Oracle.DataAccess.Client.OracleException

Hi,
I am trying to cennect to our oracle database 8i using ODP.Net.
When I run my code I get the following Exception:
Oracle.DataAccess.Client.OracleException ?alc\7.0.3300.0__b03f5f7f11d50a3a\microsoft.visualc.dll at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, IntPtr opsSqlCtx, Object src, String procedure, String[] args) at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, Object src, String[] args) at Oracle.DataAccess.Client.OracleConnection.Open() at WebApplication88.WebForm1.Page_Load(Object sender, EventArgs e) in c:\inetpub\wwwroot\webapplication88\webform1.aspx.cs:line 30
I get said exception when I try to open the connection.
Here is my code:
try
OracleConnection conn;
conn = new OracleConnection();
conn.ConnectionString = "User Id=xxx;Password=yyy;Data Source=zzz";
conn.Open();
conn.Close();
catch(Exception ex)
Response.Write(ex.ToString());
All help greatly Appreciated,
yevy

Exact same thing happens for me, but no one here seems to want to help!
I'm wondering if their ODP.NET stuff even works at all!

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.

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,

Versions:
Client:          Oracle10g Data Provider for .NET 10.1.0.2.0

Vitor,
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.OracleException not compatible version

Hi,
i have installed the oracle developer tools for VS2005.NET. In my programms i put a reference to the Oracle.DataAccess.dll Version 2.102.2.20 in my Project. I can start and run this Programm on the same PC without problems.
If i copy the Programm-Exe and the Oracle.DataAccess.dll on an other PC and start this Programm there, i became a Error-Message:
"Unbehandelte Ausnahme: System.TypeInitializationException: Der Typeninitialisier

Is there anybody that can help me?
thanks,

You need to run the installer to install ODP.NET on the target machine. Simply copying a few files is not good enough (at least not until we support xcopy instant client).

I have determined by trial and error that the problem is in passing the VARCHAR2 parameters. I do not have this problem with the Microsoft Oracle Provider. Can someone help me with what I'm missing? Thanks.

Note that I have not tested your code... but, it looks like you are using bind by position (which is the default). In this mode the return value needs to be bound first since ODP.NET will generate code similar to this:
:ret_val := proc(:1, :2,...);That's where I would start anyway.
Hope that helps a bit,

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

Hello,
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 !

System.AccessViolationException from Oracle.DataAccess.Client.OpsSql.Execut

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.

Since this is an oracle section, I think you'll get more help over at the oracle forums.

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.

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" />
<Property Name="C2" Type="Boolean" />
<Property Name="C3" Type="Byte" />
<Property Name="C4" Type="Int32" />
<Property Name="C5" Type="Int64" />
<Property Name="C6" Type="Decimal" Precision="19" Scale="0" />
</EntityType>
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.
