JURN에서 Thread Dump 뜨는 방법.

Generating a Thread Dump with 1.3.x_x JRE/JDK

1. Use the command # ps -ef | grep jrun to find the JRun server process id:
   [root@linuxbox2 bin]# ps -ef | grep jrun
   root 9291 1 6 14:30 pts/1 00:00:05 ./jrun -start -nohup default
   root 9292 9291 0 14:30 pts/1 00:00:00 ./jrun -start -nohup default
   root 9293 9292 0 14:30 pts/1 00:00:00 ./jrun -start -nohup default
   ....................................................................................................
2. From the list of returned processes, find the process ID with a parent id of 1 -in this case it is 9291 (the parent process ID is listed in the third column, immediately after the process ID itself)
   ....................................................................................................
3. Using the java process id, send a kill - 3 signal as follows to cause the JVM to generate the thread dump (the kill -3 will not stop the process):
   [root@linuxbox2 bin]# kill -3 9291
   ....................................................................................................
4. Look in the dump-out.log for the output of the thread dump
