Steps to create tablespaces and users:

user

create user ID identified by "password";

grant create session to username;

grant create table to username;

grant create tablespace to username;

grant create view to username;

grant resource to

grant connect,resource,dba to user;

select * from user_sys_privs; Query current user permissions

grant connect,resource,dba to user; grant dba permissions

grant connect,resource to user;

grant unlimited tablespace to users;

grant create database link to user;

grant select any sequence,create materialized view to user;

grant unlimited tablespaces to users;//grant unlimited tablespaces

grant select any table to user;//grant query any table

grant is keyword, select any table is permission,to is followed by user account

[sql] view plain copy

tablespace

Create table spaces (generally N table spaces for storing data and an index space):

create tablespace name

datafile 'path (path to be built first)\***.dbf ' size *M

tempfile 'path\***.dbf ' size *M

autoextend on --autoextend

--There are also some commands that define the size, depending on the needs

default storage(

initial 100K,

next 100k,

);

Example: Creating Tablespaces

create tablespace DEMOSPACE

datafile 'E:/oracle_tablespaces/DEMOSPACE_TBSPACE.dbf'

size 1500M

autoextend on next 5M maxsize 3000M;

Delete Tablespace

drop tablespace DEMOSPACE including contents and datafiles

user rights

Grant users permission to use tablespaces:

alter user username quota unlimited on tablespaces;

or alter user username quota *M on table space;

Complete example:

[sql] view plain copy

--Tablespace

CREATE TABLESPACE sdt

DATAFILE 'F:\tablespace\demo' size 800M

EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;

--Index Tablespace

CREATE TABLESPACE sdt_Index

DATAFILE 'F:\tablespace\demo' size 512M

EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;

--2. Create users

create user demo identified by demo

default tablespace demo;

--3. Empowerment

grant connect,resource to demo;

grant create any sequence to demo;

grant create any table to demo;

grant delete any table to demo;

grant insert any table to demo;

grant select any table to demo;

grant unlimited tablespace to demo;

grant execute any procedure to demo;

grant update any table to demo;

grant create any view to demo;

[sql] view plain copy

--Import Export Command

ip Export Method: exp demo/demo@127.0.0.1:1521/orcl file=f:/f.dmp full=y

exp demo/demo@orcl file=f:/f.dmp full=y

imp demo/demo@orcl file=f:/f.dmp full=y ignore=y
