Compiling

• To compile all the java code go to the src folder, open a terminal and run sh ../scripts/compile.sh
• After that a build folder with all .class files will be created inside that src folder

Running

Inside the src/build folder:

1. Open a terminal and run rmiregistry to start the RMI needed for the TestApp

2. Open as many terminals needed for the number of peers and run sh ../../scripts/peer.sh <svc_access_point> <boot_address> <boot_port> -b to create the chord ring's boot Peer or run sh ../../scripts/peer.sh <svc_access_point> <boot_address> <boot_port> <peer_address> <peer_port> to create a normal Peer to join the ring

   • svc_access_point: Access point for RMI object.
   • boot_address: The address of the boot Peer
   • boot_port: The port of the boot Peer
   • peer_address: The address of the Peer to join the ring
   • peer_port: The port of the Peer to join the ring

3. Open a terminal for the TestApp and run sh ../../scripts/test.sh <peer_ap> BACKUP|RESTORE|DELETE|RECLAIM|STATE|SHUTDOWN [<opnd_1> [<optnd_2]]

   • peer_ap: Is the peer's access point for RMI object.
   • opnd_1: Is either the path name of the file to BACKUP/RESTORE/DELETE, for the respective 3 subprotocols, or, in the case of RECLAIM the maximum amount of disk space (in Byte) that the service can use to store the chunks.
   • opnd_2: This operand is an integer that specifies the desired replication degree and applies only to the BACKUP protocol

4. Finally, if you want to clean the created PeerStorage, open a new terminal and run sh ../../scripts/cleanup.sh

Testing Example

1. Open 1 terminal (TERMINAL1) in src folder
2. In TERMINAL1: sh ../scripts/compile.sh
3. Open 12 terminals (TERMINAL2, TERMINAL3, TERMINAL4, TERMINAL5, TERMINAL6, TERMINAL7, TERMINAL8, TERMINAL9, TERMINAL10, TERMINAL11, TERMINAL12) inside src/build folder
4. In TERMINAL2: rmiregistry
5. In TERMINAL3: sh ../scripts/peer.sh peer1 127.0.0.1 8001 -b
6. In TERMINAL4: sh ../scripts/peer.sh peer2 127.0.0.1 8001 127.0.0.1 8002
7. In TERMINAL5: sh ../scripts/peer.sh peer3 127.0.0.1 8001 127.0.0.1 8003
8. In TERMINAL6: sh ../scripts/peer.sh peer4 127.0.0.1 8001 127.0.0.1 8004
9. In TERMINAL7: sh ../scripts/peer.sh peer5 127.0.0.1 8001 127.0.0.1 8005
10. In TERMINAL8: sh ../scripts/peer.sh peer6 127.0.0.1 8001 127.0.0.1 8006
11. In TERMINAL9: sh ../scripts/peer.sh peer7 127.0.0.1 8001 127.0.0.1 8007
12. In TERMINAL10: sh ../scripts/peer.sh peer8 127.0.0.1 8001 127.0.0.1 8008
13. In TERMINAL11: sh ../scripts/peer.sh peer9 127.0.0.1 8001 127.0.0.1 8009
14. In TERMINAL12:
    • sh ../scripts/test.sh peer4 BACKUP ../files/1mb.jpg 3
    • sh ../scripts/test.sh peer4 STATE
    • sh ../scripts/test.sh peer4 RESTORE ../files/1mb.jpg
    • sh ../scripts/test.sh peer2 STATE
    • sh ../scripts/test.sh peer2 RECLAIM 10000
