Ibm Was Administration Placement Papers - Ibm Was Administration Interview Questions and Answers updated on 19.May.2024

Multiple stand alone application servers can be managed by using a job manager through administrator agents.

Websphere is focused more on connectivity, integration, and web services.  It has better performance, rich implementation of J2EE, more extensive integration and traction management compare to Weblogic.

Weblogic has default traction attributes as supports, while websphere does not have such type of the default traction attribute.

The administrator can find the binding information in the deployment descriptor.

Application scoped resources can be removed from an enhanced EAR file by removing META—INF/ibmconfig directory.

Yes, you can, as long as system i box can be accessed through network.

Yes, you can, during profile creation wizard.

WAS (WebServer Application Server) stores all the configuration in one central location referred as “Master Repository”. The sync ensures the configuration in both local and master repositories are same and in sync.

No, SIBus messaging engine cannot be managed by fine-grained administration.

No, you can’t as there is no GUI interface for version 5.

In asymmetric clustering, the partition can be defined dynamically and runs on a single cluster at a time. The task which is particular to an appropriate cluster can be routed to that cluster.  Usually, clustering is used by banks.

No, migration wizard only provides minimal function and it does not enable any services by default.

No, you can’t as this file is locked by application server process.

Including special characters in your local host name may cause problem in profile creation.

No, it will not work as WAS 8 should be installed after those earlier versions.

If the administrator is implementing an application which requires a connection to the databasethen he needs to create a JDBC provider.

Application server can be administered using admin console and wsadmin.

WebSphere MQ is an application program that allows you to communicate with each other using messages and queues.  This form of communication is referred as commercial messaging.  There are two methods for application to communicate, Request/Response and Fire & Forget.

A WebSphere’s web server plugin component routes requests to WebSphere cluster web containers.   If there is a communication failure with a particular cluster member, it will mark that member down and start routing all requests to the remaining cluster member till the original is available.

QueueManager is the important component of WebSphere MQ.  It is accountable for storing and routing messages to other queue manager within MQ, and it also communicate with the outside world.

Web-sphere application server contact the registry for user when users

  1. Checks the users password.
  2. Maps certificate information to a userid.
  3. Converts userid to registry uniqueid.
  4. Obtains group information.

Flexible management topology can be an alternative to the network deployment cell.

Caching server provides functionality like

  1. Reverse proxy and content based routing.
  2. Integration with servlet caching and dynamic content caching.

Websphere MQ programming APIs include

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

No, you can’t. You have to install it using QShell command line.

WAR or EAR files are required to deploy an application into Web-sphere.

Class loader policy, JAAS authentication aliases and virtual host information can enhance EARs support apart from EARs support and shared libraries.

  1. Node : It is a logical grouping of server processes maintained by WebSphere and that share common configuration and operational control.
  2. Nodeagent :  Each node has a nodeagent that works along with the deployment manager to manage administration processes. It acts as a mediator between the node and deployment manager.
  3. Node Group : A node group is a grouping of nodes within a cell that have same capabilities.

A cell is referred as a grouping of nodes into a single administrative domain. A cell can have multiple nodes which are all managed from a single point.

The extended deployment in WebSphere leverages enhanced qualities of service with features optimizing IT resources. It sp three areas

  1. WebSphere Virtual Enterprise.
  2. WebSphere eXtreme Scale.
  3. Compute Grid.

Web-sphere is a tool based on Java and developed by IBM, to manage and create websites.  Web-sphere is often used to build interactive web-oriented applications that support business functions required for e-commerce, it integrates all the data across different operating system and applications.

Important components of Web-Sphere are

  1. WebSphere Application Server or WAS: It connects the website users with Java servlets.
  2. Data–Server: For data persistence.
  3. Web–server: It provides the service of HTTP.

The administrator can assign security permissions to actual users by mapping application roles to users or groups in the WebSphere user registry.

In Websphere application can be deployed in three ways

  1. Copy files directly to deploy application folder in websphere.
  2. Use websphere specific ant tasks create automated scripts for deploying application.
  3. Via administration console.

The WebSphere edge server is used to enhance the performance of web based systems.  It can be used as a proxy server.  There are basically four components in the web sphere they are caching proxy, content distribution, network dispatcher and application server at the edge.

SSLPEER is a string usually distinguished name of MQ client, which links to QueueManager securely using QueueManager.  This is a mechanism used to identify client.

Some of the features available in Web-sphere includes

  1. It supports the servlet/JSP container functionality that runs on top of HTTP.
  2. It supports HTTP servers as IBM HTTP server, Netscape iPlanet server, and MS IIS.
  3. It supports Java Server Pages, HTML pages, Servlets and XML.
  4. It supports EJB component model and Workload Management.

Connecting pool is a cache of database connections maintained so that connection can be re-used when future requests to the database are required. If all the connections are occupied, a new connection is created and is added to the pool.

Administrator must create the new profile with a services enabled before starting the wizard, and then point to that profile during the migration wizard.

Servlets can be protected by method permissions.

  1. wsadmin script,
  2. -verbose:gc commandline attribute and
  3. -Xoptionsfile command line option.

No, you can’t but you can delete a profile by manageprofiles command facility.

Here is a list of new capabilities:

  1. Asingle installation technology for installing and uninstalling product
  2. Updating and rolling back fixpacks and iFixes
  3. Installing and uninstalling feature packs
  4. GUIinterface to perform individual operations; response files can be recorded either from the GUI or created by specifying the appropriate XML file for silent installation purposes
  5. Silent mode support for invoking multiple operations.

  1. A caching proxy can be configured in forward direction or as a proxy. When user requests the content, it is cached by the edge before sending or following to the query.
  2. Page fragments arising from Servlets or JSP are cached by Edge, and the Caching process becomes Slow.
  3. Performance and scalability can be optimized by edge.
