Oracle Rman 恢复后重建临时表空间

问题：

Oracle经过Rman恢复后未重建临时表空间导致查询dba_temp_files报错：

SQL>select tablespace_name,file_name from dba_temp_files;

select tablespace_name,file_name from dba_temp_files

*

ERROR at line 1:

ORA-01187: cannot read from file 201 because it failed verification tests

ORA-01110: data file 201: '/oradata/datafiles/nmsa/temp01.dbf'

解决方法：

查看v$tempfile确定有几个temp临时表空间和对应的临时数据文件：

SQL>select file#,ts#,name,status from v$tempfile;

FILE# TS# NAME STATUS

---------------------- ------------------------ ------------------------------------------------- ------------------------

1 3 /oradata/datafiles/nmsa/temp01.dbf ONLINE

临时表空间reuse：

SQL>alter database tempfile '/oradata/datafiles/nmsa/temp01.dbf' drop;

Database altered.

SQL>alter tablespace temp add tempfile '/oradata/datafiles/nmsa/temp01.dbf' reuse;

Tablespace altered.

SQL>select tablespace_name,file_name from dba_temp_files;

TABLESPACE_NAME FILE_NAME

--------------------------------- ----------------------------------------------------------------

TEMP /oradata/datafiles/nmsa/temp01.dbf
