ORA-25153: Temporary Tablespace is Empty

在一测试环境做测试的时候发生以下错误：

SQL> exec dbms_stats.gather_table_stats(ownname=>'SYS',tabname=>'TT',method_opt=>'for columns size 1 id',cascade=>true);
BEGIN dbms_stats.gather_table_stats(ownname=>'SYS',tabname=>'TT',method_opt=>'for columns size 1 id',cascade=>true); END;

查看临时表空间：temp表空间是处于online状态

SQL> select tablespace_name,status from dba_tablespaces;

但是没有发现临时文件：

SQL> select name from v$tempfile;    --发现临时文件丢失
no rows selected

查看物理文件：文理文件仍然存在

从物理文件的时间戳可以看出temp文件最后一次访问时间

根据时间查看alert日志，发现在对应的时间做个重建控制文件操作，并且在重建控制完成后启动数据库后在alert日志中发现以下内容：

*********************************************************************
WARNING: The following temporary tablespaces contain no files.
         This condition can occur when a backup controlfile has
         been restored.  It may be necessary to add files to these
         tablespaces.  That can be done using the SQL statement:

         ALTER TABLESPACE <tablespace_name> ADD TEMPFILE

         Alternatively, if these temporary tablespaces are no longer
         needed, then they can be dropped.
           Empty temporary tablespace: TEMP
*********************************************************************

说明是重建控制文件后，丢失了临时文件。（rman恢复数据库时也会发生类似现象）

只要把临时文件重新添加即可。

SQL> alter tablespace temp add tempfile '/u01/app/oracle/oradata/db11/temp01.dbf';

Tablespace altered.
