数据库管理

1.查看我们常规将用户表空间放置位置

select name from v$datafile;

2.创建表空间

##CREATE TABLESPACE 表空间名 LOGGING DATAFILE '表空间地址' SIZE 200M AUTOEXTEND ON NEXT 32M MAXSIZE 500M EXTENT MANAGEMENT LOCAL;

SQL> CREATE TABLESPACE PCSPC LOGGING DATAFILE '/u01/app/oracle/oradata/ORCL/users02.dbf' SIZE 200M AUTOEXTEND ON NEXT 32M MAXSIZE 500M EXTENT MANAGEMENT LOCAL;

3.创建用户，指定上面的密码和表空间。

##CREATE USER 用户名 IDENTIFIED BY 用户密码 DEFAULT TABLESPACE 表空间名;

SQL> CREATE USER admin IDENTIFIED BY oracle DEFAULT TABLESPACE PCSPC;

4.赋予admin用户权限。

##grant connect,resource to 用户名;

##grant unlimited tablespace to 用户名;

##grant create database link to 用户名;

##grant select any sequence,create materialized view to 用户名;

SQL> grant connect,resource to admin;

SQL> grant unlimited tablespace to admin;

SQL> grant create database link to admin;

SQL> grant select any sequence,create materialized view to admin;
