Biztalk Explorer OM not Supported in a 64 bit Environment

Imagine a scenario where you want to create 1400 receive locations; to make life simpler, you’d probably want to use WMI or the BizTalk Explorer OM.

Not much of an issue there, however what happens when you try an run some custom C# code that creates the receive locations (and therefore references the Microsoft.BizTalk.ExplorerOM assembly) from within an orchestration [expression shape] that executes as a 64-bit process?

You get the following error XLANG/S error:

Event Type: Error
Event Source: XLANG/s
Event Category: None
Event ID: 10034
Date: 14/08/2007
Time: 19:22:49
User: N/A
Computer: WINBT01
Description:
Uncaught exception (see the ‘inner exception’ below) has suspended an instance of service ‘Demo.Integration.CustomerLink.Orchestrations.UserAdministration(108ace24-3b9d-e084-c9ea-f342878676e6)’.
The service instance will remain suspended until administratively resumed or terminated.
If resumed the instance will continue from its last persisted state and may re-throw the same unexpected exception.

Shape name: CreateFileReceiveLocationExpression

Exception thrown from: segment 1, progress 22
Inner exception: Explorer OM is not supported in a 64bit process.

Exception type: BtsException
Source: Microsoft.BizTalk.ExplorerOM
Target Site: Void .ctor()
The following is a stack trace that identifies the location where the exception occured

at Microsoft.BizTalk.ExplorerOM.BtsCatalogExplorer..ctor()
at Demo.Integration.CustomerLink.FileReceiveLocation.Create(String user)
at Demo.Integration.CustomerLink.Orchestrations.UserAdministration.segment1(StopConditions stopOn)
at Microsoft.XLANGs.Core.SegmentScheduler.RunASegment(Segment s, StopConditions stopCond, Exception& exp)

Hmmm, that’s a bit odd, especially given that both the custom and Explorer OM assemblies are compiled to MSIL (not a target platform), which should suggest that when invoked from the 64-bit orchestration the JIT-Compiler will compile both to run a 64-bit process:

Explorer OM Assembly configurationThis doesn’t appear to be the case at all – in order to successfully run, you need to force the Host under which the orchestration is executing to run in a 32-bit process (rather than the native 64-bit) using the ’32-bit only’ checkbox on the Host Properties page:

Host Properties PageThis doesn’t make much sense to me, so I plan on doing more investigation into the problem. I’ll post my findings once I have a definitive answer.

  1. Hey Nick,
    We have run into the same situation when deploying an app to a 64-bit environment. Did you have any luck getting around this? So far it does not look like setting the “32-bit only” flag is trivial, since we already have a host instance, and also we would not be leveraging the 64-bit platform.

    Did you find an good replacements for ExplorerOM functionality for a 64-bit system?

    Allen

  2. I am curious what the work around is on 64 bit environment if we are using the ExplorerOM. I need to be able to stop and start BizTalk applications programatically and the Sample App – ApplicationManager – that is provided in the Samples of the BizTalk 2006 R2 SDK does not work on 64 bit environment. Changing the Application to run under a 32 bit host is not an option.

  3. Matt,
    I agree that changing the Application to run under a 32 bit host is a pain and not something that should really be done – I no longer have a 64-bit environment on which to test, but I would be interested to see whether WMI has the same problems?

    Alternatively, Microsoft are now accepting bug reports through its Connect website – I think this should be raised as a bug as its unacceptable in my opinion.

    Nick.

  4. Hello guys,

    Any work around for this issue? Please send me if you have any solution.

    Thanks in advance.
