--//简单测试 List Failure, Advise Failure and Repair Failure命令在11g下,也许以后工作需要.
--//虽然我自己很少使用这个命令,感觉这个有点傻瓜化.
1.环境:
SYS@book> @ &r/ver1

2.建立测试环境:
--//建立备份:
delete archivelog all;
backup database format '/home/oracle/backup/full_%U';
backup archivelog all format '/home/oracle/backup/archive_%U';
--//过程略.
3.关闭数据库,删除一个数据文件:
RMAN> shutdown immediate ;
database closed
database dismounted
Oracle instance shut down
$ mv /mnt/ramdisk/book/tea01.dbf /mnt/ramdisk/book/tea01.dbf_20171031
4.启动数据库:
SYS@book> startup

Database mounted.

ORA-01110: data file 6: '/mnt/ramdisk/book/tea01.dbf'
SYS@book> select open_mode from v$database ;

5.通过以下命令观察:
--//List Failure;
RMAN> List Failure;
