客户环境概览
2结点RAC（旧）
共享存储（旧）
2结点RAC（新）
共享存储（借用，中转数据使用，用完后需归还）
实施方案：
由于只更换服务器不更换共享存储，所以需要先在新服务器+新共享存储上搭建完RAC环境，导入原库中的数据，再将存储更换为*享存储。
采取该方案的原因如下：
新机器操作系统最低只支持RHEL6.5，而原机器操作系统为RHEL5.5，数据库版本Oracle 10g。新机器6.5的RHEL上无法安装Oracle 10g，最低只能安装Oracle11g，因此排除添加删除节点的方案。而且先将原rac升级到11g然后再增删结点的方案需要更长的回退时间，遂也未采用。
实施流程概览
1、为新服务器安装RHEL 6.5以及Oracle 11g GI和Database（OCR使用借用的临时共享存储）；
2、停止应用和旧数据库监听，expdp导出数据；
3、impdp恢复数据到11g rac环境；
4、将应用连接到新数据库环境，进行简单连通性测试以及验证数据完整性；
5、关闭应用，卸载老存储并格式化分为300G一个的LUN，映射到新服务器上；
6、在*享存储上创建asm磁盘组，迁移OCR以及voting disk至老存储
7、使用rman（backup as copy）将数据库迁移到老存储；
8、启动数据库，并启动应用，进行测试；

opatch为GI和DB软件打补丁:
export PATH=$PATH:$ORACLE_HOME/OPatch
执行$ORACLE_HOME/OPatch/ocm/bin/emocmrsp生成ocm.rsp文件
然后使用opatch auto /tmp/23274134 -ocmrf /tmp/ocm.rsp为GI打补丁
注意：如果已经建库opatch会自动为DB软件打补丁，如果未建库DB的补丁要自己手动打。

dbca建库
建库过程中警告日志出现如下警告
Thread 1 cannot allocate new log, sequence 21
Checkpoint not complete

后期要添加在线日志组，日志组成员大小为500MB
2016年7月21日21:10:00
expdp DIRECTORY=DMPDIR DUMPFILE=all.dmp LOGFILE=all.log SCHEMAS=TSMSYS,CENTER_MAIL,OUTLN,BENTER_ADMIN,WMSYS,CENTER_ETL,GYAM,DDS
数据泵开始从源库导出数据
2016年7月21日21:53:16
准备添加日志组的脚本：
ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 5 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 6 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 7 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 8 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 9 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 1 GROUP 10 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 11 SIZE 500M;
ALTER DATABASE ADD LOGFILE THREAD 2 GROUP 12 SIZE 500M;
删除旧的日志组(删除前要switch logfile以确保删掉的日志组不是current状态)：
ALTER DATABASE DROP LOGFILE GROUP 1;
ALTER DATABASE DROP LOGFILE GROUP 2;
ALTER DATABASE DROP LOGFILE GROUP 3;
ALTER DATABASE DROP LOGFILE GROUP 4;
创建表空间并添加相应数据文件：
CREATE TABLESPACE CENTERDBT DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE CENTERDBT ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
CREATE TABLESPACE GYDB DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
ALTER TABLESPACE GYDB ADD DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
CREATE TABLESPACE CENTERMAIL DATAFILE SIZE 1G AUTOEXTEND on next 100m;
CREATE TABLESPACE SPACE_INXITEDB DATAFILE SIZE 1G AUTOEXTEND ON next 100m;
运行hugepages_settings.sh得出大内存参数
vm.nr_hugepages = 2052
vm.vfs_cache_pressure=200
vm.swappiness=10
vm.min_free_kbytes=524288

expdp导出完成
2016年7月22日00:14:26
添加日志组
创建相应表空间并添加数据文件
2016年7月22日01:15:37
导入开始
impdp system/oracle DIRECTORY=dmpdir DUMPFILE=all.dmp LOGFILE=in.log CLUSTER=N &
状况：发现字符集不对，原库用的GBK，新库用的UTF8，遂DBCA删除重建。（耗时大约15分钟）
2016年7月22日02:56:57
再次进行impdp操作
2016年7月22日07:23:58
最终由于导入速度过慢，无法再8点之前完成导入操作（3小时导入100多G），客户要求终止新rac的导入，并重新启用旧rac。暂定于周五继续进行迁移操作。
