thank you for your kind answer. Actually my question was not about how
it COULD be done, but more precisely: If my customer installs Glassfish
and does not customize anything, what is the procedure he must follow to
backup or restore timers and JMS messages to prevent loss of those data
the house burns down and destroys the cluster?
Is it really necessary to do manual configuration to be able to backup
and restore this information? If yes, where is the definitive guide to
do that when using Glassfish "out of the box" (without a cluster,
without additional tools, etc.)?
This question is not about high availability but just about a simple
backup and restore of timers and queues of a single server instance.
Thanks a lot
