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

BajaNivel 1Automatizadamssql

Descripción

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. Default: By default, the database property AUTO_CLOSE is OFF which is equivalent to is_auto_close_on = 0. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.
