Data set and sphere integrity
By default, IMS Cloning Tool detects and fails the rename process if one of these data set integrity rules is violated.
The following table lists the integrity rules for each type of data set.
| Data set | Integrity rule |
|---|---|
| Multivolume data sets | All segments of multivolume data sets, where the source volume data set matches a rename mask, must be wholly contained within the list of source volumes. The term “multivolume data sets” implies multivolume data sets, striped data sets, and VSAM spheres. |
| VSAM spheres | All components and associations of VSAM spheres, where the cluster name matches a rename mask, cannot be partially must be wholly on the source volumes. The volume list must include all components of a cluster and alternate indexes and index components that are associated with the base. |
| GDGs | All available generations of a GDG base, where the base name matches a rename mask, must be wholly on the source volumes. Exceptions are allowed for available generations that are on tape or are migrated to other media; however, IMS Cloning Tool references to such target entries fail. |
| Non-VSAM data set aliases | If a data set on a volume matches a rename mask and has one or more aliases, all aliases must also match a rename mask. |
