Designing your CICSPlex SM environment

Map out your enterprise to design a CICSPlex® SM environment that meets your system management requirements. Your design must include topology information, such as identifying the CICSplexes, CMASs, and WUI server regions that are required, as well as making other design decisions such as what naming convention to follow.

Before you begin

To design a CICSPlex SM environment, you must be familiar with the concepts and components of CICSPlex SM.

About this task

You are given guidance on each step of the process of creating a design. An example also illustrates the process.

Procedure

  1. Decide how to group your CICS regions into system groups to identify what CICSplexes are required. The CICSplex is the largest unit that you can manage in your CICSPlex SM configuration.
  2. Decide how many CMASs are required for each CICSplex and how to link them together. The CMAS is the component of the CICSPlex SM topology that is responsible for most of the work involved in managing and reporting on CICS regions and their resources. Each CICSplex must have at least one CMAS.
  3. Decide how many WUI servers are required and how to link them to the correct CMAS.
  4. Decide on a naming convention for the CICSPlex SM components. The naming convention must be meaningful and extendable.
  5. Decide on an implementation strategy.

Results

Following these steps results in a detailed topology map of your enterprise.

What to do next

When you have completed your map of the enterprise, you are ready to plan the installation of CICSPlex SM to create your proposed configuration. Make sure that you keep your map up-to-date as you add more system groups or regions or make changes to the topology, because an accurate map makes it easier to maintain the CICSPlex SM configuration and topology data.

Subtopics

  1. Designing your CICSplexes
    The CICSplex is the largest unit that you can manipulate in your CICSPlex SM configuration. A CICSplex is made up of an association of CICS systems and CICS system groups. This section gives guidance on deciding how to group your CICS systems into system groups, and then to identify CICSplexes.
  2. Locating CMASs
    The CMAS is the component of the CICSPlex SM topology that is responsible for most of the work involved in managing and reporting on systems and their resources.
  3. Planning the location of WUI servers
    The location and number of WUI server regions in your enterprise depend on your availability requirements and national language support.
  4. Naming your CICSPlex SM entities
    All the entities that you have defined, and entered on to your CICSPlex SM map, have to be named. You must devise a convention for naming those entities that is both meaningful and extendable.
  5. A staged implementation
    If you have a very large number of CICS systems, or if you have decided to create multiple CICSplexes, you might want to consider implementing CICSPlex SM in stages.
