Sample Dehydration Calculation

Here is an example of a sample calculation, using private bytes, to determine if BizTalk will dehydrate or not. It uses the default configured values, and some example run-time values.

Assume the following values for the dehydration properties:

• TimeBlocked = 60 (example time blocked in seconds)

• WaitingHistory = 90 (example waiting history in seconds)

• ActualPrivateBytes = 250 (example value for private bytes)

• OptimalUsage = 50 (default configuration value)

• MaximalUsage = 350 (default configuration value)

  Since the ActualPrivateBytes are between OptimalUsage and MaximalUsage, alpha is calculated as:

alpha(private) = (350 – 250) / (350 – 50)  
alpha(private) = 100 / 300  
alpha(private) = 0.33  

Then you calculate the TestThreshold as follows:

TestThreshold = 1 + (0.33 * (1800 – 1))  
TestThreshold = 1 + 599.66  
TestThreshold = 600.66  

And finally, make the decision to dehydrate or not:

Dehydrate = (90 == -1 OR 90 > 600 OR 60 > (2 * 600))  
Dehydrate = false  

Using this example, you can determine that the orchestration will not be dehydrated at this time.
