How to Modify Orchestration Memory Throttling Settings

The BizTalk Server host instance memory throttling mechanism continuously monitors for a throttling condition, calculates the severity of the throttling condition, and applies host instance memory throttling progressively depending on the calculated severity. This topic provides the step-by-step procedure to modify these settings using the Settings Dashboard.

Prerequisites

To perform this operation, you must be logged on as a member of the BizTalk Server Administrators group.

To modify the orchestration memory throttling settings of a host instance

1. In the BizTalk Server Administration Console, expand BizTalk Server Administration, right-click BizTalk Group, and then click Settings.

2. In the BizTalk Settings Dashboard dialog box, on the Host Instances page, click the Orchestration Memory Throttling tab.

3. Do the following, and then click Apply to apply the modifications and proceed to another tab. Or click OK to apply the modifications and exit the Settings Dashboard.

   Host Instance	From the drop-down box, select the running instance of a host on the BizTalk Server runtime machine.	-	-

   Physical

   Use this	To do this	Boundary values	Default value
   Optimal usage	Specify the percentage of physical memory usage at which dehydration throttling comes into effect. This is the optimum percentage of physical memory to use for the host instances.	[0 – 100]	70
   Maximal usage	Specify the percentage of physical memory usage at which dehydration throttling is maximum. This is the maximum percentage of physical memory to use for the host instances. The minimum value of Maximal usage should be Optimal usage.	(Optimal usage – 100] Except when both are 0 or 100.	85

   Virtual

   Use this	To do this	Boundary values	Default value
   Optimal usage	Specify the percentage of virtual memory usage at which dehydration throttling comes into effect. At this point, TestThreshold has the value MaxThreshold and any memory usage greater than OptimalUsage causes TestThreshold to be less than MaxThreshold.	[0 – 100]	65
   Maximal usage	Specify the percentage of virtual memory usage at which dehydration throttling is maximum. At this point, TestThreshold has the value MinThreshold and any memory usage less than MaximalUsage causes TestThreshold to be greater than MinThreshold.	(Optimal usage – 100] Except when both are 0 or 100.	85

   Note

   To restore the default settings, click Restore Defaults.
