Web Clustering, Integration with Terracotta, BigMemory, Quartz & Grails
summary
Terracotta/Ehcache pair ships as a TCP cluster with a web console that browses and kills sessions, and an 3.77 open-source frozen server while BigMemory Max is their commercial successor (offers a BigMemory Max 90‑day eval). Setup requires specific instrumented Ehcache/Terracotta jars — follow the version matrix — and Grails needs build config changes. Demo shows cache cold load ~3.6s then cached hit ~7ms (color cache demo: 3.6s→7ms). Quartz clustering needs matching versions: Quartz 2.1 vs 2.2 compatibility dictates using Terracotta RC7, JDBC, or BigMemory. Time sync (NTP) is critical.
