How to Increase Java Heap Memory Size in Ubuntu Linux JVM
 
03:17
This video explains How to Increase Java Heap Memory Size in Ubuntu Linux. I will show you how to use the -XX:+PrintFlagsFinal to find out your heap size detail. Running Java applications in computers takes some memory during the process which is known as Java memory (Java heap). Frequently, it is necessary to increase that heap to prevent throttling the performance of the application.

Languages offer a lot more than syntax and compilers. They often have supporting libraries and special facilities that set them apart from other languages. Some languages offer special compiler support for a particular construct, like tail call optimization, for example. Others provide interesting library support or capabilities. In this presentation we will dive into 12 cool things we can do with different languages on the JVM, things that are either impossible or hard to do in Java, but are quite easy and useful to realize in other popular languages on the JVM. If mixing these languages is an option on your projects, you'll have dozen more reasons after this presentation.

How to set and increase java heap size on Windows 7
 
04:31
In this video I tried to show how to set and increase java heap space on Windows 7. You can do it by specifying size with the runtime parameter on the java option in the control panel or by specifying the size in the VM argument on java Eclipse dynamically which works at runtime. However, if you want to make it persistent, you can make it from the clipse.ini file located in the Eclipse distribution directory. Just open the eclipse.ini file and scroll down to the bottom and specify the same argument which I have used in the video. Caution: don't increase heap size equal to the physical memory(RAM), otherwise your system might crash.

Between the many options for functional programming on the JVM, Frege is the only one that is pure. It follows the syntax and behavior of Haskell with super-strong type safety, Hindley-Milner type inference, higher-rank types, typeclasses, lazy evaluation per default, and announcing all effects in the type system. Frege is also unique in the way that it interoperates with Java: it does not compromise its language guarantees in terms of purity and type safety when calling into Java! Come and see how you can achieve pure functional programming on the JVM.

Building and Tuning High Performance Java Platforms
 
01:32:07
Recorded at SpringOne2GX 2015 Speaker: Emad Benjamin, VMWare Slides: http://www.slideshare.net/SpringCentral/building-and-tuning-high-performance-java-platforms This session will cover various GC tuning techniques and how to best build platform engineered systems; in particular the focus will be on tuning large scale JVM deployments. It is true that half of the world's Java applications have 2.x more hardware provisioned than what they really need, and 90% of these applications miss their SLA. In this session we showcase why this is the case, and demonstrate sizing techniques on how to platform engineer such systems without the need for over-provisioning and hence meeting SLA in a more feasible way. Come to this session to learn about GC tuning recipe that can give you the best configuration for latency sensitive applications. While predominantly most enterprise class Java workloads can fit into a scaled-out set of JVM instances of less than 4GB JVM heap, there are workloads in the in memory database space that require fairly large JVMs. We will look at various Java platform scales, some holding a few large JVMs of 90GB heap space, while other platforms are of thousands of JVM instances of less than 4GB heap space on each. We will also take a close look at an example XYZCars.com where a microservices approach was designed and deployed, we will talk through how to more correctly deploy microservices without out causing fragmentation of scale, and hence without impeding performance. In this session we take a deep dive into the issues and the optimal tuning configurations for tuning large JVMs in the range of 4GB to 360GB, using the GC tuning recipes that were gained over the past 15 years of GC tuning engagements. You should be able to walk away with the ability to commence a decent GC tuning exercise on your own. The session summarizes the techniques and the necessary JVM options needed to accomplish these complex tuning tasks, in addition to various virtualization best practices when dealing with such large Java systems. Naturally when tuning large scale JVM platforms, the underlying hardware tuning cannot be ignored, hence the session will take detour from the traditional GC tuning talks out there and dive into how you optimally size a platform for enhanced memory and CPU consumption.

OutOfMemoryError Java Heap Space Fix - Heap Dump Analysis VisualVM Tutorial
 
04:51
In this tutorial I show you how and why a java.lang.OutOfMemoryError can occur when running a Java application. I also show you how to configure your application to perform a Java Heap Dump if an out of memory errors. Additionally; I perform heap dump analysis by importing it into a Java profiling tool such as VisualVM. This will help find the root cause. First I set the Java Heap size to 64m by changing the –Xms and –Xmx virtual machine arguments. What does –Xms stand for? This java virtual machine argument allows you to specify the initial size (bytes) of the java heap. What does –Xmx stand for? This java virtual machine argument allows you to specify the maximum size, in bytes, of the memory allocation pool. We set the java heap memory to such a small size that it can’t handle and save the amount of java objects being created. Once there is not enough memory left to allocate objects, the application will fail with an out of memory error. I then configure the application to perform a Heap Dump on java.lang.OutOfMemoryError by specifying the flag: XX:+HeapDumpOnOutOfMemoryError This heap dump will be present in your applications working directory. If you would like to change the output path of the heap dump you can specify it by passing the: -XX:HeapDumpPath I then proceed to execute the java application which has an infinite loop that will create and place objects on an Array list. The application eventually fell over and threw an OutOfMemoryError when we allocated a Brick Object and tried to place it in the list. The list was at its maximum capacity and tried to resize. An arraylist is backed by an array, which has a finite number of elements. Each time the list’s backing array has reached maximum capacity it defines a new array typically double the size and copies the old array’s contents over into the new array. Then the GC clears the old array. Unfortunately there was not enough room for the new backing array in the Java Heap which caused the application to crash. When the java failure occurred it left the java heap with file name pattern java_pid{process-id}.hprof, this file can then be imported into VisualVM Java profiler for analysis of the applications state when the out of memory error occurred. After importing the hprof file into VisualVM profiler we can analyse the java thread’s status and the memory allocation. We can see the last stack trace before the failure and the huge amount of Brick allocations. If your application ever crashes, it’s good to inspect the heap dump to find out what was going on. This will hopefully identify causes and will prevent future failures if you can put a fix in. If you work with a cloud based ephemeral file system, then you might not be able to create / access a heap dump, as the application’s file system is scrapped and a new application is started on failure. There are ways to work around this such as attaching a hard drive to the instance. It depends on the nature of the system. I hope you enjoyed the tutorial!

JVM Mechanics by Douglas Hawkins
 
49:39
HotSpot promises to do wonders for us by Just-in-Time (JIT) compiling the "right" code for us, but how does it makes those decisions? And, perhaps more importantly, what happens when it's wrong? In this talk, you'll learn through real code examples just how the JVM decides to compile your code, deoptimize your code, and stop-the-world for a GC. Douglas Hawkins has been passionately developing software for the past 10 years -- creating applications for bioinformatics, finance, and retail. But Doug's true interest has always been VM internals. Now a VM engineer at Azul Systems, he works on Azul's Zing VM full-time and is the lead developer of Azul's ReadyNow technology.

JDD 2016: Concurrency options on the JVM (Christin Gorman)
 
37:22
Async and non-blocking are the concepts du jour when it comes to concurrency on the JVM. If you want to go web scale, if you want to maximize concurrent performance, you just cannot afford to block. But why? Blocking is not a problem in Erlang. Nor is it a problem in Go. How come we can't block on the JVM? And how does a non blocking request for data from a remote service actually work? I'll illustrate the whys, whens and hows with some simple code examples in plain java. Then I'll show you some practical examples of how to solve common programming problems in non-blocking frameworks like Vertx.io, Akka and Quasar. Is the future non-blocking, or should we all start learning Erlang? Come find out! JDD: http://jdd.org.pl/ Facebook: https://www.facebook.com/JDDconf/ Twitter: https://twitter.com/jdd_krakow

Tuning Large Scale Java Platforms
 
01:32:28
Recorded at SpringOne2GX 2014. Speakers: Emad Benjamin, Jamie O'Meara Slides: http://www.slideshare.net/SpringCentral/tuning-large-scale-java-platforms The session will cover various GC tuning techniques, in particular focus on tuning large scale JVM deployments. Come to this session to learn about GC tuning recipe that can give you the best configuration for latency sensitive applications. While predominantly most enterprise class Java workloads can fit into a scaled-out set of JVM instances of less than 4GB JVM heap, there are workloads in the in memory database space that require fairly large JVMs. In this session we take a deep dive into the issues and the optimal tuning configurations for tuning large JVMs in the range of 4GB to 128GB. In this session the GC tuning recipe shared is a refinement from 15 years of GC engagements and an adaptation in recent years for tuning some of the largest JVMs in the industry using plain HotSpot and CMS GC policy. You should be able to walk away with the ability to commence a decent GC tuning exercise on your own. The session does summarize the techniques and the necessary JVM options needed to accomplish this task. Naturally when tuning large scale JVM platforms, the underlying hardware tuning cannot be ignored, hence the session will take detour from the traditional GC tuning talks out there and dive into how you optimally size a platform for enhanced memory consumption. Lastly, the session will also cover Pivotal Application Fabric reference architecture where a comprehensive performance study was done.

Mozilla Firefox web browser is available for android, Chromebook, iOS(iPhone/iPad), Windows (Windows XP, Windows Vista,Windows 7, Windows 8, Windows 8.1,Windows 10,Windows Phone,Windows Server includes all 32bit and 64bit Version ), Linux ( Debian,Ubuntu((Ubuntu 16.10,16.10 (64-bit) ,16.10 (32-bit) , 16.10 Server (64-bit),16.10 Server (32-bit) 16.04.2 LTS,16.04.2 (64-bit) ,16.04.2 (32-bit) ,16.04.2 Server(64-bit) ,16.04.2 Server(32-bit) 14.04.5 LTS,14.04.5 (64-bit) ,14.04.5 (32-bit) , 14.04.5 Server (64-bit) ,14.04.5 Server (32-bit),Mint,openSUSE,Gentoo Linux,Fedora,Arch Linux,Slackware Linux,ALT Linux,Red Hat Enterprise Linux, Linux portable) Android, Chrome OS and Mac. Most browsers(chrome,opera,safari,edge and internet explorer) with new update don’t use java because of security issues related to java plugin vulnerabilities(if you are running old version then no problem but remember security risks of old browsers). If you try to run java you will get error your browser does not have java support. Even developer friendly Mozilla Firefox ended support for java(blocking java plugin/java not working), But Mozilla released ESR version for organizations and businesses which require java or jvm support so we are going to download Mozilla Firefox ESR(to unblock java/to turn on java). You can download ESR version for free, link is above. If you download Java before ESR and Java platform Plugin Is missing restart your PC or Install Java after you install Mozilla Firefox ESR to add java plugin. Follow this simple steps to use Java In Mozilla Firefox web browser 1) Open your web browser 2) Search Mozilla Firefox ESR in Google 3) Open Mozilla link (Link is available in description) 4) Click on download Mozilla Firefox ESR 5) Download Mozilla Firefox ESR 32Bit Version 6) Click Save File 7) Close your web browser after download finishes 8) Open setup file 9) Click Next 10) Select custom 11) Click next 12) Type Mozilla Firefox ESR (We are creating new separate folder for Firefox ESR) 13) Click Next 14) Rename existing/current Mozilla Firefox shortcut to Mozilla Firefox Main(to avoid confusion between two web browsers) 15) Click Next 16) Click Install 17) Rename new shortcut to Mozilla Firefox ESR 18) Click Finish INSTALL JAVA 1) Search Java download in Google 2) Open Java link 3) Click on free java download 4) Click on agree and start free download 5) Click save file 6) Close your web browser after download finishes 7) Open Setup file 8) Click Install 9) Install Java Enable Java 1) Open menu option 2) Click on add-ons 3) Click on plugins 4) Select always active in plugin option(allow java) VERIFY JAVA PLUGIN (to check if java is working or not) 1)Search verify java in Google 2) Open Java link 3) Click on Java Verify link 4) Click on run Done! you just enabled java in your web browser Contact Us : Facebook : https://www.facebook.com/SoftTrickChannel Wikipedia : https://en.wikipedia.org/wiki/User:SoftTrick Twitter : https://twitter.com/SoftTrickChnl Instagram : https://www.instagram.com/softtrick Reddit : https://www.reddit.com/user/SoftTricks Tumblr : https://www.tumblr.com/blog/softtrickchannel Desktop Wallpaper Photo Miguel Á.

Performance Tuning Where Java Meets the Hardware
 
58:10
There are three critical levels to performance-tuning Java applications. At a high level, the application needs to be coded in an efficient way. At runtime, the application needs to be allocated sufficient resources to avoid garbage collection. Finally, the JVM needs to generate efficient code for the processor to run. This presentation explains Java performance tuning, from the source code to the processor. Authors: Darryl Gove Darryl Gove is a senior principal software engineer in the Solaris Studio team, working on optimising applications and benchmarks for current and future processors. He is also the author of the books Multicore Application Programming, The Developer's Edge, and Solaris Application Programming.

Using FlameGraphs To Illuminate The JVM by Nitsan Wakart
 
52:12
FlameGraphs offer us a new way to visualize execution profiles, combined with Linux system profiler perf and the recently added -XX:+PreserveFramePointer option in JDK 8u60 we now have for the first time a way to capture a comprehensive profile for the OS, JVM and your Java code. In this session we will be exploring the JVM and Java applications using this new perspective and reflecting on the profiles and the utility of this new method: Introduction to FlameGraphs Old School? FlameGraphs using jstack and honest-profiler perf-map-agent + FlameGraphs + Java Java code left-right-center (oh yes you are so special my child!) Profiling the profilers Compilers ate my mother profile GC thrashed my dad profile And more advanced FlameGraphs usage as time permits!
