3、 继续在测试表中插入记录 SQL> insert into test values(2); 1 row inserted SQL> commit; Commit complete
SQL> select * from test; A
--------------------------------------- 1 2 SQL>alter system switch logfile; System altered.
SQL> alter system switch logfile; System altered.
4、 关闭数据库，模拟丢失数据文件 SQL> shutdown immediate; Database closed. Database dismounted. Oracle instance shut down
C:\\>del D:\\Oracle\\ORADATA\\TEST\\SYSTEM01.DBF C:\\>del D:\\Oracle\\ORADATA\\TEST\\INDX01.DBF C:\\>del D:\\Oracle\\ORADATA\\TEST\\TOOLS01.DBF C:\\>del D:\\Oracle\\ORADATA\\TEST\\RBS01.DBF
5、启动数据库，检查错误 SQL> STARTUP
Oracle instance started.

ORA-01157: cannot identify/lock data file 1 - see DBWR trace file ORA-01110: data file 1: 'D:\\Oracle\\ORADATA\\TEST\\SYSTEM01.DBF'
查询v$recover_file
SQL> select * from v$recover_file;
FILE# ONLINE ERROR CHANGE# TIME ---------- ------- ------------------ ---------- ----------- 1 ONLINE FILE NOT FOUND 0 2 ONLINE FILE NOT FOUND 0 5 ONLINE FILE NOT FOUND 0 6 ONLINE FILE NOT FOUND 0 可以知道有四个数据文件需要恢复.
6、利用RMAN进行恢复 C:\\>rman
Recovery Manager: Release 8.1.6.0.0 - Production RMAN> connect rcvcat rman/rman@back
RMAN-06008: connected to recovery catalog database RMAN> connect target internal/virpure
RMAN-06005: connected to target database: TEST (DBID=1788174720) RMAN> run{
2> allocate channel c1 type disk; 3> restore database; 4> recover database;
5> sql 'alter database open'; 6> release channel c1; 7> }
