HP-UX parameters may need to be changed before you run the HAFM client
The following two HP-UX 11.0 kernel parameters are set too low for most
Java applications. Usually you will see this problem as a java.lang.OutOf
MemoryError:
the issue, edit the following parameter limits:
max_thread_proc—The maximum number of threads allowed in each
process. The minimum value (and default) is 64, which is often too low for
most Java applications. Set the value of the max_thread_proc higher than
the expected maximum number of simultaneously active threads. The maximum
value is the value of nkthread.
nkthread—The total number of kernel threads available in the system. This
parameter is similar to the nproc tunable except that it defines the limit for
the total number of kernel threads able to run simultaneously in the system.
The value must be greater than nproc. The default is approximately twice that
of nproc. The maximum is 30000. The suggested value of nkthread is
2*max_thread_proc. If you have many Java processes running and each
running process uses many threads, you should increase this value.
Ethernet port on HAFM appliance may encounter problems
When you use TightVNC to access the HAFM appliance and you are running HAFM
locally on the HAFM appliance, the Ethernet port on the HAFM appliance can appear
to hang. When the Ethernet port encounters problems, the following may occur:
There is an apparent loss of communication to switches being managed by
HAFM.
The appliance CPU usage and memory usage display abnormally high readings.
Workaround
If this condition persists, it may be necessary to reboot the HAFM appliance. This is not
disruptive to managed switches, but monitoring and logging functions are interrupted
while the appliance is rebooting.
