In SQL server we are using sp_configure from very long time but many of DBA's are still seems confused about parameters like does this parameter require reboot or "Reconfigure with over ride is enough". This question clicks during interviews or client meetings only which makes it worth knowing.
SQL server has a table which keeps this info handy for all DBA's and table is "sys.configurations". In this table there is a specific column is_dynamic if its value is 1, The variable that takes effect when the RECONFIGURE statement is executed. If this value is 0 we have to restart SQL Server.
select name as Configuration_Option,
Case is_dynamic
when 1 Then 'Reconfigure with override'
ELSE 'Please Restart SQL Services' END as [Reboot?]
from sys.configurations
Below is List of options require Reboot
