DataSource Controls :: The Provider Is Not Compatible With The Version Of Oracle Client?
Jan 21, 2011
I have a website in which code on the production server runs no problem. The same code on my local machine or test server produces the mess seen at the end. The exact same code. Additionally, upon trying to preview any of the table adapters in the dataset I get "DataSet1.thename could not be previewed. The provider is not compatible with the version of Oracle client"
The app is SQL Server. It always has been. It has never used Oracle. Does anyone have any insight on how to fix this? As it is now I can't do anything with my dataset. I can't edit anything in there because of this complaint about Oracle.
I am having the error stated above. The stack trace is as follows:
[Code]....
Some info's:Server: Windows Server 2008 R2
.NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
Oracle.DataAccess, Version=1.102.3.0bit
.NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1
Oracle.DataAccess, Version=1.102.3.0
My Code: OracleConnection cn; String con1 = ConfigurationManager.ConnectionStrings["myConnectionString"].ToString(); cn = new OracleConnection(); [code]....
I have checked all forums and posts regarding this error. They mention that there are 2 versions of Oracle.DataAccess.Client on the server, I only have 1 version. This runs on VS2010, but when I publish the website the error above shows up. I checked my Oracle connection from the installer and connection test passed. I tried uninstalling Oracle and reinstall, but still the same. The query above I tried changing to 'select region_code, reg_rom, ...', still the same error..
Getting the following error when browsing .net 2.0 application System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.
I have setup a .net 2.0 application with oracle backend on windows server 2008 R2. I have oracle client 11g installed on the server for the application to talk to the oracle database. This worked well when the .net 2.0 application was hosted on windows server 2003 and oracle client 10g. But when it is hosted on server 2008 with new oracle client it is giving the above error when browsing the page. This error occurs when the connection is opened inside the c# code.
We have a site that is runnig II7 64 bit with the oracle .net 64 bit provider, when I try and open this in web developer 2010 express (I'm running windows 7 pro 64bit) it says it can't load the oracle dll as its an incorrect format. I got the impress that web developer 2010 was 64bit capable.
Ofcourse this is extremly annoying as I don't get any syntax formatting for the project or intellisense.
Ultimately, we need to know if version 8.0 of the .net Sql ReportViewer control is compatible with IIS7 running in Integrated Pipeline Mode.Regardless of the countless forum posts and articles we've read and suggestions we've tried, we've been unable to get this combination to work.
We're in the process of upgrading our websites. We're having trouble with using the 8.0 version of the ReportViewer control with IIS 7 in Integrated mode. Below is a summary of our previous setup and what we're attempting to upgrade/change to.
Our previous setup:IIS 7 Classic Pipeline Mode.Net Framework 3.5 ReportViewer 8.0 Local Mode (control used within websites - no separate Sql Reporting Server)
Attempting to upgrade to IIS 7 Integrated Pipeline Mode.Net Framework 4.0 ReportViewer 8.0 Local Mode - NO CHANGE
Our sites are all working fine except for the use of the ReportViewer control. We're not ready to upgrade our reports to version 10.0 so we wanted to continue using version 8.0.
Since we're now using the Integrated pipeline mode of IIS7, we changed our root level web.config files of our websites to contain the handler for the report viewer in the system.webServer/handlers section instead of the system.web/httpHandlers section.We're receiving the following error when attempting to access a page that contains the ReportViewer control,
Microsoft.Reporting.WebForms.ReportViewerHandlerNotRegisteredException: The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add <add verb="*" path="Reserved.ReportViewerWebControl.axd" type
PublicKeyToken=b03f5f7f11d50a3a" /> to the system.web/httpHandlers section of the web.config file.We can't add the handler to the system.web/httpHandlers section of the web.config file since we're running in IIS7 Integrated Pipeline Mode.
We've tried both manually modifying the web.config file to include the handler in the system.webServer/handlers section as well as adding it via IIS. Both methods produce the same result.So, is version 8.0 of the ReportViewer control not compatible with IIS7 in Integrated Pipeline Mode? If it is compatible, what are we doing wrong? If it is not compatible, is version 9.0 of the ReportViewer control compatible?Here are the pertinent sections of our web.config files:
I have Visual Studio 2008 installed on this workstation with SQL 2000, 2005 Express, 2008 Express and I think 2008 R2 (not sure if that is a version itselve or not)
I will call that workstation HOME
I created some tables in SQLEXPRESS through VS2008.
I worked on this project on another workstation that I just installed VS2008 annd SQLEXPRESS 2008 and I know that was R2
Installed Visual Studio 2010 trial edition between the thiem I made the tables on HOME and tonight for the first time since that install
I am now getting the "cannot be opened becuase it is version Version 661. This Server supports version 655..."
What to do now?
I can opened SQLExpress 2008 management studio and it is running.
So is my SQL 2000. The problem seems to be that after the VS2010 install neither VS2008 or VS2010 can connect to the SQLExpress 2008
What do I do now?
I can't remove sql 2000 because it is tied to several 3+ gig databases that will not work in Express.
For example, many programmers prefer CAST over CONVERT because CAST is compliant with the ANSI SQL-99 standard. Does this mean if I used sql 92 compatible functions, it will work with other RDBMS such as MYSQL?
I'd like to know if there are any good EF providers for Oracle out there, and more specifically what experiences people have had with them. We're looking for a provider that is either free or paid for, but I'm struggling a bit with finding any real opinions on what the different frameworks are like to work with in a production environment.
EDIT,I should clarify that we are using Oracle 11g.
We have been really tired lately dealing with all bugs that comes out of ODP.Net and the lag time to bring out any new product out. I am looking for ado.net provider for oracle and looking for the following:
1. Entity Framework
2. Linq
3. Good support (in case we run into issues)
4. Quick response to open issues
5. Quick updates and new releases
I looked at datadirect and dotConnect by DevArt...But I am not sure if any one is better than other.
I am looking for a free linq provider for oracle. I dont need advanced features. What all I need is CRUD operations + ability to generate model from oracle db.
I would like to use this on production web site(using ASP.NET & Silverlight).
I am currently in the process of doing a feasibility study of using web parts in one of our company's intranet portal. The challenge that I am facing is that I would like to use the organization's existing oracle database as the personalization provider instead of aspnetdb sqlexpress database. I tried to looking for some sample code but we could not find any. In the MSDN, I found one article where it is using textfile as a provider, but this does not solve my purpose here. I am new to web parts. Request you to share with me some sample code to achieve this.
I am using Visual studio 2005 and Oracle 10g database.
I have a SQL Server 2008 DB with many tables filled with data and I used SQL Server Management Studio to generate a SQL dump by using the Script Wizard : Tasks -> Generate Scripts -> Script All objects in the selected database and also selecting the option to Script Data. I made sure to change the value of "Script for Server Version" to "SQL Server 2008". Then I created a new DB and ran the SQL dump on the new DB to generate an identical copy of the old DB. Then I assigned permissions to my default user to the new DB. Then I changed the connection string on my ASP.NET application to use the new DB. But when I run it, it throws the following exception -
Server Error in '/myapp' Application. The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version. 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'm deploying a small ASP.NET (framework 3.5) application in a Windows Server Web 2008 32 bits, IIS 7. The applications needs connection to an Oracle DB in another Server, using the tradicional DataAdapter, Oracle Connection, etc.
I´ve installed correctly the Oracle Client in the server (the server is another server´s client) and I´ve checked that this server has access to the server where the database is.
Even though my app isn´t able to connect to DataBase. The message says that Oracle components haven´t been found. It doesn´t find the OleDB Provider for Oracle or some dll.
¿Something I shluod know about permissions of the ASP.NEt users or something like this?
We're experiencing a nasty issue in Oracle 11g Release 2 where the w3wp process takes over and entire processor core, and debugging shows that the Oracle data provider is throwing ThreadAbortExceptions infinitely. A developer found this issue by doing the following:
1) Browse a web site that uses Oracle data connections locally (http://localhost/OracleWebSite - we use IIS, not the ASP.NET dev server, for all of our sites). This ensures that the w3wp process is running and that an active Oracle pool of connections exists in the app pool.2) Stop the web site (or perform a Rebuild All operation in Visual Studio on the web site in question).Our Oracle connection handling in the affected applications (all Oracle web apps) is well-established and robust. This issue does not occur if we disable connection pooling. This issue does not occur in Oracle 11g Release 1.
I have created my database in SQL Server 2005 Enterprise Edition and now planning to tranfer this databse to another server, But this other server is SQL Server Standard Edition, So if i try to attach my database which is created in Enterprise Edition will get sucesully connected to Standard Version ? or i will get any error message or i am doing something wrong ? This situation is fine or Version should be kept same ?
We are trying to implment some forms written in ASP.NET 2.0 and I'm trying to understand what Windows server version requirements are needed when contacting a web hosting provider etc? I see there are many versions from 1.0, 2.0, 3.5 and 4.0 which appears to be the latest version, well as far as I can see. Therefore if we sign up for hosting services and the provider only have only version 4 will this be backward compatible to support our ASP.NET 2.0 forms?
I had to restructure my database so I could synch the data between the Web and local version of my application, which I had carelessly let run amok. I finally get all the records and schema into one database but now that I've done that, my Profile system isn't working anymore. I noticed that the relationships between aspnet_Users and _Membership (and my "profile additional items table") don't exist anymore. I ran the aspnet_regsql.exe utility and registered the DB, and I'm surprised that the registration didn't re-establish the foreign key relationships, etc.
Anyway, if someone can give me pointers on how to restore these relationships or direct me to a source that explains it (i.e., what the foreign keys should be named, if there are any other aspnet_ tables that need to be linked together), I'm pretty sure this would take care of my problem. And I just noticed that nothing is in the aspnet_Profile table. Should I start all over with a new database or is this one salvageable?
We are working in a new N-Layered application with EF4 as ORM. As a requirement, we need to give support for both SQL Server and Oracle existing databases.
Our wish was to build a single EDMX model and then generate our business entities from a TT file.
The main problem was that database providers may generate different .NET types from our database field types. In this case, we'll have different EDMX models and then different auto-generated entities, which is more or less the same as have two different applications.
I don't know if we could have different SSDL files with specific database information (one for Oracle and another one for SQL Server) in separete files and share CDSL and MSL information for both databases.
Would be this solution possible?
Someone knows some other way to work with Oracle and SQL Server using EF4?
May I know in SQL Server, what is the similar syntax for %TYPE in Oracle, i.e. the variable defined will follow the data type defined in the database column?
I've got ASP.NET 4.0 application running on a 64bit OS. IIS is configured to run in 64bit mode (needs to be to support other ASP.NET applications). Is there any way to do this? Oracle doesn't provide a 64bit client as of this writing for .NET 4.0.
