Everyone who is using Oracle Weblogic must had a thought like “Where the *** is the stop script to kill my nodemanager proces”…. Well, i did. So i wrote a simple stop script which can be better probally, but it does the job.
#!/bin/bash
PID=`ps -efw | grep -i "Xms128m" | grep -i nodemanager | awk '{print $2}'`
if [ ! -z $PID ]; then
echo "Killing nodemanager with PID: $PID"
kill $PID
CHECK=`ps -e -o pid | grep $PID`
if [ -z $CHECK ]; then
echo "Nodemanager stop success"
fi
else
echo "No nodemanager process running"
fi
Remember to copy this snippet into a bash file and set the correct permissions.
Some developers like to stop nodemanager programmaticly. I.E.
Note: You could use it to stop and start adminservers for example…
You could use following python definitions:
# RETURN LIST OF PROCESS IDS FROM GREPING PROCESS COMMANDS
def psgrep(str):
pat = re.compile(str)
cmd = "ps -e -o pid,command"
lines = shlines("ps -e -o pid,command")
pids = []
for line in lines:
cols = string.split(line)
if cols[1] == "grep": continue
for col in cols[1:]:
if pat.search(col):
pids.append(cols[0])
continue
return pids
def stop_process_tree(ppid):
time.sleep(1)
pids = get_child_processes(ppid)
while len(pids) > 0:
for pid in pids:
stop_process_tree(pid)
pids = get_child_processes(ppid)
kill_process(ppid)
return
def kill_process(pid):
if pid == None or pid == '':
return
time.sleep(1)
if shout("ps -o pid= --pid " + pid) != '':
os.system("kill " + pid)
for i in range(30):
time.sleep(1)
if shout("ps -o pid= --pid " + pid) == '':
return
os.system("kill -9 " + pid)
for i in range(30):
time.sleep(1)
if shout("ps -o pid= --pid " + pid) == '':
return
error("Cannot kill " + pid)
return
def get_child_processes(ppid):
return string.split(shout("ps -o pid= --ppid " + ppid))
