Oracle 10G 报错 ORA-00604 ORA-00376 ORA-01110
如果在做数据库迁移，由于你删除undotbs01.dbf 导致报如下错误：ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2: '/u01/app/oracle/oradata/orcl/undotbs01.dbf'
解决方案如下：
1.删除表空间文件与创建表空间文件
SQL> alter database datafile '/u01/app/oracle/oradata/orcl/undotbs01.dbf' offline drop;
Database altered.
SQL> alter database open
2 ;
Database altered.
SQL> create undo tablespace undotbs02 datafile '/u01/app/oracle/oradata/orcl/undotbs02.dbf' size 10M;
Tablespace created.
SQL> alter system set undo_tablespace='undotbs02';
System altered
2.查询介质恢复文件状态SQL> select * from v$recover_file;

红色表示已经被删除的表空间，现在处理不在线状态，这情况属于undo表空间不正常
蓝色表示已经创建了的表空间，没法使用
3.先介质恢复datafile 7 （7 OFFLINE）（最好是在mount状态下恢复，在此是open）
SQL> recover datafile 7;
Media recovery complete.
4.查询介质恢复文件状态
SQL> select * from v$recover_file;

5.执行删除datafile 2(2 OFFLINE)
SQL> alter database datafile 2 offline drop;
Database altered.
发现数据库还是不正常，此时查询表空间，看看是否在线
6.查询表空间状态
SQL> select tablespace_name,status from dba_tablespaces;
TABLESPACE_NAME STATUS
------------------------------------------------------------ ------------------

UNDOTBS1 ONLINE
SYSAUX ONLINE

UNDOTBS02 ONLINE
ETENTEST ONLINE
ETENTEST_TEMP ONLINE
11 rows selected.
发现表空间UNDOTBS1还在线，此时要drop
7.在open状态下drop表空间UNDOTBS1
SQL> drop tablespace undotbs1
2 ;
Tablespace dropped.
8.查询表空间状态
SQL> select tablespace_name,status from dba_tablespaces;

已经没有表空间UNDOTBS1
9.查询介质恢复文件状态
SQL> select * from v$recover_file;
no rows selected
一切正常，
10.关闭数据库与启动数据库
SQL> shutdown immediate;
