Each maintenance object specified for a DB process represents a DB process instruction. DB processes instructions used for archive and purge are the metadata that background processes use to build the subset of production data eligible for archive or purge (see archive root objects). DB process instructions specify exclusion criteria or extra processing that is done when an archive or purge procedure is performed.
