text: **Optical platters**
  When you work with optical platters, check and adjust the values for the following parameters 
  in SYS1.PARMLIB(CBROAMxx): 
  
  (cid:2)**MOUNTWAITTIME**: Specifies the amount of time (in minutes) that can pass while a volume 
  waits to be mounted on an operator-accessible drive within an optical library. After this 
  time expires, message CBR4426D is issued to allow the operator to try again or to cancel 
  the volume mount request. This value can be any numeric value 1 - 9999. If the operator 
  retries the mount request, the value that is specified in the**MOUNTWAITTIME**parameter is 
  used for the retry. The default value of this parameter is 5 minutes. 
  
  (cid:2)**OPTICALDISPATCHERDELAY**: Specifies the number of seconds that the OAM optical 
  
  dispatcher delays the processing of certain requests to minimize the flipping of optical disk 
  cartridges in an automated optical storage library that expects that another read request 
  for the currently mounted optical disk volume will arrive within this delay interval. 
  
  The OAM optical dispatcher delays processing of a unit of work for a specific period, when 
  *all*of the following conditions are true:
