3 创建配置文件

vim /opt/module/datax/job/oracle2mysql.json

{
	"job": {
		"content": [{
			"reader": {
				"name": "oraclereader",
				"parameter": {
					"column": ["*"],
					"connection": [{
						"jdbcUrl": ["jdbc:oracle:thin:@192.168.222.133:1521:orcl"],
						"table": ["handsome"]
					}],
					"password": "123456",
					"username": "atguigu"
				}
			},
			"writer": {
				"name": "mysqlwriter",
				"parameter": {
					"column": ["*"],
					"connection": [{
						"jdbcUrl": "jdbc:mysql://192.168.222.132:3306/oracle",
						"table": ["handsome"]
					}],
					"password": "123456",
					"username": "root",
					"writeMode": "insert"
				}
			}
		}],
		"setting": {
			"speed": {
				"channel": "1"
			}
		}
