I have an SSAS database (Cube) that uses a DataSource with "DsTest" name, when I see the connection string properties I cannot find the server IP anywhere, Plz look at this picture :
what is this "Data Source = DsTest0" ??Where has it been defined ? There is nothing in "ODBC" list , nor in ".../etc/hosts"
I know the datasource is an Oracle database in a different server but I cannot find where the server IP is defined
It had defined in TNSNAMES.ora file in this directory :
C:\oracle\product\11.2.0\client_64\Network\admin\tnsnames.ora
you can find more information here : TNSNAMES Setup

We store a template for building SQL Server CE connection strings in our web.config and use string.format to set the data source and temp path values.
In the web.config, the template for the DB connection string is:
"Data Source={0}; Temp Path={1}; Mode=Read Only"
In the web.release.config, we use to build deployment packages, the template for the DB connection string is:
Data Source={0}; Temp Path={1}
Now we only use the SQL Server CE database for read only operations. So, being a smartypants, I thought I would remove the connection string transform in the web.release.config and just always use the read only connection string from the web.config.
This worked fine for the database I was testing. But the same code running with a different SQL Server CE database fails with the following exception:
Exception 'System.Data.SqlServerCe.SqlCeException' with message 'The
database is opened with a read-only connection. Can't perform
post-initialization operations like re-building indexes and upgrading
public tracking. Please re-open with a read-write connection. [
Database name = D:\inetpub\wwwroot\MyApp\App_Data\Storage.sdf ]'
We are using the System.Data.SqlServerCe.4.0 provider
Why in my release build that is deployed to a server does read only access fail for some SQL Server CE databases but not others? It is the same code, just pointing at a different .SDF file. The .SDF files have the same schema, just different data.
Is the driver trying to rebuild indexes because the .SDF file is in some older format? Should we never use a readonly connection in production? Is that why the original code had the transform? why do they all work with a readonly connection on my Windows 7 workstation?
You should always specify a temp path, as moving databases between OS platforms/versions can require index rebuilds.

I have problem with connecting to DBF files on remote location using OleDb.
When I use local path everything works fine.
My connection string:
string path_dbf = #"\\server\directory";
OleDbConnection conn = new OleDbConnection(#"Provider=VFPOLEDB.1;Data Source="+path_dbf+";");
I've tried to use OleDb and Odbc, but both have failed when I use remote location. I also try to use mapped directory under the OS, but it doesn't work.
I get error:
Error: Sys.Net.WebServiceFailedException: The server method 'MethodName' failed with the following error: System.Data.OleDb.OleDbException-- Invalid path or file name.
I also try to use Odbc DSN like this:
OdbcConnection conn = new OdbcConnection("dsn=MyDsnName;");
but it doesn't work. MyDsnName is Free Table directory type and it points to my mapped remote directory.
I don't have idea of any possible solution.
So I want to ask if there is a maybe some additional connection string options to do that or I do something wrong.
Thanks.
It is probably a permissions issue when running as a web app. The user which may be something like "USR_MACHINE" may not have proper permissions to the other server location and thus failing.
To confirm this, try changing your website service to "Run As" some other user that DOES have permissions, such as yourself... if STILL not a problem, then try running .net as the ADMINISTRATOR FOR CONFIRMATION PURPOSES ONLY, then revert back to the USR_MACHINE account.
Once you have confirmed, then you might want to create a somewhat restricted user so they only have access to the folder and features you want them to for security purposes.
I am attempting to configure the connection string in web.confg for an ASP.NET app to connect to Azure DB. I am new to this but am familiar with sql configuration strings to SQL Server. How do I configure the login and data source in the connection string I am building. I haven't ever dealt with the cloud like this. If my db name is DB1 how do I set the Azure path for the data source portion of the connection string. NOTE: I know where to configure it in web.config and know to create a connection object.
Thanks.
In the Azure portal, you can navigate to your database's dashboard and click 'Show connection strings' on the right side. See the first screenshot on the below tutorial:
http://azure.microsoft.com/en-us/documentation/articles/sql-database-dotnet-how-to-use/
To answer your original question, "Data Source" means the same as "Server", it is just your server name, i.e. blah.database.windows.net. All of the connection string keywords (including their synonyms) are documented here: https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring%28v=vs.110%29.aspx
How to create data base link in oracle 11 g to Access Tables.
You seem to have copied the example in the documentation without really understanding it.
The USING 'local' part of the statement is creating a link to 'the local database', where local is the service name of a database. (The example is a bit confusing, to be fair).
When the link is used it tries to interpret local as a service name, appending the current database's domain, as the docs say:
USING 'connect string'
Specify the service name of a remote database. If you specify only the
database name, then Oracle Database implicitly appends the database
domain to the connect string to create a complete service name.
Therefore, if the database domain of the remote database is different
from that of the current database, then you must specify the complete
service name.
If you're trying to create a link back into the same database - which would be a bit odd but I've seen it done in place of grant access across schemas, and that seems to be what the example is hinting at - then you can replace 'local' in the USING clause with the service name of your current database (e.g. USING 'orcl', or whatever).
You can also use a TNS alias; if your tnsnames.ora has an entry for SOME_DB which points to the SID or service name of another database, you can have USING'some_db'`. You should be able to use any connect string I think; certainly Easy Connect is allowed. There's more in the net services admin guide.
I kind of new to SQL Server, I always used access db for my sites.
I created a SQL Server on my local computer and now I want to take this db and transfer it to the server. In access all I had to do is, take the mdb file and put it on the server and change the connection string. How can I transfer the SQL Server db to the server?
Is there any file to put on the server ?
Also the connection string isn't a folder but a local computer like this:
Data Source=my-PC;Initial Catalog=storeSQL1;User ID='my-PC\com';Password='';Trusted_Connection=YES;
Who can provide me this connection string for the server (the hosting company) ?
The easiest way would probably be to create a backup of the database on your local machine, then restore that backup on the new server.
Roadmap is:
Do simple backup-restore to move user databases to target server.
Create script on source server, that can recover permissions and login-users pairing
Restore the CLR and TRUSTWORTHY security for databases, that using unsafe assemblies, simpliest way is (in proper DB):
exec sp_changedbowner 'sa' --sa just for example
ALTER DATABASE dbname SET TRUSTWORTHY ON
Enjoy
Depending on your version of SQL Server here is a good article that outlines all the ways to move a SQL Server Database.
http://blogs.msdn.com/b/sreekarm/archive/2009/09/11/move-a-database-from-one-server-to-another-server-in-sql-server-2008.aspx
As for getting the connection string yes the hosting company would provide you with that. Where is the database hosted, you could check their knowledge base articles or if it's an in house data base I'm sure a dba could provide you with that information. It won't change much from what you have but it will change.
I'm not sure what tools your using, but to start you need to do a dump or backup of your current database on your machine. After you do that then you can do and import which should create all the tables and import any data you have.
After the data exists on the server then as far as the connection string, you just need to say the Data Source is the server ip address or host name and change your User ID and Pass to match that server.
If you need more details on any part of this process, post what tools your using and what your environment looks like and I would be more than happy to assist you.
In my opinion the best way to do that is to detach the db from one server(pc), copy the files to the second one and then attach them on the second server/pc.
To detach:
USE master;
GO
EXEC sp_detach_db #dbname = N'AdventureWorks2008R2';
GO
To attach:
USE master;
GO
CREATE DATABASE MyAdventureWorks
ON (FILENAME = 'C:\MySQLServer\AdventureWorks2008R2_Data.mdf'),
(FILENAME = 'C:\MySQLServer\AdventureWorks2008R2_Log.ldf')
FOR ATTACH;
GO
