It would be nice to make the mainframes at our shop look more modern, sexy, and competitive compared to the Windows and Unix-based servers we’ve deployed. However, there are few opportunities for a techie to impress upper management by showing off the mainframe’s strengths. An exception is performance monitoring and management. Management is always concerned with how the mainframe is performing and how much capacity is being consumed. So why not use the best performance monitoring and reporting tools available to “knock their socks off ”?


Many mainframe systems programmers are perfectly content looking at raw Resource Measurement Facility (RMF) reports and character-based mainframe performance charts to monitor the performance and capacity of their mainframe(s). In the old days, management was comfortable looking at green screens containing character-based graphs. Today, they prefer sparkling, full-color graphs and charts, showing them, at a glance, the performance and capacity of their IT infrastructure components. Providing these is second nature for the Windows crew; that’s how they’ve always done it. With  the mainframe, we need to step up to the plate and use new tools to present our performance and capacity data in a form management desires. 

IBM’s RMF Performance Monitoring (RMF PM) Java Technology Edition is one of these new performance and capacity management reporting tools. RMF PM lets you monitor performance of your sysplex and z/OS hosts and produce performance charts and graphs using Java-based software you run on your Windows-based or Linux workstation. This article examines how to install and use RMF PM from a Windows workstation.

RMF PM Components and Installation

RMF PM is a client/server application. A server component runs on your z/OS host(s) and communicates with a client component that runs on your workstation. These two components communicate via TCP/IP. The server-side installation of RMF PM is simple and doesn’t require an IPL of your MVS image. The client-side implementation is also trivial.

Server Component Setup

The server component, Distributed Data Server (DDS), is a task you start that runs on your MVS image. DDS collects and forwards the data collected in RMF Monitor III and passes it to the client portion of RMF PM.

You must have these in place and operational on your MVS image for DDS to operate correctly:
