General :: Command To Find Parent And Child Process?
Apr 21, 2011I have a script that calls other scripts/commands which may or may not spawn other process. From my understanding, when I do a ps -ef, the highest numbered process ID is supposed to be the parent ID of all the other related child processes, is this correct? In most or all circumstances, I do a ps -ef | grep <processid> of my script and anything that spawns off that process IDs I assumed are the child processes of my script. If I want to terminate my script and all other child processes, then I kill the parent ID which is the highest numbered PID and this will subsequently kill all other child process IDs, is this correct?
Now, my question is whether there is any quick way of showing what are the child processes of a parent ID instead of what am currently doing now which is visually checking which one is the parent ID and "assuming" that the highest numbered PID is the parent ID of all the other processes. Below is a sample output of running ps -ef | grep exp | grep -v grep. I assume from the output below that the parent process/ID is PID 11322, is that correct?
Code:
oracle 11154 11153 0 21:20 ? 00:00:00 /bin/sh -c (. ~oracle/.profile; /bin/ksh /usr/local/oracle/scripts/expdp_o
oracle 11155 11154 0 21:20 ? 00:00:00 /bin/sh -c (. ~oracle/.profile; /bin/ksh /usr/local/oracle/scripts/expdp_o
oracle 11190 11155 0 21:20 ? 00:00:00 /bin/ksh /usr/local/oracle/scripts/expdp_schema.ksh dev01
oracle 11322 11190 0 21:20 ? 00:00:00 expdp
General :: Sending Signal From Child Process To Parent Process?
Sep 8, 2010Code:
#include <stdio.h>
#include <unistd.h>
#include <signal.h>
[code]....
Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.

General :: Child Processes Of A Parent Process Occupying Socket Memory?
Jul 22, 2010I am facing an issue where the process starts hanging. When I closely look at the logs I come to know that some of the child processes that are forked by the parent process are not finished.
1) Is it possible that the child processes that are not finished occupy the socket memory of the parent process and ultimately a point is reached where no socket memory is available to fork new child processes.
2) What is the standard limit of socket memory in linux?
3) What is the fate of such child processes (as I have mentioned above)?
4) How to debug such cases so that the exact problematic area is identified?

Feb 24, 2010Code:
int main()
{
int pi;
int i=10;
pid=fork();
[code]....
Q 1. The value of the variable pid returned by the fork() function will be greater than 0 in the parent process and equal to zero in the child process? but during forking, there values are exactly copied so what's went wrong here?
Q 2. "changes to the variable in one process is not reflected in the other process" why it is so? >> Even if we have variable i declared as a pointer or a global it wont make a difference.
Code:
int main()
{
int i, pid;
i=10;
printf("before fork i is %d
[code]....
Q. Through this program it is clear that both process is using the data from the same location, so where's the original value is residing when the child process is in execution.?
Programming :: Splitting A Parent Process Into 2 Child And Then Merging Result?
Sep 15, 2010What i am trying to do is i want to add numbers from 1 to 100. but that too using multiprocessing. So i made a c programme and using fork() command made two child processes. Now in one child process i am adding from 1 to 50. and in another i am adding 51 to 100. and then in the parent process adding the two results to get the final one. Now the result from the two function i am getting correctly. But after the wait() call the value returned is lost : See the programme below for reference
# include<stdio.h>
# include<unistd.h>
# include<sys/wait.h>

Server :: Squid Parent: Child Process XXXXX Exited With Status 1?
May 24, 2010I have a transparent proxy Squid-3.0 on Slackware 12.2. I used cron to restart squid every day at 7:30 AM (just /path.to.squid/squid -k kill && /path.to.squid/squid) Some days ago I saw in /var/log/messages that Squid was killed but haven't started. I started it manually and everything was OK. But today everything repeated. And the log file is interesting. I tried to find about it on http://squid-cache.org/ but al in vain. This is from /var/log/messages :
Code:
May 24 07:30:02 konura squid[17188]: Squid Parent: child process 17199 exited due to signal 9
May 24 07:30:02 konura squid[19038]: Squid Parent: child process 19040 started
May 24 07:30:03 konura squid[19038]: Squid Parent: child process 19040 exited with status 1
May 24 07:30:06 konura squid[19038]: Squid Parent: child process 19045 started
[code]....
I need to say that I haven't edited the config file for a long time, but this problem started to happen. ADDED, Solved: I'm not sure, but maybe I found the decision. I deleted about 400 mb of Sarg logs from /var partition. And now squid runs well. Besides, before deleting old logs, 'crontab -e' and 'pkgtool' didn't work And the system wrote me that it's no space left on device. At the same time, 'df -h' showed me that all partitions had enough free space. Seems strange, but that's it. After deleting old proxy statistics, generated by Sarg (this is about 400 mb) 1)squid runs OK and 2)there are no more that annoying messages about abscence of free space.
