I am planning to take up RHCE exam, but i have a doubt about the exam duration does it consist of 2 section where section 1 is for 2.5 hrs and section 2 is for 3 hours (total 5 1/2 hours) or does it consist of single section of 3.5 hours.
is there a resource/material that can simulate a RHEL on your personal machine so that one can practice for RH302 exam accurately? I am looking to practice sample questions with some kind of simulation environment where the scenario is similar to the real-time scenario that we can expect in the exam. For instance, the system is already broken with what is mentioned in the question so that I can focus only on solving the problem rather than breaking it first. I am looking for something specific to RHCE exam preparation/practice rather than using a tool like trouble-maker.
i've just appeared RHCE exam. i passed RHCT....but got only 36% in rhce part. but i configured all the servers correctly. i wrote shell script of iptables and i successfully run it. i wrote the following scripts....

I have a high priority service that I start with sudo nice -n -10 process. This process does not need superuser rights though, except for the priority elevation. But nice requires superuser privileges to elevate priority.
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
I expected to get the pid of child process, which the child process sent to parent process through the signal.
as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
I have a process running on Linux.When i do ps -eaf | grep <myProcess>, it show muliple entries for <myProcess> with different pids for each entry.Kindly tell me what could be the reason for a process having multiple pids?

I've been running my shellscript for about half an hour now. It's taking longer than I thought to process all the data. I have the process ID of it. Is it possible to save the process and log out then log in and continue the process? I know how to pause a process using kill -pause pID and continue it using kill -cont pID. But that only work if you don't log out after pausing it.
I have just bought a new DELL Studio 1555 laptop which has already Windows Vista- home edition in it,however I would like to install Red Hat Linux or Fedora on this laptop which can also support Oracle 10g.
Below is the link of the laptop to give you an overview of the configuration.
I want to kill parent process after "fork()" method. but if I kill parent process with "exit(0)" method, main() thread is terminated as well so child prosess doesn't work anymore. Is there any way to kill only parent process without affecting to child process?
I've some file with .sh extensions that runs some softwares.Now,how do I stop running that filesI know we run the command ./start_tomcat.sh to start the apache.Is there any command to stop that file/process or is it just kill the process to stop the process
I have a shell script to identify whether the process is running or not. If the process is not running, then I execute another script file to run my application. Below is my script and saved this script as monitorprocess.sh Code: #!/bin/bash
