Expired files are not deleted from server storage until expiration
processing occurs. You can invoke expiration processing in a number of
ways:
The expiration interval server option can specify that processing be
invoked at a set interval from the time the server is started. The
default is a 24 hour interval.
You can issue the EXPIRE INVENTORY command manually whenever you wish (see
the following example).
You can schedule the EXPIRE INVENTORY command to be issued regularly at a
specific time (see Automating Administrative Commands). If you schedule expiration processing, set the
expiration interval server option to 0.
