Oracle RMAN 备份及不完全恢复(删除archievelog)
RMAN备份命令
|
backup Database format='/home/oracle/backup/bak_full_%U_%T' tag='bak_full'; |
备份完后插入测试数据
insert into zz values(2); commit;
insert into qq values(2); commit;
然后通过alter system switch logfile多切几次归档,切出多个归档文件
o1_mf_1_12_cpb2xhg8_.arc o1_mf_1_14_cpb36dbo_.arc
o1_mf_1_13_cpb35zgs_.arc o1_mf_1_15_cpb37ff2_.arc
删除12和14文件
[oracle@ocp 2016_06_18]$ rm o1_mf_1_12_cpb2xhg8_.arc
[oracle@ocp 2016_06_18]$ rm o1_mf_1_14_cpb36dbo_.arc
通过在RMAN中运行处理使得报错
run {
sql'alter database datafile 6 offline';
restore datafile 6;
recover datafile 6;
sql'alter database datafile 6 online';
}
错误为
|
RMAN> recover datafile 6; Starting recover at 18-JUN-16 starting media recovery archived log for thread 1 with sequence 13 is already on disk as file /u01/app/oracle/flash_recovery_area/ORCL/archivelog/2016_06_18/o1_mf_1_13_cpb35zgs_.arc |
查看archieve目录,发现确实只有
o1_mf_1_13_cpb35zgs_.arc o1_mf_1_15_cpb37ff2_.arc
查看v$log,得到最后需要应用的日志文件应该是16
SQL> select group#,sequence#,status from v$log;
GROUP# SEQUENCE# STATUS
---------- ---------- ----------------
1 16 CURRENT
2 14 INACTIVE
3 15 INACTIVE
被还原的6号文件的scn为
SQL> select file#,change# from v$recover_file;
FILE# CHANGE#
---------- ----------
6 1080514
查看v$log_history得知需要从10号文件开始恢复
SQL> select sequence# from v$log_history where 1080514 between first_change# and next_change#-1;
SEQUENCE#
----------
10

用scott/tiger登录后查看,发现插入的数据不在了.
打开后,需要重新备份数据库,备份前需要删除原有多余的backup set及archivelog
