navicat+datax迁移oracle2mysql_datax迁移oracle到mysql

1. 先通过navicat在mysql上建表结构。

使用navicat连接oracle和mysql后，工具 —> 数据传输，源端选择oracle，目标端选择mysql。

2. 通过datax工具迁移数据

2.1 下载安装datax

所需环境：jdk1.8以上，python
下载datax：

wget http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz -C /opt/
tar -xf /opt/datax.tar.gz
cd /opt/datax

2.2 datax相关文件

其中bin/datax.py为程序主文件，不需要修改
job下json文件需要手动修改配置，可参考官方文档：https://github.com/alibaba/DataX/blob/master/

可以用命令直接执行：

python2 /opt/datax/bin/datax.py -p "-Dtablename=test_table" /opt/datax/job/oracle2mysql.json

也可以通过脚本调用：

[root@host124 datax]# cat tablename.txt 
test_table1
test_table2
test_table3
