Ibm Websphere Administration Placement Papers - Ibm Websphere Administration Interview Questions and Answers updated on 14.Jun.2024

The following are the definitions -  

  1. Node - node is basically the grouping of the processing of the server. This grouping is done logically and is well maintained by the Websphere tool. It also helps in controlling the operations and data configuration.  
  2. Node agent - each node consists of an agent which works side by side the deployment manager and hence the administration process is managed by it. In short, the node agent acts as the mediator if both deployment manager and notes.  
  3. Node group - This refers to the grouping of various nodes and has the same capability of that of nodes.  

Websphere MQ programming APIs include

  • JMS  known as Java Message Service
  • AMI known as Application Messaging Interface
  • MQI known as Message Queue Interface

Web logic includes various attributes which are default tractions like for example supports. However, WebSphere doesn't include any such type of default tractions. The focus on creativity and the integration are mainly done by WebSphere. Web services are also maintained peppy by it. Hence, the performance by WebSphere is much nicer and better than that of web logic. In fact, integration and the management of tractions are also better than web logic. 

The WebSphere application server or also known as the WAS provided by IBM is considered to be able to store all Thebes data and information regarding the configuration process.  It stores them in the repository provided by nodes which are known as the Master Repository. In order for the entire configuration to be stored or simply send to the server of the respective nodes while using DMGR process, the nodes must be synced properly. It is basically communication between the master repository and the local repository and can be done only in one way.

Ripple start is the process used for restarting the cluster of WebSphere administration server. The JVM is at first stopped by it and then again started with the help of Ripple Start. However, only one JVM can be restarted at a single time. Like for example, if in a cluster a total of 5 JVMs are present and if Ripple Start is used, it will first close the first JVM and then again restart it. In this way, it will be consecutively closing and restarting one JVM after another.

Virtual hosts are considered to be the ones which consist of various kinds of URLs like FQDN and IP. These are all present in the single application. The configuration of the same is also done with the WebSphere application server. The application must be included in an URL and this is known as the virtual host. Hence, this application remains associated with its URL in the virtual host.

In WebSphere, deployments are extended due to the purpose of increasing the service quality. The gets increased with the help of optimization of the IT resources.

It works in three main areas as follows -  

  1. Websphere extreme scale  
  2. Compute Grid 
  3. Websphere virtual enterprise  

Mostly there are 5 WebSphere Componets: Generic servers, WAS, Web Server, and Data Server.

Communication between users with the help of messages is done with the help of WebSphere MQ. This is basically a type of application program. Mainly commercial communication or messaging is done by WebSphere MQ.

The communication through application by this can be done in two ways:

  1. Fire and Forget
  2. Request and Response.

The WebSphere application gets clustered with the help of the server's plugin components routes which allows the cluster to get requested. It routes all the requests to a particular member of the cluster if one of them fails to work properly due to the failure of the connection. That particular member is marked and the routing the requests continue till the availability of the original cluster work.

  • Web-sphere application server contacts the registry when users.
  • Maps the certificate information to a userid.
  • Checks for the user’s password.
  • Obtains any group information.
  • Converts userid to registry unique id.

  • Node can be considered as an process alignment which are related for the server and are being managed by ibm WebSphere which share common setup.
  • Nodeagent: Every node is equipped with an agent which acts as its assistant and is responsible for the administration tasks.
  • Clustering techniques in both of these are generally same in a number of aspects. 

The programming APIs of WebSphere MQ are as follows -  

  1. Application Messaging Interface (AMI)  
  2. Message Queue Interface (MQI)  
  3. Java Message Service (JMS) 

The default messaging provider provides functions which are well published and also subscribed. For trportation, it uses the bus of integration of services. These service integration destinations also correspond to various JMS connection destinations and factories.

Weblogic maintains attributes in order to support default traction, whereas Websphere would not have such kind of default tractional attributes.

Websphere is more focused on integration,connectivity, and web services. It performs better in implementation of J2EE, and in extensive integration and management of tractions as compared to Weblogic.

WebSphere has the following list of features -  

  • The applications or the servlets are well supported by WebSphere and this runs with the help of HTTP function.  
  • WebSphere supports various HTTP servers like the IBM HTTP server, MS IIS, and Netscape iPlanet server etc.  
  • It also supports Workload Management and the component model if EJB.  
  • WebSphere is also known to support the server pages of Java and XML etc.

  • Support to the container functionality 
  • Support to HTML pages 
  • Supports the HTTP servers

WebSphere MQ is a program that allows us to communicate with each other using queues&messages. Communication in this form is known as commercial messaging.

There are two methods ofcommunication amongst the application:

  • Request/Response and 
  • Fire & Forget.

WebSphere is developed by IBM. This is a tool is designed with the help of Java. IBM has developed this tool in order to create and manage websites. These websites are mainly used for the purpose of business and business functions which are helpful in the field of e-commerce. The data gets integrated carefully across various systems and operating applications by WebSphere. WebSphere application server that is WAS is the central tool for WebSphere.

For the communication of the data which are encrypted, between various processes, a certain protocol is used and this is known as SSL. 

  • It is basically an important set that contain all the Java Classes which are useful
  • All the JMS applications are managed through it
  • For clients, only a part of it is accessible rather than whole.
  • Users need to check the efficiency again and again to make sure of a constant output.

The cluster in the WebSphere is partitioned dynamically and only one cluster can run at a specific allotted time. This is how asymmetrical clustering works. A particular task can be allotted to a particular cluster.

Applications needs minimum amount of memory to reach the stable state,which occurs when the heap is no longer growing consistently. If the JVM is configured with a maximum heap, which is too small, it will never permit the JVM to reach the stable state, which will make allocation failures and the JVM will initiate to throw OutOfMemoryError.

It is basically a powerful tool that is actually an initiative of IBM. The primary purpose is to simply create and manage the websites in a reliable manner. When it comes to building the web applications that are scalable, this tool can simply be used. The good thing is almost all the functional related to a business can easily be supported by it. Even if the data belongs to Operating Systems which are different in nature, it is possible to combine the same with the help of this tool.

Extended deployment in WebSphere provides advantageous qualities of service with optimizingfeatures.

It covers three areas:

  • WebSphere eXtreme Scale
  • WebSphere Virtual Enterprise
  • Compute Grid

  • In this, all the logics which are related to a business are divided into simple panels for better understanding
  • It cannot stand equal to a stateless server due to obvious reasons. Actually, it acts opposite to the same and always make sure of functionality.
  • The Asymmetric clustering in the architecture cannot be considered similar so the stateless server. In fact, it is totally opposite to the same. Generally in the stateless server, the applications are frequently repeated. This can sometime help in boosting the efficiency. 
  • All the nodes show outcomes due to cluster implantation through the cache which is local in most of the cases. Actually, this also contribute in making sure of efficiency under every situation.

The connecting pool is basically the cache of various connections of the database and is maintained in such a way that can be used again the near future. Such requests for database caching are very frequent and common in WebSphere. However, when all the connections get occupied then a whole new connection is made and gets automatically added to the pool. 

General, two types of the cluster are done. The horizontal cluster refers to the cluster which can be done between a huge number of multiple nodes and all the servers found in the cell. On the other hand, the vertical cluster is mainly done between the members I'd the same bode and server. 

The MQ client often has a particular name which distinguishes it from any other client and this is known as SSLPEER. This gets linked to the QueueManager and is used for the identification of clients.

QueueManager is an important element of WebSphere MQ. It is responsible for routing &storing messages to all other queue manager within the MQ, and communicates with the outside world too.

The applications in WebSphere get deployed in three ways.

These are as follows - 

Hot deployment - hot deployment includes the copying of the application file simply to the application directory. However, this process is not recommended for production purposes and is suitable for non-production purposes and environment.  

Scripts - By this, application deployment can be done by developing ant tasks or by developing wsadmin scripts.

DMGR - simply by clicking new application option from the Application bar, the deployment can be done by DMGR.

WebSphere’s server plugin element routes all requests to WebSphere’sweb containers. Whenever there is any communication failure within a specific member of cluster, it mark’s the member down & starts routing all the requests to other clusters untill the primary is available.

The dynamic cache is the one which helps in the improvement of the performance produced by the caching of the various output of applications. The objects to be cached are intercepted within the cells with the help of the Dynamic cache service. Then the content is provided by it or is stored. 

WebSphere edge is basically the components of a set if server application which is used for the improving the performance and the function of systems which are based on the web. This WebSphere edge is considered to be the part of IBM WebSphere product tool.

It has the following four components -  

  • It Dispatches Network  
  • Distributed contents  
  • Proxy is well cached

WebSphere Edge is a group of web application server components which is supposed to improve the productivity of web-based information systems, and is an integral part of IBM WebSphere product suite.

It comprises of 4 basic components:

  1. Caching Proxy
  2. Network Dispatcher
  3. Application Edge Service
  4. Content Distribution

Edge is configured for high availability with a backup of Edge failover server which makes over sessions in case the primary Edge server fails.

The business owner can now execute complex operation based on “what if “scenarios, followed by analyzing and creating reports from the simulated results to detect the problem areas in the processes. Advanced Edition of WebSphere offers all the capabilities of the Initial Edition apart from Advanced Edition which also provides “jump-start” to any development of application by enabling more focused users, like IT architects, to export the models to UML, or other FDL models, for further development.

WebSphere Business Edition Version 5.1 is a cost effective option for businesspersons looking for simple model, document, and print their business tractions &processes.

Generally, the proxy is cached in the forward direction and are hence configured in this particular direction. On request of a particular content by users, the WebSphere edge first caches it and then sends it according to their requests. Page fragments of applications are also cached by WebSphere edge and when this process becomes slow then it gets optimized by the Websphere edge server.
