1. How to monitor Hibernate statistics (cache hits and misses) in a grails app?    stackoverflow.com

By default, Grails uses Hibernate with EHCache as the second level cache. I'm still learning about how Hibernate works internally and would love to be able to introspect the caches ...

2. No more Second Level Cache hits after session.flush()    forum.hibernate.org

Beginner Joined: Tue Sep 08, 2009 9:49 am Posts: 23 Hi, I'm still pretty new to Hibernate, so maybe I understood something wrong. My application is using EHCache as the second level cache provider. I test if the cache is working properly by measuring the execution time of a SQL statement which is located in a for-loop, beeing executed 10 times. ...

3. ehcache not hits, only puts    forum.hibernate.org

Hi, I am trying to get the ehcache to work in my app, but somehow it never hits the cache, but instead it keeps on sending the same query to the MySQL database. Probably I am misunderstanding something. This is how I fetch rows from the table: Code: Client client = (Client) _session.createSQLQuery("SELECT * FROM client WHERE name = :name") ...

4. Weblogic - Small amount of Second Level Cache Hits    forum.hibernate.org

Hi All, I have an application running on weblogic using oracle db. My problem is I see very few second level cache hits when I refresh my homepage. However, when I run the application on tomcat using my oracle db and I refresh the same homepage, I see the expected second level cache hits rise as expected. Weblogic does have its ...

5. Session cache hit rate?    forum.hibernate.org

We're curious to see what kind of hit rate we're getting from Sessions, similarly to the getHitCount() and getMissCountNotFound() methods ehcache provides. Ideally, these statistics would be available both for the current Session as well as for all Sessions created by a given SessionFactory. Are others interested in this? If so, I'll file an enhancement request in JIRA.

6. ehcache caches, but doesn't hit.assigned key, no ehcache.xml    forum.hibernate.org

I had enabled query caching in my hibernate config, but HibernateTemplate has CacheQueries false by default. Setting getHibernateTemplate().setCacheQueries(true); before querying shows hits in the log. I would still be interested in whether the ehcache.xml is necessary or the defaults are acceptable? Where do you put this file in your package heirarchy assuming you put your mappings in a package called org.x.hibernate.mappings? ...

Hello everyone. I have a bit of a problem with the secound level cache. A bit lost here and not sure if it's Hibernate or Jboss. I have configured everything per the hibernate manual.

9. second level cache no hits    forum.hibernate.org

Hi everybody! I'm new to hibernate and ehcache! I want to implement a hibernate second level cache. So I try ehcache. I have created a simple table with 500 entries for test purposes.

10. Caching missed hits    forum.hibernate.org

I've only looked at ehcache, and haven't found this option. I'm wondering if anyone knows if any other cache provider has the following feature: I would like the caching provider to cache both successful lookups as well as unsuccessful lookups. Our system is such that there are many unsuccessful lookups. When using ehcache, each unsuccessful lookup initiates its own SELECT. It ...

13. L2 cache hit/miss notification    forum.hibernate.org

Hi, I'm caching native sql queries with L2 cache. Everything works fine. I'm getting cache hits, etc. There's a flaw though (probably I missed something). Everytime before I execute query I need to call db procedure which is time consuming and I'd like to avoid if possible. The scenario is as follows: if I get cache miss I need to call ...

14. hibernate second level cache "Memory cache hit, but ele    forum.hibernate.org

What does "Memory cache hit, but element expired"? I tried to do searches on this forum, but returned nothing that is helpful.. What I did is basically run the same query several times. I expected that after first time, the data should be cached so that I could get a "hit" when I run it 2nd time.. But It gave me ...

15. ehcache: many puts, no hits, no elements in memory    forum.hibernate.org

Hi, I am trying to setup ehcache with hibernate and it seems that it is not working properly. When I take a look at the generated statistics, it shows a huge number of puts (about 30.000), but only a few hundret hits and misses (about 300-400). Also, there are practically no elements in the cache (< 10). The cache has been ...
