Ensure 'AUTO_CLOSE' is set to 'OFF' on contained databases

낮음레벨 1자동mssql

설명

AUTO_CLOSE determines if a given database is closed or not after a connection terminates. If enabled, subsequent connections to the given database will require the database to be reopened and relevant procedure caches to be rebuilt. Because authentication of users for contained databases occurs within the database not at the server\instance level, the database must be opened every time to authenticate a user. The frequent opening/closing of the database consumes additional server resources and may contribute to a denial of service.
