How to set the maximum connection number in SQL Server?

The maximum number of connections for SQL Server is determined by the server’s configuration parameters. The maximum number of connections can be set in two ways:

1. Setting the maximum connection limit using SQL Server Management Studio (SSMS):
   a. Open SSMS and connect to the SQL Server instance.
   b. Right-click on the server instance and select “Properties”.
   c. In the “Server Properties” window, choose the “Connections” tab.
   d. Select the desired maximum connection number from the drop-down menu under “Maximum concurrent user connections”.
   e. Click “OK” to save the changes.
2. To adjust the maximum number of connections using Transact-SQL:
   a. Open SQL Server Management Studio (SSMS) and connect to the SQL Server instance.
   b. Open a new query window and use the following script to set the maximum connection limit:
3. Switch to the master database, enable advanced options, reconfigure the settings, set the maximum number of user connections, and reconfigure the settings.
4. Replace with the desired maximum number of connections and execute this script.

Please note that the maximum number of connections should be adjusted according to server hardware resources and application requirements. Additionally, SQL Server version and licensing restrictions should be considered to ensure the maximum number of connections does not exceed the allowed limit.
