How much faster is Oracle.DataAccess.Client over System.Data.OracleClient ?

Ok, I can use two differenct data providers in VisualCSharp/.NET:
1.) MS built-in data provider:
using System.Data.OracleClient ;
2.) Oracle ODP.NET data provider:
using Oracle.DataAccess.Client ;
How much faster is Oracle over the built-in access provider ?
Does Oracles ODP use MS basic ADO.NET as underlying layer
or does it bypass it ?
What are the other advantages when I use Oracle ODP?
Is there a side-by-side comparison chart between the two access methods ?

I would say that it is both for speed and for functionality. The ODP data provider has Oracle specific functionality that is not available via the MS data provider.
From the ODP.NET page:
ODP.NET includes many features not available from other .NET drivers, including a native XML data type, the ability to bind array parameters, RAC tuning, and statement caching.

Oracle 9i Client and System.Data.OracleClient Problems

I have an application server that has an ASP.NET webpage that queries an Oracle database on another machine through ODP.NET.
The app server's machine's OS is Microsoft Windows XP SP2 with IIS and .NET 2.0 Framework installed and configured correctly.
The following Oracle software is installed (from OUI inventory listing)
Oracle Services For Microsoft Transaction Server 9.2.0.7.0
Oracle ODBC Driver 9.2.0.7.0
Oracle Provider for OLE DB 9.2.0.7.0
Oracle Objects for OLE 9.2.0.7.0
Oracle Data Provider for .NET 9.2.0.7.0
Oracle 9i Client 9.2.0.1.0
Sun JDK 1.3.1.0.1a
When the ASP.NET page attempts to connect to the Oracle instance on the remote machine via the Data provider I get the following message...
System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Exception: System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
Source Error:
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.
<<snipped>>
I know the connectivity between the client on the app server (SQL*Plus: Release 9.2.0.1.0)
and the remote database (Oracle Database 10g Enterprise Edition Release 10.2.0.3.0)
is working since sqlplus sessions connect and the NET Manager tests through Local Service Naming succceed.
I've tried the "ORACLE_HOME permission changes" solution for Autenticated users as articulated here ....
http://jasondotnet.spaces.live.com/blog/cns!BD40DBF53845E64F!122.entry
but the error persists.
In the list of oracle installed products above, I installed the first 5 (ODP.NET) before the last 2 (Oracle 9i client). Would this matter ? At first I thought perhaps the ODP.NET component didn't "know" about the client since it was installed before there was one on that app server.
Feeback much appreciated.

Well I figured it out. I guess...
1) Uninstalled all Oracle Software Products
2) Rebooted the machine.
3) Manually removed C:\oracle\ora92\.
4) Installed and configured the following
* Oracle 9i Client 9.2.0.1.0
5) Installed and configured the following
* Oracle Services for Microsoft Transaction Server 9.2.0.7.0
* Oracle ODBC Driver 9.2.0.7.0
* Oracle Provider for OLE DB 9.2.0.7.0
* Oracle Objects for OLE 9.2.0.7.0
* Oracle Data Provider for .NET 9.2.0.7.0
6) Gave the following accounts Full Control over the ORACLE_HOME directory
* ASP.NET Machine Account
* Internet Guest Account
* Launch IIAS Process Account
6) iisreset
Conclusion....
The order in which Oracle components are installed does matter.

DBProviderFactories.GetFactory("Oracle.DataAccess.Client") very slow

The call to System.Data.Common.DBProvidersFactories.GetFactory("Oracle.DataAccess.Client") is taking over 2 minutes to return on my computer. By comparison, calls to GetFactory() for the System.Data.SqlClient and IBM.Data.DB2 takes less than a second.
Even more strange, the same call is very fast if I am running the code inside of the VS2010 debugger.
ODAC version 11.2.0.1.2 (32bit version)
Windows 7 64 bit
.NET 3.5 SP1
Oracle server - not relevant since test pgm is not connecting to a serve.
Code developed with VS 2010.
Test pgm built with:
- Target CPU=32 (so app runs as 32bit mode, instead of 64)
- Target Framework = .NET 3.5 SP1
The call has not always been this slow. I have been running with ODAC 11.2.0.1.2 since it's release. But, IIRC, the slowness just started several weeks ago.
Below is the test pgm:
Imports System.Configuration
Imports System.Data.Common
Module Module1
    Sub Main()
        CreateFactory("Oracle.DataAccess.Client")
        CreateFactory("System.Data.SqlClient")
        CreateFactory("IBM.Data.DB2")
    End Sub
    Sub CreateFactory(ByVal providerName As String)
        Dim sw = New Stopwatch
        sw.Start()
        Dim factory = DbProviderFactories.GetFactory(providerName)
        sw.Stop()
        If factory Is Nothing Then
            Throw New Exception(String.Format("DbProviderFactories.GetFactory({0}) failed", providerName))
        End If
        Console.WriteLine("DbProviderFactories.GetFactory({0}) call took {1} secs", providerName, sw.Elapsed.TotalSeconds)
    End Sub
End ModuleThe output I get is:
DbProviderFactories.GetFactory(Oracle.DataAccess.Client) call took 130.1584958 secs
DbProviderFactories.GetFactory(System.Data.SqlClient) call took 0.0001462 secs
DbProviderFactories.GetFactory(IBM.Data.DB2) call took 0.1252213 secs
Please let me know if you need any more information. All help is appreciated.
Jim

As I mentioned before, if I loaded the DBProviderFactory object, for the IBM.Data.DB2 provider, loading the Oracle.DataAccesss.Client provider ran quickly. The IBM.Data.DB2 provider always using a distributed transaction to communicate with the database. So, my guess is that the IBM DBProviderFactory was doing work to prepare for a distributed transaction. And this prep work allows the Oracle DBProviderFactory to run much faster.
So to test my theory, I created a TransactionScope object, before creating the Oracle DBProviderFactory. See new code below:
<pre>
Sub Main()
Using ts = New Transactions.TransactionScope()
CreateFactory("Oracle.DataAccess.Client")
End Using
End Sub
Sub CreateFactory(ByVal providerName As String)
Dim sw = New Stopwatch
sw.Start()
Dim factory = DbProviderFactories.GetFactory(providerName)
sw.Stop()
If factory Is Nothing Then
Throw New Exception(String.Format("DbProviderFactories.GetFactory({0}) failed", providerName))
End If
Console.WriteLine("DbProviderFactories.GetFactory({0}) call took {1} secs", providerName, sw.Elapsed.TotalSeconds)
End Sub
</pre>
And this was the result:
DbProviderFactories.GetFactory(Oracle.DataAccess.Client) call took 0.1925129 sec
a dramatic speedup.
Is this expected behavior? More importantly, is there a fix to make loading the Oracle DbProviderFactory faster without requiring the creation of a TransactionScope object?
Thanks,
Jim

Oracle.DataAccess.Client - DbProviderFactories.GetFactory

Hello
I was inspired by this article http://www.oracle.com/technology/oramag/oracle/06-winsupp/win06odp.html
And been trying to switch my project over from "System.Data.OracleClient" (seems like it's not friendly with TransactionScope) to ODP.NET "Oracle.DataAccess.Client". I failed from get go:
Code:
DbProviderFactory oDbFactory = DbProviderFactories.GetFactory("Oracle.DataAccess.Client");
Keep getting System.Configuration.ConfigurationErrorsException saying:
+"Failed to find or load the registered .Net Framework Data Provider."+
In my futile attempt to resolve this:
STEP 1: In machine.config
* Under \\configuration\configSections\, *add:
<section name="oracle.dataaccess.client" type="System.Data.Common.DbProviderConfigurationHandler, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=89b483f429c47342" />
* Under ..\system.data\DbProviderFactories\, *add:

STEP 2: I checked my assembly cache it's there:
Code:

See, I'm sure the assembly has been installed and in machine.config I used the right key/version. Weird thing is, Red Gate's reflector won't allow me to "Open" (from Cache) the dll, this prevented me to check if there exists "Oracle.DataAccess.Client.OracleClientFactory" within the assembly. So I select "Copy Local" and examined the dll from "Red Gates Reflector". There's no "Oracle.DataAccess.Client.OracleClientFactory" in the dll ???
RedGates Reflector - Screencap:
http://www.codeguru.com/forum/showthread.php?p=1831221#post1831221
STEP 3. Somebody advised to check and make sure "msvcr71.dll" is found under "ORACLE_HOME\bin" and if not copy from "D:\WINDOWS\system32". I did, it's ALREADY there.

Thanks just installed from http://www.oracle.com/technology/software/tech/dotnet/utilsoft.html
It seems version is "2.111.6.20" - from machine.config there's a new line
<add name="Oracle Data Provider for .NET" invariant="Oracle.DataAccess.Client" description="Oracle Data Provider for .NET" type="Oracle.DataAccess.Client.OracleClientFactory, Oracle.DataAccess, Version=2.111.6.20, Culture=neutral, PublicKeyToken=89b483f429c47342" />
i added reference to it from Visual Studio. It's working now.
There were two options: one for client, the other for server. I don't understand what it means but stick to "Client" which was the default. Is this okay?
At the end there was a reminder "Run Oracle Providers for ASP.NET SQL scripts located in D:\OracleODPNET\ASP.NET\SQL directory."
Anyway, I'm verrrry glad this is working now many thanks!!! (I feel like 10 years older)

Oracle.dataaccess.client,oracle.dataaccess.dll

I am new to this environment and am trying to write a vb.net application using oracle 9i database. How do i get oracle.dataaccess.client and .dll downloaded and installed so the studio will be happy ??
George

Firstly, welcome, and I hope you get off to a good start. You can start by downloading the ODP.NET software from the ODP.NET homepage:
http://www.oracle.com/technology/tech/windows/odpnet/index.html
Next I would take a look at John Paul Cook's introductory article:
http://www.oracle.com/technology/pub/articles/cook_dotnet.html
There is also sample code that gets installed when you install the ODP.NET software.
My series of Oracle Magazine articles is here:
http://www.oracle.com/technology/pub/articles/tech_dev.html#dotnet
Though they are all in C# some might be useful to you.
Thanks, and good luck!

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.

How much fast are the new iMac's?

I've been looking at upgrading my G5 PowerMac for a while and now Apple has just updated the iMac. How much faster are the new models over the just superseded ones and my G5 (spec below).
I mainly us it for my work with Photoshop CS2 and the G5 does a great job most of the time but is showing it's age. I was looking at the 2nd model but for not much more you can get the 27inch screen with better upgrade options.

Hi Craig,
even the very first 2006 released Intel iMacs were faster than the G5 iMacs including yours.
See this Barefeats test http://www.barefeats.com/imcd3.html
Check additional tests on Barefeats on older iMacs against newer ones http://www.barefeats.com/
The new 2010 iMacs of any sort run circles around the 2006 iMacs, so you are in for a very pleasant surprise

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

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.

How much faster or better is the new iMac... really?

Hello all,
I have a 20" 2.33Ghz C2D iMac w/256Meg video RAM, and 3Gig of RAM. I understand that many factors come in to play when you compare the over all speed of a computer. How much faster, over all, is the new iMacs over the system I have? Has anyone tested the two next to each-other yet? I am sure the new one is faster in some ways, but is it really lots faster in over all performance, or just a little?
Apple //GS

Hi Patrice,
Within Apple’s slim new 21.5- and 27-inch iMacs are NVIDIA GeForce GPUs, based on our new Kepler-class architecture, which helps make them up to 60 percent faster than last year’s models. This follows news in June that Apple’s 15-inch MacBook Pro with Retina display uses Kepler GeForce GPUs.
The new 27-inch iMac offers the GeForce GTX 660M as its base GPU, with even faster GeForce GTX 675MX or GeForce GTX 680MX GPUs available. The 21.5-inch model comes with the GeForce GT 640M GPU, with an available upgrade to the GeForce GT 650M GPU.
http://blogs.nvidia.com/2012/10/big-imac-news-less-heft-more-kepler/
So, any Apps that use the GPU to assist GPU should be much faster.
Though I don't see it listed here, it may be too new, I suspect it may be supported...

oracle.dataaccess.client not recognized in app.config for edmMapping

Hi,
I installed ODTwithODAC112030 EF provider release version.
So I want to use custom EDM Mapping for boolean or something else.
But Entity Data Model can't recognize
<oracle.dataaccess.client>
<settings>
section in appConfig file.
I'm using Win 7 x64 , VS 2010 and x86 odac components.
How can i resolve this problem.
Thank you..

Would you please do a simple test like follows?
1. create test table
create table test_table (c1 number(4) primary key not null, c2 number(1, 0), c3 number(2), c4 number(5, 0), c5 number(10, 0), c6 number(19, 0));
2. create a C# Console application and create a data model from test_table.
Because there is no custom type mapping specified in app.config, default mapping is used in the model.
Your CSDL section in Model1.edmx should show:
<EntityType Name="TEST_TABLE">
<Key>
<PropertyRef Name="C1" />
</Key>
<Property Name="C1" Type="Int16" Nullable="false" />
<Property Name="C2" Type="Int16" />
<Property Name="C3" Type="Int16" />
<Property Name="C4" Type="Int16" />
<Property Name="C5" Type="Int32" />
<Property Name="C6" Type="Int64" />
</EntityType>
3. Delete Model1.edmx.
4. Open app.config and add the following below </connectionStrings> and above </configuration>. Save changes.
<oracle.dataaccess.client>
<settings>
<add name="bool" value="edmmapping number(1, 0)" />
<add name="byte" value="edmmapping number(3, 0)" />
<add name="int16" value="edmmapping number(4, 0)" />
<add name="int32" value="edmmapping number(9, 0)" />
<add name="int64" value="edmmapping number(18, 0)" />
</settings>
</oracle.dataaccess.client>
5. Create a data model from test_table again.
The new model should be using your custom type mapping.
Your CSDL section in Model1.edmx should show:
<EntityType Name="TEST_TABLE">
<Key>
<PropertyRef Name="C1" />
</Key>
<Property Name="C1" Type="Int16" Nullable="false" />

If it does not work for you, you may want to check the version of your Oracle.DataAccess.dll in the GAC.
gacutil /l Oracle.DataAccess
Or change the timestamp of app.config.
touch.exe app.config

Oracle.DataAccess.Client.OracleDataAdapter exists in both v2 and v4

Hi there,
I am developing ASP Net application with ODP.NET 11.2.0.2.1 and VS 2010. The target framework is .Net framework 3.5 and I've explicitly Oracle.DataAccess reference to v.2, with
<add assembly="Oracle.DataAccess, Version=2.112.2.0, Culture=neutral, PublicKeyToken=89B483F429C47342"/>
, but when it compiled, it throw error
The type 'Oracle.DataAccess.Client.OracleDataAdapter' exists in both
'c:\WINDOWS\assembly\GAC_32\Oracle.DataAccess\2.112.2.0__89b483f429c47342\oracle.dataaccess.dll'
and 'c:\WINDOWS\Microsoft.NET\assembly\GAC_32\Oracle.DataAccess\v4.0_4.112.2.0__89b483f429c47342\oracle.dataaccess.dll'
c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\esptweb\df172a69\e974c60e\App_Code.eoge0t0f.4.cs
How can I fixed it?
Thanks for the help.

Did you try adding that reference using the Add Reference command in Visual Studio instead? I've never seen it behave like this before.
There are two versions of the assembly, but it shouldn't be trying to load the .net 4 version if you have a reference to the .net 2 version and you're in a 2 (or 3.5) app.

Oracle.DataAccess.Client.OracleException: ORA-1031: insufficient privileges

Hi,
I am using Visual Studio 2003. I am creating a ASP.NET Web Application NOT Windows Application.
I logged into Oracle as a DBA, but I got this message.
I wasn't sure if I missed anything when working on the Web.
Thanks for your help.

Oracle.DataAccess.Client.OracleException: The provider is not compatible

I am getting an error, and I don't understand why I'm getting it.
Error:
Oracle.DataAccess.Client.OracleException: The provider is not compatible with the version of Oracle client
Environment:
ODP.NET, 10.2.0.2 (ODTwithODAC10202.exe install)
Oracle 9i database
Windows 2000, .NET 1.x framework
Before ODP.NET, Oracle 9.2 client
Server does not have Visual Studio installed
Just installed ODP.NET today; any time I attempt to access OracleConnection, I get the error above. I am a newbie to server installations; if something is obvious to you, it might not be obvious to me, so feel free to point out even the most basic things.
I did install ODP.NET (same version) on my own PC several months ago, running over the same database, and everything seems to be working fine...

Yeah; apparently, the Oracle install on that server was known (by everyone but me, from the sounds of it) to be exceptionally fragile. Installing ODP.NET brought down all Oracle connections. Uninstalling ODP.NET broke (actually, shattered might be closer to the truth) the Oracle instance on that box. Our solution? Start from scratch with a new server. Another piece of information which would have been nice to know is that they were looking for an excuse to get rid of this server; I wouldn't have been running around like a madman trying to fix it (and stressing all the while).
So, the problem has been solved, but not in any kind of normal fashion.

How much faster is Oracle.DataAccess.Client over System.Data.OracleClient ?
