开发那边有台Linux 32位服务器因为网卡问题，准备把数据库迁移到一台新服务器(Linux 64)上。因为是开发环境(对稳定性要求不是非常高，停机时间几乎没有要求)，还有我比较懒，准备两边安装相同版本，打上相同的补丁，然后直接拷贝datafile/redo/controlfile/spfile的方法完成数据文件迁移
一、源端信息

--系统信息
[oracle@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.18-194.el5PAE #1 SMP Tue Mar 16 22:00:21 EDT 2010 i686 i686 i386 GNU/Linux
--数据库信息
[oracle@localhost ~]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 15 13:38:51 2011
Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.
Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

二、目标端信息

--操作系统信息
[oracle@gongantest ~]$ uname -a
Linux gongantest 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:14 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
--数据库信息
[oracle@gongantest ~]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 15 13:43:14 2011
Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.
Connected to an idle instance.

三、迁移数据库
1.修改目标库ORACLE_SID变量等环境变量
2.目标库建立相关目录(参考源库)
3.使用shutdown immediate关闭源库
4.拷贝spfile和oradata中文件

四、启动目标端数据库

[oracle@gongantest gaxt]$ sqlplus / as sysdba
SQL*Plus: Release 10.2.0.4.0 - Production on Thu Dec 15 12:46:19 2011
Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.
Connected to an idle instance.
SQL> startup
ORACLE instance started.
Total System Global Area 1526726656 bytes
Fixed Size                  2084136 bytes
Variable Size             369099480 bytes
Database Buffers         1140850688 bytes
Redo Buffers               14692352 bytes
Database mounted.
Database opened.

五、收集系统统计信息

SQL> exec dbms_stats.delete_system_stats();
BEGIN dbms_stats.delete_system_stats(); END;
*
ERROR at line 1:
ORA-06553: PLS-801: internal error [56319]

六、重新编译对象

SQL> shutdown immediate;
SQL> startup upgrade;
SQL> @?/rdbms/admin/utlirp.sql
SQL> @?/rdbms/admin/utlrp.sql
SQL> shutdown immediate;
SQL> startup;

七、出现ORA-07445[_intel_fast_memcpy.J()+250]错误

--alert日志
Thu Dec 15 13:07:22 2011
Errors in file /opt/oracle/admin/gaxt/udump/gaxt_ora_13898.trc:
ORA-07445: exception encountered: core dump [_intel_fast_memcpy.J()+250] [SIGSEGV] [Address not mapped to object] [0x2BA0E731928F] [] []
--trace文件

Current SQL statement for this session:

     rc sys_refcursor;

MEASURE AWOWNER FROM sys.awmd!CAT_AWOWNER
                        MEASURE AWNAME FROM sys.awmd!CAT_AWNAME
                        MEASURE COL5 FROM sys.awmd!CAT_CATALOG_ID
                        MEASURE COL1 FROM sys.awmd!CAT_MEASFOLDERNAME
                        MEASURE COL2 FROM sys.awmd!CAT_MEASFOLDERDESC
                        MEASURE COL4 FROM sys.awmd!CAT_PARENTFOLDERNAME
                        DIMENSION AWMDKEY FROM sys.awmd!AWMDKEY_CAT');
   end;

查看MOS，发现 Oracle OLAP AWs(Analytical Workspace)在迁移过程中没有正确处理导致，不过该功能该库中没有使用到，直接忽略

八、查询组件是否都正常

SQL> col comp_name for a40
SQL> SELECT COMP_NAME,STATUS FROM DBA_REGISTRY;
COMP_NAME                                STATUS

OLAP Analytic Workspace                  VALID

九、收集系统信息

SQL> exec dbms_stats.gather_system_stats(gathering_mode => 'START');
PL/SQL procedure successfully completed.
--一段时间后
SQL> exec dbms_stats.gather_system_stats(gathering_mode => 'STOP');
PL/SQL procedure successfully completed.
