使用_allow_resetlogs_corruption打开无归档日志rman备份库,运维DBA反映服务器宕机后,开启数据库报错ORA-01194 ORA-01110,分析原因为Oracle SCN不一致导致数据库无法启动,使用_allow_resetlogs_corruption打开数据库

1.rman还原恢复操作

--还原数据库
RMAN> restore database;
--恢复数据库
RMAN> recover database;
Starting recover at 2012-03-08 21:20:45
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=65 device type=DISK
starting media recovery
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of recover command at 03/08/2012 21:20:47
RMAN-06053: unable to perform media recovery because of missing log
RMAN-06025: no backup of archived log for thread 1 with sequence 2936 and starting SCN of 25991695 found to restore
RMAN-06025: no backup of archived log for thread 1 with sequence 2935 and starting SCN of 25991652 found to restore
RMAN-06025: no backup of archived log for thread 1 with sequence 2934 and starting SCN of 25991649 found to restore
……………………
RMAN-06025: no backup of archived log for thread 1 with sequence 2902 and starting SCN of 25991156 found to restore
这里报日志缺少,实际上是备份的数据库文件后,没有备份归档日志,归档日志全部丢失

进行不完全恢复

SQL> recover database until cancel; ORA-00279: change 25991194 generated at 03/08/2012 20:33:58 needed for thread 1 ORA-00289: suggestion : /opt/oracle/oradata/archivelog/chf/1_2902_752334071.dbf ORA-00280: change 25991194 for thread 1 is in sequence #2902 Specify log: {

=suggested | filename | AUTO | CANCEL} cancel ORA-01547: warning: RECOVER succeeded but OPEN RESETLOGS would get error below ORA-01194: file 1 needs more recovery to be consistent ORA-01110: data file 1: '/opt/oracle/oradata/chf/system01.dbf' ORA-01112: media recovery not started SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01194: file 1 needs more recovery to be consistent ORA-01110: data file 1: '/opt/oracle/oradata/chf/system01.dbf'

2.查看相关SCN

--此时所有scn均一致

3.尝试打开数据库

SQL> alter database open resetlogs; alter database open resetlogs * ERROR at line 1: ORA-01194: file 1 needs more recovery to be consistent ORA-01110: data file 1: '/opt/oracle/oradata/chf/system01.dbf' SQL> recover database using backup controlfile until cancel; ORA-00279: change 25991194 generated at 03/08/2012 20:33:58 needed for thread 1 ORA-00289: suggestion : /opt/oracle/oradata/archivelog/chf/1_2902_752334071.dbf ORA-00280: change 25991194 for thread 1 is in sequence #2902 Specify log: {

5.使用隐含参数打开数据库

SQL> create pfile='/tmp/pfile' from spfile;
File created.
-------/tmp/pfile中加上----------
_allow_resetlogs_corruption= TRUE
---------------------------------
SQL> startup mount pfile='/tmp/pfile' force
ORACLE instance started.
