Websphere Interview Questions and Answers for freshers and experienced pdf (Part2)

11) Explain about the network deployment feature present in WAS?
Managing singletons will be a thing of the past and it also provides hot recovery of singletons which makes you forget about your GC collected singletons. Transaction logs can stored on a shared file system. For clustering run time operations deployment manager`s role was eliminated. J2EE failover support and cell configuration support is also present.

12) Explain about IBM web sphere integration developer?
Web sphere integration developer provides an IDE to build applications based on service oriented architecture. Web sphere process server and web sphere ESB were built with WID. WID was built with RAD Eclipse based technology.

13) Explain about compute Grid?
Compute grid is also known as Web sphere batch. Web sphere extended deployment offers a Java batch processing system called as Compute Grid. This forms an additional feature to Web sphere network environment. Various features are provided which help a developer to create, manage and execute batch jobs. Job scheduler, xJCL, batch container and batch programming controller.

14) Explain about web sphere MQ Real time transport?
This feature is very useful in instant messaging across different clients through intranet and internet. This supports high volume and high performance across different clients. It uses the concept of light weight transport which is again based on IP rather than the queue process.

15) Explain about Web sphere MQ JMS Provider?
Web sphere MQ and Web Sphere Business integration manager Broker are very useful in providing Java messaging services to wide range of clients (publisher –subscribe, point to point). Java classes are chiefly responsible for translating the API calls to API`s defined by web sphere. It is very useful to have knowledge of Web sphere MQ for proper configuration.

16) Explain the attribute CHANNEL in web sphere MQ?
CHANNEL specifies the name of the server connection channel. Generally this is Web Sphere MQ network abstraction. The default standard used by CHANNEL is SVRCONN which is the server connection channel. This server is generally used to communicate to the queue manager by the client.

17) Is the naming of connection factory independent of the name specified by JMS client?
Yes, the naming of connection factory is independent of the name specified by JMS client. This is made possible by WAS (Web sphere application server) with its resource references. It isolates the application from object names. This feature is important because it gives us the flexibility to change the administered object without changing the JMS client code.

18) How do you specify a jar file to be used by the application, consider that you have many jar files in your system?

19) What is a managed node?
Node with NodeAgent

20) What is a managed webserver?
Remote webserver access through local (dmgr/cell)
