Oracle数据库常用操作

--1：创建临时表空间
create temporary tablespace givaName_temp tempfile 'F:\orcal\orcalan\hsj\givaName_temp.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;

--2：创建数据表空间
create tablespace givaName logging datafile 'F:\orcal\orcalan\hsj\givaName.dbf' size 50m autoextend on next 50m maxsize unlimited extent management local;

--第3步：创建用户并指定表空间
create user givaName identified by 密码 default tablespace givaName temporary tablespace givaName_temp;

--第4步：给用户授予权限
grant connect,resource,dba to givaName ;
grant create  database link to givaName
--查询数据库中的表空间名称及大小
select t.tablespace_name, round(sum(bytes/(1024*1024)),0) ts_size
from dba_tablespaces t, dba_data_files d
where t.tablespace_name = d.tablespace_name
group by t.tablespace_name;

cmd命令

SELECT s.username,l.OBJECT_ID,l.SESSION_ID,s.SERIAL#,
l.ORACLE_USERNAME,l.OS_USER_NAME,l.PROCESS
FROM V$LOCKED_OBJECT l,V$SESSION S WHERE l.SESSION_ID=S.SID;

--alter system kill session 'SESSION_ID,SERIAL#'
