INF: Invoking COMTI Method Elicits MTS Event ID 4128

• Microsoft COM Transaction Integrator for CICS and IMS, versions 1.0, 4.0 SP2
• Microsoft SNA Server, version 4.0 SP2

SUMMARY

After successfully implementing a Microsoft COM Transaction Integrator for CICS and IMS (COMTI) application using SNA Server 4.0 Service Pack 1 (SP1), this release of SNA Server is uninstalled and SNA Server 4.0 Service Pack 2 (SP2) is installed.

Afterwards, COMTI methods fail with the following entry appearing in the application Event Log:

Event ID: 4128
Source: Transaction Server
Type: Error
Category: Class Factory Wrapper

The run-time environment was unable to load an application component due to either an error obtaining its properties from the catalog, loading the DLL or getting the procedure address of DllGetClassObject. This error caused the process to terminate.
C:\SNA\COMTI\Tagen.dll (Package: OneMoreTime) (Microsoft Transaction Server Internals Information: File: d:\viper\src\runtime\cfw\ccomdll.cpp, Line: 151)

MORE INFORMATION

The problem is related to the fact that SNA Server 4.0 SP2 is installed in a different directory, by default, than SNA Server 4.0 SP1, C:\Program Files\SNA, and C:\SNA, respectively. Those who use the defaults and have chosen to reinstall SNA Server instead of to upgrade SNA Server may incur this problem.

There are at least two workarounds:

• Install SNA Server 4.0 SP2 using the same directory structure that SNA Server 4.0 SP1 was installed in.



• Uninstall the COMTI application component libraries from their MTS packages, and then reinstall them.
