Mission-Critical Java
EXECUTIVE OVERVIEW Technology barriers that once prevented enterprises from adopting Java-based The Oracle JRockit family of products is a approaches for mission-critical applications with extreme, predictable computing comprehensive portfolio of Java runtime solutions that leverages the base JVM- needs have been breached. Recent advances throughout the entire Java stack put Oracle JRockit-the world's fastest Java in a position to power the next generation of enterprise computing. Now JVM, as shown by numerous customers can reap the benefits of a Java-based infrastructure, including higher industry benchmarks. developer productivity, fewer defects, a proven kernel, and adherence to standards.
The Oracle JRockit family of products is a comprehensive portfolio of Java runtime solutions that leverages the base Java Virtual Machine (JVM)-Oracle JRockit-the world's fastest JVM, as shown by numerous industry benchmarks. The benefits delivered by the Oracle JRockit family of products include . Predictable and extreme latency performance. Guaranteed acceleration of application execution . Zero coding. Ability to swap out any JVM with zero coding and minimal configuration for instantaneous performance improvements . Advanced management tools. Ability to monitor and tune in-production JVM and application performance with no performance penalties
INTRODUCTION A JVM operates at the lowest, but extremely important, layer of the Java computing stack. It is the cornerstone of the Java platform-the technology responsible for Java's hardware and operating system independence. The JVM's processing capacity, predictability, memory management, and management infrastructure are critical to the success of the higher layers of the Java stack. Oracle JRockit Real Time is the industry's fastest real-time solution for standard Java. The leading Java runtime solution for latency-sensitive applications, Oracle JRockit Real Time provides JVM response times in milli- and microseconds, based on its unique and innovative deterministic garbage collector, for automatic memory management. Suitable for the needs of highly time-sensitive applications such as in financial front offices, military command and control, and telecom networks, this new capability allows the use of Java technology where it used to be impractical. Oracle JRockit Mission Control provides a suite of nonintrusive monitoring and debugging tools designed to deliver a rich set of operational information with minimal overhead-making application profiling and application debugging possible in production environments.
Mission-Critical Java Page 2 EXTREME AND PREDICTABLE PERFORMANCE WITH JAVA The Oracle JRockit family of products is designed to optimize the performance of mission-critical applications with extreme and predictable computing needs. The software offers innovative, highly efficient optimization algorithms and intelligent memory management solutions to achieve predictable response performance and the highest-possible throughput while delivering industrial-strength system stability and reliability under heavy user and transaction loads.
Extreme Performance with the World's Fastest JVM, Oracle JRockit The Oracle JRockit JVM continues to raise performance standards with record-setting published benchmarks; a smaller memory footprint; quicker startup; a larger possible object heap; and adaptive, self-healing memory management-plus solid core processing that brings systems closer to zero downtime. Oracle JRockit provides continuous performance improvement in real time-from Oracle JRockit provides continuous initial deployment throughout the life of the application. It automatically adapts its performance improvement in real time-from initial deployment throughout the life behavior to the operating conditions of the application and the underlying of the application. It automatically adapts environment to deliver optimal performance, scalability, and reliability. The its behavior to the operating conditions of software compiles each method the first time it encounters it, generating machine the application and the underlying code with platform-specific optimizations. For more-aggressive optimization, it environment to deliver optimal then monitors an application as it executes and identifies the methods on which it performan... [download for more]
