Orchestration Instances
|
|
|
| Hi All,
Is there any limit on the orchestrations instances at any
point of time in memory. How is it controlled in the
Biztalk. If I have an orchestration expecting a file, and
if I drop 1000 files, how many instances of orchestrations
are created at a time? What factor does it depend on?
When does an Orchestration instance die? How long does it
take?
Thanks,
-SP

| Thank you Matt. May be I was not clear, but What I wanted
to know about is Orchestration instances in memory at a
time.
I am working on a simple project using a file adapter and
orchestration. I dropped 16 files and started watching
PERFMON. I see 16 documents were received by Biztalk. But
only 12 Orchestration are created. Once some of those are
done, say 5-6, then rest of the orchestrations are
created. I would like to know the reason for this behavior
and what parameters cause this. The number of
orchestrations created at a time depends on the size of
file (guess).
Thanks,
-SP

| Read the Biztalk Performance Whitepaper found here.

It provides a detailed explanation of how process throttling and resource
contention are handled

| See the following code snipet to find out the number of running instances,
dehydrated instances, suspended instances.
ManagementObjectSearcher Searcher = new ManagementObjectSearcher();
// Create the scope node so we can set the WMI root node correctly.
ManagementScope Scope = new ManagementScope("root\\MicrosoftBizTalkServer");
Searcher.Scope = Scope;
SelectQuery Query = new SelectQuery();
Query.QueryString = "SELECT * FROM MSBTS_Orchestration WHERE Name = '" +
orchName + "'";
Searcher.Query = Query;
ManagementObjectCollection QueryCol = Searcher.Get();
foreach (ManagementObject mbo in QueryCol)
{
ManagementBaseObject inParams =
mbo.GetMethodParameters("QueryInstanceInfo");
ManagementBaseObject outParams =
mbo.InvokeMethod("QueryInstanceInfo",inParams,null);
int iRunningInstances =
System.Convert.ToInt32(outParams["NumberOfRunningActiveInstances"]);
int iDehydratedInstances =
System.Convert.ToInt32(outParams["NumberOfRunningDehydratedInstances"]);
int iSuspendedInstances =
System.Convert.ToInt32(outParams["NumberOfSuspendedInstances"]);
}

| Hi:
Look at this example.
http://geekswithblogs.net/sthomas/a...9/01/10508.aspx
It shows how to limit the number of Orchestration instances running in
memory.
