[root@db1 config]# 这次实验中，为了避免出现上次的问题，在开启库和表的CDC功能的时候，不要把自动生成的capture和clean作业删除，capture和clean作业只在开启第一个表的CDC的时候会自动创建，后面开启第二个开始就不会再创建了，切记不要删除，否则会出现同样的情况。

50000细心的你已经发现了，在目标端查询表名字的时候如果不加双引号，无法识别到表名字，需要加双引号才能识别到表名字。正常情况下在Oracle存储的表名字均显示大写，现在我们看到表名字与源端保持一致，有大小写，原因应该是seatunnel的配置文件中 ，目标端表名字了加了双引号。
以下让AI生成了一批DML测试语句
执行 INSERT 新增测试数据
USE [AMDBdatabase];

-- 5. 修改订单明细
UPDATE dbo.OrderDetail
SET Quantity = 2,
UnitPrice = 109.90,
LineAmount = 219.80
WHERE DetailID = 990005;
GO执行 DELETE 删除测试
USE [AMDBdatabase];
GO

DELETE FROM dbo.OrderDetail

DELETE FROM dbo.OrderInfo

DELETE FROM dbo.CustomerInfo

-- 4. 删除商品
DELETE FROM dbo.ProductInfo
WHERE ProductID = 990003;
-- 5. 删除员工
DELETE FROM dbo.EmployeeInfo
WHERE EmployeeID = 990002;
GO验证 SQL Server 端测试结果
USE [AMDBdatabase];
GO
SELECT * FROM dbo.CustomerInfo WHERE CustomerID = 990001;
SELECT * FROM dbo.EmployeeInfo WHERE EmployeeID = 990002;
SELECT * FROM dbo.ProductInfo WHERE ProductID = 990003;
SELECT * FROM dbo.OrderInfo WHERE OrderID = 990004;
SELECT * FROM dbo.OrderDetail WHERE DetailID = 990005;
GO验证 Oracle 端实时同步.

seatunnel DML同步数据的统计信息
前面的步骤中，可以通过启动任务时指定的日志文件tail -100f /seatunnel_3.0/apache-seatunnel-3.0.0/logs/demo_mssql_2_oracle_mutitable.out 查看到统计信息，但是无法统计到insert ,update ,delete分别做了多少操作，只是一个总数。

***********************************************待验证功能
建议下一步再验证 4 个生产环境关键场景
- 断点续传：停止 SeaTunnel 作业，再启动，确认不会遗漏变更。
- 持续运行：连续执行大量 INSERT、UPDATE、DELETE，观察同步延迟和任务稳定性。
- 数据库重启：分别重启 SQL Server 或 SeaTunnel Engine，确认作业能够恢复。（重启SQL server数据库之后，同步任务没有中断）
- CDC 清理与磁盘增长：观察 SQL Server CDC 捕获作业、清理作业、事务日志及 CDC 变更表的增长情况。
预留问题：
针对目标表名字大小写的问题，目前未找到解决方法，seatunnel的配置文件无法针对多个表进行大写的自动转换，有一个变通的解决方法是在启动同步任务前，手工在目标库创建目标表名字。
