背景

同事在使用數(shù)據(jù)泵導(dǎo)入dmp文件時(shí)，拋出了一個(gè)異常

ORA-39171: Job is experiencing a resumable wait. ORA-01691: unable to extend lob segment CC_CK.SYS_LOB0000089385C00045$$ by 128 in tablespace USERS

USERS表空間無(wú)法擴(kuò)展了.

事實(shí)上，我們的數(shù)據(jù)不應(yīng)該存放在默認(rèn)的表空間內(nèi)。

---

概述

USERS表空間也就是默認(rèn)用戶表空間。
在創(chuàng)建一個(gè)用戶并沒(méi)有指定此用戶使用表空間時(shí)，該用戶所有信息都會(huì)放入到users表空間中。

常用操作

查看默認(rèn)用戶表空間

SQL>select * from database_properties where property_name like '%DEF%';

---

創(chuàng)建表空間

SQL> create tablespace TAB_XGJ datafile '/oradata/datafile/tab_xgj01.dbf' size 1024m autoextend on next 2000M maxsize unlimited extent management local autoallocate segment space management auto ;

各種屬性根據(jù)實(shí)際情況取舍。

---

指定單個(gè)用戶默認(rèn)表空間

建立用戶時(shí)直接指定

SQL> create user xgj identified by xgj default tablespace tab_xgj;

或者

SQL> create user xgj identified by xgj ; SQL> alter user xgj default tablespace tab_xgj;

如果需要指定臨時(shí)表空間

SQL>create user xgj identified by xgj default tablespace tab_xgjtemporary tablespace temp;

---

查看所有用戶的默認(rèn)表空間

SQL> select username,default_tablespace from dba_users;
