For More Information
Changes to this field may be of less consequence than changes to the analogous PermDBAllocUnit field because spool tables are not updated frequently. Nevertheless, care should be taken when considering a change to this setting. Before making changes to this field, refer to the information for PermDBAllocUnit.
