How many layers are in RMI architecture?
The RMI system consists of three layers: the stub/skeleton layer, the remote reference layer, and the transport layer.
What is RMI architecture?
The RMI architecture, shown in Figure, describes how remote objects behave and how parameters are passed between remote methods. Remote method invocation allows the program to define separately the behaviour and the code that implements the behaviour and allows running them on separate JVMs.
What is an RMI form?
Remote Method Invocation, an application-programming interface used in Java environments. .rmi , a file extension for a RIFF MIDI file.
What is remote reference layer in RMI?
The remote reference layer is responsible for carrying out the semantics of the invocation. For example the remote reference layer is responsible for determining whether the server is a single object or is a replicated object requiring communications with multiple locations.

What is RMI in Java Mcq?
What is Remote method invocation (RMI)? Explanation: Remote method invocation RMI allows us to invoke a method of java object that executes on another machine.
What is RMI in distributed system Mcq?
This set of Java Multiple Choice Questions & Answers (MCQs) focuses on “Remote Method Invocation (RMI)”. 1. What is Remote method invocation (RMI)? Explanation: Remote method invocation RMI allows us to invoke a method of java object that executes on another machine.
What are the different types of classes that are used in RMI?
What are the different types of classes that are used in RMI?
- Remote class:
- Remote class object:
- Serializable class:
- Serializable class objects:
What is the responsibility of transport layer in RMI architecture?
In general, the transport layer of the RMI system is responsible for: Setting up connections to remote address spaces. Managing connections. Monitoring connection “liveness.”
What are the components of RMI architecture?
Architecture of an RMI Application In an RMI application, we write two programs, a server program (resides on the server) and a client program (resides on the client). Inside the server program, a remote object is created and reference of that object is made available for the client (using the registry).
What are the modules in RMI architecture?
Your RMI framework must include the standard RMI modules, i.e., communication module, proxy, skeleton, dispatcher, and remote reference module as discussed in the class and described in Chapters 4 & 5 of the book Distributed Systems: Concepts & Design by Coulouris et al (henceforth referred to as CDK3).
What are the layers of RMI architecture?
What are the layers of RMI Architecture? – The three layers are the Stub and Skeleton Layer, the Remote Reference Layer, and the Transport Layer. – The stub and skeleton layer is responsible for marshaling and unmarshaling the data and transmitting and receiving them to/from the Remote Reference Layer.
What is RMI architecture in Java?
In distributed application architecture, it is always a need for communication between two different applications. In Java-based applications, one application communicates with another remote/different application running somewhere else by using a mechanism called RMI architecture.
What is RMI stub/skeleton layer?
The Stub/Skeleton layer is responsible for intercepting calls made by the client and redirecting these calls to the remote object. This layer is also called as Proxy Layer. Stub and Skeleton are the proxies for client and server. The Stub and Skeleton objects are like an interface between an application and the rest of the RMI System.
What are the goals of RMI?
Following are the goals of RMI − To minimize the complexity of the application. To preserve type safety. Distributed garbage collection. Minimize the difference between working with local and remote objects.
