Apache Activemq Interview Questions with Answers

Question: 1. What Is Activemq?

Answer:

Apache ActiveMQ is an open source message broker written in Java together with a complete Java Message Service (JMS) consumer. It presents “Enterprise Features” which in this situation method fostering the communique from more than one patron or server.

Question: 2. What Is Use Of Activemq Instead Of Other Options Like Database?

Answer:

Activemq is used to reliably speak among two allotted processes. It can save messages in a database to communicate among to strategies, however as quickly as the message is obtained you would ought to delete the message. That approach a row insert and delete for each message. When you try and scale that up speaking hundreds of messages consistent with 2d, databases generally tend to fall over.
Message orientated middleware like ActiveMQ then again are build to deal with the ones use cases. They asume that messages in a healthful system might be deleted right away and might do optimizations to keep away from the overhead. It can also push messages to consumers instead of a consumer having to ballot  for brand new message through doing a SQL question. This in addition reduces the latency worried in processing new messages being sent into the system.
Apache Cassandra Interview Questions
Question three. What Is Jms?

Answer:

Java Message Service (JMS) is an application program interface (API) from Sun Microsystems that supports the formal verbal exchange known as messaging between computers in a community. Sun’s JMS gives a common interface to conventional messaging protocols and also to important messaging offerings in aid of Java packages. ActiveMQ is based on JMS.

Question: 4. How Does Activemq Compare To Amqp ?

Answer:

AMQP stands for the Advanced Message Queue Protocol and is a specification for how messaging clients and agents can interoperate. AMQP is a specification of a wire-degree protocol for purchaser to message broking verbal exchange. It isn’t always a messaging system like ActiveMQ, however only a messaging protocol.

ActiveMQ now implements AMQP 1.Zero

ActiveMQ additionally supports other open twine protocols:

    OpenWire, a quick binary layout
    Stomp, a simple and without difficulty implemented textual content based-protocol
    MQTT, a compact binary layout for confined gadgets on an unreliable community

Through these protocols, ActiveMQ can aid clients in C, C++, C#, Ruby, Python, Perl, PHP, Pike and so on. AMQP is most similar to OpenWire, because both OpenWire and AMQP are designed for excessive performance messaging, through a binary (in place of text-primarily based) layout. As a textual content-based totally format, STOMP is much easier to enforce, but offers incredibly slower performance.

Question 10. How Does Openwire Compare To Stomp ?

Answer:

OpenWire is the local protocol that Apache ActiveMQ makes use of. It is designed for overall performance and size at the wire – sacrificing some ease of implementation with higher performance and decreased community bandwidth as a concern. OpenWire turned into first launched in Apache ActiveMQ four.Zero.

Stomp is a less complicated textual content based totally protocol that’s designed to be quite simple to put in force in some hours in any language or platform (e.G. You may use a telnet consumer to communicate via Stomp). A Stomp customer isn’t always going to be as green as an consumer that uses
OpenWire, however it tons simpler so you can commonly be up and going for walks with it a good deal quicker.

Apache Pig Tutorial
Question 11. How Can I Monitor The Connection With The Broker ?

You can reveal the status of the connection with the dealer thru the addTransportListener() technique at the ActiveMQConnection.

This method takes a TransportListener that is notified as the relationship is hooked up & dropped. It also allows you to work with the Failover Transport yet nevertheless realize the status of the relationship.

Apache Ant Interview Questions
Question 12. How Does Activemq Compare To Spread Toolkit ?

Answer:

Spread Toolkit is a C++ library for messaging and only has partial support for JMS. It does not help durable messaging, transactions, XA or full JMS 1.1. It is likewise dependent on a local code Spread daemon running on the system.

Apache ActiveMQ however is the JMS company utilized in Apache Geronimo and is J2EE 1.Four licensed in Geronimo and is one hundred% pure Java. ActiveMQ supports brief and durable messaging, transactions, XA, J2EE 1.4, JMS 1.1, JCA 1.5 as well as hundreds of different capabilities like Message Groups and Clustering.

CoffeeScript Interview Questions
Question 10. How Do I Learn Applescript?

Answer:

Probably the excellent approach to gaining knowledge of AppleScript is to shop for one of the available AppleScript books or the Scripting Kit and work thru the scripts within the book. Constantly playing around with AppleScript also enables. Because Apple event and object version assist in third birthday party applications isn’t regular, you’ll quick discover that what works in a single program may not paintings in every other. Experience is the high-quality teacher in those instances.
Another street for studying how to script is to observe the scripts that others have written. Look at the instance scripts which can be furnished with the Scripting Kit. You also can watch the development of Apple events within the Log window (AppleScript 1.1) to learn greater about how scripts paintings. If you are using one of the 0.33 party script editors (Scripter or Script Debugger), you could watch the variables as they trade.
If you’re operating with an application that is recordable, you can report moves in the software after which study the scripts that it produces. Since the application is “writing” the script, you may get a better concept of the commands that it is aware and how they ought to be scripted.
Of course, you could usually be part of the MACSCRPT mailing list, study all the messages, and run all of the scripts that are posted and mentioned. This is a bit more interactive than analyzing a e-book.
