把AA数据库迁移到BB数据库
1、AA数据库查看用户的默认表空间
select username,default_tablespace from dba_users where username='AA_Username'
2、查看用户的角色
select * from user_role_privs;
3、BB数据库的数据文件所在位置
SQL> select name from v$datafile;
NAME
--------------------------------------------------------------------------------
D:\ORACLE\PRODUCT\10.2.0\ORADATA\CCOMS\SYSTEM01.DBF
D:\ORACLE\PRODUCT\10.2.0\ORADATA\CCOMS\UNDOTBS01.DBF
D:\ORACLE\PRODUCT\10.2.0\ORADATA\CCOMS\SYSAUX01.DBF
D:\ORACLE\PRODUCT\10.2.0\ORADATA\CCOMS\USERS01.DBF
D:\ORACLE\PRODUCT\10.2.0\ORADATA\CCOMS\EXAMPLE01.DBF

4、BB数据库创建用户使用的默认表空间，数据文件自动扩展
SQL> create tablespace BB_default_space
2 datafile 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\CCOMS\BB_default_space.DBF'
3 size 5M autoextend on;
表空间已创建。
5、BB数据库创建新用户
SQL> create user BB_Username
2 identified by BB_Username000
3 default tablespace AA_default_space;
用户已创建。
6、BB数据库授权给新用户
SQL> grant connect,resource,dba to BB_Username;
授权成功。
7、BB数据库配置listener.ora 和 tnsnames.ora
配置ip，以便外面可以访问
listener.ora文件：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = BB_IP)(PORT = 1521))
)
)
tnsnames.ora文件：
BB_Username =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = BB_IP)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BB_Username)
)
)
修改监听器配置文件，需要重新启动监听器
关闭监听器：lsnrctl stop
重启监听器：lsnrctl start
8、在另一个数据库（配置方便使用plsql）配置tnsnames。ora
BB_Username =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = BB_IP)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = BB_Username)
)
)
9、在AA数据库查询用户下都用把数据放到哪些表空间中，建立相应的表空间
select distinct tablespace_name from user_segments
where tablespace_name not in ('USERS','USERS02')
10、生成下面的脚本，用plsql导入到BB数据库中
CREATE TABLESPACE DRILL_LOB_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\TEST_LOB_SPACE.DBF' size 5M autoextend on;
CREATE TABLESPACE DH_LOB_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\_LOB_SPACE DATAFILE.DBF' size 5M autoextend on;
CREATE TABLESPACE TEST_NORM_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\TEST_NORM_SPACE DATAFILE.DBF' size 5M autoextend on;
CREATE TABLESPACE LOG_LOB_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\LOG_LOB_SPACE DATAFILE.DBF' size 5M autoextend on;
CREATE TABLESPACE MLOG_NORM_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\MLOG_NORM_SPACE.DBF' size 5M autoextend on;
CREATE TABLESPACE MLOG_LOB_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\MLOG_LOB_SPACE.DBF' size 5M autoextend on;
CREATE TABLESPACE LOG_NORM_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\LOG_NORM_SPACE.DBF' size 5M autoextend on;
CREATE TABLESPACE HHH_NORM_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\HHH_NORM_SPACE DATAFILE.DBF' size 5M autoextend on;
CREATE TABLESPACE GPE_NORM_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\HHDS_NORM_SPACE DATAFIL.DBF' size 5M autoextend on;
CREATE TABLESPACE HHDS_LOB_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\HHDS_LOB_SPACE DATAFILE.DBF' size 5M autoextend on;
CREATE TABLESPACE PUB_NORM_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\PUB_NORM_SPACE DATAFILE.DBF' size 5M autoextend on;
CREATE TABLESPACE PUB_LOB_SPACE DATAFILE 'D:\ORACLE\PRODUCT\10.2.0\ORADATA\BB_Username\BBII_LOB_SPACE DATAFILE.DBF' size 5M autoextend on;
11、导出AA数据库的数据
exp AA_Username/AA_Password@AA_Database file=F:\AA_Databaseoraclebak\AA_Database14.dump log=F:\AA_Databaseoraclebak\AA_Database14.log
12、导入BB数据库的数据:不需要用户授权权限
imp BB_Username/BB_Password@BB_Database FROMUSER=AA_Username TOUSER=BB_Username ignore=yes grants=no file=F:\AA_Databaseoraclebak\AA_Database14.dump log=F:\AA_Databaseoraclebak\IMP20100121BB_Username.log
