SQL Server维护计划任务和完成

maintenance-plan ssis concurrency sql-server

Bennett Dill · 技术社区 · 14 年前

我有一个维修计划,看起来像这样…

Client 1 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client
Client 2 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client
Client N ...

导入数据和进程数据正在调用作业,后处理是一个执行SQL任务。如果导入数据或进程数据失败,它将转到下一个客户端导入数据…

导入数据和进程数据都是包含使用内置SQL日志记录提供程序的SSIS包的作业。

我对现有配置的期望是:

客户端1导入数据运行:失败->客户端2导入数据成功处理数据
进程数据运行:失败->客户端2导入数据成功发布进程
后期处理运行:完成->成功或失败->下一个客户端导入数据

但这不是我在日志中看到的… 我看到几个客户机导入数据SSIS日志条目,然后是几个后处理日志条目,然后返回到客户机导入数据!啊!!

我做错什么了?我不认为客户端1导入数据的“成功”部分会启动,直到它…好。。。成功,又名完成!不过,日志上似乎另有说明…

我真的需要这些任务是连续的而不是并发的。这有可能吗?

谢谢!

尝试在需要分组执行的任务周围放置序列容器。

对于我来说,解决方法最终不是使用内置的“执行SQL Server代理作业任务”,而是使用“执行T-SQL语句任务”,并调用一个在完成前被阻止的存储过程…
