List,
We have a K580 running HPUX 10.20 and two Oracle 7.3.4 SIDs. When
the second SID is started it appears to hang the entire system. Until the
second SID is up the first is completely frozen (user sessions), glance
will not start or update if already running, etc. The load average climbs
to over 12 while the DB is starting and drops once it's up. Top will run
and shows the CPU very low which would indicate that the high load value
is due to IO. Sar shows disk queues pretty low though (=< .50). I can
log in a new session with no problem. The behavior of the system is
similar to when a disk dies and IO's get hung causing any IO related
process to hang. But, I can't find what kind of IO is hanging or why. We
have other similar systems which don't appear to have this problem. Has
anyone seen this kind of behavior before or have any suggestions as to how
to identify the bottleneck?
I will summarize.
Thanks.
