This experiment simulates the Two-Phase Commit protocol. Follow these steps to conduct the experiment:

1. Configure the Transaction:

   • Select the Number of Participants from the dropdown menu.
   • Choose a Failure Scenario to simulate. Options include coordinator or participant failures in either phase, network partitions, or timeouts.

2. Control the Simulation:

   • Adjust the Animation Speed to control the simulation's pace.
   • Select the Simulation Mode:
     • Step-by-step (Manual): Use the "Next Step" button to advance the protocol one step at a time.
     • Automatic: The simulation runs automatically. Use the "Run Simulation" button to start.

3. Observe the Simulation:

   • The Simulation Area visually represents the coordinator, participants, and messages.
   • The Phase Indicator shows the current phase of the protocol.
   • The Transaction Log displays a detailed log of all actions and state changes.
   • The Transaction Statistics panel shows counts of successful commits, aborts, and failures.

4. Run Scenarios:

   • Start with the "No Failures" scenario to understand the normal workflow.
   • Run each of the failure scenarios to observe how the protocol handles them.
   • Use the "Reset Simulation" button to start a new simulation.
