oracle丢失temp表空间处理

之前有做临时表空间的切换，切换后没drop tablespace就删除了temp01.dbf结果排序跟查dba_temp_files报错

SQL> select tablespace_name,file_id,file_name,bytes/1024/1024 Mbytes from dba_temp_files;

select tablespace_name,file_id,file_name,bytes/1024/1024 Mbytes from dba_temp_files

                                                                     *

ERROR at line 1:

ORA-01116: error in opening database file 201

ORA-01110: data file 201: '/home/oracle/oradata/osa/temp01.dbf'

ORA-27041: unable to open file

Linux-x86_64 Error: 2: No such file or directory

两种方法可以恢复

1、重启数据库

重启后系统会自动重建，数据库会提示re-creating在bdump的alter_sid.log中

Re-creating tempfile /home/oracle/oradata/osa/temp01.db

2、重建

alter tablespace temp add tempfile '/oracle/oradata/osa/temp03.dbf' size 50m;

alter tablespace temp drop  tempfile '/oracle/oradata/osa/temp01.dbf' ;
