full database export and import(实战)
全库导出，导入实战（数据库版本需相同）
1、全库导出
[ora@dg-ss ~]$ exp system/oracle@test file=/home/ora/full.dmp full=y
2、查看源库的表空间
sys@TEST> select tablespace_name from dba_tablespaces;
TABLESPACE_NAME
------------------------------
SYSTEM
UNDOTBS1
SYSAUX
TEMP
USERS
DOUDOU
3、迁移dmp文件到恢复库
[ora@dg-ss ~]$ scp full.dmp[email protected]:/home/ora
4、恢复库建立表空间（源库与恢复库对比，如需建立表空间，请建立）
建立空间小技巧（源库执行）
永久表空间
select 'create tablespace ' || tablespace_name ||' datafile '''||replace(file_name,'源库数据文件目录/','目的库数据文件目录/') ||'''size 500m autoextend on ;' from dba_data_files ;
临时表空间
select 'create temporary tablespace ' || tablespace_name ||' tempfile '''||replace(file_name,’源库数据文件目录/','目的库数据文件目录/') ||'''size 500m autoextend on ;' from dba_temp_files ;
恢复库
sys@TEST> select tablespace_name from dba_tablespaces;
TABLESPACE_NAME
------------------------------------------------------------
SYSTEM
UNDOTBS1
SYSAUX
USERS
DOUDOU
TEMP
6、全库导入
[ora@dg-pp ~]$ imp system/oracle@test file=/home/ora/full.dmp full=y ignore=y
7、成功后，建议再次全库导出已做备份
附表：
不同版本的全库导入导致了oracle组件出现问题
EXP全库 oracle：10.2.0.1
IMP全库 oracle:10.2.0.4
sys@TEST> select comp_name, version, status from sys.dba_registry;

解决方法：
sys@TEST> shutdown immediate;
sys@TEST> startup upgrade
sys@TEST> @?/rdbms/admin/catupgrd.sql----重新升级组件
sys@TEST> @?/rdbms/admin/utlrp.sql ---重新编译plsql失效的包
sys@TEST> select comp_name, version, status from sys.dba_registry;

总结：full database export and import 需数据库版本相同
