oracle的clone及冷迁移（直接拷贝数据文件）
时间:2014-09-06 07:09:23 作者:beebol 标签: oracle clone 冷迁移 分类: Oracle
最近做了个oracle 10g数据冷迁移，很简单，但还是写一下基本的操作过程：
首先是准备迁移目标服务器，初始化环境，安装数据软件。
基本的环境初始化、依赖包先安装好、相关目录、用户都需要安装好（目标机器环境要与原一样），安装数据库软件我是采用的clone，将线上的product目录打包传到目标服务器。
内存检查
grep MemTotal /proc/meminfo MemTotal: 32949816 kB
磁盘空间检查
df -k /dev/shm/ Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 16474908 0 16474908 0% /dev/shm df -h /tmp Filesystem Size Used Avail Use% Mounted on/dev/shm 16G 0 16G 0% /tmp /dev/shm 16G 0 16G 0% /tmp
内核检查
uname -r2.6.18-194.el5 2.6.18-194.el5
依赖包检查
rpm -q \ binutils \ compat-libstdc++-33 \ elfutils-libelf \ elfutils-libelf-devel \ gcc \ gcc-c++ \ glibc \ glibc-common \ glibc-devel \ glibc-headers \ ksh \ libaio \ libaio-devel \ libgcc \ libgomp \ libstdc++ \ libstdc++-devel \ make \ numactl-devel \ sysstat \ unixODBC \unixODBC-devel | grep "not installed" unixODBC-devel | grep "not installed"
创建用户
groupadd oinstall groupadd dba chattr -i /etc/passwd /etc/shadow useradd -g oinstall -G dba oracle passwd oracle chattr +i /etc/passwd /etc/shadow
目录创建、环境参数修改等

ulimit -p 16384
ulimit -n 65536

vi .bash_profile

开始打包原服务器oracle软件
[@crm.cyou.com product]# pwd /U01/app/oracle/product[@crm.cyou.com product]# tar -zcf 10.2.0.tgz 10.2.0 [@crm.cyou.com product]# tar -zcf 10.2.0.tgz 10.2.0
拷贝到目标服务器，解压，开始clone
cd $ORACLE_HOME/clone/bin/
perl clone.pl ORACLE_BASE=/U01/app/oracle ORACLE_HOME=/U01/app/oracle/product/10.2.0 ORACLE_HOME_NAME=db_1
./runInstaller -clone -waitForCompletion "ORACLE_BASE=/U01/app/oracle" "ORACLE_HOME=/U01/app/oracle/product/10.2.0/db_1" "ORACLE_HOME_NAME=db_1" -silent -noConfig -nowait

WARNING:A new inventory has been created in this session. However, it has not yet been registered as the central inventory of this system.
To register the new inventory please run the script '/U01/app/oracle/oraInventory/orainstRoot.sh' with root privileges.
If you do not register the inventory, you may not be able to update or patch the products you installed.
The following configuration scripts need to be executed as the "root" user.
/U01/app/oracle/oraInventory/orainstRoot.sh
/U01/app/oracle/product/10.2.0/db_1/root.sh
To execute the configuration scripts:
1. Open a terminal window
2. Log in as "root"
3. Run the scripts
The cloning of db_1 was successful.
Please check '/U01/app/oracle/oraInventory/logs/cloneActions......PM.log' for more details.
9.run sh scripts
[root@bf_test_qd_119 ~]# /U01/app/oracle/oraInventory/orainstRoot.sh

这个clone很快，ok后，可以停原oracle实例及监听
select distinct username from v$session; 查看应用是否停完 下面停掉所有监听 lsnrctl stop LISTENER lsnrctl stop LISTENER1532 lsnrctl stop LISTENER1528lsnrctl stop LISTENER1525 lsnrctl stop LISTENER1525
停数据库
shutdown immediate //确定应用停完后，开始停数据库
开始拷贝数据文件
scp -r /U01/app/oracle/product/10.2.0/dbs/* 1.1.1.1:/U01/app/oracle/product/10.2.0/dbs/ scp -r oradata/ 1.1.1.1:/U01/app/oracle/ cd /U01/app/oracle/admin/ldjbmdb && mkdir -p adump bdump cdump dpdump pfile udump utl_filecd /U01/app/oracle && mkdir -p arch flash_recovery_area oraInventory cd /U01/app/oracle && mkdir -p arch flash_recovery_area oraInventory
需要拷贝的包括如下：
1、控制文件
2、数据文件
3、参数文件spfile (环境一致)
4、密码文件
5、redo
没有首先检查这些文件的路径，然后再进行拷贝，这里我的目录基本都没有变，控制文件、数据文件、redo都 在oradata里，密码文件、参数文件都在dbs目录里。所以我只要拷贝两个目录就行。
然后就创建相应的目录，启动数据库
startup mount; alter database archivelog; alter database open; archive log list; ALTER DATABASE FORCE LOGGING; select log_mode,force_logging from v$database; 启监听 lsnrctl start LISTENER lsnrctl start LISTENER1532 lsnrctl start LISTENER1528lsnrctl start LISTENER1525 lsnrctl start LISTENER1525
把数据库开启了archivelog（选择冷迁移的原因就在这里）
后面还有些步骤就是：
a.检查计划任务
b.防火墙
c.数据库自启动
