Oracle ORA-01652 错误解决

ORA-01652: 无法通过 128 (在表空间 TEMP 中) 扩展 temp 段。一般情况下,在完成Select语句、create index等一些使用TEMP表空间的

  现象:ORA-01652: 无法通过 128 (在表空间 TEMP 中) 扩展 temp 段

  一般情况下,在完成Select语句、create index等一些使用TEMP表空间的排序操作后,Oracle是会自动释放掉临时段a的。但有些有侯我们则会遇到临时段没有被释放,TEMP表空间几乎满的状况,甚至是我们重启了数据库仍没有解决问题。下面我总结一下,给出几种处理方法。

  方法一、重启库

  库重启时,Smon进程会完成临时段释放,TEMP表空间的清理操作,不过很多的时侯我们的库是不允许down的,所以这种方法缺少了一点的应用机会,,不过这种方法还是很好用的。

  方法二、Metalink给出的一个方法

  修改一下TEMP表空间的storage参数,让Smon进程观注一下临时段,从而达到清理和TEMP表空间的目的。

  SQL>alter tablespace temp increase 1;

  SQL>alter tablespace temp increase 0;

  方法三、我常用的一个方法,具体内容如下:

  1、 使用如下语句a查看一下认谁在用临时段

  SELECT username,

  sid,

  serial#,

  sql_address,

  machine,

  program,

  tablespace,

  segtype,

  contents

  FROM v$session se,

  v$sort_usage su

  WHERE se.saddr=su.session_addr

  2、那些正在使用临时段的进程

  SQL>Alter system kill session 'sid,serial#';

  3、把TEMP表空间回缩一下

  SQL>Alter tablespace TEMP coalesce;

  方法四、使用诊断事件的一种方法,也是被我认为是“杀手锏”的一种方法

  1、 确定TEMP表空间的ts#

  SQL>select ts#, name from sys.ts$ ;

  TS# NAME

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

  0 SYSYEM

  1 RBS

  2 USERS

  3* TEMP

  4 TOOLS

  5 INDX

  6 DRSYS

  2、 执行清理操作

  SQL>alter session set events 'immediate trace

  name DROP_SEGMENTS level 4' ;

  说明:

  temp表空间的TS# 为 3*, So TS#+ 1= 4

  其它:

  1、 出现如上问题的原因我认为可能是由于大的排序超出了TEMP表空间的空间允许范围引起的。也可能包含着其它的异常的因素。

  2、 观注TEMP等这些空间的状态是Dba日常职责之一,我们可以通过Toad、Object Browser等这些工具办到,也可以用如下的语句:

  SELECT UPPER(F.TABLESPACE_NAME) "表空间名",

  D.TOT_GROOTTE_MB "表空间大小(M)",

  D.TOT_GROOTTE_MB - F.TOTAL_BYTES "已使用空间(M)",

  TO_CHAR(ROUND((D.TOT_GROOTTE_MB - F.TOTAL_BYTES) / D.TOT_GROOTTE_MB * 100,

  2),

  '990.99') "使用比",

  F.TOTAL_BYTES "空闲空间(M)",

  F.MAX_BYTES "最大块(M)"

  FROM (SELECT TABLESPACE_NAME,

  ROUND(SUM(BYTES) / (1024 * 1024), 2) TOTAL_BYTES,

  ROUND(MAX(BYTES) / (1024 * 1024), 2) MAX_BYTES

  FROM SYS.DBA_FREE_SPACE

  GROUP BY TABLESPACE_NAME) F,

  (SELECT DD.TABLESPACE_NAME,

  ROUND(SUM(DD.BYTES) / (1024 * 1024), 2) TOT_GROOTTE_MB

  FROM SYS.DBA_DATA_FILES DD

  GROUP BY DD.TABLESPACE_NAME) D

  WHERE D.TABLESPACE_NAME = F.TABLESPACE_NAME

  ORDER BY 4 DESC;
