Databases :: Retrieving Records From Oracle Is Slow?

Sep 29, 2010

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)

I am using the following code in VS2005:

Databases :: Add / Retrieve Is Slow In Oracle?

Jul 15, 2010

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.

Databases :: Oracle.DataAccess.Client Very Slow - How To Make It Fast

Oct 29, 2010

When I run my piece of SQL through SQL developer it takes less than half a second with an overall cost of 618 on the explain plan.

When I run the same SQL through .NET via the oracle.dataaccess.client connection it is impossibly slow taking over 5 minutes to run.

What could be causing this and what can I do?

Retrieving Data From The Database .NET MVC + Oracle

Jul 27, 2010

I have two tables Users (Userid, Name, PhoneNumber) Applications (ApplicationsId,UserId, ApplicationName, ActiveDate)

Every user will have more than 1 application.

In Nhibernate using lazy loading I can get the users data along with all the applications for every user. So, I used to do something like user.applications[i].Applicationname to get all the applications.

But, Now how do i retrieve all the applications along with the users data using oracle commands. I know how to get one application using joins. But, how do i retrieve multiple applications and store it in a IList.

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 ??

Databases :: Roles In .net / Oracle - What Is Best Practice For This

Apr 20, 2010

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?

Databases :: Migration From Oracle To Sql Server?

Feb 1, 2010

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.
