Programming with Transactions Testing Commits and Rollbacks Almost all commercial-strength DBMS software supports the ability to undo the effects of a transaction before those effects are committed to the database. This is particularly useful when an operation must be performed to completion or not performed at all. You may undo these effects on the data using rollbacks. This portion of the exercise will familiarize you with rollbacks and commits.

In this exercise, you will make use of common network tools. For each part below, capture the appropriate program output and include it with your answers to the questions. Part 1: netstat As a first step, modify the Web client that you wrote in Exercise 1 to count the number of bytes that it sends and receives. Name your modified client ModifiedClient.java. Next, use the command netstat -s to determine the values of the various counters that are maintained for the IP and TCP protocols. Finally, use your modified Web client to retrieve some Web pages and check the counters afterwards.
