问题 Currently we are analyzing a tomcat thread dump. A single thread dump of all threads running at that same time on a tomcat contains the following lines: ... "soldOutJmsConsumerContainer-1" prio=10 tid=0x00007f8409c14800 nid=0x231 in Object.wait() [0x00007f8403a9f000] java.lang.Thread.State: WAITING (on object monitor) at java.lang.Object.wait(Native Method) at java.lang.Object.wait(Object.java:485) at com.tc.object.RemoteObjectManagerImpl.waitUntilRunning(RemoteObjectManagerImpl.java:150) at

Is Terracota Cluster still opensource?

问题 and if yes, where it could be found?! According to this infoq entry, they have opensourced it. But right now, there is not such a product in their website. 回答1: This page, http://terracotta.org/dl/oss-download-catalog , has the links to the opensource version of terracotta and related products. You may be presented with a page requiring you to register prior to the download. I tried downloading from there yesterday, and I was able to successfully download terracotta and get it running locally

Teracotta and Hibernate Search

由 浪尽此生 提交于 2019-12-12 14:55:00
问题 Does anyone have experience with using Terracotta with Hibernate Search to satisfy application Queries? If so: What magnitude of "object updates" can it handle? (How's the performance) What kind of performance do the Queries have? Is it possible to use Terracotta Hibernate Search without even having a backing Database to satisfy all "queries" in Memory? 回答1: I am Terracotta's CTO. I spent some time last month looking at Hibernate Search. It is not built in a way to be clustered transparently

Distributed Concurrency Control

由 泪湿孤枕 提交于 2019-12-03 01:43:33
问题 I've been working on this for a few days now, and I've found several solutions but none of them incredibly simple or lightweight. The problem is basically this: We have a cluster of 10 machines, each of which is running the same software on a multithreaded ESB platform. I can deal with concurrency issues between threads on the same machine fairly easily, but what about concurrency on the same data on different machines? Essentially the software receives requests to feed a customer's data from

Ehcache Terracotta是一款由美国Terracotta公司开发的著名开源Java集群平台。它在JVM与Java应用之间实现了一个专门处理集群功能的抽象层，以其特有的增量检测、智能定向传送、 分布式协作、服务器镜像、分片等技术，允许用户在不改变现有系统代码的情况下实现单机Java应用向集群话应用的无缝迁移。使得用户可以专注于商业逻辑的开发， 由Terracotta负责实现高性能、高可用性、高稳定性的企业级Java集群 . Terracotta在2009年收购了Ehcache,Terracotta致力于继续维护Ehcache社区，并接计划保留Ehcache继续做为一个基于Apache 2许可证的开源产品. 也因此Ehcache从一个缓存框架摇身一变为一套解决方案. Terracotta也同时发布了需要付费的Ehcache企业版本,比如针对Big Memory问题,而出现的GC 停顿时间长的问题.比如Big Memory Go 和Big Moemory Max. EhCache 是一个纯 Java 的进程内缓存框架，具有快速、精干等特点，是 Hibernate 中默认的 CacheProvider。 下图是 EhCache 在应用程序中的位置： EhCache 的主要特性有： 快速； 简单； 多种缓存策略； 缓存数据有两级：内存和磁盘，因此无需担心容量问题；

JPA2.0 support of custom user-types and second level cache

由 ╄→гoц情女王★ 提交于 2019-12-01 17:49:38
问题 I'm trying to decide whether to switch from having Hibernate sprinkled all over to using JPA2.0 and thus be provider portable. 1.Does JPA2.0 support custom user-types? 2.I'm on the verge of implementing Terracotta as a second-level cache to Hibernate with its clustering abilities mainly in mind. I would imagine, but I don't actually know, that JPA2.0 also defines a spec for second-level cache providers. If I'm right, does Terracotta implement it? (If someone could point me to a getting

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 2 years ago . I am looking for a java distributed caching solution. We would like features likes: Distributed Auto-Discovery Redundancy Non-Centralized We've analyzed a framework like TerraCotta which seems to be everything we would ever want from a caching framework... However, there seems to be a central caching node(s)

问题 What is Terracotta? What services does it offer? What problems does it solve?
