hp-ux利用rman将数据库跨平台迁移到aix平台上

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.

  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;

2.3.2 用system用户和密码进行登录来验证

SQL> conn system/ufgov
Connected.

可以登录
2.3.3 表空间验证,查询迁移后的表空间及文件

SQL> select tablespace_name,file_id from dba_data_files;

TABLESPACE_NAME                   FILE_ID
------------------------------ ----------
ZWDATA                                  6
ZWDATA                                  5
USERS                                   4
SYSAUX                                  3
UNDOTBS1                                2
SYSTEM                                  1

6 rows selected.

2.3.4 对数据库进行DML操作验证

SQL> create table test (i int);

Table created.

SQL> insert into test values (1);

1 row created.

SQL> select * from test;

         I
----------
         1

SQL> delete from test;

1 row deleted.

SQL> drop table test;

Table dropped.

2.3.5 切换日志测试

SQL> alter system switch logfile;

System altered.

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
