Java_RMI

Overview

In this project we have three machines, the first machine represents the client that reads an integer N and then sends values from 0 to N to the server1 and the server2. Server1 is responsible for computing the Fibonacci values of a given number and returning it back to the client. The server2 is responsible for calculating the square values of a given number and also returning it back to the client. These operations work concurrently.

Example

Let's say the client reads the number 5 as N, it sends 0 then 1, then 2...5, it will receive the Fibonacci numbers of these values and their squares at the same time.

Deployment

In my case, I have an Ubuntu Linux distribution as an OS. Also, I have created two separate Windows 10 virtual machines. These 3 machines are connected over my home's LAN network, each one has its own IP address.

How to run the project?

First of all, you must compile the code by entering the project directory and running the following command:

  javac *.java

After that you open a terminal (CMD in case you are using Windows) in each machine, for machine 1 and machine 2 you run server 1 and server 2

  java Server1
  java Server2

for machine 3 (client), you pass the IP addresses of the servers as arguments like this:

  java Client 192.168.1.9 192.168.1.25

in order to get the ip address of a specific server, you just need to open a terminal and type:

  ifconfig

or "ipconfig" in case you are using windows
