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:
Server Error in '/src' Application.
Value does not fall within the expected range.
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.

I'd like some help on how to make the XSD compile with the new provider, Oracle.DataAccess.Client.
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.

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.

<<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. -

We support a VB.NET application which uses Oracle Data Access Components (ODAC) 10.2.0.2.21 to access an Oracle 11g database. The database is on another server, so from time to time application loses its database connection because of comms failures. To cater for this eventuality it checks for a valid connection before every database call and reopens the database if it can’t find one. This works, but subsequent database calls fail and return a System.AccessViolationException.
Here is an extract from the trace.

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,

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.

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:

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 ???

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.

The same function worked very well during several years with OracleClient !

AlanHello,
I had the solution by an other forum.
It's necessary to define the property BindByName at true.
The driver OracleClient did that by default not the driver DataAccess !

I have been reading for hours and just cant seem to make this work. I have a window app that used the ORACLEDATAACESS.dll it works great on the pc. i made the APP but when i try to redistribute i get this nasty message. I read from these forums that i should install the ODP.net net on the computer that will get the installation and i have done that but i cant see to get anywhere. Can someone please give me a tip and point out the obvious i just dont know what to do anymore. t

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.Oh interesting. I imagine there's a lot of ways that issue could crop up. Thanks!
I am driving myself completely out of my mind having tried to move a "solution" from one computer
to another. That is not a nobrainer. I ran into an issue on my home computer that defied all efforts to
stop it (the cursed varchar columns) so I decided to give up and do the development at work. But the project has not liked the
move. That is such an issue for an faq: how to design your project and whatever so that it can be
moved from one development location to another, one database to another, and then,
how to deploy it. And yeah now that you mention it differences in drive letters might well be a
factor here. :-( -
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.
JimAs 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

Hi all,
I have a .NET application which save data in an oracle database (about 2000 database read / write each day).
Every thing works fine since few years...
However, yesterday, one of my client got this error :
System.Runtime.InteropServices.SEHException: External component has thrown an exception.
at Oracle.DataAccess.Client.CThreadPool..cctor()
The type initializer for 'Oracle.DataAccess.Client.CThreadPool' threw an exception.
at Oracle.DataAccess.Client.CThreadPool.SetMaxThreads(UInt32 MaxWorkerThreads, UInt32 MaxIOCompletionThreads)
at Oracle.DataAccess.Client.OracleCommand.set_CommandTimeout(Int32 value)
Any ideas ?
Regards.Hi,
thanks for the answer. Yes the Inner exception returns "The provider is not compatible with the version of Oracle client".
Could it be the Oracle Client Version? I just noticed that on that machine there is the Oracle Client version 11.1. -
Oracle.DataAccess.Client如何处理xmltype字段
c# vs2012 windows7 oracle11g服务端客户端字符集【SIMPLIFIED CHINESE_CHINA.US7ASCII】
原本是想解决 XMLTYPE字段里面中文乱码的问题的,使用datareader里面的中文全变成“?”,
现在想用Oracle.DataAccess.Client处理xmltype字段,网上找了方法,但是会报 ORA-06553:PLS-306 的错
using Oracle.DataAccess;
using Oracle.DataAccess.Types;
using Oracle.DataAccess.Client;
string conString = "Data Source =testascii;Persist Security Info=True;User ID=common;Password=common";
XmlDocument xmlDoc = new XmlDocument();
string strProperty = @"<root>钓鱼岛是中国的</root>";
xmlDoc.LoadXml(strProperty);
Oracle.DataAccess.Client.OracleConnection con = new Oracle.DataAccess.Client.OracleConnection(conString);
con.Open();
OracleXmlType cxml = new OracleXmlType(con,strProperty);
//OracleXmlType cxml = new OracleXmlType(con, xmlDoc);
Oracle.DataAccess.Client.OracleCommand cmd = new Oracle.DataAccess.Client.OracleCommand();
cmd.Connection = con;
cmd.CommandText = @"insert into d_test values(:nvar,SYS.XMLType(:xml))";
//Oracle.DataAccess.Client.OracleParameter p1 = new Oracle.DataAccess.Client.OracleParameter("nvar",OracleDbType.NVarchar2);
//Oracle.DataAccess.Client.OracleParameter p2 = new Oracle.DataAccess.Client.OracleParameter("xml", OracleDbType.XmlType);
//p1.Value = DateTime.Now.ToLongDateString();
//p2.Value = cxml;
cmd.Parameters.Add("nvar", OracleDbType.NVarchar2).Value = DateTime.Now.ToLongDateString();
cmd.Parameters.Add("xml", OracleDbType.XmlType).Value = cxml;
//cmd.Parameters.Add(p1);
//cmd.Parameters.Add(p2);
try
int count = cmd.ExecuteNonQuery();
if (count >= 1)
MessageBox.Show("ok");
else
MessageBox.Show("shit");
catch (System.Exception ex)
MessageBox.Show(ex.Message);
con.Close();
这种写法会报 ORA-06553:PLS-306: XMLTYPE..这个错误
这个如何解决呀US7ASCII
