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

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.

Oracle.DataAccess.Client.OracleException ORA-06502: PL/SQL

I have the following Simple PL/SQL function:

END;
Which I am calling from the following .Net procedure:
Public Function insertTestExp(ByVal expid As Int32, ByVal Run_Identifier As String, _
ByVal Run_Complete As Boolean, ByVal CompletionStatus As String, ByVal Complete_Errors As Boolean) As Integer

Try
.ExecuteNonQuery()

End With
End Function
When I attempt to run the .Net function I get the following error:
Oracle.DataAccess.Client.OracleException ORA-06502: PL/SQL
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,

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,

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:

Is there anybody that can help me?

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).

Oracle.DataAccess.Client stored procedure ORA-01403

Microsoft announced that System.Data.OracleClient is deprecated and will be no more supported so I try to use the driver Oracle.DataAccess.Client after having installed ODP.
It works fine except for stored procedures.

The same function worked very well during several years with OracleClient !
Does any body has an idea ?

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.

Try posting this to the ODP.NET forum.
You might need to flush out the connection pool, but they can help you with that.

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.

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:

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:
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.
Exception Details: System.ArgumentException: Value does not fall within the expected range.

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.

Oracle.DataAccess.Client.OracleException - How do I look up error numbers?
