Re: System Check in hang condition.
When the system "hangs" can you still log in? If you are already logged in, can you execute any commands?
If you can run commands, things like 'top' and 'sar' are useful to see what is happening.
'top' or 'glance' would be my first step to see what exactly is running and how much CPU it is using.

SolutionIn a Hanging time we have to check teh CPU and Memorey Utilization is high or not and check the is there any pageout is there or not.
Use the glance command to check the memory utilization,CPU utlization and cheked is there any pageout is there or not.
and then use the top command to identify, which process is taking much time.Here you can easily find out.
#/usr/bin/top
after that you grep that particular process.
use the below command.
# /usr/bin/ps -aef | grep oracle
above mentioned command will show sub process details of that Oracle process.
#/usr/sbin/swapinfo -atm

#/usr/sbin/vmstat
above mnetioned two commnds will show the memeory utilization is high or not.
to kill the process teh system will be coming to a normal position.

Re: System Check in hang condition.
There are lot of things to check when your system is in hang state.
1.Are you able to login when system was hang?
2.Did you check the syslog.log for any error?
3.Are you able to run any command?
4.Using top, sar and glance you can check which process are running.
5.Are you able to run ls or bdf command ?

Re: System Check in hang condition.
If the server is responding slow, it means it is running sort of some resources. You have to check the resource utilisation for cpu/memory/swap/disk i/o etc.
If you are not able to access during that period, take the system dump and analyse it to find what went wrong. You can ask HP help to analyse the dump files.
