Hi,david
Thanks a lot for helping me.
I am indeed using deployment based "farm" clustering to deploy to both A and B
at once.
(1)I agree with you and I think the cviewer'war should be started when node B
starts.I will open a JIRA about this.
(2)If I use the command :undeploy com.ibm.wasce.samples/cviewer/2.1.1.2/car
from node B,there is still an error:
2009-09-07 11:11:15,729 ERROR [DeployTool] Error:
org.apache.geronimo.common.DeploymentException:
com.ibm.wasce.samples/cviewer/2.1.1.2/car does not appear to be a the name of a
module available on the selected server. Perhaps it has already been stopped or
undeployed? If you're trying to specify a TargetModuleID, use the syntax
TargetName|ModuleName instead. If you're not sure what's running, try the
list-modules command.

Actually,I think because of the module is deployed by farming so it not exists
in the repository folder and that is the reason why there is an error.
Thanks a lot.

Recently,I have some questions about WADI cluster,pls help me,thanks a
lot.
I have two nodes A is the master node and B is another one.I deploy cviewer.war
in the node A and node B has the same cviewer.war.
1.If I shutdown A node first and then shutdown B node, I find that the
cviewer.war load is set false in the config.xml of node B.So when I start A and
B the cviewer.war in the node B can not work.Is it correct?
2.If I shutdown B node first and then undeploy cviewer_G_MASTER in node A,then
I startup node B, the cviewer.war's state is running and it works
well.However,I want to use the command deploy.bat undeploy in the node B to
undeploy cviewer.war there will be an error:

Is it correct?In the node B can I use some command to undeploy the module which
is deployed through WADI cluster.
Please help me ,thanks a lot.
Hi,
I think you are using deployment based "farm" clustering to deploy to both A
and B at once? This is independent of whether you are using WADI to replicate
session state between your cluster members.I am not very familiar with the
deployment based clustering, and I prefer to use plugin based clustering, which
however is only available in 2.2 (soon to be released).
(1) seems like a bug to me. I guess you can restart your app in B on the
command line or in the admin console, but I think the app should remain
started on B.
(2) deployment based clustering works by deploying a synthetic "master"
application on the controller server that manages the actual app running on
each cluster member. I think that the master app name is derived from the
actual app name by appending "_G_MASTER". So, I think you are trying to
undeploy the master app from node B, whereas it is running on node A. What
happens if you try to undeploy com.ibm.wasce.samples/cviewer/2.1.1.2/car from
node B?
thanksdavid jencks
