背景

同事在使用数据泵导入dmp文件时，抛出了一个异常

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表空间无法扩展了.

事实上，我们的数据不应该存放在默认的表空间内。

概述

USERS表空间也就是默认用户表空间。
在创建一个用户并没有指定此用户使用表空间时，该用户所有信息都会放入到users表空间中。

常用操作

查看默认用户表空间

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

 

  
1
 

创建表空间

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 ;

各种属性根据实际情况取舍。

指定单个用户默认表空间

建立用户时直接指定

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

 

  
1
 

或者

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

  

 

  
1
  
2
  
3
 

如果需要指定临时表空间

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

 

  
1
  
2
  
3
 

查看所有用户的默认表空间

SQL> select username,default_tablespace from dba_users;
  

 

  
1
 

创建用户实例

oracle@entel2:[/oracle]$sqlplus sys/system as sysdba;
