Databases :: Connecting To Oracle In A Web Application?
Feb 21, 2011
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?
In my asp.net application im using Oracle client. In the connection string, we specify the 3 basic attributes: data source, User Id, and Password. We are using connection pooling. Our data resides in 2 different Oracle schemas. Most of the requests are for data from both Schema1 and Schema2.
Is it possible that the connections are implicitly tied to a schema1 or schema2?
My Application uses two SQL databses, one for membership/roles (ASPNETDB.MDF) the other for my data. When deploying to a server do I have to use two connection strings, one for each database? I am using the publish to provider wizard with VWD 2008 to replicate the databases on Sqlserver 2008 (Windows server 2008 R2). I have my data connection working fine, I am just trying to get mebership and roles working.
I am supposed to develop an enterprise-class ASP.NET Web Application that connects to multiple databases. For example when the web form loads, I should populate different ASP.NET controls (GridView, DataPager, TextBox, DropdownList etc) from multiple databases (SQL Server, Oracle, DB2, SAP Server etc) and also, edit the data in the controls and save the data to the respective databases on button submit.
Should I use Web Service or WCF for data integration, if so is there a limit on the size of the data?
What should be the architecture considering the application should be scalable and easy to maintain?
I am developing an web application using csharp and oracle as database. I have table with columns like below. How can I ensure that sql selects from one table column but it shows two columns depending weather it is Debit or credit. How can I come up with something Statement of Account ?
Number Amount Type
2 6000 Dr
3 4500 Cr
4 2300 Dr
5 1200 Dr
6 1300 Cr
Now I want the sql out put to be as below. How can I achieve?
I have created an SSIS package to fetch the details from an Oracle database and import the details in to SQL servers table. In development region the client provided the connection description for oracle server as shown below: Using the above string I have selected Microsoft OLE DB provider for Oracle and gave xxxxx:1543/AU1D as server name and provided the username and password. It got connected successfully. (DESCRIPTION = (ADDRESS_LIST =(ADDRESS = (PROTOCOL = TCP)(HOST = xxxxx.abc.XYZ.com)(PORT = 1543)) )(CONNECT_DATA = (SERVER=dedicated) (SID=AU1D) )) For Prod environment the Oracle servers connection description is: C10P =(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = yyyyy.abc.XYZ.com)(PORT = 1524)) (ADDRESS = (PROTOCOL = TCP)(HOST = zzzzz.abc.XYZ.com)(PORT = 1524)) (ADDRESS = (PROTOCOL = TCP)(HOST = vvvvv.abc.XYZ.com)(PORT = 1524)) (LOAD_BALANCE = yes)(CONNECT_DATA =(SERVICE_NAME = C10P. abc. XYZ.com)(FAILOVER_MODE=(TYPE=SELECT)(METHOD=BASIC)))) Now I don't have the SID to use in the connection.
I am fetching data from oracle data base in asp.net application. To achieve this functionality i have used Oracle.DataAccess dll . In my developement enviorment it working fine.
But once I deployed this code on IIS 6.0 it is stopped working and I checked my log and found connection not get established . Then I make sure Oracle.DataAccess.dll present in to bin folder also I try to put this dll in side GAC, but still my code is not working on deployed server.
I already have an existing sdf file that is used in a windows application by looking at the current programs folder to find it. I want to use this same database (a copy of it) on an ASP .Net website so won't be hosted in a sql server anywhere want's to be accessed directly, is this possible?
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 doing cmd.ExecuteNonQuery();I am able to get the number and varchar2 values from output parameters. But i am unable to get output from Ref Cursor. (How can i get this...)If i use dataadaptor then i am getting the datatable in the dataset(but i am not getting the other two parameters(where will get the other two??)...
