Oracle数据库物理迁移

参考文档：https://www.modb.pro/doc/270

实验环境：redhat 5.5

数据库版本：10.2.0.5

1.在同平台安装相同版本的数据库软件，配置好环境变量，建立相应的目录

需要注意的地方就是，审计目录也需要提前创建好

2.在原库中创建pfile文件，用户打开新库

sqlplus / as sysdba

create pfile='/home/oracle/init.ora' from spfile;

3.关闭原库

停掉应用，关闭数据库

alter system switch logfile;

shutdown immediate

4.拷贝文件到新服务器上

这里我直接将文件全部scp，临时文件是可以不传输的，之后重建

[oracle@oracle10 orcl10]$ scp * 192.168.56.10:/oradata/orcl10
The authenticity of host '192.168.56.10 (192.168.56.10)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes

5.对部分pfile文件参数进行调整

部分报错：启动过程中显示闪回路径问题，直接将闪回参数删除，后期在添加

SQL> startup pfile='/home/oracle/init.ora';
ORA-01261: Parameter db_recovery_file_dest destination string cannot be translated
ORA-01262: Stat failed on a file destination directory
Linux-x86_64 Error: 2: No such file or directory

6.启动数据库，并创建spfile文件

SQL> startup pfile='/home/oracle/init.ora';
ORACLE instance started.
