迁移数据库——复制所有数据文件，启动数据库

数据库版本是：Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production

首先得在目标服务器上面安装数据库软件，参考：/article/8077394.html

复制数据文件等到目标机器（10.10.10.9）上：

[root@db u01]# scp -r root@10.10.10.8:/u01/app/oradata /u01/app
The authenticity of host '10.10.10.8 (10.10.10.8)' can't be established.
RSA key fingerprint is 9d:59:1d:a9:55:99:a8:0b:b7:1e:71:29:3e:f1:4d:b8.
Are you sure you want to continue connecting (yes/no)? y
Please type 'yes' or 'no': yes
Warning: Permanently added '10.10.10.8' (RSA) to the list of known hosts.

配置oracle用户环境变量：

export ORACLE_SID=orcl
export ORACLE_BASE=/u01/app
export ORACLE_HOME=/u01/app/oracle
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=.:$PATH:$HOME/bin:$ORACLE_HOME/bin
umask 022
stty erase ^h

把参数文件spfile转换成pfile，编辑pfile，创建必要的目录，然后nomount数据库：
SQL> startup nomount pfile='/u01/app/oradata/pfile.ora'
SQL> create spfile from pfile='/u01/app/oradata/pfile.ora';
SQL> startup force nomount
SQL> show parameter spfile
SQL> alter database mount;
SQL> show parameter control

SQL> alter database open;
alter database open
