Christian,

In your book, you explain that using JDBC batch processing is a nice thing to do for performance, but when I read the FAQ, is says to disable this feature if you're using optimistic locking. It seems that if I'm using the <version> attribute I should be okay and I could use batch. Can you help clarify this for me?

Thanks,
Lou

Can you point us to the FAQ entry? This is no longer valid.

Sure, I found that here: http://hibernate.org/117.html#A21

I actually was following this thread with interest: http://forum.hibernate.org/viewtopic.php?t=929931

Since I'm playing in the Oracle world though, it looks like I would need to create a batcher specific to Oracle. It's nice that you still batch INSERTs though. My exposure to a performance hit might not be too bad anyway, since I'm only doing a few DB calls in a particular transaction.

Thanks again,
Lou

I updated the FAQ entry. It really depends on your JDBC driver working correctly. My suggestion for Oracle is to use the DataDirect drivers, they seem to work pretty well and don't have all the quirks of the Oracle drivers. I wish Oracle would just buy them and stop torturing everyone with their Java incompetency...
