Deploying a WAR to a cluster issue

Question

Hi,
My question is that, in cluster environment after a WAR file is deployed, I use iAS Admin tool to locate the WAR file. Then I highlight the specific servlet and click on the "Servlet Component Properties" button. A dialog box popups that list out all registered server (in cluster environment) with this servlet. Is there a quick way so that going to each WAR and registering each servlet can be avoided?
The reason I ask this is because everytime I deploy a WAR I first remove it before deploying it. So the
registry should be clean.
What I found is that after the a deployment of WAR1 to a iAS, say iAS1, I can see in Admin tool that the servlet within WAR1 are registered with the IP of iAS1. Ok, now I deploy the same WAR to iAS2. I go into Admin tool again and found that the WAR is now registered with the IP of iAS2, the IP for iAS1 was overwritten. What I have to do is MANUALLY add IP of iAS1 back and click "Apply" to save the change. If this action have to be done individually then it'll take ages to finish the change for my 100 more servlets, especailly when a clean deployment is required (which is what I have to do very soon).
Any idea to avoid the tedious work? I am using iAS6 SP2. Thanks.

Hi,
In my knowledge there was no such issue with sp2 related to your problem. Please check that your cluster is working fine by first testing the cluster Servlet example bundled with iAS. Please ensure that your cluster if properly configured (iasconfig name is same with a common LDAP). Also it is a feature of iAS that if you have deployed an application on all the servers of a cluster and after that you want to disable/undeploy it, you just need to undeploy it on any of the servers. It will remove the common data from the registry and make the app disable for other servers.
You don't have to undeploy the app before redeploying it again, as while redeploying, it will overwrite the previous registry contents (only if you do not change module names and GUIDs otherwise it is as good as a new different application).
Please feel free to ask further questions.
