Has anyone done this ???
Whenever you deploy the new version of the application we stop the application, uninstall the existing version & install the new version.
Now, our problem is we dont want to bring down the server.
We have a websphere ND server clustered environment. In the current environment we have one deployment manager & multiple appservers are federated to this. We dont deploy the application on individual servers, instead we deploy the application on Deployment Manager. The DMgr transparently deploys on the individual servers.
For doing this we need to stop the application, uninstall it. This will uninstall from all the servers. so, we need an outage until new version is installed.
we want to avoid this, we want to upgrade the servers one by one ....so, that our system will be running 24/7.
can you think of some solution.
Any help will be highly appreciated.
thanks & regards,
