Is it necessary to provide the port number in the JDBC url while connecting to mysql?
if its provided then i can use it . but if its not provided and i do hostname -f it only gives the hostname , what about the port number .
i have been doing my practice where i donot use portnumber.
but in certification is port number mandatory?
if yes will they be providing it , if they wont be providing the how to get the portnumber.
thanks in advance.
