Hi,
Rehyderation and dehyderation of Orchestration instance is much more necessary in pub sub architecture on which BizTalk is build.
I would not suggest to change anything on this part. You are try changing The MaxReceiveInterval from adm_service(BizTalk Management DB) but it may cause you race condition for messages published to the mesagebox .
You can also try creating multiple host instances for processing ,receiving and sending messages in/out of BizTalk .If your environment is taking much more time then try running messagebox viewer to see any inconsistency in biztalk databases
Thanks

Hi
There are ways to modify the dehydration behavior, but it's not worth it for the trouble it can cause if not done judiciously. Why are you looking to prevent the dehydration? Are there strict latency requirements for the scenario?
Thanks

Thank you for your reply Abhishek and Arindam,
we want our orchestration send 8 web request at a time. So we used maximum worker throat to 8 in Host Instance .NET CLR. What we observed is, 8 orchestrations are active at a time. However, these orch dehydrate for few sec and more orchestration become active to keep the 8 throats. As a result more requests are hitting the web service at a time. Is it possible to keep the orch active until it completes or for few sec? This orche runs on its on host
You can increase the Minimum Threshold for Orchestration Throttling for your Host from the default of 1sec. But beware, this is potentially dangerous because this affects all orchestrations in that host and may lead to memory issues.
Maybe you can try and control the number of active Send Port instances using the Dispenser pattern - that's a much cleaner approach-

My first bit of advice is don't worry about it. Seriously.
You didn't describe any actual problem with this, just as a observation. This is how BizTalk works.
Second, while you can adjust some settings, you likely won't see a measurable difference it at all. Since there is a Persistence Point on the Send Port anyway, the Dehydration cycle is almost incidental.
So, unless you can prove a specific problem, such as not meeting an SLA, don't do anything.
Hi ,
There is no need to change Maximum Worker Threads to 8 (by default it is 100) .Let Biz Talk handle current threads .If you are changing the WT to a minimum number like 8 then there is always a case were multiple request are awaiting in Queue for the processing .
You can try using maxconnection setting in BTSNTSvc.exe.config .

So, this should not be marked as a Proposed Answer. This has nothing to do with the question asked.There is no need to change Maximum Worker Threads to 8 (by default it is 100) .Let Biz Talk handle current threads .If you are changing the WT to a minimum number like 8 then there is always a case were multiple request are awaiting in Queue for the processing .

Thank you Abhishek,
I allready have separate host for orchs. I was sharing the send port host with others. I will create separate one for send port and check it.
Thank you Guys, all of your advise are helping a lot.
Problem with my solution is, vender is complaining we are sending too many web connection call at a time. As you advise, i will check send port and max connection set up to see if i can bring down the num of connections. We have 4 BTS servers (total 32 cpu). It looks like vender's system is not that rich and cannot handle over 32 connection at atime. We dont want to stop hosts in some server to control the connection calls since we need load balance and not to over load one server than other.
Hi WatNxt,
Can you please try with the below setting in the BizTalk confile btsntsvc.exe.config and btsntsvc64.exe.config? You can replace address="*" with the specific url of the vednor web service.
<system.net>Cheers

Hi WatNxt,
So, that's a completely different scenario and isn't related, BizTalk-wise, to you observed dehydration.
This is, unfortunately, a very common scenario.
The easiest solution is setting Ordered Delivery on the Send Port. This will essentially serialize calls to the external app. While that might be too slow, it will work.
Did you try maxWorkerThreads? That will affect the outbound connections as well, although not as granularly as you may need.
Yes, i used Maxworkerthreads and ordered delivery on send port. I see below issues.
1. i used same (1) maxworkerthreads on Orchestration host and send port host (without order delivery). Soft req/res port has Delivery Notification = Transmitted in orchestration. I see alot of warning messages in application event view complains not enough threads to transmit the request. Event log get filled with below..and hard for support team if they need event log for other failurs.
The adapter failed to transmit message going to send port "****" with URL "******". It will be retransmitted after the retry interval specified for this Send Port. Details:"System.InvalidOperationException: There were not enough free threads in the ThreadPool to complete the operation.
2. If i use above setting with Order delivery ON on send port then i see request are going from only one server. I guess because it is singleton now. We are running 3 servers and want to distribute the load across the servers. Since send port stay active forever in this case, it looks like it will use same server to send/receive web request until it got terminated. Since servers are used by other apps...this setting may overload one server where send port runs. If send port become active on receiving requst and goes away after completing the pool, then it may choose different server based on the available resource. But it is active forever on one server and it is going to use same server here. doesnt look good. is there any way to handle this?
The most correct BizTalk way to achieve what you're looking for is with a Resource Dispense Pattern.

Thank you John, we are going to use .net app to handle send part so we can easly control thread and load balance.
Thank you so much for your help.
Please trust us, you really don't need to do that, meaning the out-of-band solution.
All the these issues have been addressed many times.
If you have any specific issues, feel free to open a new thread.
