Chapter 5. Storage management 113
– No request exists for the currently mounted optical disk volume that is waiting to be 
processed on the OAM optical dispatcher queue.
– The OAM optical dispatcher found a read request for another optical disk volume 
(either the opposite side of the currently mounted volume or an unmounted optical disk 
volume) and is about to dispatch this unit of work.
– A nonzero optical dispatcher delay value is specified with the OPTICALDISPATCHERDELAY 
keyword on the SETOPT statement in the CBROAMxx PARMLIB member.
If another read request for the currently mounted optical disk volume arrives within the delay 
interval, that unit of work is dispatched immediately upon arrival. If no read request for the 
currently mounted optical disk volume arrives within the delay interval, another request for a 
different optical disk volume (either the opposite side of the currently mounted optical disk 
volume or an unmounted optical disk volume) is dispatched. Valid values for seconds are 
decimal numbers 1 - 60. If usage of this parameter is necessary, use of a low value, 1 - 5, is 
suggested.
ARS.CFG setting
If you are configuring a Content Manager OnDemand for z/OS system to use OAM for archive 
storage, you must ensure that the ars.cfg file is updated to reflect that OAM is used as the 
storage manager. Example 5-1 shows an example of the settings to configure for OAM 
archive storage enablement for Content Manager OnDemand.

5.3.3  Defining a storage set
When the Content Manager OnDemand administrator defines a new storage set, the Add a 
Storage Set window opens, as shown in Figure 5-12 on page 114.
