Ehcache is an open source, standards-based cache for boosting performance, offloading your database, and simplifying scalability.
It's the most widely-used Java-based cache because it's robust, proven, and full-featured.
Ehcache scales from in-process, with one or more nodes, all the way to mixed in-process/out-of-process
configurations with terabyte-sized caches.
Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side virtually any
Java application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to
create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are
defined as standard Java components that may execute virtually anything you may program them to do.
The Quartz Scheduler includes many enterprise-class features, such as support for JTA transactions and clustering.
Open source Terracotta Server Array (3.7) can be downloaded from terracotta-3.7.7.tar.gz.
This is compatible with Ehcache 2.6.8 and Quartz 2.1.7 only. Newer versions of Ehcache & Quartz may not be compatible with this. Terracotta no longer issues major releases of the open-source Terracotta Server Array.
Note: For in-memory data management and distributed caching, Terracotta recommends you try the BigMemory extended (90 day) trial program, which offers all of the functionality of the Terracotta Server Array and much more
Terracotta's nightly builds. These are the bleeding edge and are NOT
general-availability software. Use them only if you know what you're doing.
