Dead process

[O'lnes]

Our system suddenly run slowly, i think it is due to some dead processes in the system, but i can find it by 'top' function, can suggest how to find what process affect the speed of the system?
Thanks.

[Scott Van Kalken]

if it's a user process it will generally have a high amount of execution time.

If it's truly "dead" it will more than likely have a PPID of 1.

Some processes are supposed to have a PPID of 1, but some aren't.

hello,

Yes, there are couple of methods:
a) Run GlancePlus (gpm) if you have it loaded on the system, This is a performance analysis tool and will list you all processes running on the system and the resource usage
b) Run sar. Read the man pages for spefic informations.
c) if you have downloaded 'lsof' then run that against processes and find out any issues.
d) A full process list can be get from:
# ps -aef

gl,

Some dead processes will lost their process names in "ps -aef" and will show ""
in their names, these processes cannot be killed and a server reboot will clear all those defunct processes.

Hi,

#ps -ef | grep defunct

[O'lnes]

i can't find defunct process, where can get "glance" ? is it free?

Thanks.

[Kenneth_19]

A free trial version with limited trial period comes together with the software installation CD, it's called GlancePlus.

I have downloaded the program "glance", but can't run it even it is mode 777 , it shows "sh: ./glance: Execute permission denied." . Thanks.

Glance is a depot software
It is found on one of the application cds.
you have to use swinstall to install it.

Thanks

[O'lnes]

When intall 'glance', it pop up the message "
An I/O error occurred while performing this task" . how to solve ? Thanks.

[Kenneth_19]

Can you please supply the command that you used to install Glance?

Kenneth

[O'lnes]

'swinstall' then select local directory, and type in the path.

[T G Manikandan]

If it is a I/O error check the download size of the file whether the download was complete.

If you had transfered the download file from windows to Hpux.re-ftp the file from windows using the binary mode.

Thanks

[O'lnes]

I tried to install the file in the cd - "Glance/GLANCE/opt/perf/bin/glance" , but the same error occur. Thanks.

[T G Manikandan]

I think probably you are missing something.

you have Glance and GlanceplusPak in your application CDs.

Glance is the performance monitoring product.
To my knowing
GlancePlusPak product includes the Measureware/Perfview/Glance

You can install any of the two.


you can mount the application cd which contains the Glance.

do a swinstall

From the GUI screen window of swinstall select,
Local CDROM,
then select Glance
then
Actions---->Mark for install
then
Actions---->install analysis

which will install the product.
I am sure whether you are following the steps.

Please post back

Thanks

I copied the file "Glance/GLANCE/opt/perf/bin/glance" to local drive and run the swinstall, then it pop up the error "There is currently no depot software on host "xxx" at location /temp/", do i copy the right file? Thanks.

[Kenneth_19 · Accepted solution]

To copy a software depot, instead of using cp, you need to use swcopy.

Hi Kenneth,
1. even i directly install from CD-ROM , it still pop up the I/O error.

2. When i use swcopy to copy from CD-ROM to local drive , it pop up "
swcopy ./GLANCE/opt/perf/bin/glance

======= 08/05/02 21:26:04 EAT BEGIN swcopy SESSION (non-interactive)

* Session started for user "root@xxx".

* Beginning Selection
* Target connection succeeded for "xxx:/var/spool/sw".
ERROR: "xxx:/var/spool/sw": This target or source is already in use
either within this same session or by another session. A read

* Source connection failed for "xxx:/var/spool/sw".
WARNING: More information may be found in the daemon logfile on this
target (default location is gpe:/var/adm/sw/swagentd.log).

How to solve ? Thanks.

[T G Manikandan]

do a
ps -ef|grep sw
Stop or kill all other swcopy,swinstall sessions.
Then do a
restart of the swagentd daemon.
#/usr/sbin/swagentd -r

now retry the operation

Thanks

[O'lnes]

i have restart the daemon, and run swinstall again, it still have error.

[T G Manikandan]

Did you check ps -ef|grep sw
and stop or kill all swinstall,swcopy,swlist processes.

Then restart swagentd

If this is not working then

#mv /var/adm/sw/products/swlock /var/adm/sw/products/swlockold

#swagentd -r


Thanks

[O'lnes]

The same error when run swinstall again.

I have grep the sw process, but seems no error.

# ps -ef |grep sw
root 0 0 0 May 10 ? 439:48 swapper
root 1381 1 0 18:19:41 ? 0:00 swagentd -r
root 1404 29949 0 18:20:50 ttyr7 0:00 grep sw

[T G Manikandan]

#rm /var/adm/sw/products/swlock

#/usr/sbin/swagentd -r

Thanks

[O'lnes]

The same error when run the swcopy.
