Flow Map Manual

1 Introduction
098935 Tandem Computers Incorporated 1–1
This manual documents the Tandem Flow Map product. Flow Map has two
components, Flow Map Host (FMH) and Flow Map PC (FMP). FMH filters, reduces
and formats performance data collected by the Tandem Performance Data Collector
and Measure products. FMP is a Windows workstation graphical user interface. It
creates a flow diagram showing how the processes, files and connections of an
application running on the Tandem system interact.
Uses for Flow Map Since Flow Map creates flow diagrams directly from data collected and reduced on the
host, it always gives an up-to-date representation of an application. Flow Map is a
valuable tool throughout an application's life cycle. The following lists show some of
the ways you can use Flow Map:
Documenting a Working
Version of Your Application
Flow Map supplements your application documentation development and helps you:
Find the actual flow of message traffic within an application.
Compare the actual flow to what was intended.
See the interaction of the application with other activities on the system.
Understand and optimize your Tandem Alliance “black box” applications to better
manage and optimize your system.
Quality Assurance (QA) of
All or Part of an Application
You can use Flow Map during QA to do the following:
Evaluate quality and help QA testers determine which areas need attention.
Assess usability to see if the product performs as documented.
Verify functionality to determine whether the product performs according to
design.
Manage Application
Change after
Implementation
Flow Map creates updated, always current documentation that is needed whenever an
application is modified to include enhancements or bug fixes. Flow Map will do the
following:
Document what the application is doing now.
Verify that new modules and code are performing as intended.
Manage Moving an
Application to a New
Environment
When moving an application to a new hardware or software environment, you can use
Flow Map to help you do the following:
Plan the move to the new environment. When you install new hardware, a new
operating system, value-added software, or interim product modifications (IPMs),
use Flow Map to understand and document how your application is functioning
and performing within the new environment.
Understand what the application is doing in the new environment when
migrating an application to a new environment or from one system platform to
another.
Optimize your application for the new environment.
