I am new to SSIS. I do not have access to oracle DB. Oracle team has created a view and granted access to that view to a user which we are using to connect to DB through SSIS.
When I create a new ADO.NET connection and click on test connection ,it says connection is successful and when i try to retrieve the "tables or views" pop up box comes to enter password again and it throws error.Error : "Could not retrieve the table information for the connection manager.Object reference not set to an instance of an object"
Where as If i use the existing connection with same credentials it is working.What can be the possible reasons ?
However I used the existing connection and When I look for the view which is to be used as source, That view is not available.When I reached out to Oracle DB team who has created view , they say that the view exists and permission is granted to the user .They logged in to oracle using the same user and the user has access to the views.Now I am not sure that why is it not available to the user when I connect it through SSIS. I am using visual studio 2017
At first, you have to pick ".Net Providers\OracleClient Data Provider" from the Provider list in Connection manager for ADO.NET. Second, You should enter the name of your Oracle DB or the IP of it (The name is better) for "Server name:" drop down. Third you should enter your user and password in the textboxes below the "Log on to the database". After all of these, you can click on "Test Connection" and everything goes right. now you can click "yes" to shut the window.
Now you can add one ADO.NET source in your data flow task, pick your connection in its "ADO.NET connection manager" drop down, and finally see the tables or views list in the "Name of the table or the view" drop down.

I am trying to connect to oracle instance. I succeed in SQL developer with the same account and password, but when i try in intellij it gives me ORA-01017 Invalid Username/Password.
Also please note that i succeed in connection in SQL Developer only if i choose to connect as dba for that USER. password and account is not wrong for sure..
According to the Oracle Database JDBC Developer's Guide you have
set the internal_logon connection property to SYSDBA or SYSOPER.
IntelliJ IDEA offers this in the "Advanced" Tab
To get the properties pre-filled here, you have to select or maybe even download a driver to use. (It's offered in the "General" tab on the bottom.)
I am connecting to Oracle tables via an MS Access DB (Access 2000 format) on Win 10 (likely same issue on Win 7). My 32-bit ODBC driver is configured and is functioning. This particular Access DB is used by 2 or 3 people on a network drive.
The issue is that whenever I reopen the Access DB, the connection is 'broken' and I must reenter my password each time.
This all started to miraculously appear when I got a new computer.
Any insight is appreciated.
Looks like I solved my own issue.
What worked for me is to delete all existing linked Oracle tables within the Access DB and then re-establish the linked tables.
When the Oracle table selection box pops up, select your tables and ensure the 'save password' is selected. Confirm settings with OK and a 'save password' dialog will pop up to warn you the "..password will not be encrypted before it is saved to the file...". I was OK with this warning. Now, each time I open the Access DB, I no longer need to reenter the credentials.
In VS 2019, I created a connection in Server Explorer. The connection is for Oracle and it passed the Test and was created successfully. However, when I go to create an ADO.NET Entity Data Model, on the screen which asks "Which data connection should your application use to connect to the database?" and has a combo box immediately below that question, there are no connections from which to choose. Why doesn't my connection show up there? I even restarted Visual Studio with no difference.
I have install the Oracle Client 10.2.0 in my windows 8.1 machine. After installation this oracle client is able to connect with the database when we login in as a Administrator into the machine/pc. If we are login with the normal user into machine/pc then we are not able to connect with the database. In this scenario the oracle client application is getting close after enter username, password and database name and press button to connect into oracle client/Sqlplus to connect.
We are getting the below error after type sqlplus from the command prompt from normal user login.
SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
Thanks in advance.
For Windows 7 and up, right click on your client tool and Run as Administrator.
I found this solution and fix this issue from the below steps.
Assign the "Create global objects" user right to the non-Administrator account.
1. Click Start, point to Programs, point to Administrative Tools, and then click Local Security Policy.
2. Expand Local Policies, and then click User Rights Assignment.
3. In the right pane, double-click Create global objects.
4. In the Local Security Policy Setting dialog box, click Add.
5. In the Select Users or Group dialog box, click the user account that you want to add, click Add, and then click OK.
6. Click OK.
I have a web site developed locally with a local Sql Server database. I also have a web host that provides one Sql Server database for my site. Now I want to deploy the application, and I would like to be able to manage the remote database from the Server Explorer in Visual Studio. I have the connection string used in the application, which works fine for adding, say, a datasource to a control etc. But I don't know if there's any way to use it to connect the database inside the Server Explorer so that I can add tables etc. I have read that you're supposed to be able to this instead of using the Sql Server Management Studio, but I have'nt read anything about how to connect to the remote database in it.
What I have tried so far is this: I have selected Add database in Server Explorer. This brings up first a dialog where I choose Sql Server. And then I get a dialog where I can set Server name (which I tried using the ip address in the connection string below), and Authentication (where I chose Sql Server Authentication, with the user id and password from below). But when I test the connection it fails.
Here's the connection string, which works fine when used for datasources in the application (obviously with different user name and password):
Any help appreciated!
EDIT:
Well, I've done everything suggested by lewiguez below now, but it doesn't make any difference. I can't believe this should be so hard... I keep getting this error message in Sql Server Management Studio:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
Here's the process I follow for working with remote databases:
In VS 2008 under the Server
Explorer tab, right-click on "Data
Connections" and then click "Add
Connection"
Change the Data Source to
"Microsoft Sql Server"
Put in your fully-qualified
"Server Name" (be it IP Address, domain name, etc.), select "Sql Server
Authentication" and put in "User
Name" and "Password" for the database user
Select the database you want to connect to under "Select or enter a database name"
Hit "Test Connection" to test and then "OK" to accept
You should be able to interact with the database at this point by expanding the connection and then the "Tables" folder. For example, right-click on the Tables folder and you'll be presented with an "Add Table" option in the dialog. Right-clicking an existing table will bring up the "Open Table Definition" options where you can change any columns, etc.
If you're not getting to this point (and it sounds like you're not), I'd recommend checking your Sql Server connection from whatever machine you're using.
I generally do this by going into the Management Studio and connect with whatever credentials I'm trying to use. If they don't work, make sure they are, in fact, added as a Sql Server user and a database user (they have to be both).
Also, I would check in the Sql Server Surface Area Configuration Manager. You have to allow TCP connections and you have to be set up to allow Sql Server Authentication connections as well from remote hosts. If THAT'S all set up, but you still can't connect, I'd double-check to make sure your firewall is allowing Sql Server connections. The default port is 1433.
Also, if you can connect, but then can't write to anything, double-check your table permissions. Hope this helps!
I finally understood the problem: as I suspected the settings in my own installation was not the problem, but rather it was the settings on the Sql Server installation on my web host. And in fact I found a place in the control panel on my web host where I could set an exception to my ip address so that my ip would be granted access to the port 1433 for Sql Server, which is otherwise closed by default for security reasons.
I've had no luck finding any information about this at all on the internet, which I find strange. All the information I could find had to do with changing these settings on your own local installation of Sql Server. But I'm sure there are loads of people out there who like me use a web host for deploying their web site, and then that info doesn't seem to apply. (Perhaps apart from the TCP setting, which I think must be set, and there's detailed info about that here: http://www.linglom.com/2009/03/28/enable-remote-connection-on-sql-server-2008-express/ )
Hope this helps someone else who like me uses a web host. Now everything works fine for me at least, both in Management Studio and in Visual Studio Server Explorer.
