How to set up an trace log on HP-UX ?

[Thierry Doppler]

Hi,

I want to set up a trace to log all the processes running on my rx2620/HP-UX 11.23, to find a database sporadic error-job.

Is in HP-UX a tool available to to that ?

Thank you

Thierry

Hi Thierry,

Download and install tusc/truss from the link below.

Best regards,

I'm understandig that i have to give a process-id to look what this proces is doing. But I want to log something as the top-command, every second, in a file.

Hi,

If you use tusc with your process, you will get to know all the system calls it makes, return values, it is similar to "truss" on solaris. You can get detailed output when you use it with your erring process.

You can log all process with ps command as,

#!/bin/ksh
# process.ksh
LOGFILE=/tmp/process.log

while [[ 1 ]]
do

ps -ef >> ${LOGFILE}

# sleep time
sleep 60

done

# END
exit 0

Note: If you did not change sleep time then it will load more contents in log file. File will be added more and more. So keep sleep time more.

Using top utility then,

#!/bin/ksh
# process.ksh
LOGFILE=/tmp/top.log

while [[ 1 ]]
do

top -d 1 >> ${LOGFILE}

# sleep time
sleep 60

done

# END
exit 0

##############################

Note: top will not all process informations. You have to use ps command only to get all informations.

Thierry,

Maybe this tool can help you to pinpoint the source of your problem.
