Head swimming with the product name soup at http://www.terracotta.org. Need someone to help clarify what I need. Background: app has some "legacy" persistence code that does not use Hibernate, but has a home-grown cache implementation. New entities are Hibernate enabled. What I want: to use Terracotta for Hibernate 2nd level cache. I t...
Is there a way to not use serialization and still use the EHCache disktore. I have nested objects , which are not serializable, which have to cached in a distributed ehcache. I can use JMS, to avoid serialization, and still achieve cache replication. But is there a way to avoid serialization to use the diskstore as well? Why isn't there...
Let's say I start with a single CacheManager like this: private static CacheManager manager = CacheManager.create(); When I call getCache or addCache do I need to synchronize on the CacheManager first? When I call put or get on the Cache, should I synchronize on the Cache first? ...
In my grails application, some of my domain classes will never be changed by Users. However, some maintenance work is sometimes necessary, and administrator should be able to create/edit few instances from time to time (let's say twice a year). I would like to set a read-only 2nd level cache strategy for these domain classes (static ma...
Hi all, I am having more problems with getting the entity manager factory up and running. Unfortunately, the error message is very vague. I'm not quite sure why it's not more descriptive, but it is what it is: Hibernate Startup log messages (trace level), no entities configured for brevity (same error message either way except all th...
Hi, I am working on a cache replication solution between nodes Node A - master node => Hibernate + Database + Ehcache as secondary cache Node B - regional node=> Ehcache as prmiary cache. no Hibernate Node B is used only as near-by cache for query. Now I am updating data (Say SudentInfo) in Node A, it gets persisted and cached correc...

Hi, I have this strange problem with ehcache 2.0 that I hope someone can help me with. I have set up a cluster of two hosts, A and B. I can see that heartbeats are received at both ends, so I'm pretty sure the networking and multicast stuff is working. The problem is that is I put an element into the cache at host A, I can see in the lo...
I'm using a cache with disk store persistence. On subsequent reruns of the app I'm getting the following error: net.sf.ehcache.store.DiskStore deleteIndexIfCorrupt WARNING: The index for data file MyCache.data is out of date, probably due to an unclean shutdown. Deleting index file MYCache.index Is there any way to fix that apart from...

I have heard of .NET APIs for memcached. Is there any equivalent for EHCache? I am envisioning a cluster of linux machines running EHCache, serving cached objects for a farm of ASP.NET webservers. Is this practical? Can this be done without installing Java on the ASP.NET servers? ...
Hi all, I am a newcomer to hibernate. It would be great if someone could comment over the following query that i have: Say i have a parent class and each parent has multiple children. So the mapping file of parent class would be something like: parent.hbm.xml <hibernate-mapping > <class name="org.demo.parent" table="parent" lazy="tru...

It's not immediately obvious to me how to set EhCache to expire an entire cache nightly/at midnight. I can easily do this programmatically via a job of some sort, but I wanted to know if there was a more "ehcache" way of doing it. Thanks in advance! ...

Hi all We are using EHCache with CF 8 to cache stuff on a central server using a RESTful interface over HTTP. I am trying to cache a cfquery object to the cache server. I can get this to work if I call EHCache direct (i.e. store it in a local cache) but if I try to cache on a remote server over HTTP I am running into problems. The co...
Context I am storing a java.util.List inside ehcache. Key(String) --> List<UserDetail> The ordered List contains a Top 10 ranking of my most active users. Problem Concurrent 3rd party clients might be requesting for this list. I have a requirement to be as current as possible with regards to the ranking. Thus if the ranking is chan...
The docs on ehache says: timeToIdleSeconds: Sets the time to idle for an element before it expires. i.e. The maximum amount of time between accesses before an element expires timeToLiveSeconds: Sets the time to live for an element before it expires. i.e. The maximum time between creation time and when an element expires. I understand...
