SQL Server 2022 has introduced a number of new and improved startup parameters. That give you more control over the server startup process.
The most notable changes are:
- The addition of the -T1222 startup parameter, allows you to control the amount of time. That SQL Server waits for a given instance to start up before timing out.
- The addition of the -T902 startup parameter, allows you to specify how many seconds SQL Server should wait for an instance. To start up before reporting an error.
- The addition of the -C123 startup parameter, allows you to specify the maximum number of CPUs. That SQL Server can use during startup.
- The addition of the -G123 startup parameter, allows you to specify the maximum amount of memory. That SQL Server can use during startup.
- The addition of the -U123 startup parameter, allows you. To specify the maximum number of user connections that SQL Server can accept during startup.
- The addition of the -P123 startup parameter, allows you to specify. The maximum number of processor cores that SQL Server can use during startup.
- The ability to start up SQL Server using the -f switch without having to specify a trace flag. This new functionality is especially useful for those who manage large numbers of SQL Server instances.
- The ability to start up SQL Server using only a single CPU core. This new functionality can be used to reduce the overall resource utilization on a system. When starting up multiple SQL Server instances.
- The ability to start up SQL Server using a limited amount of memory. This new functionality can be used to reduce the overall resource utilization on a system. When starting up multiple SQL Server instances. Check RemoteDBA.com.
- The ability to disable the Automatic Soft NUMA Configuration option. This new option can be used to improve startup times on systems with a large number of CPU cores.
- The ability to set the maximum number of error log files that SQL Server can create. This new option can be used to prevent the creation of too many error log files, which can impact performance.
The following sections describe each of these new and improved startup parameters in detail:
T1222:
The -T1222 startup parameter allows you to control the amount of time. That SQL Server waits for a given instance to start up before timing out. By default, SQL Server will wait for an instance to start up for 60 seconds before timing out. However, if you specify a value of -1 for this parameter. SQL Server will wait indefinitely for the instance to start up.
T902:
The -T902 startup parameter allows you to specify how many seconds SQL Server. Should wait for an instance to start up before reporting an error. By default, SQL Server will wait for an instance to start up for 30 seconds before reporting an error. However, if you specify a value of -1 for this parameter. SQL Server will not report any errors and will instead wait indefinitely for the instance to start up.
C123:
The -C123 startup parameter allows you to specify the maximum number of CPUs that SQL Server can use during startup. By default, SQL Server will use all available CPUs when starting up. However, if you specify a value of 1 for this parameter. SQL Server will only use a single CPU when starting up. This can be useful on systems with a large number of CPU cores. When you want to reduce the overall resource utilization.
G123:
The -G123 startup parameter allows you to specify the maximum amount of memory. That SQL Server can use during startup. By default, SQL Server will use all available memory when starting up. However, if you specify a value of 1 for this parameter. SQL Server will only use a limited amount of memory when starting up. This can be useful on systems with multiple SQL Server instances. When you want to reduce the overall resource utilization.
Conclusion:
In conclusion, the new and improved startup parameters in SQL Server 2016 allow you to better control. The resources that SQL Server uses during startup. These parameters can be used to improve startup times, reduce resource utilization, and prevent errors from occurring. So learn the importance of startup parameters in SQL Server & try ti implement them for better results.
