These are very Basic WebSphere Interview Questions and Answers for freshers and experienced both.
Q1: Explain what is PowerShell?
A1: Power shell is an extendable command shell and a scripting language for Windows.
Q1: What is Ripplestart?
A1: Ripplestart is to restart the WAS cluster. It first stops the JVM and then starts it. By doing ripplestart you ensure only one JVM is down at one time hence no downtime to the applications.
Ex: you have 5 JVMs in a cluster and when you do ripplestart it will stop JVM1 and start JVM1 before stopping other JVM in a cluster.
Q2: What would you do when JVM is consuming 100% CPU & Memory on a server?
A2: First of all, identify which JVM has high utilization. Take a thread dump of identified JVM for investigation and restart the JVM as a workaround to cool down the CPU/Memory.
Q3: What is node sync?
A3: IBM WAS stores the entire configuration in a central repository called “Master repository,” and every node will have the local repository.
When you make any changes to the node through DMGR, you must sync it, so configuration is pushed to respective node’s server.
Sync always happens from master to local repository, so it’s one-way communication.
Q4: Can application run without any issue if DMGR is down?
A4: Yes, DMGR down doesn’t impact existing running application. However, if you need to make any changes or deployment through DMGR, then that would be affected.
Q5: How to deploy an application in WebSphere?
A5: There are three possible ways to deploy.
- Hot deployment – copy the application file into the application directory. This is good for the non-production environment and not recommended for production.
- DMGR – You can deploy an application through DMGR by going to Applications >> New application
- Scripts – You can develop wsadmin scripts or ant tasks for application deployment.
Q6: What file types you can deploy into WebSphere?
A6: You can deploy WAR, EAR, JAR or SAR module through DMGR console or scriptings.
Q7: What is a virtual host?
A7: Virtual host contains multiple URLs (IP or FQDN based) on a single application and configuration is done through WAS administrative console.
In order to allow an application to be accessible on particular URL, you must have this URL in a virtual host and associated with the application.
Q8: How would you deal with slow application complaint from clients?
A8: Slowness could cause due to various reasons, and it’s essential to identify if it’s from WebSphere or some other components. To isolate, you can check the following.
- Is this slowness for all the users?
- Is entire application slow or just particular functionality?
- How about accessing JVM URL (bypassing Web server) directly?
If the slowness is found in JVM, then you can take the dump and check the logs to find out the cause. It would be worth checking if there were any release and slowness is just after that.
Q9: How to take WAS configuration backup without stopping the DMGR?
A9: Go to DMGR profile and bin folder
Execute ./backupConfig.sh -nostop to take a backup
Q10: What’s the default WAS port?
A10: The default port for HTTP is 9080 and HTTPS 9443. Checkout default port page for more.
Q11: What are the WebSphere editions available?
A11:
- WAS – Network Deployment
- WAS – Developers
- WAS – z/OS
- WAS – Hypervisor
- WAS – Express
- WAS – Base
- WAS – Liberty core
Q12: Mention what is asymmetric clustering in Web-sphere?
A12: 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.
Q13: Explain what is node, node agent and node groups?
A13:
- Node:It is a logical grouping of server processes maintained by WebSphere and that share common configuration and operational control
- 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
- Node Group:A node group is a grouping of nodes within a cell that have same capabilities
Q14: Explain what is a cell in WebSphere?
A14: 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.
Q15: Mention what are the default ports you use to use WebSphere Application Sphere?
A15: The default ports you use are HTTP: 9080 and HTTP: 9443
Q16: Mention when does WebSphere Application server contact the registry for user information?
A16: Web-sphere application server contact the registry for user when users
- Checks the users password
- Maps certificate information to a userid
- Converts userid to registry uniqueid
- Obtains group information
Q17: Explain what is WebSphere is MQ?
A17: 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.
Q18: Explain what is QueueManager in IBM Websphere MQ?
A18: 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.
Q19: Explain what is SSLPEER in IBM Websphere MQ?
A19: 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.
Q20: Explain what is extended deployment in WebSphere?
A20: The extended deployment in WebSphere leverages enhanced qualities of service with features optimizing IT resources. It spans three areas
- WebSphere Virtual Enterprise
- WebSphere eXtreme Scale
- Compute Grid
Q21: Explain About Caching Proxy Of Ibm Web Sphere Edge Sphere?
A21: A caching proxy can be configured in forward direction or as a proxy. Content requested by the user is cached by edge before sending or adhering to the query. Page fragments arising from JSP or servlets are cached by Edge and the caching process is slow. Performance and scalability of J2EE applications can be increased by edge.
Q22: Explain About The Network Deployment Feature Present In Was?
A22: Managing singletons will be a thing of the past and it also provides hot recovery of singletons which makes you forget about your GC collected singletons. Transaction logs can stored on a shared file system. For clustering run time operations deployment manager`s role was eliminated. J2EE failover support and cell configuration support is also present.
Q23: Explain About Ibm Web Sphere Integration Developer?
A23: Web sphere integration developer provides an IDE to build applications based on service oriented architecture. Web sphere process server and web sphere ESB were built with WID. WID was built with RAD Eclipse based technology.

This forms an additional feature to Web sphere network environment. Various features are provided which help a developer to create, manage and execute batch jobs. Job scheduler, xJCL, batch container and batch programming controller.
Q25: Explain About Web Sphere Mq Real Time Transport?
A25: This feature is very useful in instant messaging across different clients through intranet and internet. This supports high volume and high performance across different clients. It uses the concept of light weight transport which is again based on IP rather than the queue process.
Q26: Explain About Web Sphere Mq Jms Provider?
A26: Web sphere MQ and Web Sphere Business integration manager Broker are very useful in providing Java messaging services to wide range of clients (publisher –subscribe, point to point). Java classes are chiefly responsible for translating the API calls to API`s defined by web sphere. It is very useful to have knowledge of Web sphere MQ for proper configuration.
Q27: Explain The Attribute Channel In Web Sphere Mq?
A27: CHANNEL specifies the name of the server connection channel. Generally this is Web Sphere MQ network abstraction. The default standard used by CHANNEL is SVRCONN which is the server connection channel. This server is generally used to communicate to the queue manager by the client.
Q28: Is The Naming Of Connection Factory Independent Of The Name Specified By Jms Client?
A28: Yes, the naming of connection factory is independent of the name specified by JMS client. This is made possible by WAS (Web sphere application server) with its resource references. It isolates the application from object names. This feature is important because it gives us the flexibility to change the administered object without changing the JMS client code.
