At the end of the day,while all three production database instances are running,you execute the following command on the ASM instance:
SQL>shutdown immediate;
What is the result of executing this command?
A. The ASM instance is shut down,but the other instances are still running.
B. It results in an error because other database instances are connected to it.
C. All the instances,including the ASM instance,are shut down in the IMMEDIATE mode.
D. HRDB,FINDB,and ORGDB instances are shut down in the ABORT mode and the ASM instance is shut down in the IMMEDIATE mode.
答案：（B）
解析：
有连接的RDBMS实例时，不应用NORMAL、IMMEDIATE和TRANSACTIONAL形式的关闭，否则将返回下面的错误：
SQL>shutdown
ORA-15097:cannot SHUTDOWN ASM instance with connected client(process 14372)）
