Organizing lists and groups or ResDescs and ResGroups
Lists and groups in CSD files are broadly similar in concept to ResDescs and ResGroups in CICSPlex® SM contexts: they offer two levels of hierarchy for organizing resource definitions. However, their implementations are quite different:
- In a CSD file, lists are independent from resource definitions. Each list refers to one or more groups. But groups do not exist independently from resource definitions. Instead, each resource definition in a CSD file refers to the name of a group; a group "exists" only because a resource definition refers to its name. A group can belong to more than one list, but a resource definition cannot belong to more than one group.
- In a context, ResDescs and ResGroups exist as independent objects. The relationship between a ResGroup and a ResDesc is defined by a separate object. Similarly, the relationship between a resource definition and a ResGroup is defined by a separate object. ResGroups can belong to more than one ResDesc, and resource definitions can belong to more than one ResGroup.
To create a list, group, ResDesc, or ResGroup:
- Expand the CICS® configuration to show the existing objects of that type. For details, see Exploring CICS configurations.
- Enter DEF on the command line to start with a blank object, or enter DEF next to an existing object to use it as a model.
