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

FaibleNiveau 1Automatiséemssql

Description

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.

Méthode de vérification

sql_query

Sortie attendue: 0

Méthode de correction

Méthode de correction: Recommandation ou correctif d'infrastructure
