建立表空間：

- drop tablespace user_temp  including contents and datafiles; 

- drop tablespace user_data including contents and datafiles; 
- drop tablespace user_index including contents and datafiles;
- drop user c##amap cascade;
- drop user amap cascade;
- create temporary tablespace user_temp tempfile 
autoextend on next 20m maxsize unlimited;
- create tablespace user_data datafile 
autoextend on next 40m maxsize unlimited;
- create tablespace user_index logging datafile 
autoextend on next 32m maxsize 2048m extent management local;

create user c##amap identified by amap default tablespace user_data temporary tablespace user_temp ;

create user amap identified by amap default tablespace user_data temporary tablespace user_temp;

- grant dba to amap;

- grant connect to amap;
- grant resource to amap;
- grant unlimited tablespace to amap;

imp amap/amap@amap file=/opt/oracle/0430.dmp full=y

select status,instance_name from v$instance;

1.登入伺服器，切換到oracle使用者，或者以oracle使用者登入

[admin@dataserver ~]$ su - oracle

[oracle@dataserver ~]$

[oracle@localhost ~]$ lsnrctl start

複製**

[oracle@localhost ~]$ sqlplus /nolog
