一、关闭数据库修改
1、使用mv方式(适用于文件系统)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 | sys@ORCL>shutdown immediate; shutdown immediate; Database closed.

2、RMAN备份方式(适用于文件系统、祼设备、ASM)
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 | sys@ORCL>shutdown immediate Database closed.
