scratching my head trying to figure out what is wrong here and would appreciate any help - and thanks in advance. -
How 2 find ORAOPS10.dll in a 64 bit version
We have a .net application developed on 32 bit using odp.net to communicated with our database. When we deploy the application on a 64 bit server with a Oracle 10 Client Installed we get an: unable to load dll 'oraops10.dll'.
We tried copying the file from the development environment. We then get another error that the files is a wrong version. This is probably because its 32 bit.
How (where) can we get a 64 bit version of Oraops10.dll

Have 2 Database servers at work.
Server 1: Oracle 10g R2 on Win 2003. Used for development
Server 2: Oracle 9i (9.2) on Win 2003. Used by Customers
Our software is a web based program
Problem is when I create a test site on 'Server 2' I get the following error:
Unable to load DLL 'OraOps10.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
I have made a copy of the OraOps10.dll from 'Server 1' and pasted it into the ~Oracle\ora92\BIN directory on 'Server 2', but am still getting the error.
Any help/thoughts would be appreciated.
Thanks in advance
TobyDoes the dll exist on that box? Oracle.DataAccess.Client requires oraops and a client install to work, you cant just use the dll alone.
Hope it helps,

OraOps10.dll and Windows2003 Server
Hi all,
i've following problem:
when starting my c# wep project on my windows 2003 server (oracle 10 client already installed, iis 6.0 installed) i get the following error :
System.Web.HttpUnhandledException: Exception of type System.Web.HttpUnhandledException was thrown. ---> System.DllNotFoundException: Unable to load DLL (OraOps10.dll).
i tried to reset permission on my oracle home folder - no success
i copied the dll into the bin folder of the web project - no success
(restarting server is not possible, because of other applications)
On my windows xp client (vs.net 2003 installed, framework 1.1 and 2.0, odp.net 10 installed and oracle client 9.2 installed) the web project works fine - w/o any problems - why not on the server, the one thing that is different between server and client is the installed vs.net 2003 on my client, but why to install vs.net on the server - this makes no sense in my opinion!
Anybody a solution??

joeYou may need to arrange some downtime :( I think you need to reboot after installing the oracle software. While the added path is in effect for some purposes, anything running as a service won't see the environment change until after a reboot. You might try starting and stopping everything and see if that does the trick.

Unable to load OraOps10w.dll
Hi All,
I am using VS 2005 and trying to connect to an oracle database. My Oracle Client version is 10.2.0.1.0.
I am getting the error Unable to load OraOps10w.dll. I checked in the Bin directory of the Oracle client and i could find only OraOps10.dll.
So what is OraOps10w.dll? Where could i get it? Do i need to install any other version of Oracle Client. Please advise.
Thanks,
Karthick.OraOps10w.dll is the unmanaged dll for 2.x ODP.NET, which was introduced in 10.2.0.2.20. To resolve this, you should be able to just add [10.2.0.2.20 ODAC|http://www.oracle.com/technology/software/tech/windows/odpnet/index.html] into your existing 10201 client home.
Hope it helps,
Greg
