[infinispan-dev] Tweaking Infinispan Server JGroups stack values

[Galder Zamarreño]

Hey Paul/Tristan,

Say you have Infinispan Server installed locally, and you want to quickly start an instance with a lower FD_ALL.timeout, GMS.join_timeout, MERGE3.min_interval adn MERGE3.max_interval without touching the XML configuration.

Is it possible to do that? Can you pass modified parameters for these options via system properties?

I'm not looking to modify them in a particular stack but modifying them all stacks would be fine for me.

The context for this is testing topology changes for JS client. Having a cluster started and running tests continously is very convenient for me. With that in mind, a very easy way to test topology changes that does not involve restarting a process is to suspend/resume a process (Node's child processes make this pretty easy to do). My intention is try to tweak the parameters above so that timeouts are lower and hence I can quickly force a topology change.

Cheers,
