大家好，我是考100分的小小码 ，祝大家学习进步，加薪顺利呀。今天说一说SSIS Catelog中的项目太大导致VS导入项目的时候报错Out Of Memory「建议收藏」,希望您对编程的造诣更进一步.
很苦恼，PROD上的SSIS项目，日积月累的往里部署，加包，也没觉得是个什么问题。
但是今天从需要从PROD上把这个项目中所有的包都down下来，VS居然报错Out Of Memory，无论是直接连接SSIS Catelog或者用SSMS导出ispac均报错。
解决方法很简单，使用PowerShell脚本，直接把ispac download下来然后解压缩，这样里面就直接可以看到.dtsx文件了。
核心就在于参数UnzipIspac，一定要是True，这样执行完成后就能直接看见.dtsx包了。
PS脚本：
