Randy Watler resolved JS2-893.
------------------------------
Resolution: Fixed
Fix Version/s: 2.1.4
PAM implementations are now capable of successfully rolling back and retrying
portlet application registrations in both the 2.2 trunk and 2.1.3-POST branch,
(to be 2.1.4).
Fixes included adding retry loop in startPortletApplication APIs and cleaning
up prefs cache in the 2.1.3-POST branch. The 2.2 trunk has a new prefs/registry
implementation that did not require any improvements based on the need to
recover successfully from failed registrations.
2.1.3 svn commit: 769669
2.2 svn commit: 769670
The new service proposed as a fix for these problems was not encorporated. A
new JIRA issue should be created to donate the service into the 2.2 and/or
2.1.4 if that is still desired.

> We developed a cluster synchronization feature that is able to synchronize
> the execution of an objects method cluster-wide. The approach is similar to
> the spring transaction proxy, so we are able to AOP-inject the cluster
> synchronization via spring configuration. The component is highly
> customizable. A new database table is used for synchonization, but any other
> data container (i.e. broadcast-distributed-hashmap) could be used.
> One main application for this functionality is the start of many jetspeed
> cluster nodes and synchronize the deployment of the PAs to the database.
> (Even with the VersionedApplicationManager we experienced DB constraints
> failures on startup with fresh database, preventing the some PAs from
> registration.)
> Patch follows (exists only for the 2.1.2-POSTRELEASE branch yet).
