In my web page I have written code that writes to a table in Oracle 9i. What I find is add ing or querying the table in Oracle is very slow. I tried doing the same with SQL server database and the process if 5 times faster than Oracle. In the Oracle or SQL table I have not created any indexes / primary keys, but still I find the SQL is way faster than Oracle.
Is there any way that I could improve the speed in Oracle? My table has 3 columns (PRVal, FACVal and UserID). And when the user is selected from the web page I retreive the values from the database, using a direct sql (no pl/sql stuff here, as I am new to Oracle). I use OleDBConnection, OleDbCommand and OleDbReaders classes to access Oracle data.
I have created a table in my Oracle database and am trying to add / edit / delete/ query the records. This table already has 4000000 records. Now when I try to query the database, it takes close to 3 minuetes to return records. I have tried creating indexes, but was not successfull so far.
Following is the structure:
User : varchar(20) Fac : varchar(10) Prm: varchar(100)
As the title says I have a Win 7 64 bit dev machine, Win 2K3 32 bit production box and I run against Oracle 10g which Oracle clients do I need to run? Do I need to run the Oracle 32 and 64 bit clients? And if so what versions?
I need to find a way to connect to the remote Oracle server without a DSN. There are some practical problem for accessing the server using a DSN. I need a way to connect to Oracle server like I connect to SQL Server etc. For example, in SQL server, I can connect directly with server using Servername (IP adress) + Username + Password + DB Name. Any way to connect to the Oracle server like in SQL Server we do ??
I have an Asp.net web application targeting .Net2.0 and my databse is oracle, I used SqlDataSource Control to communicate with oracle database its working fine on my development server, but on my production Oracle is 64 bit so im getting an error like
"<asp:ControlParameter doesnot have a property DbType="Int32"> " i tried with Int64 also but still im getting the same error
following is the markup of sqldatasource i used < asp:SqlDataSource ID="sdsEmployees" runat="server" ConnectionString="User Id=user;pwd=user1;server=prod" ProviderName="System.Data.OracleClient" SelectCommand="GetEmployeeInfo" SelectCommandType="StoredProcedure" OnSelecting="sdsEmployees_OnSelecting"> <SelectParameters> <asp:ControlParameter ControlID="txtNumber" DbType="Int32" /> </SelectParameters> </asp:SqlDataSource>

I am developing a web application with back end as Oracle. I call the procedures from web application when ever some update, create or delete for the records needs to be performed. How to maintain the connection in these scenarios.
Can I open the connection and maintain it through out the application till user logs out?
here's my error... Compiler Error Message: CS1502: The best overloaded method match for '_Default.InsertUpdateData(System.Data.SqlClient.SqlCommand)' has some invalid arguments
I've developed a web app in Visual Studio 2008 using ASP.NET which connects to an Oracle database and a separate SQL Server 2005 database in the same application.
I want to convert this application to use SQL Server only. I have copied the Oracle tables that I need to SQL Server and am in the process of converting the SQL queries from Oracle format to SQL Server format.
I have also modified all the Connection Strings in web.config to point to the SQL Server database now and not the Oracle one.
However I have come across a problem. The TableAdapters are configured to use the OracleClient in the declarations code behind the scenes, i.e. it is "hard coded". But this causes problems of course while modifying/saving queries, because I don't want any trace of Oracle in my new web app.
The only thing I can think of is to delete all my TableAdapters and re-create them all.
I am trying to insert NULL value in oracle database using asp.net form. and its not inserting null value check my below code and guide me what changes I have make
Dim cn As New OracleConnection("Data Source=ab; User Id=abc;Password=abc") Dim SQL As String 'build the INSERT statement Dim xy As New System.Text.StringBuilder 'Dim strDate As Date...............................
Does Oracle support mixed mode authentication Windows (active Directory) based authentication and Database authentication together. In other words can I have one application running using Oracle Authentication and one app running using Windows Authentication from the same Database? And does that Windows Authentication comes with Oracle 10g enterprise,so I don't need to purchase any special adapters or middleware?
I am currently working on the connection between ASP.NET and Oracle. I tried to search over the net and know there are many ways. Is there any 'normal practice' on which method to be used? Or it depends?
