Middleware Interview Questions2 - Middleware News

7. What are the different categories of client/Server applications?
Classes of client/server applications: Client/Server applications can be categorized by class,
based on where most of the processing is done. Each class requires different hardware and
software capabilities on the client, the server and the network.
1. Host-Based Processing
2. Client-Based Processing
3. Coopeartive Processing


8. What is meant by Client, Server & Network?
Client : The client hardware is the desktop machine that runs client software. It could be a micro
or a workstation. The client software formulates data request and passes the request to the
network software. This software sends the request to the server, accepts the result from the server
and passes the request back to the client software.
Server : A server is the machine that runs data management software that has been designed for
server functionality. A server has operating system software, data management software and a
portion of the network software.
Network : The network hardware is the cabling, the communication cards and the devices that
link the servers and the clients.

9. Define Application server.
Application Server : Application server, which provides specific application services to an
application. Application servers are the type of middleware, which occupy a large chunk of
computing territory between database servers and end users.

10. What is meant by HTTP and ODBC?
1. ODBC : Open database connectivity is a windows technology that lets a
database client application connect to a external database. To use ODBC,
the database vendor must provide an ODBC driver for data access.
2. HTTP : Hyper Text Transfer Protocol is the underlying protocol used by
the world wide web. HTTP defines how messages are formatted and
transmitted and what action web servers and browsers should take in
response to various commands. HTTP only supports transmission of text.

11. Define Group Server.
Groupware Server : A Groupware server is a software designed to enable users to
collaborate, regardless of location through the internet or a corporate intranet and to work
together in a virtual atmosphere.

12. Define TCP/IP and IPx/SPx.
TCP/IP : Transfer control Protocol and Internet Protocol.

Troubleshooting Java/JMS SSL Configurations - Middleware News

 This document is intended to help diagnose WebSphere MQ V7 Java™ or JMS SSL setup errors. It lists most of the common configuration errors that can cause an SSL connection from a Java/JMS client to a queue manager to fail, and gives the course of action to resolve the problem. In each case the error can be diagnosed by a combination of the error seen in the client log - either a console output, trace file or SystemOut.log file - and the queue manager's error logs. The document is quite long, so the easiest way to find the potential error is to search for one of the errors seen in this list, then filter this list using the error from the opposite end of the channel. All cases here assume that 2-way authentication is being attempted (SSLCAUTH set to REQUIRED on the queue manager's SVRCONN channel). This is the default, and the errors are very similar for 1-way authentication (SSLCAUTH set to OPTIONAL). Symptom Instructions on collecting documentation...

Using telnet to test connectivity between IBM Websphere MQ Client and MQ server - Middleware News

You are having trouble connecting a WebSphere MQ client to a MQ server, receiving errors that you can not connect to the MQ queue manager. One of the first things to determine is if the two machines can communicate, and using the telnet tool is one way to accomplish it. Symptom Receiving errors which state that a queue manager is not found or not available. Connection errors. For example: AMQ9213, AMQ9524, AMQ9202 or AMQ9508 or MQRC =2059 0x0000080b MQRC_Q_MGR_NOT_AVAILABLE. Please note, this is by no means an exclusive list of errors related to this type a problem but just a sample of some of the more common error messages and codes that might occur. Cause One possible cause is that the two machines can not communicate. May be the IP address or hostname was not properly specified by the MQ client. The port number might be incorrect. A queue manager is not running at the desired host. The queue manager could be running, but the corresponding listener is not runnin...

But the functionality of MQ series Default path for installing MQ series is:- C: programfiles\BM\clipse\SDK30 C: programfiles\IBM\WebsphereMQ After installation it will create a group and user. Some middleware technologies are Tibco, SAP XI. MQ series deals with two things, they are OBJECTS, SERVICES. In OBJECTS we have • QUEUES • CHANNELS • PROCESS • AUTHENTICATION • QUERY MANAGER. In SERVICES we have LISTENERS. Objects: – objects are used to handle the transactions with the help of services. QUEUE MANAGER maintains all the objects and services. QUEUE: – it is a database structure ...
