A change package is a set of resource definitions or commands that are processed together.
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.See Change packages in the CICS® CM for z/OS® User's Guide
The CM plug-in contains a new view to manage change packages. The view is included in the default perspective or it can be opened from the menu by clicking on Window > Show View > Other.
To work with one of the change packages, double click the name. The change package editor opens.
You can scope the resources by selecting a migration scheme from the drop down. The file definitions and resource descriptions can be seen by expanding the twisties in the main list. Any errors are shown just above the resource list. These errors are written in plain text. The reason code is also given so that it can be used when reporting problems to IBM Support or searching for known problems in the IBM Support Portal.
