Overview

Many enterprise applications span mainframe and distributed (Linux/UNIX/Windows) environments. Sometimes the level of mainframe involvement is light (for example, only for backend database solutions), while at other times the mainframe can host more than the distributed side (for example, running through queues, middle-tier applications, and multiple mainframe subsystems).

The goal of Data Flow Management (DFM) is to properly map applications across the infrastructure, regardless of where those applications reside. There are normally three parts to mapping an application across the infrastructure:

  1. Discovering the infrastructure

  2. Discovering the application

  3. Mapping the application dependencies

The current discovery solution covers the first two parts on the mainframe by discovering z/OS host and network resources, as well as applications such as DB2, IMS, CICS, and MQ.

The Mainframe by EView discovery is an agent-based discovery solution. It uses an application called EView/390z Discovery for z/OS to discover the Mainframe topology.
