由于阿里云机房要下架旧服务器，单位未购买整机迁移服务，且业务较老不兼容Oracle11g，所以新购买一台新服务器进行安装Oracle10.2.0.1 ，后续再将数据迁移到新服务器上。

一.迁移前准备
1.1.查询源库信息
1.1.1.查看服务器配置
确保新服务器配置等于或高于旧服务器。
1.1.2.1.查看操作系统版本

1.1.2.1.统计数据量
由于该库数据量较小，该步骤省略。该步骤只适用于数据量大的场景。

需和开发 直属领导同意。对于占用空间大的表采用方案如下：
1、删除表数据。
2、备份时加参数排除，即不备份对业务来说不重要的表。

echo $LANG
export LANG=en_US.UTF-8三.迁移过程
3.1.传输物理文件
主要传输文件参考：
1.数据文件
2.控制文件
3.重做日志文件
4.参数文件
5.监听文件tnsnames.ora listener.ora
6.密码文件PWDfile
直接拷贝oracle目录下的admin、oradata(datafile， controlfile，redo)、flash_recovery_area三个文件夹，db_1目录下database(PWDfile、pfile)、dbs(spfile)、NETWORK/ADMIN(listener.ora、tnsnames.ora)，到其他存储实现备份。
3.1.1.传输参数文件
3.1.1.1.源库传输参数文件至目标库
将源库/home/oracle/initcq_bak_20240607拷贝到目标库的/home/oracle目录。
--源库上操作 传输参数文件
su - oracle
[oracle@cq ~]$ scp initcq_bak_20240607 oracle@120.46.146.123:/home/oracle/由于源库和目标库内存cpu磁盘配置一样，因此参数文件不用更改内存参数，只用改路径就可以了。
3.1.1.2.目标库更改参数文件
参数文件中
*.audit_file_dest='/data/app/oracle/admin/cq/adump' 为$ORACLE_BASE目录/admin/cq/adump
.control_files中control01.ctl、control02.ctl、control03.ctl路径为数据目录/cq/control01.ctl
.db_recovery_file_dest为$ORACLE_BASE目录/fast_recovery_area
.diagnostic_dest为$ORACLE_BASE目录
--目标库操作 备份已传输的参数文件，避免改的有问题重新从源库服务器传输到目标库服务器
[oracle@cqnew:/home/oracle]$ cp initcq_bak_20240607 initcq_bak_20240607_1
--更改参数文件中的oracle_base目录为目标库的oracle_base目录
su - oracle
vi initcq_bak_20240607
:%s#旧目录#新目录#g更改后记得确认，避免更改错误。
注意事项：如果源服务器和目标服务器的内存和cpu配置不一样，需修改内存和cpu方面的参数，内存公式如下：
内存参数修改公式：
--sga和pga配置的最佳实践
对于OLTP系统来说，
--os_memory_total=$(awk '/MemTotal/{print $2}' /proc/meminfo)
--$sga_target=os_memory_total * 8 * 8 / 100 / 1024
--pga_target=os_memory_total * 8 * 2 / 100 / 1024
对于DSS系统来说，oracle建议是sga=系统内存*0.8*0.5 单位字节
pga=系统内存*0.8*0.5

配置免密
#1.本地生成密钥文件(172.17.130.7上操作)
ssh-keygen --全程敲回车
#2.将本地公钥传输到远程主机(172.17.130.7上操作)
ssh-copy-id -i ~/.ssh/id_rsa.pub root@172.17.76.18
#3.测试本地免密登录到远程主机(172.17.130.7上操作,ssh 目标服务器ip)
ssh 172.17.76.18

参数说明：
-z: --compress 使用压缩机制 时间长带宽速度慢，相反时间段带宽速度快
-v: --verbose 打印详细信息
-r: --recursive 以递归模式同步子目录
--progress 实时的显示拷贝进度, 以及传输速率等信息. 尤其是拷贝大文件时, 程序不输出信息, 用户往往无法区分程序是在响应中, 还是已经挂起
-a --archive ：归档模式，表示递归传输并保持文件属性。可以同步元信息（比如修改时间、权限等），比-r更有用
-r --recursive：表示递归，即包含子目录。注意，-r是必须的，否则 rsync 运行不会成功3.4.传输日志文件
