oracle创建表空间、创建用户、授权角色和导入导出用户数据

使用数据库管理员身份登录

-- log as sysdba
sqlplus / as sysdba;

创建临时表空间

-- create temporary tablespace
create temporary tablespace szdt_temp_data
tempfile 'd:\szdt-environment\oracle-datafiles\szdt_temp_data.dbf'
size 32m
autoextend on
next 32m maxsize unlimited
extent management local;

创建表空间

-- create tablespace
create tablespace szdt_data
logging
datafile 'd:\szdt-environment\oracle-datafiles\szdt_data.dbf'
size 32m
autoextend on
next 32m maxsize unlimited
extent management local;

创建用户

-- create user
create user szdt identified by szdt
account unlock
default tablespace szdt_data
temporary tablespace szdt_temp_data;

给用户授予权限

-- grant permission to user
grant dba,connect,resource to szdt;

删除用户

-- delete user
drop user szdt cascade;

删除临时表空间/表空间

-- delete tempory tablespace / tablespace
drop tablespace szdt_temp_data including contents and datafiles;
drop tablespace szdt_data including contents and datafiles;

连接到用户

-- connect to user
conn szdt/szdt@127.0.0.1:1521/orcl

导出dmp文件

-- export to dmp file
exp szdt/szdt@orcl file=d:/szdt-environment/backup-dmps/szdt.dmp

导入dmp文件

-- import from dmp file
imp szdt/szdt@orcl file=d:/szdt-environment/backup-dmps/szdt.dmp full=y

这些就是oracle在命令行下创建表空间、创建用户、授权角色和导入导出用户数据的所有操作命令。
