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