This repository implements simple fault tolerance and 2 phase commit protocol in distributed banking service

Distributed Banking Service

This project implements distributed banking service to show how 2-phase commit protocol, and simple fault torelence mechanism work.

Steps to execute the project

1. Build the project and generates server and client executables

   • make compile

2. Start the backend servers first.

   • ./bin/server <IP ADDRESS> <BACKEND PORT>

   NOTE: Before starting the servers, make sure you have entered port numbers in portsfile.txt.

3. Start the frontend server first.

   • ./bin/front <IP ADDRESS> <FRONTEND PORT>

4. Run client

   • ./bin/client <IP ADDRESS> <FRONTEND PORT>

5. To clean all object and executable files

   • make clean

OR

You can also use exe-script.py to run the project. This script will create 5 new terminals- 1 for client, 1 for frontend server, and 3 for backend servers. Above all shell commands will get executed automatically thus starting client, frontend server and backend servers. After running this script successfully, you will MENU in client’s terminal.

NOTE: This script creates portsfile.txt with backend server ports.

Steps to run the script:

1. make compile
2. python3 exe-script.py <IP ADDRESS> <FRONTEND PORT>

Example: If you take frontend server’s port=8080 then the script will create port numbers 8081, 8082, 8083 for 3 backend servers. IP ADDRESS will remain same for each. (Python version used: 3.8.9)

3. make clean
