RMAN备份方案(二)
ed.
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. Total System Global Area 102020364 bytes Fixed Size 70924 bytes Variable Size 85487616 bytes Database Buffers 16384000 bytes Redo Buffers 77824 bytes Database mounted. 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> }
