ORA-01187: cannot read from file because it failed verification tests ORA-01110: data file
今天发现oracle的dataguard备库临时表空间temp无法查询dba_temp_files的视图:SQL> select tablespace_name, file_id, file_name,status,autoextensible, round(bytes/(1024*1024),0) total_spacefrom dba_temp_files order by tables

今天发现oracle的dataguard备库临时表空间temp无法查询dba_temp_files的视图:
SQL> select tablespace_name, file_id, file_name,status,autoextensible, round(bytes/(1024*1024),0) total_space from dba_temp_files order by tablespace_name,file_name;
select tablespace_name, file_id, file_name,status,autoextensible, round(bytes/(1024*1024),0) total_space from dba_temp_files order by tablespace_name,file_name

ERROR at line 1:
ORA-01187: cannot read from file because it failed verification tests
ORA-01110: data file 8194: '+CCSYS/cc/temp_001.dbf'
进一步检查:
SQL> col name format a60
SQL> set linesize 160
SQL> select s.name tbsname,t.name,(t.bytes/1024/1024) bytes,status
2 from v$tablespace s,v$tempfile t
3 where s.ts# = t.ts#;
TBSNAME NAME BYTES STATUS
------------------------------ ------------------------------------------------------------ ---------- -------
TEMP +CCDATA/DR_CC/TEMPFILE/temp.300.1052334269 20 ONLINE
TEMP +CCSYS/cc/temp_001.dbf 30720 ONLINE
发现表空的这个数据文件是online的,而且检查物理文件,发现也是存在的:
ASMCMD> ls -l +CCSYS/cc/temp_001.dbf
Type Redund Striped Time Sys Name
TEMPFILE MIRROR COARSE OCT 23 10:00:00 N temp_001.dbf => +CCSYS/CC/TEMPFILE/TEMP.260.1048969595
由于该库是dg的备库,是通过主库热备恢复的,但是临时表空间文件是不需要restore的,所以原表空间该数据文件跟恢复后的控制文件中记录的不一致,数据库并没有识别该数据文件,所以只需要先删除该临时数据文件人,然后重新添加一个一样数据文件名的数据文件即可:
SQL> alter database tempfile '+CCSYS/cc/temp_001.dbf' drop including datafiles;
Database altered.
此时再查询dba_temp_files视图就可以查询了:
SQL> select tablespace_name, file_id, file_name,status,autoextensible, round(bytes/(1024*1024),0) total_space from dba_temp_files order by tablespace_name,file_name;
TABLESPACE_NAME FILE_ID FILE_NAME STATUS AUT TOTAL_SPACE
-------------------- ---------- ---------------------------------------- ------- --- -----------
TEMP 1 +CCDATA/DR_CC/TEMPFILE/temp.300.10523342 ONLINE NO 20
69
再增加同名的数据文件到temp表空间,保持跟之前一致:
SQL> alter tablespace temp add tempfile '+CCSYS/cc/temp_001.dbf' SIZE 30g REUSE AUTOEXTEND off;
Tablespace altered.
SQL> select tablespace_name, file_id, file_name,status,autoextensible, round(bytes/(1024*1024),0) total_space from dba_temp_files order by tablespace_name,file_name;
TABLESPACE_NAME FILE_ID FILE_NAME STATUS AUT TOTAL_SPACE
-------------------- ---------- ---------------------------------------- ------- --- -----------
TEMP 1 +CCDATA/DR_CC/TEMPFILE/temp.300.10523342 ONLINE NO 20
69
TEMP 2 +CCSYS/cc/temp_001.dbf ONLINE NO 30720
