WebSphere Application Server JBoss TCO analysisShetal Patel
This document analyzes the total cost of ownership of IBM WebSphere Application Server v8.5 compared to JBoss EAP v6 over a five-year period. It finds that WAS ND provides lower overall TCO than JBoss EAP due to advantages in stability, high availability, manageability, documentation and performance. Specifically, the TCO analysis shows WAS ND has a 35% lower total cost of ownership than JBoss EAP in large configurations. While JBoss EAP has a lower initial acquisition cost, the ongoing costs of administration, maintenance, downtime and other factors make it more expensive than WAS ND over the long term.

This document provides an overview of new features in Java 8, including lambda expressions, modularity with the Java Platform Module System, and performance enhancements with parallel array sorting and concurrency updates. It discusses the motivation and design of modularity in Java 8, how to compile and install modules, and differences from OSGi. Lambda expressions add support for operating on blocks of Java code. The presentation encourages attending to documentation, downloading SDKs, testing code, and providing feedback on the Java Technology Community site.
1) Java is a programming language created by James Gosling at Sun Microsystems in 1995. It is an object-oriented language designed to be portable and robust.
2) Java applications can run on many platforms due to its "write once, run anywhere" ability. This is enabled by the Java Virtual Machine, which converts Java code into code that devices can understand.
3) Java has several editions for different use cases, including the Java Standard Edition for desktop apps, the Java Enterprise Edition for enterprise software, and the Java Micro Edition for limited devices.
In this talk I give an overview of IBM's efforts to create a VM-agnostic toolkit of runtime components from the mature J9 Java Virtual Machine (JVM). I provide a summary of the motivations behind this project, talk about some important proof points with CPython and Ruby MRI, describe the motivations behind an open community for this technology, and discuss the many challenges with creating a runtime agnostic Just In Time compiler from the Testarossa Java JIT.
The document discusses Concierge, an OSGi framework designed for embedded devices. It has the following key points:
1. Concierge is an implementation of the OSGi dynamic module system that aims to have a small footprint suitable for embedded devices while maintaining compatibility with the OSGi specification.
2. Experiments show Concierge has a footprint of only 245kB, much smaller than other OSGi frameworks, while still supporting full OSGi R5 compatibility.
3. Concierge is designed to have usability in mind for embedded systems, staying close to OSGi standards with limited additional functionality and good integration between application behavior and framework events.
The document discusses best practices for running JVMs in containers. It recommends reducing container and application startup latency by minimizing layers and image sizes. The Java runtime can be optimized for containers by trimming modules, compressing files, and using lightweight operating systems. Class data sharing and GraalVM native images further improve startup times and footprints. The JVM should also behave in a container-aware way and the latest Java version should be used for security. Overall, following container security practices and choosing base images wisely is advised.

IBM continues to invest aggressively in its Java on System z technology with on-going deep vertical integration of Java with the z eco-system.
As such, the evolution of Java on Z shows consistent delivery of
deep co-design and exploitation of next generation hardware function,
industry leading runtime support with IBM J9 Virtual Machine, and
evolution of the Java language
demonstration outstanding and impressive release-to-release improvements in perfomance, consumability and function.
Language:
Java8 brings over 34 new significant language features to the Java. The two that are likely the most notable are
Lamdbas for streams and parallelism
Virtual extension functions for enabling transparent extension to existing libraries
z13:
New 5.0 GHz 8-Core Processor Chip – best single thread perf out there
480Mb L4 cache to optimize for data serving – best cache/thread ratio out there
Simultaneous Multi Threading (SMT) – two h/w threads/core allow independent execution of two software threads per-core. Provides more efficient use of core resources.
Vector Processing – Single Instruction Multiple Data (SIMD) to exploit data parallelism (array processing, strings, loops)
Crypto:
Public key function for Elliptic Curve Cryptography (ECC) accelerated by up-to 4X.
CP Assist for Cryptographic Function (CPACF) is hardware co-processor technology on the z chips. The IBM Java Crypto Engine (IBMJCE) in Java 8 leverages CPACF transparently to accelerate a significant set of crypto function.
This includes:
Block cipher algorithms: AES/DES/3DES
Block cipher modes: CBC/CFB/ECB/OFB
Secure hashing: SHA1/SHA2
JMX – Java Management Extensions
A new set of probes (Beans) have been added to enable precise CPU breakdown across
JVM System threads (JIT, GC etc)
JVM application threads
JVM monitoring threads
The importance of Java on System z
Java is a critically important language for System z. For data serving and transaction serving, which are traditional strengths of the z platform, Java has become foundational. For instance, WebSphere applications, written in Java and running on System z, provides a key advantage through co-location. The latter results in better response-times, greater throughput and reduced system complexity when driving CICS, IMS and DB2 transactions. Beyond this, as clients seek to extend and modernize their business logic, Java has become a language of choice for CICS, IMS and DB2 transactions.
Java is also critical for enabling next generation workloads in cloud, analytics, mobile and security (CAMS). Cloud and mobile applications can access data and transaction on z/OS using z/OS Connect (http://www-01.ibm.com/support/docview.wss?uid=tss1wp102439), and other WebSphere solutions – which are all inherently Java-based. IBM Operation Decision Manager (ODM) is written in Java. ODM is a platform for managing and executing business rules and business events to help make decisions faster, improve responsiveness, minimize risks and seize opportunities. The IBM MobileFirst Platform Developer Edition, formerly known as IBM Worklight Developer Edition, provides developers with the tools to quickly deploy mobile solutions using Java. System z Java also provides a full set of cryptographic functions to implement secure solutions.
A key strength of Java applications is the ability to immediately benefit from the latest hardware performance improvements using the Just In-Time JIT compiler in the latest Java SDK release.
Highlights for IBM Java 8 on IBM z13
IBM z13 and IBM Java 8 are taking Java performance to new heights! The combined benefits of IBM Java 8 and z13 features – including Single Instruction Multiple Data (SIMD) vector engine, Symmetric Multi-Threading (SMT) and improved CP Assist for Cryptographic Function (CPACF) -- are providing up-to 2X improvement in throughput-per-core for security-enabled applications and up-to 50% improvement for other generic applications.
Java 8 exploitation of System z CPACF is the default for System z9 and above on both z/OS and Linux on System z. The Java 8 SIMD exploitation requires z13 and z/OS 2.1 with PTFs. z13 zIIP SMT enablement also requires z/OS 2.1 with PTFs.

This figure shows the z/OS aggregate improvement in throughput from IBM Java 8 exploitation of cryptographic functions (CPACF), z13 SIMD, and z13 SMT for zIIPs.
Some highlights of the measurements show
1) a 40% improvement for zEC12 Java 8 versus Java 7 SR4, and
2) an additional 35% improvement for Java 8 z13 SMT versus Java 8 zEC12

* Beyond better caches and core technology for Java, we also have lots of innovative new architecture in zEC12. This includes
Hardware Transaction Memory:
IBM’s zEnterprise EC12 is the first general-purpose IBM server to incorporate transactional memory technology, first used commercially to help make the IBM Blue Gene/Q-based “Sequoia” system at Lawrence Livermore National Lab the fastest supercomputer in the world.
In zEC12, IBM adapted this technology to enable software to better support concurrent operations that use a shared set of data such as financial institutions processing transactions against the same set of accounts.
Runtime Instrumentation:
An innovative new facility used by the JVM to gather trace execution and heavy event data (d-cache-miss, branch miss etc) at runtime.
The information can be used by the JVM to adapt to the behaviour of the application more efficiently.
2 Gig Pages:
There has been a consistent noted trend for growth in Java application heap sizes. Today, it is not un-common to see heap sizes that are greater than 16G, with some customers using heaps that are on the order of 100G. 2G pages were added to help address this noted trend in growing storage.
1Meg Pageable Large Pages Using Flash Express
The JVM will exploit pageable large pages for the JIT code-cache and the object heap.
The use of 1M pageable large pages for the JIT codecache has been observed to enhance the runtime performance of some Java applications.
The use of 1M pageable pages for the object heap provides much of the same runtime performance benefits as non-pageable 1M pages, with the additional benefit of also offering better versatility for managing memory to improve system availability and responsiveness
The 1M pageable large page size is available only with the the following minimum requirements:
IBM zEnterprise EC12 with the Flash Express feature (#0402)
z/OS V1.13 with PTFs and the z/OS V1.13 RSM Enablement Offering web deliverable installed. The web deliverable is planned to be available at http://www.ibm.com/systems/z/os/zos/downloads/
Hints/directives
Enable more efficient use of the core resources for branch prediction and data/instruction cache hierarchy by the JVM
Traps
Reduce the overhead incurred by implicit checks (NULL and array-bounds) that are required by the Java language
Statement of Direction
IBM has made a statement of direction regarding exploitation of these features by the JVM
IBM plans for future maintenance roll-ups of IBM 31-bit and 64-bit SDK7 for z/OS Java(TM) Technology Edition, Version 7 (5655-W43 and 5655-W44) (IBM SDK7 for z/OS Java), to provide exploitation of new IBM zEnterprise EC12 features, including: Flash Express and pageable large pages, Transactional Execution Facility, Miscellaneous-Instruction-Extension Facility, and 2 GB pages. In addition, IBM SDK7 for z/OS Java is available for use by IBM middleware products running Java, such as IBM IMS 12 (5635-A03), IBM DB2 10 for z/OS (5605-DB2), and the Liberty profile of IBM WebSphere Application Server for z/OS v8.5 (5655-W65); and is planned for use by a future release of CICS Transaction Server for z/OS.
A multi-threaded benchmark that performs business logic for an online transaction processing framework. The benchmark incrementally increases the number of worker threads, hence increasing the system transaction processing throughput, up until the number of worker threads out-numbers the number of hardware threads (16-way).
zEC12 provides a 45% improvement in throughput to this benchmark
Java7SR3 provides an additional 13% improvement to this benchmark when exploiting the –Xaggressive and –Xlp options.
zEC12 and Java7SR3 provide an impressive 60% aggregate improvement to the Multi-threaded benchmark!
Linux on System z does not currently provide support for exploiting Flash Express for 1M paging. Performance improvements provided by Java7SR3 were a result of addition exploitation of fixed pages for backing the JIT code-cache when the –Xlp option is used.
