Project: Architecture and performance of computer systems

To launch the project first you have to make sure that the data folder exists in the Server directory:

mkdir -p Server/data
cp path_to_database_file/dbdata.txt Server/data

Then spin up all the virtual machines:

vagrant up

Now you can connect to the Server through ssh and launch the application:

vagrant ssh server
#In the virtual machine
nohup dstat -tcmnps  --output /home/Server/notImproved/$(hostname)Stat.csv &
export _JAVA_OPTIONS="-Xms512m -Xmx1024m"
cp -rf ../Server/* /home/vagrant
javac ReadFile.java 
javac Server.java 
java Server 4999

And after the database is loaded(You should see "Database Loaded!!!" in the output of the server), you can run the clients:

vagrant ssh client1 #There are 2 clients so you have to connect also to the client2
nohup dstat -tcmnps  --output /home/Client/notImproved/$(hostname)Stat.csv &
export _JAVA_OPTIONS="-Xms512m -Xmx1024m"
cp -rf ../Client/* /home/vagrant
javac Client.java 
java Client 10.0.0.10 4999 /home/Client/notImproved/serviceTime$(hostname).csv

Configure the latency:

sudo tc qdisc add dev eth1 root netem delay 10ms

If you want to destroy all the virtual machines:

#In the host machine
vagrant destroy up
