Server parameters
iXOS-JUKEMAN 2.2 User Manual Pre.12/97 125
It is often preferable to delay this disk exchange as data requests are
usually queued for the current disk. This parameter sets a limit according
the delay. Value 0 means a strict serial use of the access queue (not very
sensible). The greater the value the longer the delay even if there is not
access to the disk.
rahead=3
Specifies the number of chunks the data cache tries to read ahead.
reject=1
Specifies how incomplete disks are treated (e. g., if the burning process
for a CD was interrupted). For reject=0, iXOS-JUKEMAN tries to read
as much as it can from the incomplete disk. For reject=1, no incomplete
iXOS-JUKEMAN-CDs will be accepted. If set to 2, no incomplete disks at
all will be accepted.
The default is reject=1. If the disk is not fully readable, it is very likely
that some error occurred during burning the disk, and it appears as a bad
disk. This setting will make sure to mark only those disks as readable
where disk length and actually written data match.
trayto=60
This parameter can be used together with Kodak CDL 144, Hyundai HAS-
550, Plasmon D-Series, and Sony CDL-2*** jukeboxes. It is the time in
seconds that the server waits until the mail slot of a jukebox is closed
manually. After that time, the mail slot tray is closed automatically and the
new (or old) disk is tested.
For the Pioneer DRM 5004 X and the Grundig GMS 1035 the parameter
has a special meaning due to the virtual mail slot and the door hiding the
mail slot, respectively: It specifies the time-out for the user to open the
door, exchange the disk, and close the door again for a disk change. After
this time-out normal operation is resumed.
For all other types of jukeboxes this parameter is irrelevant.
