Oracle数据库创建表空间及用户授权

/*分为四步 */
/*第1步:创建临时表空间 */

create temporary tablespace test_temp
tempfile 'E:\app\Administrator\oradata\emis\datafile\test_temp.dbf'
size 50m
autoextend on
next 50m maxsize 2048m
extent management local;

  

/* linux服务器上操作 */

create temporary tablespace test_temp tempfile '/u01/app/oracle/oradata/EMIS/datafile/test_temp.dbf' size 50m autoextend on next 50m maxsize 2048m extent management local;

  

/*第2步:创建数据表空间 */

create tablespace test_data
logging
datafile 'E:\app\Administrator\oradata\emis\datafile\test_data.dbf'
size 50m
autoextend on
next 50m maxsize 2048m
extent management local;

  

/* linux服务器上操作 */

create tablespace test logging datafile '/u01/app/oracle/oradata/EMIS/datafile/test_data.dbf' size 50m autoextend on next 50m maxsize 2048m extent management local;

  

/*第3步:创建用户并指定表空间 */
CREATE USER 用户名
IDENTIFIED BY 密码
DEFAULT TABLESPACE 表空间(默认USERS)
TEMPORARY TABLESPACE 临时表空间(默认TEMP)

create user C##test identified by 123456
default tablespace test_data
temporary tablespace test_temp;

  

/* linux服务器上操作 */

create user test identified by 123456 default tablespace test temporary tablespace test_temp;

  

如果建的是CDB容器数据库,则用户必须加C##,可以用dbca重新建一个库,然后不要选择CDB 就会和以前的版本一样没有这个限制,CDB不适合新手或者初学者

/*第4步:给用户授予权限 */

grant connect,resource,dba,create session,create table,create view to C##test;

  

/* 移除授权 */

revoke connect from test

  

/* 删除表空间 */

DROP TABLESPACE tablespace_name INCLUDING CONTENTS AND DATAFILES;

  

/* 解锁用户 */

ALTER USER username ACCOUNT UNLOCK;

  

/* 修改用户密码 */

ALTER USER EMIS_FRAME IDENTIFIED BY EMIS_FRAME;
ALTER USER system identified by xxzx#emis#73;

  

查看已经创建好的表空间:

select default_tablespace, temporary_tablespace, d.username from dba_users d;

  

/* Linux上正式创建表空间和用户 */

create temporary tablespace EMIS_TEST_TEMP tempfile '/u01/app/oracle/oradata/EMIS/datafile/EMIS_TEST_TEMP.dbf' size 50m autoextend on next 50m maxsize 2048m extent management local;

create tablespace EMIS_TEST logging datafile '/u01/app/oracle/oradata/EMIS/datafile/EMIS_TEST_DATA.dbf' size 50m autoextend on next 50m maxsize 2048m extent management local;

create user EMIS_TEST identified by EMIS_TEST default tablespace EMIS_TEST temporary tablespace EMIS_TEST_TEMP;

grant connect,resource,dba,create session,create table,create view to EMIS_TEST;
