首先如果有用户存在需要删除用户的
drop user username cascade;
如果删除不了,可能情况当前用户处于连接状态,可以查找session
select username, sid, serial# from v$session WHERE USERNAME=username;
alter system kill session ‘sid,serial#’
3.如果想要保险起见就先把当前用户lock掉;
alter user username account lock;
4.如果当前需要删除的表空间(临时)还是别的用户的默认表空间
select * from v$session
select username,default_tablespace from dba_users where username=’用户名’;
如果还存在两种处理方式:1.修改所查询到的用户默认表空间和临时表空间
alter user naro default tablespace TABLESPACENAME;
alter user naro default temporary tablespace TEMPNAME;
5.至此即可删除表空间(临时)
drop tablespace TABLESPACENAME including contents and datafiles CASCADE CONSTRAINTS;
drop tablespace TEMPSPACENAME including contents and datafiles CASCADE CONSTRAINTS;
6.创建新的表空间(临时)
create tablespace SPACENAME datafile ‘E:\database\data’ size 200M autoextend on next 200m maxsize 20480m extent management local;
create temporary tablespace TEMPNAME tempfile ‘E:\database\temp’ size 200M autoextend on next 200m maxsize 20480m extent management local;
7.创建用户赋权和默认表空间
CREATE USER username IDENTIFIED BY NARO ACCOUNT UNLOCK
DEFAULT TABLESPACE SPACENAME TEMPORARY TABLESPACE TEMPNAME ;
8.赋权
GRANT CONNECT,RESOURCE TO username ;
GRANT DBA TO username ;
搞定!!!!!!
