Help on Biztalk Throtlling

    Question

  • Hi,

    I am analysing throttling condition in one of the applications for Biztalk 2010.

    This is basically an banking application where in morning the message requests are high then in afternoon  the requests are less and in evening they are much less.

    I need suggestions so that throttling can decrease, for example :

    1,  Decreasing the value of Maximum number of messaging engine threads per CPU (found in Advanced Tab --- Host Properties dialog box) can   result in a net gain in throughput.

    2, Using Parallel in orchestrations can decrease throttling.

    Please suggest me what Biztalk 2010 settings can be modified in order to decrease the throttling condition.

  • Can you clarify a bit?

    Are you experiencing Throttling?  If so what kind?  You can check the Throttling Performance Counters: https://msdn.microsoft.com/en-us/library/aa578302.aspx?f=255&MSPPError=-2147217396

    Or are you trying to throttle you app, meaning smooth out the processing over the day?

  • Out of the box, BizTalk will always favor receive operations to maintain availability with upstream systems so there is not automatic Throttling in that area. It's important to know exactly what Throttling is happening and for that, you need to look at the Perf Counters during a Throttling state. http://msdn.microsoft.com/en-us/library/aa578302.aspx It's most likely you hitting the High In-Process Message Count. Start here: http://msdn.microsoft.com/en-us/library/cc296779(v=bts.10).aspx That article describe the common scenarios and provides some guidance on what to adjust and in what circumstances. Try following: - If possible have 64 bit Orchestration host - Change Resource-Based Throttling of orchestration host Memory Usuage->Process Virtual to adjust based on available memory - Change Rate-Based Throttling , Publising and Delivery->Maximum Throtting Delay to 0 and Throttling override to "Do not throttle" Please note, after these changes host not will not throttle and your memory usage can go beyond and in those condition your host will restart. The actual setting depends on your volume and other load on the servers

  • You should get more insight in to what type of throttling you have, and which components in your BizTalk setup that is causing this. Is it due to high throughput? Big messages? Parallel processing? SQL perf issue?

    Based on that info you can take action. Modifying values in the BizTalk without knowing the reason is never a good idea, will in the best case be a temp solution.

    You can try a free performance monitoring tool from my company AIMS that will give you all this insight. You can drill down to any component in your BizTalk and SQL for detailed info on performance and throttling. Take a look at http://www.aimsinnovation.com/aims-free
