hi

major differnce is in V5.0, Base and ND have seperate installations. Also to create another stand alone node we used %was_home%binwsinstance and created anoher instance.

in V6.0, Base (AppServer), ND and another Stand Alone or Federated Nodes are considered as PROFILES. After u install Base (Appserver), to install ND u dont need another CD or installation files. U can create ND and more nodes in %was_home%binProfileCreator and using either pctwindows.exe or pct.jar u can install more nodes or ND.

this is fast, takes less space on ur hard drive and u can create more nodes easliy and faster.

Keep an eye on the default port numbers, they r different. Other than that in resources you also have WEB SERVER.

Hope this helps.

When you install, update, or delete an application, the updates are automatically

distributed to all members in the cluster. In WebSphere Application Server V5, if

you updated an application on a cluster, you had to stop the application on every

server in the cluster, install the update, and then restart the server. With

WebSphere Application Server V6, the Rollout Update option allows you to

update and restart the application servers on each node, one node at a time.

This provides continuous availability of the application.
