This rule checks whether the AUTO_ CLOSE option is set OFF. When AUTO_CLOSE is set ON, this option can cause performance degradation on frequently accessed databases because of the increased overhead of opening and closing the database after each connection. AUTO_CLOSE also flushes the procedure cache after each connection.

Best Practices Recommendations
