By manual striping, I think he meant the old practice of manually
pre-allocating extents to specific datafiles. I don't think anyone does
this anymore. Back in v7 Oracle used to allocate extents in a different
way than it does today. If you had multiple datafiles in a tablespace,
it would fill the first datafile, then the second, etc. Now it
distributes the extents evenly across all datafiles in the tablespace,
effectively doing automatically what DBA's used to have to do manually.
You can probably still find references to manual striping in the old v7
manuals if they are still online anywhere.
