This chapter describes patches, provides best practices, and includes step-by-step procedures for applying patches.
4.1 Managing Software with Patches
Software management involves installing or removing software products. Sun and its third-party independent software vendors (ISVs) deliver software as a collection of one or more packages. Patches are generally delivered as a set of sparse packages. Sparse packages are a minimalist version of a regular package. A sparse package delivers only the files being updated.
The following sections describe patches and provide step-by-step procedures for applying patches. Also, a best practices section provides planning information for proactive and reactive patching.
