一、同步情况方向
源端ORACLE11.2.0.4 RAC--同步-》目标端DM V8.1.3.62_pack16 DSC
二、使用的同步软件版本
达梦端HS版本：V4.3.24-Build(2023.11.04-143714trunc)_D64_2311
ORACLE端HS版本：V4.3.14-Build(2023.07.05-133910trunc)_D64_2306_sp9
三、问题表现

正常运行一段时间后，发现源端会异常停止，且无法启动

前台方式启动同步，启动后直接CORE掉

分析对于的CORE文件，通过堆栈显示，关键#5行是“redo_parse_get_data_piece”出现异常，与技术专家沟通，基本确认与“redo解析”有关。

四、解决办法
升级ORACLE端的hs版本与DM端一致，即V4.3.24，完美解决本次故障，正常启动hs。

五、总结
对于DMHS同步环境，部署的时候源端和目标端版本务必一致，例如本次统一使用V4.3.24即可减少此类问题出现。
