Working with change packages
A change package can identify a set of resource definitions that you want to process together, or it can contain a set of commands that you want to process together, or both.
A change package can be used to add, remove, delete, install or back out resource definitions.
A change package does not contain resource definitions; it contains selection keys that
refer to resource definitions stored in a CSD file or a CICSPlex® SM context. A selection key identifies a resource definition by its name, group,
type, and CICS® configuration. For more information, search
for Change packages
in CICS Configuration Manager for z/OS product documentation.
