What is Middleware? - Middleware News

Middleware is computer software that connects software components or applications. The software consists of a set of services that allow multiple processes running on one or more machines to interact across a network. This technology evolved to provide for interoperability in support of the move to coherent distributed architectures, which are used most often to support and simplify complex, distributed applications. It includes web servers, application servers, and similar tools that support application development and delivery. Middleware is especially integral to modern information technology based on XML, SOAP, Web services, and service-oriented architecture.

Middleware sits "in the middle" between application software working on different operating systems. It is similar to the middle layer of a three-tier single system architecture, except that it is stretched across multiple systems or applications. Examples include database systems, telecommunications software, transaction monitors, and messaging-and-queueing software.

The distinction between operating system and middleware functionality is, to some extent, arbitrary. While core kernel functionality can only be provided by the operating system itself, some functionality previously provided by separately sold middleware is now integrated in operating systems. A typical example is the TCP/IP stack for telecommunications, nowadays included in virtually every operating system.

In simulation technology, middleware is generally used in the context of the high level architecture (HLA) that applies to many distributed simulations. It is a layer of software that lies between the application code and the run-time infrastructure. Middleware generally consists of a library of functions, and enables a number of applications – simulations or federates in HLA terminology – to page these functions from the common library rather than re-create them for each application

    You’d outstanding guidelines there. I did a search about the field and identified that very likely the majority will agree with your web page.

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...

IBM Websphere MQ interview Questions Part 5

MQ Series: - It is an IBM web sphere product which is evolved in 1990’s. MQ series does transportation from one point to other. It is an EAI tool (Middle ware) VERSIONS:-5.0, 5.1, 5.3, 6.0, 7.0(new version). The currently using version is 6.2 Note: – MQ series supports more than 35+ operating systems. It is platform Independent. For every OS we have different MQ series software’s. 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 ...

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...
