How to test Two-Phase-Commit
1 - create 3 files and for one of them remove the privileges RW. 
Thus it is possible to verify that one of the resources is unavailable and the 2PC trasaction will execute.
# touch /home/felipe/Temp/2FC/teste00.txt /home/felipe/Temp/2FC/teste11.txt /home/felipe/Temp/2FC/teste22.txt
# chmod 000 /home/felipe/Temp/2FC/teste11.txt

2 - Remove one of the files teste*txt. 
Thus it is possible to verify that one of the resources is unavailable and the 2PC trasaction will execute.
# rm -Rf /home/felipe/Temp/2FC/teste11.txt

3 - Create again the file excluded. Thus it is possible to test the trasaction until it completes.
# touch /home/felipe/Temp/2FC/teste11.txt
