Good morning everybody. I am not unix user or even UNIX administrator. I really need help from some UNIX experts here to solve problem on my server running open solaris. The machine is too slow, and behave sometimes weird. The only one that I can do is the command ps -ef on the shell. Here is the following output
I would really appreciate if someone of you can help me by analysing these processs output that cause the system act weird.
Thanks and regards

We'll start with the simple stuff and focus on CPU issues, there's also IO and memory to think about but that's very hard to diagnose over a medium such as this.
Try running the following commands:
Lists the most CPU intensive jobs running
Shows how long the system has been running for but also lists the 'load average' (number of jobs waiting on CPU to run at any given time - a number less than 1 means it's not waiting) in 5, 10 and 15 minute averages.
At a guess from your ps output though I'm thinking your 'plo' tasks will be the culprit.
df -h -- to show if any disk partition is overloaded
iostat -ne -- to show some hard or soft errors
prstat -Z -- to show which process is taking how much CPU utilization
metastat -- to show if any disk is in sync.
"sccli" followed by "show disks" to check if there is any faulty disk (asuming extrenal harddisk ex. SE3510 is attached to this solaris machine, or any thing equivalent for other type of machine which may check for the disk's status)
