检查alert日志：
Errors in file /u01/pp/oracle/admin/ezhou/bdump/ezhou_dbw0_6672.trc:

File 201 not verified due to error ORA-01122
报我的test01.dbf 有问题。
我看一下：
SQL> select * from v$tempfile;
FILE# CREATION_CHANGE# CREATION_TIME TS# RFILE# STATUS

/u02/ezhou/temp01.dbf
是online 的。
思路：先offline 再online:
发现： offline 容易，online 难：
SQL> alter database tempfile '/u02/ezhou/temp01.dbf' offline;
Database altered.
SQL> alter database tempfile '/u02/ezhou/temp01.dbf' online;
alter database tempfile '/u02/ezhou/temp01.dbf' online
*
ERROR at line 1:
ORA-01122: database file 201 failed verification check
ORA-01110: data file 201: '/u02/ezhou/temp01.dbf'
ORA-01203: wrong incarnation of this file - wrong creation SCN
好，下面试试删除重建：
SQL> alter database tempfile '/u02/ezhou/temp01.dbf' drop;
Database altered.
SQL> alter tablespace temp add tempfile '/u02/ezhou/temp01.dbf' size 100m;
alter tablespace temp add tempfile '/u02/ezhou/temp01.dbf' size 100m
*
ERROR at line 1:
ORA-01109: database not open
没有办法。
在看一下log:
ORA-01122: database file 201 failed verification check
还是做一下datafile 的check 吧：
SQL> alter system check datafiles;
System altered.
SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery
SQL> alter database open;
Database altered.
SQL> select * from v$tempfile;
no rows selected
把原来的存在的文件：temp01.dbf 删除，重建：
SQL> alter tablespace temp add tempfile '/u02/ezhou/temp01.dbf' size 100m;
Tablespace altered.
好，现在database open， temp文件也有了。
