ORA-01100 数据文件丢失,无备份,有创建数据文件以后的所有归档的恢复

本次实验是测试在数据文件丢失,无备份,有归档日志的情况下的恢复,是看到itpub一个人的提问,这种情况在生产环境中基本不存在,因为不可能会保留那么的归档日志。整个实验的前提条件是:数据库运行在归档模式,并且从创建数据文件文件以来的归档日志必须存在。

Tablespace created.

 

www.htz.pw > drop table scott.htz;

 

Table dropped.

 

www.htz.pw > create table scott.htz as select * from dba_objects where rownum=1;

 

Table created.

 

www.htz.pw > select count(*) from scott.htz;

 

  COUNT(*)

4,删除数据文件与在线日志

[oracle@www.htz.pw orcl1124]$rm htz0101.dbf

[oracle@www.htz.pw orcl1124]$rm htz0101.dbf

5,启动数据库报ORA-01110错误
