"OpenVMS infrastructure" is the term that OpenVMS engineers use to describe the software plumbing above the kernel that supports COM for OpenVMS. The infrastructure supports more that just COM for OpenVMS in fact, it touches just about every OpenVMS subsystem but it's a convenient collective term to describe all the supporting players in the COM story.
A short history of COM on OpenVMS
Before I explain the how of COM for OpenVMS the technical details of the architecture and subsystems that support it I'd like to cover the why.
At first, you might think that COM for OpenVMS as just another layered software product. It's not. COM for OpenVMS is the result of years of planning, design, coding, and testing to make integration of Windows NT with OpenVMS transparent to users. COM for OpenVMS marks both the completion of the Affinity for OpenVMS Program and the start of making component technologies available on OpenVMS. The following sections explain the business needs, customer requirements, projects, and what we built along the way.
