catalina_pid file contains +1 pid number instead of correct pid
Hello Everybody
We are using Tomcat 6.20 in CentOS 5.3 server.
I have recently enabled catalina_pid functionality using environment
variable.
The PID file got created and contains +1 PID number.
If the Tomcat's real PID number 5446, the pid file would contain 5447 as PID
number.
Please help me to resolve this problem as we are using tomcat in 10 of our
servers.

If upgrading tomcat in our setup is that easy, i wouldn't have asked for help
here.
We are running tomcat in production server with large customer base.
We don't want to do radical changes to fix one problem.

If you had just posted both of them, you might have an answer by now.

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

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?

Posted by Cooper man <mi...@spika.com>.
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

Re: catalina_pid file contains +1 pid number instead of correct pid
Posted by Raghu GS <ra...@i10n.com>.
Thanks for showing your interest in helping me resolve the issue.
Do you want me to post bash/shell output or catalina.out file's output?

So, when you look at the PID file you get, say "1235" but when you run
a "ps" you see your JVM process is PID "1234"?
I'm surprised that's the case. I would buy that the pid of the
/script/ was "1234" and that the JVM is "1235" but I guess strange
things can sometimes happen.

We're not entirely sure of the problem, so coming up with a solution
isn't going to be terribly easy.
Can you show us what happens when you do this:
$ bin/shutdown.sh
$ bin/startup.sh
$ cat "$CATALINA_PID"
$ ps aux | grep 'java\PID'

Actually the PID number in the PID file is not wildly incorrect.
So, please suggest me an easy to implement solution.

6.0.20 ??
You should read
http://tomcat.apache.org/security-6.html
as well as all the fixed issues in changelog.

catalina.sh is a shell script file. There are not many secrets there
and it is editable.
You should try to debug what really goes on on your system.
IIRC there were some talks about using "exec" command vs "eval"
command in the script to launch the process.
Anyway, if CATALINA_PID file were not working I think somebody would
report it, but 6.0.20 was so old ago and I do not remember such
reports.
