Processes X Archive...

Abel Berger — Mon, 14 May 2001 13:01:14 GMT

Hello all !

I have an archive where an application that I manage is generating logs. But he is difficult to identify the cause. Somebody knows if
some command in the HP-UX (10.20) exists
that says which processes to me is having access determined archive.

Thanks a lot !

Hi Abel,
I think you can find useful the lsof utiliy.
#lsof X
gives you the PID of the process that have X archive open.
You can find lsof in http://hpux.cs.utah.edu/

I try use the fuser command, but the aplication
is big and many process log in a log file.

I think that I will forget this !

Thanks Juan.

Hi Abel,

I think I understand you question and there are two tools which will do the trick.

1) fuser - man fuser to see how it works
and a much better option though you will need
to downloand a binary version from one of the HP-UX Porting Centers - it's called 'lsof' List Open Files

you simply lsof /usr
and it will list every process accessing /usr.

Hope I understood what you are asking, Clay

Hi Clay,

If I use the lsof software how is the output ? PID ? PPID ?
Because de fuser output is following :

# fuser /opt/sgt/logs/uproc.log

Clay,

How you can see the processes are many and
Is much difficult find what process are generating log in the uproc.log file.

I?m correct or not ?

Thanks a lot !
