Terminate process

hangyu — Tue, 21 Jun 2005 20:38:18 GMT

We have a system user "oracle_usr" always run some process in the system , but sometimes , these processes will not stop automatically until we terminate the process , can suggest the method how to terminate the process that is run by "oracle_usr" and run over 10 minutes ? thx

Just determine the process id and then issue the kill -15 command (NOT kill -9) to terminate the process.

It gets complicated if you want to do this automatically. There may be multiple processes, you wil have to verify you are killing the right process, etc,

You can do it as,

# ps -u oracle_usr | awk '!/PID/ { split($3,a,":");if (a[1]==10) { print $0 }}'

To kill them then,

# ps -u oracle_usr | awk '!/PID/ { split($3,a,":");if (a[1]==10) { print $1 }}' | xargs kill -9

hth.

Ok ..
Another way of doing would like this:
1.

# w
-bash-2.05b# w
6:50am up 1 day, 23:53, 2 users, load average: 0.00, 0.00, 0.00
User tty login@ idle JCPU PCPU what
oracle_usr pts/ta 6:28am 23:59 -bash
root pts/tb 6:50am w

From the command above i know that oracle_usr is associated with terminal pts/ta
then do :

2.
# ps -t pts/ta
-bash-2.05b# ps -tpts/ta
PID TTY TIME COMMAND
6226 pts/ta 0:00 -bash
6225 pts/ta 0:00 telnetd
-bash-2.05b#
This will display all the process associated with that user. Say i have to kill bash then:
3.
# kill -9 6226

This should work.

Try

ps -u oracle_user | grep -v PID | awk '{ split($3, a, ":"); if(a[1] > 10) print $1;}' | xargs kill -9
