Supersession

Supersession is the process of replacing an earlier patch with a new patch. A new patch supersedes all previous patches for its particular patch chain. Upon installation of the new (superseding) patch, its files replace files of the patches being superseded. Patches for HP-UX products are always cumulative. Each new patch contains all aspects of all its preceding patches.

A series of patches form a supersession chain. A supersession chain includes the following:

•The nonpatch software product being patched.

•Each patch that fixes the nonpatch software product.

•Each patch that fixes the patches.

Figure 3-1shows a simple, hypothetical supersession chain in which a product has been superseded by PHXX_31937, which in turn has been superseded by PHXX_32384, which has been superseded by PHXX_43826. In general, patch numbers increase along a patch supersession chain.
