Labkey Support,
Do you have any information that can assist us in getting a clustered environment to work? We have 2 nodes and in order for changes to appear on the 2nd Tomcat node, we need to restart.
Thanks, Greg

We have had customers successfully deploy LabKey in to a cluster in a fail-over configuration (only one LabKey active at a time). However, we do not support multiple instances of LabKey running against the same database server concurrently. As you guessed this is primarily due to aggressive caching in-memory caching.

Thanks Matthew, is there a way to control caching (ie. timing to occur every minute or so) ?

No there is not. You can clear the cache entirely from the site admin console which useful for testing/debugging and above-mentioned the fail over scenario. However, this will still not enable multiple LabKey servers running concurrently. That configuration is completely untested and unsupported.
