Linux Os Clustering?

hello

I want to setup two desktops each one having 4 cores and combine them to have 8 cores with linux clustering. Is this how clustering works and what level of difficulty is it?

Also, any good howto sites on the subject is appreciated. Thanks

can anyone please send me the clustering code of nodes in ns2?? THank you in advance

how can i add k-means algorithm on zrp protocol ?????? in ns2?
I want to add k-means clustering alg. for ZRP protocol to make it run with the inter-zone routing protocol for inter clustering and with intra-zone for intra clustering. note that i am using ns-2.35/ubuntu10.04 and the ZRP was completely added to the simulator

Hello,

I'm looking for options/tools where I can get server performance counters for Linux OS (having Java application on it). For windows based platforms, we have PerfMon that provides this data. I'm looking for a similar tool for Linux platform java apps. Could you please help me in identifying the best options to get the performance related data like Perfmon?

Thanks,

I'm new to linux but I use linux a little at school and by connecting through a shell at home. Anyways, I just installed linux a little while ago and I opened a shell and tried to compile some java code by going to the directory of the code and typing "javac someCode.java" like I do at school but it says the command is not found.

I previously had installed the java runtime environment and I just went to go and try to install the java development kit but it says it was already installed.

Is there some sort of path I need to set for the shell to look for the java compiler? Thanks in advance.

Edit:
I have added aliases to my .cshrc file at school and I just found a bashrc file and csh.cshrc file in the /etc folder. Sorry, I'm really new to all of this. Anyways, I'm geussing I have to edit the bash file? Can anyone point me to a good tutorial of scripting for these files???

HI,
When I first joined this forum I made a fairly long synopsis of who I am and what I wanted to do with Linux. I thought I posted it but now I can not find it anywhere. No doubt I messed up somehow!

I am developing a Java stand alone application that will require some server side Java Servlets to manage the marking, registration, install and deployment phases. I have a spare Windows 7 PC that I have converted to the Debian Linux system successfully...

I currently use LunarPages as my ISP and host to 3 domains. If I use them to host my Server Side processing they use Resin 3.x for the web server and my contract with them provides me with one 'MySQL' database system...

Next on my own server I will install the Resin version that LunarPages requires along with their required version of the Java EE.

I have 3 ways to eventually deploy my Java stand alone application
1. Use LunarPages to host my Server Side Servlet command...
2. Use the Google AppEngine service...
3. Use my own Linux Server for deployment purposes...

This message is an intro and does not have any specific question yet...
Perhaps someone may offer some suggestions for me or critique my objects...

Regards,

Jim Crowell

I have configured RHEL cluster by installing ricci and luci server. I have successfully tested it for httpd service. Now my target is to achive the HA of python. Can anyone help me with it?

hello can i get source code of multi hop clustering for wsn in ns2

Hy All,

I have two nodes running RHEL 6.4 which are in cluster. I have clustered httpd service. Now I have certain application suppose X which reside in SAN partition. Now my job is to only automate this script to run by analyzing httpd status. I have successfully created the script apptrigger.sh whose content is given below,

-bash-4.1$ cat apptrigger.sh
a=0
b=0
c=0
d=0
a="service httpd status"
b=`eval $a`
##### CHECKING WHETHER HTTPD SERVICE IS RUNNING OR NOT #####
if [ "$b" != "httpd is stopped" ]; then
c="bash /switchapp/switch/ezlinkenterprise/bin/ezlink-cluster.sh status"
d=`eval $c`
##### CHECKING WHETHER EZ IS RUNNING OR NOT #####
if [ "$d" != "EzTaskMgr is Running" ]; then
ezstart
fi
fi

I have created this script in say test user. Now when I put this script to automate or run every minute through test user and defined its value in crontab -e of test user whose content is as shown below
$crontab -l
* * * * * /bin/bash /home/test/apptrigger.sh

but this script is running as root user so I cannot get the o/p
I think some environment variable need to be set. Anyone can guide me with this step? Thanks for your views and suggestion.

hello Experts!
need some help here with python FTP. so what i'm trying to do is, from a linux machine, ill be sending over a python script to a windows machine via python ftp. that works fine with no problem. now, i want to execute that python script i sent remotely. im having trouble with that. here's my code to just execute the script:

p.s : please dont suggest other options such as python paramiko due to many network security reasons

Code:

ftp = ftplib.FTP("windows machine name")
ftp.login("username", "password")
ftp.cwd("where\\python\\script\\is kept\\")

ftp.sendcmd("python myscript.py")

but looks like it doesn't recognize that command. how do i accomplish this please?
