I am running ADSM 3.1.22 on OS/390 2.6.  I have a client backup schedule
that begins at 20:00 and is set to last 8 hours.  I am finding that many
clients are not being backed up each night and a message is being
written to the log stating: "ANR2578I Schedule BACKUP21 in domain
DOMAINNAME for node NODENAME has missed its scheduled start up window."
Last night I watched a machine check in after midnight but before the
schedule finished.  When it checked in, it established a session and
then generated the error "ANS1815E Either the window has elapsed or the
schedule has been deleted"

Am I therefore to conclude that a backup schedule can not cross
midnight?

Thanks,
Ryan Carter
