SSIS Catelog中的项目太大导致VS导入项目的时候报错Out Of Memory

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:
