COM+ events may be raised incorrectly when you have multiple Library COM+ applications that are loaded in a single process (918328)


The information in this article applies to:

  • Microsoft COM+

SYMPTOMS

Microsoft COM+ events may be raised incorrectly when the following conditions are true:
  • You have multiple Library COM+ applications that are loaded in a single process.
  • More than one of the COM+ applications is configured for transient events.
COM+ events may be raised on all the listed Library COM+ applications. Alternatively, no COM+ events may by raised.

This behavior occurs only for Library applications in COM+. You can have multiple Server applications that are subscribed to COM+ events.

CAUSE

This behavior occurs because of a limitation in COM+.

WORKAROUND

To work around this behavior, configure the COM+ applications as Server applications instead of as Library applications. When you configure the COM+ applications as Server applications, each application is hosted in a different process.

To configure the COM+ applications as Server applications, follow these steps:
  1. Open Component Services.
  2. Expand Component Services, expand Computers, expand My Computer, and then click COM+ Applications.
  3. Right-click the COM+ application that you want to modify, and then click Properties.
  4. Click the Activation tab, select the Server application option, and then click OK.

STATUS

This behavior is by design.
