When you have identified your CICSplexes and MASs, you need to create the definition objects that will identify them to CICSPlex® SM. You should be aware that you will not have all the information required at this point; more information will emerge as the design of your CICSPlex SM system proceeds.
More information about designing CICSplexes is given in Designing your CICSplexes
Each CICSplex must be defined to CICSPlex SM by a name that is unique within the enterprise. Naming conventions are given in Naming your CICSPlex SM entities. You also should be aware that you will need other information for the CICSplex definition, which will become available as you proceed with the design of your CICSPlex SM system. This information includes:
A CICSplex is identified to CICSPlex SM via the CPLEXDEF view, which is described in CICSPlex System Manager Administration.
To enter this information, you can use the appropriate CMAS Configuration Administration (ADMCONFG) views, or the batched repository-update facility.
When you have created a CICSplex definition, you can associate CICS systems (MASs) and CICS system groups with the CICSplex. See Preparing CICS system definitions.
In order to be managed by CICSPlex SM, a CICS system must be associated with a CICSplex that is defined to CICSPlex SM. The definition establishing this association also contains information about how the CICS system is to use the BAS, WLM, RTA, and monitoring components of CICSPlex SM.
To create CICS system definitions, and to display information about CICS systems defined to a CICSplex, you use the CICSSYS view.
For every CICS system that is to be managed by CICSPlex SM, you must gather the following information:
This is sufficient data for adding the MAS definition to the CICSPlex SM data repository. If you know that you have special BAS, WLM, RTA, or monitoring requirements for any CICS system, you can enter those at the same time. Alternatively, you can update the CICS system definition later as new requirements become apparent. For example, you might want to collect some of the following information, which is optional and can be supplied after the CICS system is defined to CICSPlex SM:
To enter this information, you can use the Topology Administration (ADMTOPOL) views, or the batched repository-update facility. Note that the ADMTOPOL views are also used to create time-period definitions.
For each CICS system group to be defined to CICSPlex SM, you need provide only a name for the group, which may be unique within the CICSplex. The CICS system group must be defined before you can add CICS systems to it. To define a CICS system group, you use the ADMTOPOL views.
Defining CICS system groups, perhaps more than any other part of the design stage, is an iterative process and a cumulative one. It might be obvious to you already that there are natural groupings of CICS systems within your CICSplexes, and that you will want to manipulate each of those groups as a single entity. If this is the case, start to document the groups now. Because groups do not have to be mutually exclusive, and because a CICS system can belong to any number of groups, you can add CICS system group definitions as new requirements emerge.
To create CICS system groups, you use the CICSGRP view.
You can display information about the CICS system groups, and the CICS systems associated with them, that are known to the CICSplex identified as the current context, by using the SYSGRPC view.
For a CICS system to communicate with another CICS system, the connection between the two systems may be specified by a link definition. A link definition is used to automatically create the matching CICS resource definitions (connection and session definitions) required in the two connected CICS systems. These link definitions are used by CICS (not CICSPlex SM); for example, for transaction routing between CICS systems.
To create CICS system link definitions, and to display information about those definitions, you use the SYSLINK view.
CICS system definitions are managed through the following objects:
CICSPlex SM provides the MAS view that you can use to manage configuration definitions when the associated CICS systems are active.
This view is described in CICSPlex System Manager Administration.
