- 3. Description: ■ Focus of the training is to make JVM and Java performance tuning clear and simple as possible for the participants at the design, architecture and, implementation levels. This is an end-to-end training. The Training illustrates almost every concept with the help of pictures because it is much easier to understand the concept pictorially and model code. There are a lot of illustrations in the course of the training. There are worked out examples to illustrate the concepts for almost every topic. There is a detailed case study that strings together all concepts and technology. Intended Audience: ■ ■ The target group is programmers who want to know foundations of concurrent programming and existing concurrent programming environments, in order, now or in future, to develop multithreaded applications for multi-core processors and shared memory multiprocessors. Java Consultants, developers or anyone with Java experience interested in performance testing. Prerequisites: ■ ■ ■ ■ Some experience with distributed technologies. Good Knowledge of Java. Working knowledge of any database Workstation with JDK 1.7.0 installed Instructional Method: ■ ■ This is an instructor led course provides lecture topics and the practical application of Java and the underlying technologies. It pictorially presents most concepts and there is a detailed case study that strings together the technologies, patterns and design. m
