Cast 'ManagedDataAccess.Client' to 'DataAccess.Client'
I get the error "Unable to cast object of type 'Oracle.ManagedDataAccess.Client.OracleConnection' to type 'Oracle.DataAccess.Client.OracleConnection'." when try to do something like
EntityConnectionStringBuilder myConn = new EntityConnectionStringBuilder();
myConn.Provider = "Oracle.ManagedDataAccess.Client";
myConn.ProviderConnectionString = "user id=****;password=*****;DATA SOURCE=****:1521/****";
myConn.Metadata = @"res://*/Model1.csdl|
res://*/Model1.ssdl|
res://*/Model1.msl";
new Entities1(myConn.ToString());
Suggestions?
If you have an .edmx model, there's a reference in it to Oracle.DataAccess near the top. You need to change that to Oracle.ManagedDataAccess in order to use the managed client with it.

I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC). First of all, it works fine as long as the connection string is inside the App.Config file. But when I try to build it dynamically in the C# code (or rather, statically at the moment) it fails. I have it working with a dynamically built connection string when doing Model from Database though, so I'm at a loss right now.
First, I have created a second constructor for the context class that takes a string and does base(connectionString). Then I build the connection string via
OracleConnectionStringBuilder oracleBuilder = new OracleConnectionStringBuilder();
oracleBuilder.DataSource = "TEST.BLA.COM";
oracleBuilder.UserID = "ABC";
oracleBuilder.Password = "abc";
oracleBuilder.PersistSecurityInfo = true;
string connection = oracleBuilder.ToStrin();
Now trying to open an EntityConnection by giving to it this provider-specific connection string (or even the static one from the App.Config) doesn't work; I get "keyword not supported: user id"). Trying it by creating a context and giving this connection string doesn't work either. I'm pretty sure that this is because I didn't specify the provider to use; after all, it should use the Oracle.ManagedDataAccess.Client provider and not an SQL Server based one.
I then tried to get around this by using an EntityConnectionStringBuilder on top and specifying the provider keyword there, but then I get "keyword not supported: provider" when using it in the context constructor, and "the 'metadata' keyword is always required" when using it with the EntityConnection constructor.
As I said above: I bet it's the provider that I have to specify somehow, but I don't know how. The code that does work is the following:
using (var context = new Model())
context.Database.Connection.Open();
context.Database.Connection.Close();
When I read context.Database.Connection.ConnectionString, it is exactly the provider-specific connection string I created above, but I don't know where to specify the provider again. Do you know of any way to do this? Certainly there must be one.
PS: I have also posted this question on http://stackoverflow.com/questions/27979454/ef-code-first-from-database-with-managed-oracle-data-access-dynamic-connection because it is quite urgent and I'd like to use Code First from Database. Otherwise I'd have to go "back" to using Model from Database again, which is not ideal because we have updatable views where the .edmx-file has to be edited after every reload of the model, while with Code First from DB inserting into the view automatically works.I am trying to use the relatively new Code First from Database with the newest EF (6.x) and on an Oracle database (11g, but I have installed the newest ODTwithODAC).

Oracle.ManagedDataAccess.Client Operating System Authentication
Hi.
I am trying to get OSA to work with Oracle.ManagedDataAccess.Client, is this not supported?
I get the following Error: ORA-01017: invalid username/password; logon denied
Here are some of the variations of connection string, I have been testing with.
Data Source=BLA.BLA.COM;
Data Source=BLA.BLA.COM;User Id=/;
Data Source=BLA.BLA.COM;Integraded Security=SSPI;
Data Source=BLA.BLA.COM;Trusted Connection=True;
Data Source=BLA.BLA.COM;User Id=/;Integraded Security=SSPI;
Data Source=BLA.BLA.COM;User Id=/;Trusted Connection=True;
Integrated Security and Trusted Connection gives me, unknown or illegal connection string attribute errors.
My first assumption would be that my Operating System Account doesn't have access to the Oracle Database I am trying to log on to.
But I am fully capable of connecting to the database with OSA with sqlplus, sqldeveloper and toad.
Can somebody explain to me why this isn't working? And what I may do to fix it?
It may be worth mentioning that I am trying to use the 12c x86 ODP.NET Managed Provider, against 11g/11.2 Oracle Databases.That's correct. Kerberos is not currently supported by managed ODP.NET. We are working to support this feature, but don't have an ETA on when it will be available.
What company or organization is requesting this feature?
I believe there's an open feature request for Kerberos support in the Oracle .NET Feature Request Tool. Fee free to add your vote to this request. -

Bug: in ManagedDataAccess while fetch from "Select .., NULL, ... From dual"
Hi,
I have the problem with the new managed ODP.Net driver.
If I fetch data from a select which has column with a fixed value "NULL" the driver decides after a certain amount of data that the value is not null any more. Which causes a lot of problems especially if you try to hide not needed blob data.
The Problem somehow depends on the FetchSize of the command. It seems like the error occurs if more than one db round trip to fetch the result is necessary.
System: Windows 7 64 Bit
Platform: .net 4.0 x86
database: 11g Release 11.2.0.3.0 - 64bit Production
Oracle.ManagedDataAccess Version: 4.112.350
I created a small example to reproduce the problem.
Thanks for your help

Edited by: user540519 on 19.12.2012 13:50Hello
I ran the testcase here and reproduced the issue on 32 bit unmanaged beta v4.0.30319
note: same testcase works with Oracle.DataAccess (but not with managed).
This appears to match unpublished defect Bug 14666093 and is meant to be fixed in a later beta release.
Some things I noticed when testing
with the default fetchsize the breaking point is 67 iterations.
e.g.
private static int _intPara = 66; // Works
private static int _intPara = 67; // Fails
If I increase the fetchsize then it breaks at different values as you noticed..
Hope this helps.
Kind Regards

Using CASE and CAST in a INSERT statment
Can I have a CASE condition or a CAST condition within an INSERT statement?
For example:
Insert into table1 (
Value1,
Value2,
Value3,
Value4)
Select
Seq1.nextval,
Case when (color.grade in (6,5,7,8) or color.grade2 in (6,5,7,8,11,12)
Then 2
Else 1
End case,
‘GREAT’,
CAST(color.client as varchar2)
From color;
Must I specify a column name in the CASE statement? If so, how can I do it if it is based on values from 2 columns?Satyaki_De wrote:
Yes.
A little modification in your query ->
Insert into table1(
Value1,
Value2,
Value3,
Value4
Select Seq1.nextval Value1,
Case
when color.grade in (6,5,7,8)
or color.grade2 in (6,5,7,8,11,12) Then
2
Else
1
End case Value2,
‘GREAT’ Value3,
CAST(color.client as varchar2) Value4
From color;Regards.
Satyaki De.I don't think that the "END CASE" is supported in SQL, it's the PL/SQL syntax of the CASE statement that requires an END CASE.
In addition if you cast to VARCHAR2 you need to specify the length of the VARCHAR2, e.g. VARCHAR2(100).
So the statement probably should look something like this (untested):
Insert into table1(
Value1,
Value2,
Value3,
Value4
Select Seq1.nextval Value1,
Case
when color.grade in (6,5,7,8)
or color.grade2 in (6,5,7,8,11,12)
Then
2
Else
1
End Value2,
'GREAT' Value3,
CAST(color.client as varchar2(100)) Value4
From color;Regards,

As ORA-12537 after change to Oracle.ManagedDataAcess.dll mentioned, it works without any problem with the unmanaged library.Please advice, thx. -
ManagedDataAccess OracleConnection.close is extremely slow
In a vb.net app we use Oracle.ManagedDataAccess.dll (version version 4.112.3.50) to read 1000s of records of a ResultSet. Once the records are read and processed, we call connection.close() which takes 15 minutes or more to complete. The more records read the longer the close takes.
Any insights into what might be causing the slowness would be greatly appreciated.
This is a minimized code example:
dbcon = New OracleConnection()
dbcon.Open()
cmd = New OracleCommand(sqlString, dbcon)
reader OracleDataReader = cmd.ExecuteReader(CommandBehavior.SingleResult)
While (reader.Read())
'consume and process record
End While
reader.Dispose()
cmd.Dispose()
dbcon.Dispose()
thank you,
StephenAre you saying that the the Con.Close call itself takes 15 minutes? Or are you just stating the entire operation takes 15 minutes?
How big are the records you're fetching, and what are the data types?
I just tested the following, and total elapsed time was ~62 seconds. That was against a remote database that is rather slow though. Just for grins, I then ran it with against my local database, and elapsed time was ~3 seconds.
It may be worth having your network guys look into the behavior to see if it may be just a slow network issue.

Oracle.ManagedDataAccess raise ORA-03135: Connection lost contact
Hi,
I am trying to connect to Oracle RAC using Oracle.ManagedDataAccess.dll 4.121.2.0 (latest release)
All instances fail to run and raise the exception OracleInternal.Network.NetworkException (0x80004005): ORA-03135: Connection lost contact ---> System.Net.Sockets.SocketException (0x80004005): An established connection was aborted by the software in your host machine
Except one instance it works fine…, I want to know what is the difference that made it run…, also I was able to connect using the unmanaged driver and the old driver and using sqlplus..
The DBA sees the connection with this error:

Do you have a sample reproducing the issue?
I've tried the following simple test and I do not see any exceptions.
NOTE: I've enabled all exception types by selecting Debug -> Exceptions... from the menu and then executed the test from VS2012.
Regards,

ManagedDataAccess wants TNS listener
Hi all;
I am trying to connect using the connection string: "USER ID=hr;PASSWORD=hr;DATA SOURCE=mercury:1521/XE"
My connector class is: "Oracle.ManagedDataAccess.Client" which I believe is the connector that does not require the Oracle fat client to be installed.
And I am getting the error:
Oracle.ManagedDataAccess.Client.OracleException occurred

Any idea why?
thanks - daveWhile you only need to install the connector (ODP.NET, Managed Driver), you still need to configure Oracle DB server networking access. This requires setting up some configuration files or placing the configuration info in a .NET config file.
Networking is generally done through TNS, Easy Connect, or LDAP.
You can put the TNS or Easy Connect info right into the Data Source attribute of the connection string as well. -
Oracle.ManagedDataAccess - ora-12537
Hi,
I have problems with .net 4.0 WPF application. Everything working ok on developer machine and on tests virtual machines. I have just problem on one laptop. I tried different approaches but nothing helping.
I'm using connection string like:
string conn = ser Id=secret_user;Password=secret_password;Data Source=" +
"(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.7.46)" +
"(PORT=1523))(CONNECT_DATA=(SERVER=dedicated)(SERVICE_NAME=HDPROD)))";
or publishing app with tnsnames.ora and sqlnet.ora files and using connections strings like:
string conn = "User Id=secret_user;Password=secret_password;Data Source=HDPROD"
And everything is ok on my developer pc, test virtual machines, but im keep getting error: ora-12537 on one of laptops.
Any ways to fix it?
Regards,
Bart.I added following settings in app.config file
<configSections>
<section name="oracle.manageddataaccess.client" type="OracleInternal.Common.ODPMSectionHandler, Oracle.ManagedDataAccess" />
</configSections>
<oracle.manageddataaccess.client>
<version number="*">
<settings>
<setting name="SQLNET.AUTHENTICATION_SERVICES" value="all"/>
<setting name="NAMES.DIRECTORY_PATH" value="ezconnect"/>
</settings>
</version>
</oracle.manageddataaccess.client>
Still failed, sometimes it throws "ORA-12537: Network Session: End of file", sometimes throws "ORA-03135: Connection lost contact".
As ORA-12537 after change to Oracle.ManagedDataAcess.dll mentioned, it works without any problem with the unmanaged library.Please advice, thx. -
Edmx cannot mapped stored procedure column info not displaying
Hi,
I'm trying to follow the QBE on how to mapped stored proedure in EF.
Everything works fine until I need to Add Import Function where I could not see the list of column info.
I'm using .NET 4.5, EF 5.0, 11gR3 DB, VS 2012 & ODP 11.2.0.3.60 (beta)
Below is my app.config.
<oracle.dataaccess.client>
<settings>
<add name="HR.UPDATE_AND_RETURN_SALARY.RefCursor.NEW_SALARY" value="implicitRefCursor bindinfo='mode=Output'" />
<add name="HR.UPDATE_AND_RETURN_SALARY.RefCursorMetaData.NEW_SALARY.Column.0" value="implicitRefCursor metadata='ColumnName=FIRST_NAME;BaseColumnName=FIRST_NAME;BaseSchemaName=HR;BaseTableName=EMPLOYEES;NATIVEDATATYPE=Varchar2;ProviderType=Varchar2'" />
<add name="HR.UPDATE_AND_RETURN_SALARY.RefCursorMetaData.NEW_SALARY.Column.1" value="implicitRefCursor metadata='ColumnName=SALARY;NATIVEDATATYPE=Number;ProviderType=Int32'" />
</settings>
</oracle.dataaccess.client>
As far as I can tell it seems like VS would use the tags above to figure out the return column info and create a complex type. I could not see why it is not recognizing it.
Please note that I can access an Oracle table successfully and display rows in VS.
Thanks in advanceI'm not sure if you're the person that just logged a SR on this, but I just recently worked the same issue.
It turns out that
a) if you don't pay attention, adding a new Oracle Connection in Server Explorer defaults to the MANAGED ODP.NET (you can still create a connection using UnManaged though).
b) the metadata for MANAGED ODP.NET is different than the metadata for UNManaged. Here's the correct mapping for MANAGED ODP:
oracle.manageddataaccess.client>
<version number="*">
<implicitRefCursor>
<storedProcedure schema="HR" name="UPDATE_AND_RETURN_SALARY">
<refCursor name="NEW_SALARY">
<bindInfo mode="Output" />
<metadata columnOrdinal="0" columnName="FIRST_NAME" providerType="Varchar2" nativeDataType="Varchar2" />
<metadata columnOrdinal="1" columnName="SALARY" providerType="Double" nativeDataType="Number" />
</refCursor>
</storedProcedure>
</implicitRefCursor>
</version>

Sql server edmx to oracle edmx converstion
in my project i migrate Edmx from sql to oracle: for this i did generated scripts from sql server to oracle using Database script generation in entity framework. In this i got number datatype for boolean,bit datatypes when i place this code

<add name="byte" precision="2" />
<add name="int16" precision="5" />
</edmMapping>
</edmMappings>
</version>
</oracle.manageddataaccess.client>
worked properly but when i am adding new table to edmx the existing mapping details in msdl are lost why?Kelly,
The OMWB only supports inline data transfer of image types to LONG RAW via SQL*Loader.
You should be ablr to use TO_LOB() to convert the LONG to LOB.
The error you have is what you get when you try yo migrate to BLOB. TO use SQL*Loader
with BLOB you would need to have unload each image into a seperate file and the OMWB
doen't help you do this. bcp dumps the image data in hex (hence the HEXTORAW sql function),
I don't know how bcp would dump this as binary.

Managed ODP: InvalidCastException when returning large number
I get an InvalidCastException "Specified cast is not valid" when trying to get a value bigger than Decimal.MaxValue as a scalar result from a select.
From the stack trace and inspection of the Oracle.ManagedDataAccess.dll code I would expect OracleDataReader to cast to OracleDecimal (or System.Numerics.BigInteger) instead of System.Decimal for large numbers.
Is this a bug?
Stack trace:
at Oracle.ManagedDataAccess.Client.OracleDataReader.GetDecimal(Int32 i)
at Oracle.ManagedDataAccess.Client.OracleDataReader.GetValue(Int32 i)
at Oracle.ManagedDataAccess.Client.OracleCommand.ExecuteScalar()
at Cora.Data.DBProvider.Tests.CoraParameterTest.BigIntegerOracleTest() in D:\svnroot\tech\lib\Cora.Data.DBProvider\Cora.Data.DBProvider.Tests\CoraParameterTest.cs:line 98
How to reproduce:
- create a table NUNITTEST_PARAM_SIMPLE with a column BIG of type NUMBER(38)
- run sample code
using ( OracleConnection conn = new OracleConnection(ORACONN) )
conn.Open();
using ( OracleCommand cmd = conn.CreateCommand() )
cmd.CommandText = "insert into NUNITTEST_PARAM_SIMPLE (BIG) values (1234567890123456789012345678901234567)";
cmd.ExecuteNonQuery();
using ( OracleCommand cmd = conn.CreateCommand() )
cmd.CommandText = "select BIG from NUNITTEST_PARAM_SIMPLE";
object result = cmd.ExecuteScalar(); // Exception
conn.Close();There is no safe type mapping for ExecuteScalar. It's an uncommon use case.
Even if there was, making the correct conversion implicitly would lead to more work for the application developer. Let's assume ODP.NET performs the "right" conversion. Now, the app needs to manipulate the data. What data type does it treat the returned value as: string or decimal? It could be either. That means twice as much code. One set deals with the data if a decimal was returned. The second deals with the data if a string is returned.
It would be much easier to write code for one scenario, rather than two. That is why ODP.NET safe type mapping is an explicit conversion the developer makes.
