Websphere FAQ

Clustering is grouping of the servers.Every cluster member must have the same configuration and same version.We can say each cluster member is the clone to one another. Clustering concept is for High ...

Clustering is nothing but the logical grouping of application servers.

By using clustering we can provide the high availability environments for application.

Clustering can be done in 2 types

1. Horizontal clustering
2. Vertical Clustering

If we want to deploy an application in 5.X we need to stop all the cluster members .In 6.X we have a concept called ROLLOUT UPDATE which will make the update on each cluster member separately where we were not needed to stop all the cluster members .

in WAS 5 there was no concept of profiles, but in WebSphere 6 profiles are created under which again servers a created.

Federation is nothing but addition.Federating the node means we have to add the node of the standalone application server to the DMGR profile.

This refers to adding a Node to a Websphere cell.A node is a collection of application server instances. A cell is a collection of nodes.To federate the node you must use the addNode command or a...

When a node is federated to the DMGR a node agent will be formed. To perform any actions like start server and stpop server the DMGR send the request to Node agent and it will send the request to Node.And It will push the configuration changes from the Master repository to the node.

Node Agent is Server which acts as communication between Deployment Manager and Application Profile server which is federated to DMGR

We can see the port numbers in 2 ways: 1. From the console servers--> application Servers ---> select appropriate Application server ---> right hand side under communications we can see the Ports. Se...

you can change the port numbers in serverindex.xml file

it is about the application availability for the users who are using it. We can provide the high availability by installing the application in different cluster members. In case one of the Application...

High availability basically provide fail over to cluster member.In websphere world core group is a set of process that provides High Availability to cluster member.whenever we will create an applicati...

Fix pack: Fix packs are unscheduled releases which consisting of relative few fixes to address significant issues discovered between regularly scheduled maintainable releases.

Hi, Release: --------------- This is the term used by web sphere development and support for a major version of web sphere. The first 2 digits of the product version number identify the re...

To install fix packs We need the following 1. Update installer 2. Appropriate fiX packs for WAS,SDK,HTTP SERVER AND PLUG-IN. STEPS: 1. Stop the server before you apply the fix packs. 2. Use update ...

WEBSEREVER: It will serve only HTTP protocol requests and it will divert the URLs to the application servers. It can serve only static content and is used to display customised error messages. Applic...

Web server: It contain static pages or HTTP images only.

App server: It the user requests to servlets, jsps i.e dynamic content, it also contains container for EJBs

Managed Node: It have a node agent,it can managed Dmgr and federated profile.
Unmanaged Node : It dont have node agent, why because it does not managed Dmgr and profiles.

Managed Node: The node which is managed by Deployment manager is called Managed Node.

Unmanaged Node: The node which is not managed by Deployment Manager is called Unmanaged node.

Cell: A cell is a grouping of nodes into a single administrative domain. Based on the Websphere packages the servers available in each node will vary. Node: A node is nothing but logical grouping of ...

Hi, From the console go to Applications --> Enterprise Applications --> Select the deployed application --> select virtual host under web module properties --> change the virtual host which should be...

Update: It is used to update a full application or a single module or a single file or a part of application or replacing the old file with new file within a server Rollout Update: It is used to sequ...

As the name suggests fix pack is synonym for patch whereas feature pack is like an addon to a software which will provide added functionality.
