ORA-01652:无法通过128(在表空间space中)扩展temp段

当“space=用户表空间 ”时报错处理:
 
--查看表空间的大小;
 
SQL> SELECT TABLESPACE_NAME,SUM(BYTES)/1024/1024 MB FROM DBA_FREE_SPACE GROUP BY TABLESPACE_NAME;
 
--查看表空间中数据文件存放的路径:
 
SQL> SELECT TABLESPACE_NAME, BYTES/1024/1024 FILE_SIZE_MB, FILE_NAME FROM DBA_DATA_FILES;
 
--错误处理:附加表空间
 
--alter tablespace TESTSPACE add datafile 'D:\MYSPACE01.DBF' size 20480m
 
当“space=temp ”时报错处理: 
 
临时表空间的作用:
 
  临时表空间主要用途是在数据库进行排序运算[如创建索引、order by及group by、distinct、union/intersect/minus/、sort-merge及join、analyze命令]、管理索引[如创建索引、IMP进行数据导入]、访问视图等操作时提供临时的运算空间,当运算完成之后系统会自动清理。
 
  当临时表空间不足时,表现为运算速度异常的慢,,并且临时表空间迅速增长到最大空间(扩展的极限),并且一般不会自动清理了。
 
  如果临时表空间没有设置为自动扩展,则临时表空间不够时事务执行将会报ora-01652无法扩展临时段的错误,当然解决方法也很简单:1、设置临时数据文件自动扩展,或者2、增大临时表空间。
 
  临时表空间的相关操作:
 
  查询默认临时表空间:
  
 SQL> select * from database_properties where property_name='DEFAULT_TEMP_TABLESPACE';
 
PROPERTY_NAME
 ------------------------------
 PROPERTY_VALUE
 --------------------------------------------------------------------------------
 DESCRIPTION
 --------------------------------------------------------------------------------
 DEFAULT_TEMP_TABLESPACE
 TEMP
 Name of default temporary tablespace
 
查询临时表空间状态:
 SQL> select tablespace_name,file_name,bytes/1024/1024 file_size,autoextensible from dba_temp_files;
 
TABLESPACE_NAME
 ------------------------------
 FILE_NAME
 --------------------------------------------------------------------------------
  FILE_SIZE AUT
 ---------- ---
 TEMP
 /opt/Oracle/oradata/TEST/temp01.dbf
        65 YES
 
查询临时表空间动态视图:
 SQL> select * from v$tempfile;
 
    FILE# CREATION_CHANGE# CREATION_TIM        TS#    RFILE# STATUS
 ---------- ---------------- ------------ ---------- ---------- -------
 ENABLED        BYTES    BLOCKS CREATE_BYTES BLOCK_SIZE
 ---------- ---------- ---------- ------------ ----------
 NAME
 --------------------------------------------------------------------------------
          1          446436 09-DEC-08            3          1 ONLINE
 READ WRITE  68157440      8320    20971520      8192
 /opt/oracle/oradata/TEST/temp01.dbf
 
扩展临时表空间:
 
  方法一、增大临时文件大小:
 
  SQL> alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf'  resize 100m;
 
  Database altered.
 
  方法二、将临时数据文件设为自动扩展:
 
  SQL>  alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' autoextend on next 5m maxsize unlimited;
 
扩展表空间时报错:
 SQL> alter database tempfile  '/opt/oracle/oradata/TEST/temp01.dbf' resize 100m;
 alter database tempfile  '/opt/oracle/oradata/TEST/temp01.dbf' resize 100m
 *
 ERROR at line 1:
 ORA-00376: file 201 cannot be read at this time
 ORA-01110: data file 201: '/opt/oracle/oradata/TEST/temp01.dbf'
 

SQL>  alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' autoextend on next 5m maxsize unlimited;
  alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' autoextend on next 5m maxsize unlimited
 *
 ERROR at line 1:
 ORA-00376: file 201 cannot be read at this time
 ORA-01110: data file 201: '/opt/oracle/oradata/TEST/temp01.dbf'
 

原因是临时表空间不知道什么原因offline了,修改为online后修改成功。
 SQL>  alter database tempfile '/opt/oracle/oradata/TEST/temp01.dbf' online;
 Database altered.
