Correlation and long-running question RRS feed

  • Question

  • I have an orchestration that does some processing but needs to wait for a file to be ready in a shared location before it can proceed further. I can use a delay and keep polling until the file is ready and then move on. But the problem is that it is going to be a problem while updating the BizTalk application during deployments.

    If I use correlation, is my case still going to be a long running instance?

  • Hi ,

    you would need to implement sequential convoy pattern here, And also you would be only waiting for a particular amout of time? It is going to be a log running orchestration and before deploying any new release you need to make sure current ones has completed the processing.

    Please see following two articles on sequential convoys using correlation

  • See this blog post get the idea how you can use the side-by-side deployment with convoy, though this post is for BizTalk 2004 but the idea should work for you. And the issue reported in this blog has been fixed in KB911617 for BizTalk 2004 so you should not face this problem.

  • Yes it is still be the LR transaction. It is nothing to do with correlation for your case.

    The problem with updationg of the LR orchestrations are independent problem. You can fight it by broken LR orch to several orchs with state stored in database


    implementing wise versioning strategy in a way new artifacts can work side by side with old one.
