How to use tusc utility on hp-ux

How to use tusc utility on hp-ux

Hi gurus,
I installed tusc utility to trace the process as i am getting problem in my database and Oracle recommend to trace the process when my DB listener hangs.
Steps done by me:
--Downloaded the file "tusc-7.8-ia64-11.23.depot.gz"
-- unzip on windows.
-- send as binary to /var/spool/sw/tusc-7.8-ia64-11.23.depot
-- installed software from sam
-- i can view the software from swlist

I run tusc as
# ps -ef|grep PMON
root 17706 17577 0 10:59:21 pts/0 0:00 grep PMON
# tusc -afpo 17706
sh: tusc: not found.

Please help to solve the problem.

Thanks,
Syed MOin

Hi,

Its because the PATH variable is not set.

1. #find / -name tusc -print

==> to check the location of the binary.

2. Add this folder to the existing PATH variable in .profile.

3. Alternatively you can excute the tusc with FULL PATH.

Siva.

HELLO SYED,

add /usr/local/bin/tusc entry in your .profile file.
it will help succesful execution of tusc binary.

Re: How to use tusc utility on hp-ux

hi,

you should use /usr/local/bin/tusc

hence /usr/local/bin should be in the PATH

see: http://hpux.cs.utah.edu/hppd/cgi-bin/wwwtar?/hpux/Sysadmin/tusc-7.8/tusc-7.8-src-11.11.tar.gz+tusc-7.8/HPUX.Install+text

kind regards

Hi Syed,

Normally "bin" folder contains the binaries/executables for any product.

So pls add the ../bin folder to the PATH and it should work now.

Re: How to use tusc utility on hp-ux


To run with full path,

taking your example itself

1. # ps -ef|grep PMON
root 17706 17577 0 10:59:21 pts/0 0:00 grep PMON


2. instead of doing,

#tusc -afpo 17706

Please run,

#/usr/local/bin/tusc -afpo 17706

Hi,
Thanks for all , when i read .profile file it mention as

PATH=/usr/sbin:$PATH:/sbin:/home/root
where should i add in the path or just as /usr/local/bin/tusc

when i run as
# /usr/local/bin/tusc -afpo 20992

Re: How to use tusc utility on hp-ux

Shyalom Syed,

Set the Process ID to the process you want to monitor.

#ppid collected above
proc=$ppid
/usr/contrib/bin/tusc -o $1 -p $proc &


Basically you have two usual methodologies.

You can hang tusc on a process and redirect the output to a file or you can use tusc to start the process.

In the case of monitoring an Oracle Listener process, the methodology above should work because I'd surmise the listener is started at the same time as the database.

Re: How to use tusc utility on hp-ux

Hello experts,

let me explain u guys my exact problem
my Oracle listener is hanging and i want to trace by using tusc recommended by oracle to view the log
when i use as lsnrctl and want to check the status its hang
i dont know how to trace the process and which process id should db traced at the time when listener hangs
if any oracle DBA's got the same problem let me know pls
i am just getting the process id by
#ps -ef|grep PMON
#/usr/local/bin/tusc -za 22071
and it gives me error as
tusc: getproc(22071): No such process
tusc: process 22071 (""): No such process.
tusc: no process to attach to

no replies about mentioning /usr/local/bin/tusc in ".profile"

any recommendations will be highly appreciated and helpful for me

Thanks,

Re: How to use tusc utility on hp-ux

Syed,

You don't want to use tusc in .profile.

proc=$(ps -fu tnslisten | awk '{print $2}')

/usr/contrib/bin/tusc -o $1 -p $proc > /tmp/tsuc.log &

This will do it. Your output will be in a file which you can compress and upload to Oracle support.

Re: How to use tusc utility on hp-ux

change tnslisten to the actual name of your listener process.

The process name varies with Oracle version.

I tried with the name of listener but still it doesn't work may be there is a little bit mistake by me. can u let me know what exact steps to check tusc on listener. my listener name is default LISTENER with oracle ver10g(10.1.0.4.0)

Thanks once again
