An overview on the IBM Websphere architechture
What is Websphere? Websphere is a collection of Java- based tools powered by IBM which allows its consumers to manage and create complicated corporate websites, both large and small scaled and connect it through java based softwares, applications or servlets(programs that on the servers rather than computers). It also supports open standard interfaces such as COBRA and JDBC. It supports OS/2, Windows NT, OS/360, Solaris and AIX operating systems. A Websphere architecture contain one or more computer setup, which are referred to as NODES terms of websphere. Node exists within a websphere cell, which has one node and on that node all softwares are installed. Similarly, the software components are distributed by the multiple nodes.
Websphere application server – Express architecture
The websphere architecture application server- express consists of its these main components
The Websphere Plug-ins enable to communicate the web server to request for dynamic content, like servlets, directly to the server of application. The plus-ins determine whether a request is going to be handled by the application server or web server by the help of a configuration file.
HTTp server receives requests for the components of server – side, like javaServer pages ans servlets and then it passes the commands or requests to WebSphere application server- express through websphere plug-ins. It supports servers like:- iseries IBM HTTP server and Lotus Domino HTTP server.
The Websphere application server – subsystem express. QASE5, contains the tasks that are supposed to rum in the QASE5 subsystem, our application may also use other jobs running in other different subsystem.
The runtime environment for server- side Java components(like Javaserver pages and servlets) are provided by the application server. The application server consists of the given below components of architecture:
It runs within the application server and is used to handle all the requests for javaServer pages, servlets files, and the web application which are contained by them.
A strong security mechanism and infrastructure is provided by the websphere Application server- express, to protect the administrative and sensitive application resources and to address end-to- end enterprise security authentication and access control, directly on confidentiality, privacy and data integrity.
To provide access to java components within a distributed network, Java Naming and Directory Interface(JNDI) is used. It also provides the implementation of the JNDI service so that one can bind the websphere- express resources to JNDI names.
MQ series version 7.0: A jump over the hurdles of Websphere
WebSphere MQ v7.0 is going to revolutionize the market- leading message system SOA with latest releases on Z/OS for IBM system z and for distributed platforms.
- Performance enhanced for publish-and-subscribe and JMS
- Enhanced MQ explorer
- Supports JMS tightly integrated into the runtime and environment of configuration.
- For clients increasing resilience and throughput, enhancement redefines.
- To connect to websphere MQ queues and topics, it contains supported bridge for HTTP enabling AJAX applications.
Thus, Websphere Application server provides intelligent management, efficiency and flexibility that an cost- effective and versatile business requires.
