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%';
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;
或者
SQL> create user xgj identified by xgj ; SQL> alter user xgj default tablespace tab_xgj;
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;
查看所有用户的默认表空间
SQL> select username,default_tablespace from dba_users;
创建用户实例
