This includes actions such as starting and stopping the service, or configuring startup options.ĭescribes how to perform server network configuration tasks such as enabling protocols, modifying the port or pipe used by a protocol, configuring encryption, configuring the SQL Server Browser service, exposing or hiding the SQL Server Database Engine on the network, and registering the Server Principal Name.ĭescribes how to perform client network configuration tasks such as configuring client protocols and creating or deleting a Server Alias.ĭescribes the SQL Server Management Studio editors that can be used to design, debug, and run scripts such as Transact-SQL scripts. Logon triggers support actions such as logging connection activity, or restricting logins based on logic in addition to the credential authentication performed by Windows and SQL Server.ĭescribes how to manage the service associated with an instance of the Database Engine. Collations define the bit patterns used to represent characters, and associated behaviors such as sorting, and case or accent sensitivity in comparison operations.ĭescribes how to configure linked server definitions, which allow Transact-SQL statements run in an instance to work with data stored in separate OLE DB data sources.ĭescribes how to create a logon trigger, which specifies actions to be taken after a logon attempt has been validated, but before it starts working with resources in the instance. Configure defaults such as file locations and date formats, or how the instance uses operating system resources, such as memory or threads.Ĭonfigure Database Engine Instances (SQL Server)ĭescribes how to manage the collation for an instance of the Database Engine. Related Tasks Task Descriptionĭescribes how to configure the properties of an instance. There is no requirement to install a default instance all of the instances running on a computer can be named instances. A connection request must specify both the computer name and instance name in order to connect to the instance. A named instance is one where you specify an instance name when installing the instance. If a connection request specifies only the name of the computer, the connection is made to the default instance. One instance can be the default instance. ![]() You can run multiple instances of the Database Engine on a computer. Any data retrieved is returned to the application, along with any messages such as errors. The instance resolves the Transact-SQL statements into operations against the data and objects in the databases, and if the required permissions have been granted to the login credentials, performs the work. When a connection has been completed, an application sends Transact-SQL statements across the connection to the instance. If the application and instance are on the same computer, the SQL Server connection can run as either a network connection or an in-memory connection. The connection runs through a network connection if the application and instance are on separate computers. It is the target of the connection requests (logins) from applications. InstancesĪn instance of the Database Engine operates as a service that handles all application requests to work with the data in any of the databases managed by that instance. Applications connect to the instance in order to perform work in a database managed by the instance. Each computer can run multiple instances of the Database Engine. ![]() ![]() Each instance manages several system databases and one or more user databases. An instance of the Database Engine is a copy of the sqlservr.exe executable that runs as an operating system service.
