Troubleshooting and Debugging Techniques Coursera

In this course, we’ll give you the tools to quickly identify and solve real-world problems that you might come across in your IT role. We’ll look at a bunch of different strategies and approaches for tackling the most common pitfalls of your code and IT infrastructure. You’ll learn strategies for approaching almost any technical problem and then see how those apply to solving different real-world scenarios.

We picked examples that include general system issues, issues with software that someone else wrote, and issues with programs that we wrote. We’ll talk about problems that can affect any operating system, and we’ll also look at challenges specific to certain platforms and scripting languages.

What Is the Best Java Debugger?

Many people might think this a simple question; I am not one of them. I feel that in the modern world of development, there are too many factors to pick a single tool for debugging any language, let alone Java.

In The Beginning

Let’s take a step back and look at where we started with debugging, and while I am not going to get into the history of debugging, we should look at some of the basic tools used for debugging Java, aside from logging and system-out.


Let’s start with a quick look at the Java debugger (Java Discovery Protocol - JDP), which is a command-line tool used for debugging Java applications. This tool ships directly from Oracle, so you can be sure it will work; however, it can be complex to use and require knowledge of where you want to debug ahead of time.

A positive aspect of this tool is the fact that you can use it on the same box where the Java Virtual Machine (JVM) is running. This set-up means you do not need to deal with the complexities of connecting any external service that might be restricted by firewalls, which is particularly useful if you are deploying your Java applications into Docker containers. (which let’s be honest, who isn’t).

And while a command-line tool is not the best option for everyday work, what other options are available?

Troubleshooting a Crash Triggered by Clang Compiler Optimization

If someone told you that the following C++ function would cause the program to crash, what would you think it is that caused the problem?


If you were given more descriptions, for example:

  • The crash reappears with a certain probability.
  • The error message shows Program terminated with signal SIGSEGV.
  • The backtrace information is usually incomplete or even missing.
  • When the optimization level is higher than -O2, the crash is more likely to happen.
  • The crash only happens while using Clang, but not GCC.
