Defining resources

BAS enables you to define and maintain your resource definitions by providing a view for each resource type. See Table 3.

The definition of resources for CICSPlex® SM is similar to CICS® RDO. To define a resource, you create a resource definition object. You describe the attributes of the resource in the definition but you do not need to define every occurrence of every resource; you can use a small number of resource definitions as templates for the creation of large numbers of resource definitions. The resource definitions are stored in the data repository for the CICSplex.

The differences between CICSPlex SM resource definition objects and CICS resource definitions are:

You can create resource definitions in three ways:

Validating resources

BAS performs many of the same resource definitions checks as RDO does. As individual resources are defined and installed, BAS checks:

In addition, BAS checks that each set of resources is consistent. Every time you make a change to a resource set, BAS checks that the resource being added or updated is not in conflict with a resource already in the CICS system. For example, you would get an inconsistent set error if you tried to assign different versions of the same resource to the same CICS system, or assign a resource as both local and remote.

BAS also provides a MAP function that allows you to check that your resource associations are what you want. You use this facility to display the structure of your resource associations, starting at any point in hierarchy. Figure 16 shows an example of a resource definition map.

Defining resource groups

A resource group is a set of related resource definitions that you want to manage as a unit. Resources groups are defined using the RESGROUP object. The resource definitions in a group may be of the same type or of different types, but usually have something in common. They might be logically related by their use in a given application or communications network, or geographically related by their use at a given site.

There is no real limit to the number or combination of resource definitions that can make up a group. However, only one version of any given resource can be included in a resource group at one time. You have to maintain each version of a resource definition in a different resource group.
