Re: catalina_pid file contains +1 pid number instead of correct pid
Hi Raghu,
My guess is that you have changed the logging to use cronolog and as such
the PID being written is actually the logging process and not the catalina
process. Check your catalina.sh file
If you see something like this
org.apache.catalina.startup.Bootstrap "$@" start 2>&1 |/usr/bin/cronolog
"$CATALINA_BASE"
Then there is your answer

Some *NIX's have a program called "pidof" which might be helpful. If
you run many processes with the same, it might not be so helpful.

Maybe you can get somewhere looking at the parent process ID (PPID)
column in ps output
and knowing the PID of cronolog process.

Re: catalina_pid file contains +1 pid number instead of correct pid
Posted by Cooper man <mi...@spika.com>.
No problem , glad I can be of help as it took me so long to figure it out too
You need to change the block where the pid is assigned which should be just
under the line I described
if [ ! -z "$CATALINA_PID" ]; then
fi
And this is a bit of a hack but something like this will give you the
correct pid.
Set application.name or soehting similar as a jave env variable and then
if [ ! -z "$CATALINA_PID" ]; then
ps aux | grep tomcat | grep application.name=YOUR_APP_NAME | head
-n 1 | awk '{ print $2 }' > $CATALINA_PID
fi

Hi Cooper Man
You are a genius.
you have perfectly guessed our setup and problem.
And I am very happy about finding the root cause finally.
Is there any solution for this problem?
