机器准备

• node1

ip：10.10.200.84
hostname：node1
desc：迁移前机器

• node2

ip：10.10.200.49
hostname：node2
desc：迁移后机器

Oracle 11g 安装 node1

源 Oracle 数据准备 进入 oracle 用户

[root@node1 ~]# su - oracle
Last login: Wed Oct 20 14:39:42 CST 2021 on pts/0

查看监听器状态

[oracle@node1 ~]$ lsnrctl status

sysadmin 连接

[oracle@node1 ~]$ sqlplus / as sysdba

创建表空间

# 目录 -- /home/data/v1.3/oracle
SQL> CREATE TABLESPACE test_oracle_move DATAFILE '/home/data/v1.3/oracle/oradata/orcl/test_oracle_move.dbf' SIZE 50M AUTOEXTEND ON NEXT 50M MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL;

Tablespace created.

创建用户

# 用户创建 -- jhemr/xxxxx
SQL> CREATE USER jhemr IDENTIFIED BY xxxxx DEFAULT TABLESPACE test_oracle_move;

User created.

用户授权

# 授权 -- 最大（仅限临时测试）
SQL> GRANT CONNECT, RESOURCE, DBA TO jhemr;

Grant succeeded.

写入数据

# 通过 select 创建
SQL> create table copy_emp as select * from scott.emp;

Table created.

查看表信息

# 查看数据量
SQL> select count(*) from copy_emp;

  COUNT(*)

Oracle 文件迁移 准备

• node1 关闭 oracle 服务

# 连接
[oracle@node1 ~]$ sqlplus / as sysdba

# 关闭 oralce
SQL> shutdown immediate;

• node1 关闭监听

[oracle@node1 ~]$ lsnrctl stop

• node2 关闭 oracle 服务

# 连接
[oracle@node2 ~]$ sqlplus / as sysdba

# 关闭 oralce
SQL> shutdown immediate;

• node2 关闭监听

[oracle@node2 ~]$ lsnrctl stop

文件拷贝

• node2

# 备份原有目录
[oracle@node2 ~]$ mv /data/v1.3/oracle /data/v1.3/oracle_bak

• node1

# 拷贝整个目录
[root@node1 ~]# scp -r /home/data/v1.3/oracle root@10.10.200.49:/data/v1.3/oracle

node2 配置

• 权限配置

# node1 scp 使用 root -- 需改成 oracle 启动权限
[root@node2 ~]# chown -R oracle.oinstall /data/v1.3/oracle

• 监听文件配置

# 更改前 -- node1
[root@node2 ~]# cat /data/v1.3/oracle/product/11.2.0/network/admin/listener.ora | grep node
      (ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1521))

# 更改后 -- node2
[root@node2 ~]# cat /data/v1.3/oracle/product/11.2.0/network/admin/listener.ora | grep node
      (ADDRESS = (PROTOCOL = TCP)(HOST = node2)(PORT = 1521))

Oracle 启动 启动监听

[root@node2 ~]# su - oracle
Last login: Wed Oct 20 15:25:55 CST 2021 on pts/0
[oracle@node2 ~]$ lsnrctl start

连接 oracle

[oracle@node2 ~]$ sqlplus / as sysdba
