这次因为要迁移的数据库大小并不大但也不是只有几十G所以选择使用rman将生产数据库从hp-ux迁移到aix上，数据库是10.2.0.4
1.操作环境
1.1 源生产环境
数据库名 CAIWU
实例名 CAIWU
DBID 338270341
数据库 HP-UX 10.2.0.4.0 – 64bit Production
数据文件目录 /cwjc_data/CAIWU
文本初始化参数文件:/oracle/product/10.2.0/dbs/init/initCAIWU.ora
1.2 目标生产环境
数据库名 CAIWU
实例名 CAIWU
DBID 338270341
数据库 HP-UX 10.2.0.4.0 – 64bit Production
数据文件目录 /yl_oradata/CAIWU
文本初始化参数文件:/oracle/product/10.2.0/db_1/dbs/init/initCAIWU.ora
2 备份
2.1 备份注意事项
1. 迁移库只能在同字节顺序平台之间(即ENDIAN_FORMAT相同)且得是ORACLE所支持的平台，可以在V$TRANSPORTABLE_PLATFORM中查看。
2. 传输前需要将源库置为只读。
3. 生成的2个脚本文件要仔细根据需要修改。
2.2 源库操作
2.2.1 将库只读，并检查是否支持迁移
一．将库只读，并检查是否支持迁移

2.2.3 利用dbms_tdb 包检查数据库
二．利用dbms_tdb 包检查数据库能否被传输以及列出外部表和DIRECTORY 等无法传输的对象信息，
分别在hp-ux平台数据库通过SQLPLUS执行以下两个存储过程
SQL> set serveroutput on
SQL> declare
2 db_ready boolean;
3 begin
4 /* db_ready is ignored, but with SERVEROUTPUT set to ON any
5 * conditions preventing transport will be output to console */
6 db_ready := dbms_tdb.check_db('AIX-Based Systems (64-bit)',
7 dbms_tdb.skip_none);
8 end;
9 /
PL/SQL procedure successfully completed.
SQL> declare
2 external boolean;
3 begin
4 /* value of external is ignored, but with SERVEROUTPUT set to ON
5 * dbms_tdb.check_external displays report of external objects
6 * on console */
7 external := dbms_tdb.check_external;
8 end;
9 /
The following directories exist in the database:
SYS.DUMP_CAIWU, SYS.DATA_PUMP_DIR, SYS.WORK_DIR, SYS.ADMIN_DIR, SYS.ORACLE_OCM_CONFIG_DIR

小结
1. 确保源库与目标数据库的字符集一致
2. 要确保源库与目标数据库的字节编码相同
3. 数据库迁移后要把无效的数据库对象重新编译，确保正确执行utlrp.sql,utlirp.sql
4. 数据库迁移后，确保应用系统用户可以正确连接，登陆有效
5. 监听要重新配置，检查临时表空间的属主与可用性
6. 迁移完成后要立即进行一次全备份
既然是同样的字节顺序，直接RMAN备份，恢复到新服务器上，行不？
不行同样的字节顺序，但是平台不一样还是需要转换
