Script to check SQL Server Linked Server Status

 

It leverages on the system stored procedure sys.sp_testlinkedserver

SET NOCOUNT ON; DECLARE @LinkName NVARCHAR (128), @retval INT, @msg varchar(300) IF (SELECT COUNT (srvname) FROM sys.sysservers WHERE srvname <> @@SERVERNAME) = 0 RETURN DECLARE srvname INSENSITIVE CURSOR FOR         (SELECT srvname FROM sys.sysservers WHERE srvname <> @@SERVERNAME) FOR READ ONLY OPEN srvname     FETCH NEXT FROM srvname INTO @LinkName WHILE @@FETCH_STATUS = 0 BEGIN     BEGIN TRY         EXEC @retval = sys.sp_testlinkedserver @LinkName     END TRY         BEGIN CATCH         IF @LinkName IS NULL RETURN         SET @retval = SIGN(@@ERROR)         IF @retval <> 0         BEGIN           SET @msg = 'Unable to connect to the Linked server : ' + @LinkName           RAISERROR (@msg, 16, 2 )         END     END CATCH     FETCH NEXT FROM srvname INTO @LinkName     END        CLOSE srvname DEALLOCATE srvname

Testing a Connection from Client to SQL Server using UDL

A connection from client to SQL Server can easily be checked with the help of a .udl file. This is also helpful for building a connection string.

Step 1 - Create a .udl file
Create a text file and name it for example test.udl
Double click on test.udl to open the connection dialog.

Step 2 - Choose the type of connection
Go to the first tab “Provider”
Choose “Microsoft OLE DB Provider for SQL Server” or any other provider according to your needs.

Step 3 - Set up connection properties
Go to the second tab “Connection”, choose the server, enter username/password and choose a database from the drop down list.

Step 4 - Connection String
Once you click on “OK” a connection string based on your connection settings is written to test.udl. After you open test.udl you will find a connection string like this.

[oledb]; Everything after this line is an OLE DB initstringProvider=SQLOLEDB.1;Password=wrf%32g;Persist Security Info=True;User ID=siva;Initial Catalog=msdb;Data Source=SQLTEST

Connetion to SSIS from client computer failed

Consider the following scenario. A server is running Microsoft SQL Server 2005 Integration Services (SSIS). From a client computer, you use SQL Server Management Studio to connect to Integration Services on the server. To connect to Integration Services on the server, you use a user account that is not a member of the Administrators group on the server. In this scenario, you receive the following error message:

Cannot connect to SSISServer
Additional information: Failed to retrieve data for this request (Microsoft.SqlServer.SmoEnum)
Connect to SSIS Service on machine "SSISServer" failed: Access is denied.
