Merge Modules

Merge modules provide you with a standard method by which you can deliver shared Windows Installer components and setup logic to your applications.

The Deployment Toolkit includes a merge module (.msm file) which you can merge into an application’s Windows installer package (.msi) file to make available all of the COBOL Server components. It also includes a merge module for the Microsoft Visual C++ Runtime, which is a prerequisite of COBOL Server.

The names of the supplied merge modules are different for 32-bit and 64-bit Windows systems.

For 32-bit Windows systems they are:

cobolserver_23x86.msm - the COBOL Server merge module
cobolserver_core_23x86.msm
cobolserver_net_23x86.msm
Microsoft_VC110_CRT_x86.msm

For 64-bit Windows systems they are:

cobolserver_23x64.msm
cobolserver_core_23x64.msm
cobolserver_net_23x64.msm
Microsoft_VC110_CRT_x64.msm

Depending on the type of applications you deliver, you need to include the following merge modules:

Native COBOL applications - you only need to ship the *_core_* merge module
.NET COBOL applications - you need to ship both the *_core_* and the *_net_* merge modules
JVM COBOL applications and applications that use the Consolidated Tracing Facility (CTF) - you need to ship the entire COBOL Server merge module

See MSDN for more information on merge modules.
