In my project, I have a database in SQL which was working fine. But now I have to make the application support oracle db too.
Some limitations I found out was that in Oracle, there is no bit field and the table name cannot be greater than 30 char. Is there any other limitation that I need to keep in mind.
I was wandering if I can make this faster. I am taking records out of Oracle and putting them into a SQL Server. btw, I am inserting into the Identity column

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.
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 need to connect to oracle database (10g) which is on differenet server.
Can i use the latest ODP.net provider or i need to use ODP.net provider related to oracle 10g only? After installing the ODP.Net what are the next steps to do in order to connect to database. This is totally new to me (connecting to oracle... i have worked with sql databases till now...)
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 RepliesWe 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?

View 1 RepliesI have to automate one database process in .Net web applicaiton which uses Oracle 11g Database as Backend.
I need to know two things:
(1) How to check space on Oracle database server? I need space on server and not in the Database itself. My process creates few tables so I want to make sure that we have sufficient space before the process starts.
(2) Also I need to create script to backup Indexes and Triggers on the table so that I can recreate them after data transfer process is completed. Any idea how to create script form c# code?
I would like to monitor all the queries running under Oracle which are being fired. Looking for some good UI tool for Oracle similar to Microsoft SQL Server Profiler.
