Oracle:热备份和完全恢复实例模拟演示代码

热备份和完全恢复实例模拟演示代码

先创建表，输入数据，然后备份。之后删除表数据，完全恢复，得到有表里面有数据的状态？

SQL> conn / as sysdba

SQL> create tablespace test datafile ‘d:\test.dbf’ size 1M;

需要归档模式

ARCHIVE LOG LIST;

设置归档模式

SQL> SHUTDOWN;

SQL> STARTUP MOUNT;

SQL> ALTER DATABASE ARCHIVELOG;

SQL> ALTER DATABASE OPEN;

SQL> alter tablespace test begin backup

SQL> host copy d:\test.dbf c:\test.dbf

SQL> alter tablespace test end backup

SQL> create table test (a int ,b int ) tablespace test

SQL> insert into test values(1,1)

SQL> insert into test values(1,2)

SQL> commit

SQL> shutdown

SQL> host del d:\test.dbf

SQL> startup

SQL> alter database datafile 'd:\test.dbf' offline;

SQL> host copy c:\test.dbf d:\test.dbf

SQL> alter database recover datafile 'd:\test.dbf'

SQL> alter database datafile 'd:\test.dbf' online;

SQL> alter database open

SQL> select * from test
