  • 1.  Deploy war in a single node of a cluster

    Hello everyone

    I have a question, is it possible to deploy a war file in a single node of a cluster? 

    Thank you

    Hello Ismael,

    Not that I'm aware of.

    What we did for a similar situation was to define a server instance on the one node and deployed the app to that server. We did not make this server instance part of the cluster.

    I guess the point of the cluster is that it ensures the app is deployed to all nodes that are part of the cluster.

    Regards,

    As documented, "Servers that belong to a cluster are members of that cluster set and must all have identical application components deployed on them."
    Clusters and workload management - IBM Documentation
    It is not supported to have an application deployed to one cluster member only. 
    As mentioned by Sean, the best approach is to set up an additional server to host that web application. 

    Hope that helps.
