Oracle.DataAccess.Client.OracleConnection

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

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. :-(

The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw

Hi All,
I am .Net developer [.Net Fream work 2.0].
In my new windows [C#] project , I have to use oracle Database [11g] which is intalled in one of the server.
I have installed [my local mechine] odp.net and Oracle.DataAccess.dll version is 2.111.7.20.
I added reference the above dll and its working fine in my mechine.
I have build the applicatrion with release option. then i moved the release folder to QA mechine [because QA team needs to test. when the are testing , they are getting below msg
"The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw "
Please could some one can help,
whether i have to intall odp.net in QA mechine also ?
thanks
Babu

Hi,
As per my experience, Type initializer exception by ODP coulod also be due to mismatch between ODP.Net and dependant layers, especially with the service layer, which communicates with the OCI.
So, please do following:
- As suggested earlier, if not installed and then do install the ODP ship home on the target test machine.
- If already installed, ensure that versions do match, essentially you cannot pick a different ODP dll and try to make it work with a different version of ship home dlls.
thanks,
Mrinal

Oracle.DataAccess.Client.OracleConnection vs. System...

I am wondering why this code:
Dim builder As New Oracle.DataAccess.Client.OracleConnectionStringBuilder
builder.DataSource = "datasourcename"
builder.UserID = "user"
builder.Password = "pass"
Dim oraConn As Oracle.DataAccess.Client.OracleConnection = New Oracle.DataAccess.Client.OracleConnection(builder.ConnectionString)
Dim oraCMD As New Oracle.DataAccess.Client.OracleCommand("SELECT field1, field2 FROM table", oraConn)
Dim MyDA As New Oracle.DataAccess.Client.OracleDataAdapter(oraCMD)
Dim ds As New DataSet
MyDA.Fill(ds)
DataGrid1.DataSource = ds.Tables(0)
throws a "Object reference not set to an instance of an object." at the line "MyDA.Fill(ds)"
and this code runs fine:
Dim builder As New System.Data.OracleClient.OracleConnectionStringBuilder
builder.DataSource = "datasourcename"
builder.UserID = "user"
builder.Password = "pass"
Dim oraConn As System.Data.OracleClient.OracleConnection = New System.Data.OracleClient.OracleConnection(builder.ConnectionString)
Dim oraCMD As New System.Data.OracleClient.OracleCommand("SELECT field1, field2 FROM table", oraConn)
Dim MyDA As New System.Data.OracleClient.OracleDataAdapter(oraCMD)
Dim ds As New DataSet
MyDA.Fill(ds)
DataGrid1.DataSource = ds.Tables(0)
Any thoughts?

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?

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.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...
Message was edited by:

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 stored procedure ORA-01403

Hello,
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.
After calling a stored procedure that increases a value in a column I meet this error :
ORA-01403: no data found
ORA-06512: at "XXXXX.MY_FUNCTION", line 15
ORA-06512: at line 1

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

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 !

Oracle.DataAccess.Client

I am having problem using "Imports Oracle.DataAccess.Client" on my code.
When I put Imports Oracle.DataAccess.Client at the begining of the page, it will underline it and show sign of error.
When I use OracleCommand, OracleConnection, OracleDataReader on my code page, it will show underline color under them (this means something visual studio does not recognize them). I thought I already installed ODP.NEt from Oracle site. It works well with Strongly typed dataset and tableadapter for accessing oracle database through the visual studio interface and wizard.
Can anyone know what is going on with my ODP.net and Visual studio ? Please help.
thank you in advance.

Hi,
Since you are using the keyword imports, I will assume you have a VB.NET project. Simply pull down the Projects menu and choose Add Reference. Scroll to the .NET assembly Oracle.DataAccess.Client and add it to the project.

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.
2010-09-08 17:08:42,284 ERROR - Database connection lost. Oracle.DataAccess.Client.OracleException ORA-03135: connection lost contact

Has anyone come across this before? Any help will be gratefully received

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

App.config tag oracle.dataaccess.client not recognized on windows 7...

Hi all,
I have an application that is working fine on windows XP. On windows 7, the same application cannot work cause of the tag oracle.dataaccess.client you can see below which is not recognized by the system. As soon as I start the application I get an error
message
Unrecognized configuration section oracle.dataaccess.client. Can someone help please before I get nuts.

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.

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.OracleConnection
