使用RMAN備份與恢復數據庫（8）——數據庫的備份與恢復
備份數據庫時會自動備份參數文件和控制文件。實際上，只要備份system表空間就會自動備份參數文件和控制文件。
一、使用RMAN備份數據庫
1、備份數據庫
命令以下：
RMAN> backup as compressed backupset database format '/home/oracle/rmanbak/database_%d_%I_%s_%p_%T';
Starting backup at 2020-04-10 08:06:27

2、查看備份集
可以看到，在備份數據庫的時候自動備份了參數文件和控制文件。結果如下：

二、使用RMAN恢復數據庫
1、修改數據
連接scott用戶，在t2表中添加數據：
SQL> select * from t2;
ID
----------
1
2
Elapsed: 00:00:00.10
SQL> insert into t2 values(11);
1 row created.
Elapsed: 00:00:00.03
SQL> commit;
Commit complete.
Elapsed: 00:00:00.00
SQL> select * from t2;
ID
----------
1
2
11
2、刪除參數文件、控制文件和所有的數據文件
（1）查看和刪除參數文件
SQL> show parameter spfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /usr/local/oracle/product/11.2.0/db_1/dbs/spfileorcl.ora
SQL> host rm /usr/local/oracle/product/11.2.0/db_1/dbs/spfileorcl.ora
（2）查看和刪除所有的數據文件
SQL> select name from v$datafile;
NAME
---------------------------------------------------------------------------------------
/usr/local/oradata/orcl/system01.dbf
/usr/local/oradata/orcl/sysaux01.dbf
/usr/local/oradata/orcl/undotbs01.dbf
/usr/local/oradata/orcl/users01.dbf
/usr/local/oradata/orcl/data01.dbf
Elapsed: 00:00:00.08
SQL>
SQL> host rm /usr/local/oradata/orcl/*.dbf
（3）查看和刪除所有的控制文件
SQL> select name from v$controlfile;
NAME
----------------------------------------------------------------------------------
/usr/local/oradata/orcl/control01.ctl
/usr/local/oracle/flash_recovery_area/orcl/control02.ctl
Elapsed: 00:00:00.01
SQL> host rm /usr/local/oradata/orcl/control01.ctl
SQL> host rm /usr/local/oracle/flash_recovery_area/orcl/control02.ctl
3、重啓數據庫
此時可以發現，已經無法啓動實例，應爲參數文件丟失導致數據庫實例無法啓動。
SQL> startup force;
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/usr/local/oracle/product/11.2.0/db_1/dbs/initorcl.ora'
4、在RMAN中執行startup nomount
RMAN> startup nomount;
startup failed: ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/usr/local/oracle/product/11.2.0/db_1/dbs/initorcl.ora'
starting Oracle instance without parameter file for retrieval of spfile
Oracle instance started

Fixed Size 2211448 bytes
Variable Size 92275080 bytes
Database Buffers 58720256 bytes
Redo Buffers 5455872 bytes
5、恢復參數文件
RMAN> restore spfile from '/home/oracle/rmanbak/database_ORCL_1559168802_93_1_20200410';
Starting restore at 2020-04-10 08:25:04
using channel ORA_DISK_1
channel ORA_DISK_1: restoring spfile from AUTOBACKUP /home/oracle/rmanbak/database_ORCL_1559168802_93_1_20200410
channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete
Finished restore at 2020-04-10 08:25:05
6、在RMAN中停庫
RMAN> shutdown immediate
Oracle instance shut down
7、連接sys用戶，啓動數據庫到nomount
SQL> startup nomount;
ORACLE instance started.
Total System Global Area 1068937216 bytes
Fixed Size 2220200 bytes
Variable Size 482348888 bytes
Database Buffers 578813952 bytes
Redo Buffers 5554176 bytes
8、利用RMAN恢復控制文件
RMAN> restore controlfile from '/home/oracle/rmanbak/database_ORCL_1559168802_92_1_20200410';
Starting restore at 2020-04-10 08:29:14
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=10 device type=DISK
channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
output file name=/usr/local/oradata/orcl/control01.ctl
output file name=/usr/local/oracle/flash_recovery_area/orcl/control02.ctl
Finished restore at 2020-04-10 08:29:15
9、啓動數據庫到mount
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
10、還原數據庫
在還原數據庫時出現以下錯誤，提示找不到系統表空間和data01表空間對應的文件：
RMAN> restore database;
Starting restore at 2020-04-10 08:30:31
Starting implicit crosscheck backup at 2020-04-10 08:30:31

發現可能是恢復參數文件和控制文件之後，RMAN目錄中的信息丟失造成的。通過list backup命令檢查發現，參數文件、控制文件、歸檔日誌文件的備份信息也丟失了。
重新在RMAN目錄中註冊備份信息：

然後，重新還原數據庫，發現可以正常執行restore命令：
RMAN> restore database;
