Administration objects

These are the objects you use to relate resource definitions to each other and to CICS® systems.

Base objects
These objects are the foundation of BAS. They implement the assignment and installation of resources in CICS systems.
RASGNDEF
A resource assignment describes selected resource definitions of a given type and indicates how those resources are to be assigned to various CICS systems.
RESDESC
A resource description identifies sets of logically related resource definitions. The set of resources identified in a resource description can be used as the scope value for CICSPlex® SM requests. The resources can also be installed as a set in CICS systems that support resource installation.
RESGROUP
A resource group is a set of related resource definitions. The resource definitions in a group can be of the same or different resource types.
Association objects
These objects control the relationships between the base administration objects and their resource definitions.
RASINDSC
Associates a resource assignment with a resource description.
RESINDSC
Associates a resource group with a resource description.

The following figures provide an overview of the end-user interface views used to create these administration objects and associations. Figure 1 represents a simple (or interim) approach to managing CICS resources using the CICSPlex SM object model of definitions in groups, groups associated with descriptions, and descriptions associated with CICS systems.

Start of changeFigure 1. Views for managing CICS resources - a simple approach
 The diagram illustrates the relationships between some of the views used for managing CICS resources. EUI view names are in brackets. The following views are described beginning at the top with CICS system definition (CICSSYS), which defines CICS regions to CICSPlex System Manager, specifies whether resources defined in Resource description definitions (RESDESC)sR are to be autoinstalled and specifies recovery procedures. System group definition (CICSGRP) identifies groups in a CICSplex. Resource description definition (RESDESC) identifies sets of logically related CICS definitions that can act as a scope and which are allowed to be autoinstalled when a MAS connects to a CICSplex. Resource group in resource description (RESINDSC) associates resource groups with resource descriptions. Resource group definition (RESGROUP) defines a set of related resource definitions. CICS resource definitions in group (RESINGRP) associates a resource definition with a resource group. The  resource Definition (resDEF), for example Connection definition (CONNDEF) describe the attributes of a particular resource.

Figure 2 illustrates a more selective approach with the resource assignment playing a key role in the selection and assignment of resources.

The following views are described beginning at the top with CICS system definition (CICSSYS), which defines CICS regions to CICSPlex System Manager, specifies whether resources defined in Resource description definitions (RESDESC)s are to be autoinstalled and specifies recovery procedures. System group definition (CICSGRP) identifies groups in a CICSplex. Resource assignment definition (RASGNDEF) identifies which resource definitions are selected and which CICS systems they are assigned to. Resource group in resource description (RASINDSC) associates a resource assignment with a resource description. Resource description definition (RESDESC) identifies sets of logically related CICS definitions that can act as a scope and which are allowed to be autoinstalled when a MAS connects to a CICSplex.

There are two additional types of Business Application Services administration objects:

Process display objects
These objects illustrate how resources will be assigned to CICS systems.
RASPROC
Identifies the resource definitions to be selected when a given resource assignment is processed.
RDSCPROC
Identifies the resource definitions to be selected when a given resource description is processed.
SYSRES
Identifies the resources that are defined to a specified CICS system.
Connectivity objects
These objects describe the nature of communication links between CICS systems.
CICSSYS
Describes the operational characteristics of a CICS system, including resource installation options and the system ID to be used in identifying system links. You can use CICSSYS to create system links to other CICS systems. See CICSPlex System Manager Administration.
SYSLINK
Describes the links that exist between CICS systems in your CICSplex. You can use SYSLINK to create and install CICS system links.
