hi, I am new person in this area. I can not understand yet the difference between caching in Hibernate(each type) with buffering in database such as Oracle.I would be grateful If you can explain me this or let me know where I can find comparison between these two options.

Hi Alex, I’m quite impressive with your article and your understanding on EhCache and second level cache. I’ve not done much in hibernate caching so far, but there seems to be some up coming challenges for me in my current project. So, i’m trying to lend my hands as much as i can just by reading blogs, hibernate sites, and articles like the one posted by you. Nice one!

Could you please recommend web sites, or provide me some documents you might be having on hibernate caching in a cluster based environment, appreciate, and thanks in advance.

Looks like I answered my own issue, thanks. It turns out that if part of your @NaturalId is also a @ManyToOne, any inserts on the table will flush the cache. We were able to change the relation to an Enum, and the expected behavior resumed.
