Analysis of Component based Computing

To achieve a precise goal of components on different platforms that are presented the some components in order to co-operate with one another over a communication network. The component should be able to access services provided through remote, location transparent service in vocations.The major role of component-based method is represent an ideal framework for component-driven in client/server computing. One of the good implementation examples of broker architecture is Common Object Request Broker Architecture (CORBA). The component based technologies discuss the proposal of distributed object of CORBA which is the Object Management Group’s (OMG).This paper proposes the broker architecture as CORBA has distributed system that can be demonstrated by client-server architecture which practices the base for multi-tier architecture.

Trace Crawler

The Object Request Broker (ORB) manages the interaction between clients and servers using the Internet InterORB Protocol (IIOP). The ORB trace file comprises of messages, trace points, and wire tracing. These trace files are usually large and at times they can grow to 1-2 GBs. For debugging an ORB problem, the developer must determine whether the problem is in the client or in the server of the distributed application. Typically during debugging process, developer have to switch between source codes and trace logs back and forth multiple times. Often browsing the right source code file, opening it in the IDE and then moving to the line from where the trace is originated. This work proposes a tool which will help developers and service engineers to browse through source code and corresponding trace by providing integrated framework. The Aim of the tool is to build an application to parse and analyse ORB trace files. The application will fetch relevant details for the failing entries, and will perform the preliminary analysis. In this way a lot of time and human effort can be saved. The customers such as defense, military organizations can themselves view relevant details about the failures of their application by this tool, without having to compromise on confidentiality with minimal effort and time.

ANALISIS KINERJA KOMPUTASI TERDISTRIBUSI DENGAN PLATFORM WEB SERVICE MENGGUNAKAN METODE REST REPRESENTATIONAL STATE TRANSFER

Teknologi Komputasi terdistribusi seperti Common Object Request Broker Architecture (CORBA), Distributed Component Object Model (DCOM), Remote Method Invocation (RMI) memiliki ketergantungan terhadap platform sistim operasi dan tidak memiliki kemampuan interoperabilitas sehingga memerlukan infrastruktur yang kompleks untuk diimplementasikan pada proses integrasi data. Teknologi layanan web (web service) adalah teknologi yang dapat menyelesaikan permasalahan interoperabilitas antar aplikasi yang berbeda platform baik perangkat lunak, sistim operasi maupun bahasa pemrograman. Penelitian ini difokuskan untuk menganalisis kinerja sebuah web service dengan mengukur kemampuan web service metode rest pada proses transaksi data. Parameter yang digunakan dalam mengevaluasi kinerja adalah pengukuran lama waktu yang diperlukan dari pengiriman permintaan oleh klien sampai klien menerima hasil permintaan tersebut dari server atau biasa disebut user perceived latency. Sedangkan pengujian dilakukan pada 3 buah web server yang memiliki perbedaan arsitektur. Hasil Analisis menunjukkan metode REST memerlukan desain yang memiliki struktur data secara terperinci agar eksekusi klien dapat dijalankan dengan baik oleh server, selain itu web server nginx menjadi web server yang terbaik dalam mengeksekusi service terutama web service dengan metoda REST.
