### Detailed Problem Statement ###
we preform a successful backup as the log we attached.we change the storage and tried to restore the backup,seq 35333 is the first archive log when we perform backup,and 35334 is the last archivelog.and after the backup successful,I runed "alter system archivelog current" from plsql and shutdown the datbase,so it comes an archive log 35335.we successful run " restore database" with no error,then it occres the errors below when run "recover database"

archive log thread 1 sequence 35334 is already on disk as file /u01/oracle/oradata/dbc/data4/arch/1_35334.arc

.....many more old logs required尝试restore归档回来

restore archivelog from logseq 35279 until logseq 35332;
it says mismatch logslist backup find the archivelogs backup below avaible:

resoter archivelog all and failed.
use the comand and succefull restore the archivelog

recover database using backup controlfile ;
it required 35334,type auto
it required 35335,copy my manul back archivelog 35335 to the directory and type auto
it required 35556, type cancel;

reported:
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/oracle/oradata/dbc/data1/system01.dbf'
we thought something wrong with the controlfile so we backup controlfile to trace and created the new controlfile,

open reset logs ,and the same error occured again.
ORA-01152: file 1 was not restored from a sufficiently old backup
ORA-01110: data file 1: '/u01/oracle/oradata/dbc/data1/system01.dbf'
we tried on a new mechine and try to restore also occure the error.
at last ,we use

_allow_terminal_recovery_corruption _allow_resetlogs_corruption on the pfile and succefully open the database.

事后跟踪原因：

1、看看所有文件的check_time

SQL> select file#,substr(name,1,50), substr(recover,1,1) R, substr(fuzzy,1,1) F,
2 to_char(checkpoint_time,'dd/mm/yyyy:hh24:mi:ss') ckpt_time,
3 checkpoint_change#, resetlogs_change#,
4 to_char(resetlogs_time,'dd/mm/yyyy HH24:MI:SS') tm from v$datafile_header;

71 /u01/oracle/oradata/dbc/data1/test__1.dbf N 30/03/2009:21:28:44 6102273276922 21739661701
01/12/2005 11:35:45

72 /u01/oracle/oradata/dbc/data1/tbs_03.dbf Y 09/08/2006:16:26:47 42315919273 21739661701
01/12/2005 11:35:45

73 /u01/oracle/oradata/dbc/data1/tbs__2.dbf N 30/03/2009:21:28:44 6102273276922 21739661701
01/12/2005 11:35:45

76 /u01/oracle/oradata/dbc/data2/tbs__12.dbf N 30/03/2009:21:28:44 6102273276922 21739661701

2、看看status

select file#,substr(name, 1, 50), status,enabled,to_char(creation_time,'dd/mm/yyyy:hh24:mi:ss') from v$datafile;

/u01/oracle/oradata/dbc/data2/tbs__11.dbf ONLINE READ WRITE 11/05/2006:09:45:51
71 /u01/oracle/oradata/dbc/data1/test_1.dbf ONLINE READ WRITE 22/07/2006:11:02:56
72 /u01/oracle/oradata/dbc/data1/tbs_03.dbf RECOVER READ WRITE 09/08/2006:16:26:46
73 /u01/oracle/oradata/dbc/data1/tbs__2.dbf ONLINE READ WRITE 11/09/2006:17:50:43
76 /u01/oracle/oradata/dbc/data2/tbs__12.dbf ONLINE READ WRITE 08/12/2006:09:36:08

and because of this datafile, you are getting the error.
+ You need to choose from any of the following options :

1. You need to recover this datafile till current time and bring it online and then database can be opened successfully
2. Take this datafile offline drop, open up the database and then drop the tablespace which contains this datafile. You can choose to export the data from other datafiles of the tablespace.

SQL> alter database datafile 72 offline drop;

Database altered.

SQL> alter database open resetlogs;
alter database open resetlogs

ORA-01113: file 1 needs media recovery
ORA-01110: data file 1: '/u01/oracle/oradata/dbc/data1/system01.dbf'


SQL> recover database using backup controlfile until cancel;

如果只是用recover database using backup controlfile，还是会出现同样的错打不开的。

这里是因为我用10.2.0.4的数据库去打开9.2.0.6的DB。

如何知道数据库是否可以打开？

+ Following queries can be used to determine if the database can be opened or not. The output of the queries should be as mentioned :

select distinct status from v$datafile; --> should return 2 row and value will be SYSTEM and ONLINE
select distinct (to_char(checkpoint_change#)) from v$datafile; --> should return 1 row
select distinct (to_char(checkpoint_change#)) from v$datafile_header; --> should return 1 row and same value as above
select distinct (status) from v$backup; --> should return 1 row and value should be "NOT ACTIVE"
select distinct (fuzzy) from v$datafile_header; --> should return 1 row and value should be "NO"

+ If all the output of above 5 queries is as mentioned, then the database can be opened else the database opening can fail with errors.

+ If the database has been opened, the file header, based on which recovery is done and Oracle asks for archives for further recovery, would have changed and so looking at the current file header, it is not possible to say why recovery required those archives.
