> Implement a second, Versioned Portlet Application Manager for clustered environments
> We are running into limitations with the NodeManager-based cluster support when deploying to clusters with replicated databases as well as replicated app servers.
> The default PAM (Portlet Application Manager) is not-appropriate for many deployments of the portal. I am implementing a second version of the PAM, with no listeners,
> and a simpler deployment algorithm based on a version number supplied in the jetspeed-portlet.xml metadata
> If this field is not found, or if it is equal to or less than the version in the database, then the PA will not be deployed.
> This will allow for dropping in 2..n PAs in a cluster, without re-registering. The problem with re-registering is that the registry algorithm deep deletes the old PA def from the database,
> create a new PA, with all new OIDs, invalidating all other PAs and portlets on other nodes in the cluster.
