text: You control automatic expiration processing by using the expiration processing interval 
  (EXPINTERVAL) in the server options file (dsmserv.opt). You can set the option by editing the 
  dsmserv.opt file. For more information, see the*Content Manager OnDemand Installation and*
  *Configuration Guide*:

  If you use the server option to control when expiration processing occurs, ASM processes 
  expirations each time that you start the server. Afterward, it runs expiration processing at the 
  interval that you specified with the option, which is measured from the start time of the server. 
  
  You can manually start expiration processing by running the**EXPIRE INVENTORY**command. 
  Expiration processing then deletes information about expired files from the database. You can 
  schedule this command by running the**DEFINE SCHEDULE**command. If you schedule the 
  **EXPIRE INVENTORY**command, set the expiration interval to 0 (zero) in the server options so 
  that ASM does not run expiration processing when you start the server. You can control how 
  long the expiration process runs by using the**DURATION**parameter with the**EXPIRE INVENTORY**
  command.
