In addition to the Sottoprocesso Arbortext PE pool attributes, a pool may have parameters. Each pool parameter is defined by the Parameter element, which is a descendant of the SubprocessPoolContext element (which is a descendant of the SubprocessPool element) in e3config.xml.

When an Sottoprocesso Arbortext PE pool starts an Sottoprocesso Arbortext PE, it passes the Arbortext PE Request Manager global parameters and any Sottoprocesso Arbortext PE pool parameters and their values to the Sottoprocesso Arbortext PE, making them available to its Arbortext Publishing Engine applications.
