1 BEA WebLogic JRockit: Java Virtual Machine For Intel Server Platforms Arvind Jain Product Manager BEA Systems, Inc.

2 Customers Driving Paradigm Shift Towards Intel Servers Intel Servers Outpacing Single-Vendor RISC Servers Single-Vendor Platforms and Solutions Standards-Based Platforms and Solutions Improved price/performance Higher performance than RISC processors Available at fraction of cost of RISC-based servers Greater flexibility Standardized hardware building blocks Quickly scale infrastructure to handle growth Increased choice of H/W and O/S vendors HP World 2003 Solutions and Technology Conference & Expo page 2

3 Until Recently, Enterprise Java Was Not Considered Feasible On Intel Poor performance Java Virtual Machine not optimized for Windows and Linux on Intel servers JVMs optimized by H/W vendors for their own RISC systems Sun, IBM, HP, etc. No motivation to optimize for Intel servers Java App. JVM OS Hardware Java Code Translator Platform HP World 2003 Solutions and Technology Conference & Expo page 3

4 BEA WebLogic JRockit Changes The Game! WebLogic JRockit is the first independently available JVM optimized for Intel platforms, enabling high performance on low cost, standards-based infrastructure HP World 2003 Solutions and Technology Conference & Expo page 4

5 THE Benefits Of BEA WebLogic JRockit 8.1 Industry Leading Performance The highest performing JVM on Intel architectures for both Windows and Linux! Industrial Strength Reliability Continued high performance of applications under heavy user and transaction loads Unique Monitoring Capabilities Real-time monitoring of Java applications the JVM is no longer a black box Java App. WebLogic Platform JRockit Win/Linux IA32/IA64 Lower TCO!

6 BEA WebLogic JRockit Vision The Java Operating Environment 1 Focus on enterprise applications 2 Enable true hardware independence 3 100% compatible with J2SE specs. HP World 2003 Solutions and Technology Conference & Expo page 6

7 WebLogic JRockit Is A Critical Part Of The BEA Enterprise Application Platform Integrated Development Environment BEA WebLogic Workshop User Integration BEA WebLogic Portal Data Integration BEA Liquid Data for WebLogic Application Framework BEA WebLogic Workshop Application Server BEA WebLogic Server JVM BEA WebLogic JRockit Process Integration BEA WebLogic Integration Bundled as part of BEA WebLogic Server 8.1 and WebLogic Platform 8.1 Freely downloadable as a standalone product HP World 2003 Solutions and Technology Conference & Expo page 7

8 The Java Operating Environment Optimize ALL parts of the VM Typical Client VMs Code generation R R Memory management TM MM Thread management IO I/O Reflection CG Full adaptive optimization TM Runtime behavior of applications Heap size, lifetime, # threads, network & IO activity, pause times Underlying OS & H/W # CPUs, CPU architecture, OS threading model, available memory Break open the black-box Real-time application monitoring & management 100% compatible with J2SE and switchable with other JVMs Typical Server VMs CG MM HP World 2003 Solutions and Technology Conference & Expo page 8

9 Flexible Design To Suit All Applications Dynamic code generation No interpreter JIT compile methods at startup for high performance Dynamically optimize frequently called methods Multiple garbage collectors High throughput, but can tolerate some pauses No pauses, but sacrifice some performance Generational Handle temporary & long-lived objects differently Multi-CPU scalability Parallel Concurrent No pauses HP World 2003 Solutions and Technology Conference & Expo page 9

10 Manageability Features Built-in framework for real-time monitoring and management Monitor application & system performance Supervise JVM health to avoid catastrophic failures JVMDI to support debugger tools JVMPI to support profiling tools Management console for remote monitoring Java Management APIs exposed via JM interface through WLS console HP World 2003 Solutions and Technology Conference & Expo page 10

11 Real-Time Management Console Monitor GC pauses, memory usage, CPU usage, thread tracking Get callbacks before OutOfMemory Manage Thread-CPU binding Dynamic code optimization On/Off Method Profiler Monitor method invocation Time spent in methods Exception Count Track method exceptions Notification Rules-based notification HP World 2003 Solutions and Technology Conference & Expo page 11
