Sous-processus Arbortext PE Pool Parameters
In addition to the Sous-processus 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 Sous-processus Arbortext PE pool starts an Sous-processus Arbortext PE, it passes the Arbortext PE Request Manager global parameters and any Sous-processus Arbortext PE pool parameters and their values to the Sous-processus Arbortext PE, making them available to its Arbortext Publishing Engine applications.
