1、创建临时表空间

select name from v$tempfile;查出当前数据库临时表空间，下面创建临时表空间会使用里面的存放路径；

SQL> select name from v$tempfile;

NAME

--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/temp01.dbf

创建临时表空间：使用上面查询到的临时表空间路径

SQL> create temporary tablespace testdb01_temp tempfile '/u01/app/oracle/oradata/orcl/testdb01_temp.dbf' size 100m reuse autoextend on next 20m maxsize unlimited;

Tablespace created

创建临时表空间后检查

SQL> select name from v$tempfile;

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/temp01.dbf
/u01/app/oracle/oradata/orcl/testdb01_temp.dbf

2、创建表空间

select name from v$datafile;查询出当前数据库表空间，下面创建表空间会使用里面的路径

SQL> select name from v$datafile; 

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/system01.dbf
/u01/app/oracle/oradata/orcl/undotbs01.dbf
/u01/app/oracle/oradata/orcl/sysaux01.dbf
/u01/app/oracle/oradata/orcl/users01.dbf
/u01/app/oracle/oradata/orcl/acctdat.dbf
/u01/app/oracle/oradata/orcl/acctidx.dbf
/u01/app/oracle/oradata/orcl/datadat.dbf
/u01/app/oracle/oradata/orcl/dataidx.dbf
/u01/app/oracle/oradata/orcl/fildat.dbf
/u01/app/oracle/oradata/orcl/filidx.dbf
/u01/app/oracle/oradata/orcl/hisdat.dbf

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/hisidx.dbf
/u01/app/oracle/oradata/orcl/userdat.dbf
/u01/app/oracle/oradata/orcl/useridx.dbf
/u01/app/oracle/oradata/orcl/archdat.dbf
/u01/app/oracle/oradata/orcl/archidx.dbf

16 rows selected.

创建表空间：使用上面查询到的表空间路径

SQL> create tablespace testdb01  datafile '/u01/app/oracle/oradata/orcl/testdb01.dbf' size 100M reuse autoextend on next 40M maxsize unlimited default storage(initial 128k next 128k minextents 2 maxextents unlimited);

Tablespace created

 创建临时表空间后检查

SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/system01.dbf
/u01/app/oracle/oradata/orcl/undotbs01.dbf
/u01/app/oracle/oradata/orcl/sysaux01.dbf
/u01/app/oracle/oradata/orcl/users01.dbf
/u01/app/oracle/oradata/orcl/acctdat.dbf
/u01/app/oracle/oradata/orcl/acctidx.dbf
/u01/app/oracle/oradata/orcl/datadat.dbf
/u01/app/oracle/oradata/orcl/dataidx.dbf
/u01/app/oracle/oradata/orcl/fildat.dbf
/u01/app/oracle/oradata/orcl/filidx.dbf
/u01/app/oracle/oradata/orcl/hisdat.dbf

NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/orcl/hisidx.dbf
/u01/app/oracle/oradata/orcl/userdat.dbf
/u01/app/oracle/oradata/orcl/useridx.dbf
/u01/app/oracle/oradata/orcl/archdat.dbf
/u01/app/oracle/oradata/orcl/archidx.dbf
/u01/app/oracle/oradata/orcl/testdb01.dbf

17 rows selected.

3、创建用户并指定表空间

SQL> create user testdb01 identified by testdb01 default tablespace testdb01  temporary tablespace testdb01_temp;

User created

4、赋予用户权限

SQL> grant dba to testdb01;

Grant succeeded

5、设置ORACLE11g登录名和密码不区分大小写

oracle 11g 以前的版本的用户名和密码是不区分大小写的; 
oracle 11g 用户名和密码默认区分大小写，

可更改alter system set sec_case_sensitive_logon=false; 设置改为不区分大小写，

用DBA用户登录执行就好了，修改后立即生效，不用重启数据库实例。
