tusc command

Shivkumar — Sat, 08 Apr 2006 12:37:30 GMT

Hi,

I want to examine java process of weblogic server on hpux.

Just wanted to know how to use "tusc" command to figure out if there is an issue ?

If someone has real time example, it would be appreciated.

Thanks,
Shiv

Hi Shiv,

First of all, Install "tusc" in your system,
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/tusc-7.8/

Next, How to use "tusc" with Java

Here is a good article from HP's DSPP

Shalom Shiv,

if the process is already running:

Get the process id and assign it to the variable proc

proc=$(ps -ef | grep | awk '{print $2}')
tusc -o $1 -p $proc &

All you need to make it work is to come up with a unique pattern for the weblogic daemon. You actually have enough admin experience that you should be able to id the process without my extra code.

This will hang a tusc collector on an already running process.

You can use tusc to start the process as well.

tusc -vfp -o /tmp/trace.log

Good Luck,

Happy to assist further,

SEP

Hi,

I tried to use "tusc" for Apache but got the output as shown below:-

[sksonkar@bigguy:/usr/local/bin]$proc=$(ps -ef | grep apache| awk '{print $2}')

[sksonkar@bigguy:/usr/local/bin]$ echo $proc
22025 22023 22024 22022 28054

[sksonkar@bigguy:/usr/local/bin]$ ./tusc -o $1 -p $proc &
[1] 28332
[sksonkar@bigguy:/usr/local/bin]$ tusc: getproc(28054): No such process
tusc: ttrace(TT_PROC_ATTACH, 22025, 0, 0, dad0001, 0): Permission denied

tusc: no process to attach to
^C
[1] + Done(1) ./tusc -o $1 -p $proc &
[sksonkar@bigguy:/usr/local/bin]$

Can someone suggest what these errors are ?

Thanks,
Shiv

Hi Shiv,

Try running "tusc" as root user. You were running from sksonkar. That is the reason for getting "Permission denied"

I executed the $tusc command as a root user.
We use power broker to gain privileged access.
