SQL Server Management Studio
Get the SQL Server edition from many instances at once by running one query through Central Management Servers (CMS) in SQL Server Management Studio.
Considerations
Section titled âConsiderationsâ- Impact on Performance: Be aware of the potential impact on network and server performance, especially with a large number of instances. It might be better to perform this operation during off-peak hours.
- Permissions: Ensure you have the necessary permissions on all SQL Server instances.
- Security: Be cautious with the authentication method and credentials used, especially if they are stored within CMS.
- Server Grouping: Use server groups to organize your servers logically (e.g., by environment, location, or application).
Setting up Central Management Servers in SSMS
Section titled âSetting up Central Management Servers in SSMSâ- Establish a Central Management Server:
- Open SSMS.
- In the âRegistered Serversâ window (View -> Registered Servers), right-click on âCentral Management Serversâ and select âNew Server Registrationâ.
- Register a SQL Server instance as the Central Management Server. This server will store the list of registered SQL Server instances and manage multi-server queries.
- Registering SQL Server Instances:
- Under the newly created Central Management Server, right-click and choose âNew Server Groupâ to create groups for organizing your servers (optional).
- Right-click on the Central Management Server or a server group, then select âNew Server Registrationâ.
- Add each SQL Server instance you want to manage. Provide the necessary connection information (server name, authentication mode, and credentials).
Executing the query across multiple servers
Section titled âExecuting the query across multiple serversâ- Connect to the Central Management Server:
- In SSMS, connect to your Central Management Server in the âRegistered Serversâ window.
- Execute a Multi-Server Query:
- Right-click on the Central Management Server or a specific server group.
- Select âNew Queryâ. This opens a query window that is connected to all registered servers within that group.
- In the query window, write your SQL script:
SELECT @@version. - Execute the query.
Viewing and exporting results
Section titled âViewing and exporting resultsâ- The results tab in the query window will show the output of the query for each server, including server names and their respective SQL Server version information.
- You can export these results to a file (like CSV or Excel) for further analysis or documentation, using the standard SSMS export options.
