Course Overview

Java Mission control primarily monitors the state of multiple running Java Virtual Machines (JVM) and analyze Java Flight Recorder files. Java Mission control includes JMX console and Java Flight Recorder. JMX console is used by JMC to communicate with remote Java processes.  The Java Flight Recorder is for profiling and it also provides information about the operating system, the JVM and Java application running on the JVM.

The Java Performance Tuning using Mission Control and Flight Recorder course makes you understand how the Java Garbage Collection works inside the JVM and makes you try out the new G1 Garbage collector.

Course Content

Lesson 1: Introduction
This session lets you understand the need to learn Java performance tuning using mission control and flight recorder. You will be engaged in classes demonstrating

1.1: What is Java Mission Control?
1.2: What is Flight Recorder?
1.3: What is Java Virtual Machine? 

Lesson 2: Java Virtual Machine
This lesson teaches the fundamentals of Java Virtual machine and performance. Following chapters are covered in this lesson

2.1: Overview of JVM
Java Virtual Machine is a specification that provides a runtime environment for executing Java bytecode. JVM is platform independent.
Functionalities of JVMLoads Code
Verifies Code
Executes Code
Provides runtime environment

2.2: JVM Architecture
The JVM Architecture supports features for high performance and massive scalability.
JVM Components
The three JVM components are Heap, JIT compiler, and Garbage Collector

Lesson 3:  Performance Overview  
The performance tuning of any system is dependent on responsiveness and Throughput. Responsiveness refers how quick a system responds and Throughput refers to maximizing the amount of work within a particular period.

Lesson 4:  Java Garbage Collection

4.1: Introduction to Java Garbage Collection
Java Garbage collectors find unwanted objects and remove them. The Java developers do not eliminate the memory in the program code, and the Garbage collectors remove this unnecessary objects and open up space for memory.

4.2: Basics of Garbage Collection
Basics of Garbage collection involves the process of understanding about heap memory, identifying used objects  and deleting the remaining objects

4.3: The GC Aging Process
This section explains about the different generations in the Garbage collections namely young generation, old generation and permanent generation

4.4: G1 GC
The G1 Garbage Collector is for multi-processor machines with more memories.

Lesson 5: Java Garbage Collectors
This lesson explains the GC algorithms, different Collectors and the usage of Ergonomics

5.1: Garbage Collecting Algorithms
All GC Algorithms work first to find out all the objects that are alive. Once this is complete, they identify the unwanted or dead objects and remove them.

5.2: Types of GC Collectors
There are three different types of Garbage Collectors

Serial Collector
Parallel Collector and
Concurrent Collector

5.3: JVM Ergonomics
The concept of Ergonomics is introduced to provide excellent performance with no tuning of command line required by selecting options like garbage collector, heap size and runtime collector

Lesson 6: Command Line JVM Monitoring
This lesson explains you the basic command line options and the key command line options available for use along with the monitoring options listed below

6.1: GC Monitoring
6.2: JIT Monitoring

Lesson 7: Mission Control and JVM Monitoring Tools
Mission Control helps monitor data with the lowest possible impact on the running application. Java VisualVM is a graphical user interface to provide detailed information about Java application that runs on a JVM.

7.1: Monitoring with VisualVM
7.2: Monitoring with Mission Control

Lesson 8: Java Flight Recorder
Java Flight Recorder is used for profiling data and causes no overhead in performance. This lesson teaches you about

8.1: JFR Architecture
8.2: Uses of JFR
8.3: Creating Flight Recordings
8.4: Analyze Flight Recording

Lesson 9: Monitoring Operating System Performance
Monitoring Operating system performance depends on the underlying host operating system, the operational database, and messaging infrastructures

9.1: Monitoring CPU Usage: Indicates CPU Utilization
9.2: Monitoring Memory Usage: Indicates physical memory available or in use
9.3: Monitoring Network I/O: Indicates rate of data transfer on the Networks
9.4: Monitoring Disk I/O: Indicates Disk space available or in use
9.5: Monitoring Processes: Indicates resource utilization by process

Lesson 10: Performance Profiling Tools
The performance profiling tools allow increasing the productivity by improving the Java Code.

10.1: Overview of Profiling Tools
10.2: CPU Profiling
10.3: Heap Profiling

Lesson 11: Troubleshooting Performance Issues by Profiling
This lesson details you how to troubleshoot performance issues by

11.1: Memory Leak Profiling
11.2: Detecting Memory Leaks
11.3: Detecting Contention and Locking Issues

Lesson 12: Garbage Collection Tuning
12.1: Tuning with Serial GC
Tuning with Serial GC is achieved using mark-copy for Young generation and mark-sweep-compact for the Old generation. These are single-threaded collectors, incapable of parallelizing the task. 

12.2: Tuning with Parallel GC
Parallel Garbage Collector is suitable on multi-core machines in cases where your primary goal is to increase throughput. You can achieve higher performance due to more efficient usage of system resources.

12.3: Tuning with Concurrent GC
Tuning with Concurrent GC is achieved using mark-copy for Young generation and mark-sweep-compact for the Old generation. The design of this collector avoids long pauses while collecting in the Old Generation.

12.4: Tuning with G1 GC
G1 is the most advanced production-ready collector available in Hot Spot. It is being improved by the Hot Spot Engineers, with new optimizations or features coming in with future Java versions.

Lesson 13: Language Level Concerns and Garbage Collection
This chapter teaches the methods of allocation and providing references

13.1: Object Allocation
13.2: Working with Large Objects
13.3: Explicit Garbage Collection
13.4: Finalizers
13.5: Memory Leak Detection Tools
13.6: Object References
