WebObjects/Web Applications/Deployment/Killing WOA Processes
This is one of the most vexing question. How to kill a run away WO application? The ps command does not give you any information as it list the process as java.
Try to use lsof. You need to run it with admin privileges so the command is
sudo lsof -i tcp:xxxx
Alternatively you can have a script:
#!/bin/sh # # portslay: kill the task listening on the specified TCP port # kill -9 `lsof -i tcp:$1 | grep LISTEN | awk '{ print $2;}'`
You will also have to do a sudo for the script to run.
For those stuck with the CLOSE_WAIT problems try this:
sudo lsof -i tcp:xxxx
Alternatively you can have a script:
#!/bin/sh # # portslay: kill the task listening on the specified TCP port # kill -9 `lsof -i tcp:$1 | grep CLOSE_WAIT | awk '{ print $2;}'`
run it by doing:
sudo ./portslay xxxx-yyyy
where xxxx is the first port and yyyy the last port
how about (pref. inside a script):
ps aux | grep java | grep <appName> | grep -v grep | awk '{ print"kill -9 "$2 }' | sh

[edit | edit source]I just use
ps auxww
which will show the full commandline. You can see the app name from this view.

[edit | edit source]On FreeBSD one needs to set
kern.ps_arg_cache_limit=1024
in /etc/sysctl to reveal the full command line with ps -auxww. To set it immediately:
sysctl kern.ps_arg_cache_limit=1024
Alternatively, one can use Johan's script below.

[edit | edit source]I have written a small script that uses lsof to find the process by looking at some specific file that is opened, the returned processes can then be used to kill the process
#!/bin/sh if [ $# = 0 ]; then echo "" echo " usage: $0 javaname(s)" echo " The current processes that containt javaname will be displayed" echo " eg: $0 JavaMonitor.woa" echo "" exit 1 fi OS=`uname -s` # echo $OS case ${OS} in 'FreeBSD') LSOF=/usr/local/sbin/lsof ;; 'Linux') LSOF=/usr/sbin/lsof ;; 'Darwin') LSOF=/usr/sbin/lsof ;; *) echo "no lsof command available on this OS!"; exit 1 ;; esac for i in $* do ${LSOF} -c java | grep -i $i | awk '{print $2}' | sort -u; done
