• There are 2 versions of Oracle.DataAccess on the system with the same public token

  Hello
  can someone please explain this
  1 Oracle.DataAccess... x 86... 2.112.1.0... 89b483f429c47342
  2 Oracle.DataAccess... x 86... 2.112.2.0... 89b483f429c47342
  
  I have a reference in Visual Studio to one of these DLLs. My question:
  (1) what are the differences?
  2. what assembly is loaded by my application?
  
  greetings and thanks
  Ellen

  Hi Ellen,.

  All versions of the ODP assemblies have the same public key token. The difference is your case is you two versions (2.112.1.0 and 2.112.2.0) installed, and the difference between new features, bug fixes, etc.

  ODP also installs policy files by default that can come into play here, but it depends on which version you installed last. If you have installed 2.112.2.0 last, then the policy file would automatically redirect apps looking for 2.112.1.0 to use 2.112.2.0 instead.

  If you have installed 2.112.1.0 last, then the file 2.112 strategy would only redirect apps more 2.112.1.0 to use 2.112.1.0.

  If you're wondering how to determine what your application assembly IS actually responsible, the best way is via a tool like Process Explorer, which will allow that see you what libraries are loaded into a process.

• Oracle.DataAccess 32 bit and x 64 with a build? There is no corresponding version?

  We used Oracle.DataAccess to generate a .net assembly. version has been 10.1.0.400. I can't seem to find the x 64 native install for this 10.1.0.400 version we are running IIS in 64-bit mode. so I need an x 64 native bit Assembly.
  
  We deploy our .net assembly for a 32-bit and x 64 bit machines. so I need to install a version of Oracle.DataAccess with the same 32-bit and x 64 bit version.
  
  I can't find a version in common 32-bit and x 64 bit.
  
  It seems that the closer, I can get is 2.102.3.2 for x 64 and 2.102.2.20
  
  I have no problem re-construction of the Assembly, and as long as I can get the same fix on both 32 bit and x 64 bit version in the GAC, it should work very well. help, where can I find a corresponding 32-bit and x 64 bit version to install?

  Hello

  Yes, you must have a support account in order to login to metalink and get the fixes.

  Part of the ODP.NET installation includes installation of policy files in the GAC which redirect use the latest version installed, so I think you should be fine compilation on 10.2.0.2.21 x 86 (for example) and the distribution to the 10.2.0.3.02 x 64. You must compile a version<= the="" version="" you="" want="" to="" be="" able="" to="" run="" it="" on="">

• Intermediate language of the oracle.dataaccess.dll version

  Is there an intermediate version of the oracle.dataaccess.dll that we can use to compile 64-bit applications using 32-bit computers?
  
  We develop our applications on x 32 and deploy on x 64 (it is strictly enforced by our Organization. This means that there is no option for execution of x 32 code on an x 64 server).
  
  The oracle.dataaccess.dll only comes in 2 versions from what I can tell; x 32 or x 64. This forces us to use x 64 build servers. We need the x 32 ODP installed on our machines to dev for the development and the x 64 ODP installed on the servers of x 64 compilation. Dev of 32-bit machines cannot compile an application with an x 64 native dll.
  
  Example:
  1. create a new class library.
  2. Add the oracle.dataaccess reference.
  3. change the platform target in the properties of the project to x 64.
  4 compile the application.
  5 examine the dll in the bin directory. (I used the reflector, but you can use the corflags util)
  
  The target platform for the class library is x 64. The target platform for the oracle.dataaccess.dll is x 86. Application will not work when you run it as x 64.
  
  ODP.NET is the only 3rd-party product .NET we use which doesn't seem to have an intermediate language dll, and so the only reason why we allocate and maintain separate x 64 build servers to compile our code for x 64 deployment.
  
  It's been a while since I looked into that, so I was wondering if there is a solution now.

  I guess the poster is after a fully managed version of the provider, but maybe not.

• Could not load file or assembly ' Oracle.DataAccess, Version = 4.112.4.0?

  Hi guys,.

  As the title says "could not load file or assembly ' Oracle.DataAccess, Version = 4.112.4.0. The program crashes when I try to run the following code.

  Any help would be appreciated.

  Hello

  This occurs generally when there is an inconsistency in the application of ILO version and the version of ODP.NET bits.

  If you compiled/built the application with Any CPU option, please modify X 86 or X 64 and build and run the code.

• Oracle.Dataaccess.dll using unmanaged for 32 and 64 bit Winform application.

  Hello

  I am new to oracle ODP.

  I have a few questions about her.

  1. If I give the reference only and do not include gac Oracle.Dataaccess.dll (suppose 2.11.3.XX) in my project and the client system has the access.dll of oracle version 2.11.2.XX(or autres) then what happens?

  Be it use the 2.11.2.xx DLL to GAC or error.

  2. I need to create some app for 32 and 64-bit client then should I develop a version for two separate, or are there other alternatives (I can't use the managed oracle DLLS due to .net 2.0).

  I've already lost two days on managing versions of oracle as oci.dll ddll, oraop11s.dll etc.

  Please suggest any other alternative if you have

  Thank you

  I think that if you run an application on machine Win x 64 with AnyCPU, 64-bit .NET will be always charged. I don't think you can change this even if you try to load a 32-bit DLL. There may be a way, but I do not know myself.

  If you ODP.NET 11.2.0.3 on your system, I don't see why you need to install an earlier version of ODP.NET, such as 11.2.x

• x 64 application entity Framework using Oracle.DataAccess.Client

  I am trying to build a x 64 application Entity Framework using the current Oracle.DataAccess.Client.  I can launch the application as Any CPU and x 86 using the managed provider, but when I compile for x 64, I get the error below when running.

  Alex,

  Finally, we have solved the problem.  It turns out that we had a bad x 64 home path in the PATH variable.  I lost track of what it was originally, but I'm sure the x 64 bin path was correct. I did not notice that it was wrong, until I tried to install the full client and began to see an error indicating that it was missing a dll.  This led me to a post on the forum, in which you indicated that the PATH variable has not been set (ODAC 12 c for xcopy issues).  In our case, it is not missing, just fake.

  This is the behavior that we see if the PATH variable for the home directories and bin is incorrect:

  • Full client: an error of external system (no exceptions).  The error message is that the oraons.dll is missing.
  • XCOPY customer: generates an exception without error message.  The Exception.Message property is empty and there is no inner exception.

  Can the ODP team can add a meaningful message for this exception?  If the exact error cannot be highlighted during execution, a generic name on the path audit would help enormously.  I must have looked at it a dozen times and didn't notice that it was false.  If I had no idea that this could be the cause, it would be discussed more in detail, or had someone else Verify that it was correct.  I hope that we would have solved much earlier.

  Thank you.

I have a batch file that executes corflags on about 15 dll from a project that gives me an BadFormatImage exception, and I had made a mistake in the batch file.

• System.Data.OracleClient migration to 4 Oracle.DataAccess issues

  I'm trying to convert a great demand out of the obsolete microsoft api to oracle dataaccess.

  But I faced a no-go - possible.

  I have this request:

  UPDATE TSUTCMP0

  SET

  DT_INI_CMP =: DataInicio / * I just omitted other parameters to simplify * /.

  WHERE

  CD_SEQ_CMP =: Código

  Then to run this query and many others I like the following:

  using (var = new TransactionScope() scope)

  using (var conn = MethodToCreateConnection()) / / this method simply creates: DbProviderFactories ("Oracle.DataAccess.Client"). CreateConnection()

  using (var cmd = conn. CreateCommand())

  {

  cmd.CommandText = requesting one;

  var p is cmd. CreateParameter();

  p.ParameterName = "DataInicio";

  p.Value = someDate;

  cmd. Parameters.Add (p);

  cmd ExecuteNonQuery());

  }

  This used to work using microsoft api. I have hundreds of querys, using parameters.

  When I run the present by using the Oracle.DataAccess, I get the following:

  {ORA-00932: inconsistent data types: expected DATE obtained NUMBER}

  In this case, the column in the table is DATES. I inspected the OracleParameter p and DbType is of type DateTime and OracleDbType is TimeStamp. Tried to force OracleDbType far without success.

  I also queries with columns of type DATE that stores the date and time.

  I don't know what I'm missing.

  MS OracleClient binds parameters by name. ODP.NET links in position. If you want to change the ODP. NET default binding behavior, set:

  OracleCommand.BindByName = true;

  
  

  Do this for each OracleCommand object that binds the parameters.
  

• Release of the ODAC 4 &amp; 5 - Oracle.DataAccess.dll 4.112.3.0

  Has anyone else noticed that ODAC version 4 and 5 have the same 4.112.3.0 AssemblyVersion?

  Oracle (ODAC) for Windows data access components

  It took me a while to spot the problem.  I use Entity Framework 5 and hitting a machine with version 4.  He threw a completely misleading exception on the laundry.

  System.Reflection.TargetInvocationException: Exception was thrown by the target of a call. -> System.TypeInitializationException: the initializer for type for 'Oracle.DataAccess.Client.OracleConnectionStringBuilder' threw an exception. -> System.TypeInitializationException: the initializer for type for 'Oracle.DataAccess.Client.RegAndConfigRdr' threw an exception. ---> System.Configuration.ConfigurationErrorsException: MySchema.MyPackage.MyProcedure.RefCursorMetaData.CUROUT.Column.1 is not valid

  to Oracle.DataAccess.Client.RegAndConfigRdr.RetrieveInfoFromConfig (NameValueCollection nvc, Hashtable & schemaTable, Boolean bIsCallFromODT)

  to Oracle.DataAccess.Client.RegAndConfigRdr... cctor()

  Since version 4 ODAC has been installed, the machine had Oracle.DataAccess.dll (4.112.3.0) in the GAC.  So, my application could not use my local copy of Oracle.DataAccess.dll (4.112.3.0) of version 5.

  There are problems with having the AssemblyVersion similarly for version 4 and 5.  Can we get an extra release with an updated version?

  There are two questions in your last post:

  (1) Oracle.DataAccess.dll versioning

  (2) DLL's Client Oracle unmanaged referenced by Oracle.DataAccess.dll

  The forum post you quote refers to the #2 problem.

  Problem #1, preferred the ODP.NET team is at version every single Oracle.DataAccess.dll version. We can not due to a conflict with the policy of general correction of Oracle. With the help of AssemblyInformationalVersionAttribute is the best compromise.

  If you have already downloaded an Oracle patch, you will notice the files share the same version number as other patches within a family group of patches Oracle. With each new group of patches or major version, Oracle.DataAccess, dll can then increase its version, just like every other DLL of Oracle.

• Could not load file or assembly Oracle.DataAccess

  I have a VB.Net application that worked fine on a Windows 2003 32-bit secure server for many months. Exe has already been compiled on a 32-bit Vista machine and then the exe has been copied to the server. Today, I was delivered a new 64-bit Windows 7 computer. I installed the 32 bit ODAC 11.2.0 and added a reference to Oracle.DataAccess.dll in Visual Studio 2010. The program compiles and runs normally on my 64 bit Windows 7 computer. In Visual Studio 2010, I 'CPU target' defined on x 86.
  
  When I copy the exe on the 32-bit server, the following error message is returned: "could not load file or assembly Oracle.DataAccess.
  
  The server has two facilities of ODAC 32bits, 11.2.0.2 and 10.2.0. Why does this work?
  
  Published by: Francis November 1, 2012 13:02

  It's been awhile that I'm on version issues, so I'm a little fuzzy, but I think the problem here is that you develop against a newer version (even if only a little) of the Assembly, that which exists on the deployment target computer. There are policy files to redirect the old versions of the assembly to the latest version installed on the computer, but it does not work to redirect a newer version (i.e. 2.112.2.0) downwards (i.e. 2.112.1.0).

• How to refer to 64-bit Oracle.DataAccess.dll in VS2010?

  Hello!
  
  We installed the ODAC 64-bit 4.112.2.0 on our new developer computers. With the 32-bit version of the ODAC, we would do this option to add the oracle references: Add reference-> tab .NET and add Oracle.Web.dll and Oracle.DataAccess.dll. But after our transition to 64-bit files exist no more. We could do something like make a local reference (include the bin folder in project and place the files and point of reference to them for an example) but this does not seem like a good solution. Has anyone else experienced this problem and solved?
  
  /regards

  You need not reference on x 64 version. You can add the reference on x 86 version. If you want to run the VS project, you need x 86 version customer Oracle VS x 86 application.

  The two DLLS ODAC (x 86 and x 64) has the same signature. If you build the project with the option "any cpu" then right what ODP.NET version is used for execution.
