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;

MySQL: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

MySQL's Role: Databases in Web Applications MySQL's Role: Databases in Web Applications Apr 17, 2025 am 12:23 AM

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
