I have not heard of server crashing due to PCI slot speed mismatch.
The higher speed PCI should step down to a lower speed automatically upon detecting a lower speed device.

maybe your filesystem is badly fragmented.

Use this command to check the number of avail inodes
df -o i

use ptree in Solaris & Linux

sorry for my denseness, what do you mean by, "monitoring thread rather than a monitoring process" ?

tks for the info. I have a multi-threaded socket program that handles incoming connection from 100 clients. Each thread handles 1 connection and 1 client's request typically take < 5 seconds for a...

log a case with SUN

Any reason why?

Any idea how to kill threads (not processes) in solaris?
I had checked the man pages for both kill and pkill to no avail.

Before you even try to use ndd to modify system parameter, I think you should use netstat -i 3 while you ftp a file of at least 200MB.

Look at the error column. If there is collision and dropped...

I beg to differ. Normally, a wrong entry in the semaphore in the /etc/system file will cause the DB to be unable to start up.

If the error you see happens a couple of days after restarting the DB,...

Does blocksize matter in tar?
Why do you wanna use the non-default?

log a call with SUN support

I think you can go to /boot dir and edit some files there.
Think the file is something like bootenv.

use vmstat and look at the column under sr.
If it is ZERO, you have enough memory on the server

If you are using Solaris 10, you can use the iosnoop command that is built with DTrace. Search google for the iosnoop script.
It is able to break down the IO per binary.

could it be that your local filesystem/ drive is full, which is why you can create inodes BUT UNABLE to write the data into the inode/file?

Assuming you are using a unix account named, coocoo to run your job.

- login as coocoo user
- vi $HOME/.forward
- Add in your email address in the .forward

To verify, send mail to coocoo user...

vi $HOME/.forward file as root user.
Add in your email address in the .forward file

You will get the bounced mail

prtconf | grep -i mem

swap -s

put the entry mailhost in the /etc/hosts
E.g.

a.b.c.d server_name mailhost


kill -HUP the sendmail daemon

Hi all,
I am trying to set a standard in my company for using sftp.
After search the web for differences btw rsa and dsa encryption algo, I couldn't really find any best practices for using sftp.

See my reply inline:

If my application is not stressing the CPU , why it consumes 50 % in prstat.
>> Even if it is 100% CPU util, it doesn't mean that you don't have enough CPU resources. You run...

To understand all those commands, go and read Adrian Cockroft book, SUN Performance and Tuning.

I can tell you these facts:
1) You have enough CPUs resources. No processes are waiting for your...

Looks weird that it is eating 50% of CPU time consistently.

Can you do a mpstat 3 10?
I think the application is not utilizing ALL the CPUS efficiently.

I dun think it is the server's problem if it is intermittent.

Can you try to do a traceroute from the 2 different source server to the same server?

My guess is there is something wrong with...
