View 1 RepliesI 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'm using oracle for my asp.net website. In website I have 3 different roles. Now do I need to create as many diff users in oracle as roles?
Someone in team insisted on having as many users in oracle. But then unnecessarily i have to maintain multiple connection strings in app.
like, I have manager/ team leader/ user roles.
Now the team member insists on having 3 users in oracle. then in DAL i've to check role and use corresponding connection string.
This is not very big app, but in all 12-15 aspx pages and some 10 table in oracle to be used only on intranet.
what is best practice for this?
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 need to transfer SQL Server databse to Oracle database.
View 2 RepliesIn 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.
