How to: Create, Delete, or Modify a Shared Data Source (Report Manager)
A shared data source specifies connection properties for a data source. If you have a data source that is used by a large number of reports, models, or data-driven subscriptions, consider creating a shared data source to eliminate the overhead of having to maintain the same connection information in multiple places.
The following icon indicates a shared data source in the Report Manager folder hierarchy:
To create a shared data source
In Report Manager, navigate to the Contents page.
Click New Data Source. The New Data Source page opens.
Type a name for the item. A name must contain at least one character. It can also include spaces and certain symbols, but not the characters ; ? : @ & = + , $ / * < > | " /.
Optionally type a description to provide users with information about the connection. This description will appear on the Contents page in Report Manager.
In the Connection Type list, specify the data processing extension that is used to process data from the data source.
For Connection String, specify the connection string that the report server uses to connect to the data source. It is recommended that you do not specify credentials in the connection string.
The following example illustrates a connection string for connecting to the local SQL Server AdventureWorks database:
data source=<localservername>; initial catalog=AdventureWorks
For Connect using, specify how credentials are obtained when the report runs:
If you want to prompt the user for a logon name and password, click Credentials supplied by the user running the report.
If you intend to use the data source with reports that support subscriptions or other scheduled operations (such as automated report history generation), click Credentials stored securely in the report server.
If you want the report server to pass the credentials of the user accessing the report to the server hosting the external data source, click Windows Integrated Security. In this case, the user is not prompted to type a user name or password.
If the data source does not use credentials (for example, if the data source is an XML file that is accessed from the file system), click Credentials are not required. You should only specify this credential type if it is valid for the data source. If you select this option for a data source that requires authentication, the connection will fail. If you select this option, be sure to configure the unattended execution account that allows the report server to connect to other computers to retrieve data or files when user credentials are not available.
For more information about configuring credentials, see Specifying Credential and Connection Information for Report Data Sources. For more information about the unattended execution account, see Configuring the Unattended Execution Account.
