实验：Oracle直接拷贝物理存储文件迁移
实验目的：Oracle直接拷贝物理文件迁移，生产库有类似施工需求，故在实验环境简单验证一下。
实验环境：
A主机：192.168.1.200 Solaris10 + Oracle 11.2.0.1
B主机：192.168.1.186 Solaris10
tar cvf oracle.tar oracle
2.关库，备份参数文件，控制文件，数据文件，临时文件，日志文件
查看各个文件的存放路径：
SQL> show parameter pfile
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string /u01/app/oracle/product/11.2.0
/db_1/dbs/spfileprod.ora
SQL> show parameter control
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
control_file_record_keep_time integer 7
control_files string /u01/app/oracle/oradata/prod/c
ontrol01.ctl, /u01/app/oracle/
flash_recovery_area/prod/contr
ol02.ctl
control_management_pack_access string DIAGNOSTIC+TUNING
SQL> set linesize 160
SQL> col member for a70
SQL> select * from v$logfile;
GROUP# STATUS TYPE MEMBER IS_
---------- ------- ------- ---------------------------------------------------------------------- ---
3 ONLINE /u01/app/oracle/oradata/prod/redo03.log NO
2 ONLINE /u01/app/oracle/oradata/prod/redo02.log NO
1 ONLINE /u01/app/oracle/oradata/prod/redo01.log NO
SQL> select name from v$datafile;
NAME
------------------------------------------------------------------------------------------------------------------------
/u01/app/oracle/oradata/prod/system01.dbf
/u01/app/oracle/oradata/prod/sysaux01.dbf
/u01/app/oracle/oradata/prod/undotbs01.dbf
/u01/app/oracle/oradata/prod/users01.dbf
/u01/app/oracle/oradata/prod/dbs_d_wrnophq.dbf
SQL> select name from v$tempfile;
NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/prod/temp01.dbf
SQL>
此实验环境的参数文件，控制文件，数据文件，联机重做日志文件,均在$ORACLE_BASE目录下，不用单独备份了，实际生产情况下，一般肯定是不在$ORACLE_BASE的路径下，此时需要分别记录好路径并备份这些文件。
3.备份的安装包和所有文件传输到目标机器186
scp oracle.tar 192.168.1.186:/u01/app/ tar xvf oracle.tar
4.等待传输和解压的过程中可以先对新主机做一些配置
4.1新建oracle用户和组
groupadd oinstall groupadd dba useradd -g oinstall -G dba -d /export/home/oracle -m -s /usr/bin/bash -c "oracle user" oracle
4.2配置环境变量 vi ~/.profile
ORACLE_BASE=/u01/app/oracle ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 ORACLE_SID=prod PATH=$PATH:$ORACLE_HOME/bin export ORACLE_BASE ORACLE_HOME ORACLE_SID PATH
使环境变量生效
source ~/.profile
4.3root用户修改/etc/system，添加：
set shmsys:shminfo_shmmax=4294967295 //共享内存字节数(一般设置为物理内存的一半) set shmsys:shminfo_shmmin=1 set shmsys:shminfo_shmmni=200 set shmsys:shminfo_shmseg=200 set semsys:seminfo_semmap=1024 set semsys:seminfo_semmns=2048 set semsys:seminfo_semmni=2048 set semsys:seminfo_semmsl=2048 set semsys:seminfo_semmnu=2048 set semsys:seminfo_semume=200 set semsys:seminfo_semopm=100 set semsys:seminfo_semvmx=32767
重启主机生效配置
sync;sync;sync;reboot
5.至此，所有文件均已经拷贝到新主机
5.1尝试启动数据库

5.2尝试恢复数据库
SQL> recover database; Media recovery complete.
跟踪下recover过程的告警日志

5.3尝试正常打开数据库
SQL> alter database open; Database altered. SQL> select status from v$instance; STATUS ------------ OPEN SQL>
跟踪下open库的告警日志，没有问题。

实际生产环境中的施工，并没有遇到啥问题，很顺利搞定了此次需求 。
