The old Java developer's pass to enduringness with JDO!
Master JDO, the insight profession for persistenting Java objects!
Java Data Objects (JDO) streamlines utilization by providing Java-centric mechanisms for making objects persistent, and accepted APIs for conjunctive covering cipher with inexplicit continual datastores.

 

Core Java Data Objects is the definitive, broad pass to JDO enduringness for every old Java developer.

Using graphic cipher examples, this book's proficient authors counterbalance creating, reading, updating, and deleting continual objects; goal lifecycles and land transitions; JDO classes and APIs; queries, architecture, security, and such more. They exhibit how to combine JDO with EJB, JTA, JCA, and another J2EE technologies; and inform prizewinning practices for using JDO in both standalone programs and J2EE components.

 

If you poverty to pay more instance finding playing problems and inferior instance bedevilment most persistence, you requirement JDO. And you requirement the digit aggregation that'll support you attain the most of JDO: Core Java Data Objects.

Asynchronous Vs. Synchronous Communications

Synchronous (One thread):   1 thread -> |<---A---->||<----B---------->||<------C----->| Synchronous (multi-threaded):   thread A -> |<---A---->| \ thread B ------------> ->|<----B---------->| \ thread C ----------------------------------> ->|<------C----->|

WebSphere MQ Interview Questions

What is MQ and what does it do? Ans. MQ stands for MESSAGE QUEUEING. WebSphere MQ allows application programs to use message queuing to participate in message-driven processing. Application programs can communicate across different platforms by using the appropriate message queuing software products. What is Message driven process? Ans . When messages arrive on a queue, they can automatically start an application using triggering. If necessary, the applications can be stopped when the message (or messages) have been processed. What are advantages of the MQ? Ans. 1. Integration. 2. Asynchrony 3. Assured Delivery 4. Scalability. How does it support the Integration? Ans. Because the MQ is independent of the Operating System you use i.e. it may be Windows, Solaris,AIX.It is independent of the protocol (i.e. TCP/IP, LU6.2, SNA, NetBIOS, UDP).It is not required that both the sender and receiver should be running on the same platform What is Asynchrony? Ans. With messag...

Advantages & Disadvantages of Synchronous / Asynchronous Communications?

  Asynchronous Communication Advantages: Requests need not be targeted to specific server. Service need not be available when request is made. No blocking, so resources could be freed.  Could use connectionless protocol Disadvantages: Response times are unpredictable. Error handling usually more complex.  Usually requires connection-oriented protocol.  Harder to design apps Synchronous Communication Advantages: Easy to program Outcome is known immediately  Error recovery easier (usually)  Better real-time response (usually) Disadvantages: Service must be up and ready. Requestor blocks, held resources are “tied up”.  Usually requires connection-oriented protocol
