System hanging !!
We have 2 oracle intance on our hp box. From last few days we have facing a problem of system going in hang status whenever the users connect to input data. The IDLE % becomes 0 as the users do transaction
We have rebooted the server.
Currently it is the same situation.
The cpu usage is as below:
System: server1 Fri Oct 17 08:52:07 2008
Load averages: 3.43, 3.00, 3.48

Re: System hanging !!
This are not very nice problems.
Seems that you are suffering from either
a genuine bottleneck or just a roque feature (bug) on either HPUX or Oracle
Check the logs of both OS and Oracle?
Version OS and Version Oracle,
is this problem know on Metalink ?
Are any patches due ?
Did you comply to kernel parameter prerequisites ?
What are the size of each SGA in relation to your unix memory
Can you identify a resident set that is growing ps -efl | grep oracle
look for column SZ
Does the problem occur also with one instance?
How many query are run on your system ?
Did you apply statspack and analyze where the bottleneck are ?

Re: System hanging !!
can you tell us a little more about the processes : I assume oracleuser1, mocasrvprc and/or oraclenuser1 are the Oracle user processes (dedicated connection), but which 2 out of these 3 are oracle, and what is the other one.
What version Oracle are you using ? With this information we can see what tools are available.
When is the database hanging up, just with whatever connection you make ? Or when users from a certain application start making connections.
What happens if you just kill the most busy user connections ? Does it allow you to continue working for a few seconds/minutes ?
Have you tried to run statspack or AWR reports ?
