[20171031]rman xxx Failure.txt

--//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

PORT_STRING                    VERSION        BANNER

------------------------------ -------------- --------------------------------------------------------------------------------

x86_64/Linux 2.4.xx            11.2.0.4.0     Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

RMAN> report schema;

List of Permanent Datafiles

===========================

2    940      SYSAUX               ***     /mnt/ramdisk/book/sysaux01.dbf

List of Temporary Files

=======================

---- -------- -------------------- ----------- --------------------

1    414      TEMP                 32767       /mnt/ramdisk/book/temp01.dbf

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

ORACLE instance started.

Total System Global Area  634732544 bytes

Variable Size             197133392 bytes

Redo Buffers                7524352 bytes

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;

Automated Repair Options

Option Repair Description

------ ------------------

1      Restore and recover datafile 6

  Strategy: The repair includes complete media recovery with no data loss

  Repair script: /u01/app/oracle/diag/rdbms/book/book/hm/reco_4210181035.hm

$ cat /u01/app/oracle/diag/rdbms/book/book/hm/reco_4210181035.hm

   # restore and recover datafile

   restore datafile 6;

   recover datafile 6;

   sql 'alter database datafile 6 online';

--//可以发现修复脚本.再次执行Advise Failure ;还是在目录/u01/app/oracle/diag/rdbms/book/book/hm/生产不同的文件.

--//Repair Failure

RMAN> Repair Failure preview;
